Remembering the Dodge Viper

You just changed your oil, or picked up your Jeep or Ram from a quick-lube shop, and the "Oil Change Required" message is still glowing on your dashboard. It's one of the most common questions we hear from drivers in Lee's Summit: how do I make that reminder go away? The good news is that on most Jeep, Ram, Dodge and Chrysler vehicles, resetting the oil change indicator takes less than a minute, and you don't need any tools. The short answer Most Stellantis vehicles offer two ways to reset the oil change light. Method 1: with the ignition on and the engine off, use the steering wheel buttons to go to Vehicle Info, then Oil Life, and select Reset. Method 2: with the ignition on and the engine off, slowly press the accelerator pedal all the way to the floor three times within ten seconds, then turn the ignition off. Start the vehicle to confirm the message is gone. Only reset it after the oil and filter have actually been changed. In this guide, we'll walk through both reset methods step by step, explain how the steps differ for push-button and key-start vehicles, cover what to do if the light won't reset and explain why resetting the indicator correctly matters for your engine. We'll also share tips for doing your own oil change and when it makes sense to let our Lee's Summit service team handle it. What the Oil Change Light Actually Means Before you reset anything, it helps to know what the indicator is telling you. Most Jeep, Ram, Dodge and Chrysler vehicles use an oil change indicator system, sometimes called an oil life monitor. According to Stellantis owner's manuals, the system is based on the engine's duty cycle, which means it estimates oil life from how the vehicle is actually driven, not just from mileage. When the system decides an oil change is due, it displays a message like "Oil Change Required" or "Oil Change Due," often with a single chime. After the oil is changed, the system doesn't know the job has been done. Someone has to tell it by resetting the indicator, so it can start counting down again from 100%. The oil change message is a maintenance reminder. It's different from the red oil pressure warning light, which looks like an oil can and means the engine has low oil pressure. If the red oil pressure light comes on, pull over safely and shut off the engine. Don't try to reset it. Our dashboard warning lights guide explains the difference. Before You Reset: A Quick Checklist Make sure the oil and filter have actually been changed. Resetting the indicator without changing the oil just hides the reminder. Check the oil level. Confirm the oil is filled to the correct level with the type listed in your owner's manual. Park somewhere safe with the transmission in Park. Have your owner's manual handy. Menu names and button layouts can vary slightly by model and year. Method 1: Reset Through the Instrument Cluster Menu This is the primary method on many newer Stellantis vehicles. Here are the steps from the Ram 2500/3500 owner's manual. Most Jeep, Ram, Dodge and Chrysler vehicles with steering-wheel display controls follow a very similar path. Turn the ignition on without starting the engine. Without pressing the brake pedal, push the ENGINE START/STOP button to put the ignition in the ON/RUN position. Don't start the engine. Scroll to Vehicle Info. Use the down arrow button on the steering wheel to scroll to "Vehicle Info." Open the Oil Life screen. Press the right arrow to enter Vehicle Info, then scroll up or down to "Oil Life." Select Reset. Press and hold the right arrow to select "Reset." Confirm. Press the down arrow to select "Yes," then press the right arrow to reset oil life to 100%. Exit. Press the up arrow to leave the menu. On some models, the menu may be labeled slightly differently, or you may confirm with an "OK" button instead of an arrow. If you don't see these exact labels, look for an oil life or vehicle information screen in your instrument cluster menu and check the "Engine Oil Life Reset" section of your owner's manual. Method 2: The Accelerator Pedal Reset This is the classic Mopar reset method, and it's listed in Stellantis owner's manuals as a secondary method. It works on many Jeep, Ram, Dodge and Chrysler vehicles, including those without a reset option in the display menu. For vehicles with push-button start Turn the ignition on without starting the engine. Without pressing the brake pedal, push the ENGINE START/STOP button once to put the ignition in ON/RUN. Press the accelerator three times. Slowly press the accelerator pedal all the way to the floor three times within ten seconds. Turn the ignition off. Without pressing the brake pedal, push the ENGINE START/STOP button once to return the ignition to OFF. Check your work. Start the vehicle. If the oil change message doesn't appear, the reset worked. For vehicles with a traditional key On older vehicles with a turn key, the process is generally the same: turn the key to the ON/RUN position without starting the engine, slowly press the accelerator to the floor three times within ten seconds, then turn the key back to the OFF or LOCK position. Confirm the exact steps in your owner's manual, since older models can differ slightly. Tips for the pedal method Go slowly and fully. Press the pedal all the way to the floor each time, at a steady pace. Pressing too fast or not far enough is the most common reason it doesn't work. Don't touch the brake. On push-button vehicles, pressing the brake while pushing the start button can start the engine instead of just turning on the ignition. Watch the clock. All three presses need to happen within about ten seconds. Quick Reference: Reset Methods Method Steps Best for Instrument cluster menu Ignition on, engine off; Vehicle Info, then Oil Life, then Reset; confirm Yes Newer vehicles with steering-wheel display controls Accelerator pedal (push-button start) Ignition on without the brake; press the pedal to the floor slowly three times within 10 seconds; ignition off Most push-button Jeep, Ram, Dodge and Chrysler vehicles Accelerator pedal (key start) Key to ON without starting; press the pedal to the floor slowly three times within 10 seconds; key to OFF Older key-start models; confirm in your manual Model-by-Model Notes While the two methods above cover most vehicles, here's what to keep in mind for each brand. Steps can vary by model year, trim and instrument cluster, so your owner's manual is always the final word. Jeep Most Jeep models, including the Wrangler, Gladiator, Compass, Cherokee and Grand Cherokee, support one or both reset methods. Newer models with larger digital clusters often have an "Engine Oil Life Reset" option in the instrument cluster display menu. For example, the 2023 Grand Cherokee owner's manual lists Engine Oil Life Reset under its Instrument Cluster Display section. We also have a dedicated guide for resetting the oil change light on a 2026 Jeep Compass. Wagoneer and Grand Wagoneer The Wagoneer's owner's manual also covers Engine Oil Life Reset in its instrument cluster display section. Its manual notes that an authorized dealer resets the indicator after an oil change, and that the oil should be changed within about 500 miles of the message appearing. Ram Ram 1500, 2500 and 3500 trucks typically use the instrument cluster menu method described above, with the accelerator pedal method as a backup. On Cummins diesel models, you may also see a separate "Perform Service" message for emissions-related maintenance. That's a different reminder with its own reset procedure, described in the owner's manual. Dodge Dodge Charger and Durango models generally follow the same instrument cluster or accelerator pedal methods. Performance models may have additional performance pages in their displays, but the oil life reset is usually found under vehicle information or settings. Chrysler Chrysler Pacifica owners can usually reset the indicator using the instrument cluster menu or the accelerator pedal method. Check the "Oil Change Indicator" or "Engine Oil Life Reset" section of the owner's manual for your model year. What If the Oil Change Light Won't Reset? If the message comes back when you start the vehicle, the reset didn't take. The Ram owner's manual simply says to repeat the procedure. If it still won't reset, try these fixes: Start over with the engine off. Make sure the engine is fully off before turning the ignition to ON/RUN. Don't start the engine. The reset needs to be done with the ignition on and the engine off. Slow down your pedal presses. Press the accelerator all the way to the floor each time, steadily, within ten seconds. Try the other method. If the pedal method doesn't work, try the instrument cluster menu, and vice versa. Check for other messages. If a different warning is showing, it may need attention first. Call your service department. If nothing works, the system may need to be reset with a diagnostic tool. Our technicians can take care of it quickly. When You Should Not Reset the Oil Change Light When the oil hasn't been changed. The indicator exists to protect your engine. Resetting it without changing the oil just means you'll lose track of when the next change is really due. When the red oil pressure light is on. That's a warning about low oil pressure, not a maintenance reminder. Stop driving and have the vehicle checked. When the oil level is low. Top off or change the oil first. If your oil change is overdue, our guide on how long you can drive with an overdue oil change explains what to do. Common Mistakes to Avoid Starting the engine. Both reset methods require the ignition to be on with the engine off. On push-button vehicles, pressing the brake while pushing the start button will start the engine. Rushing the pedal. Quick, partial taps often don't register. Press the pedal all the way to the floor, slowly and steadily. Resetting the wrong item. Some displays show other service reminders or trip meters. Make sure you're resetting oil life, not a trip odometer or another reminder. Forgetting to confirm. In the menu method, you usually need to select "Yes" to finish the reset. Resetting too early. Reset only after the oil and filter have been changed and the oil level is correct. Other Service Reminders You Might See The oil change message isn't the only maintenance reminder on newer vehicles. Depending on your model, you may also see: "Perform Service" on Ram Cummins diesels: a reminder for emissions-related maintenance, such as the closed crankcase ventilation filter, with its own procedure in the owner's manual. Tire pressure warnings: common when temperatures drop in the fall. Fill tires to the pressure on the driver's door placard. Low washer fluid: top off with a winter-rated fluid as the weather turns cold. If a warning or message isn't familiar, check your owner's manual or give our service team a call. Why Resetting Matters It might seem like a small step, but resetting the indicator correctly protects your engine and your wallet: It keeps your schedule accurate. The indicator can only tell you when the next change is due if it starts counting from the right point. It prevents false alarms. If the indicator isn't reset, it will keep telling you the oil is due, and you may start ignoring it, which is risky when it's actually due. It supports your maintenance records. Following the indicator, along with keeping receipts, helps show your vehicle has been properly maintained. Remember that the indicator isn't the only limit. Every owner's manual also lists a maximum interval in miles and months. For example, many Jeep gas models top out at 10,000 miles or 12 months, whichever comes first. Learn more in our guide, How Often Should You Change Your Oil? Doing Your Own Oil Change? A Few Tips Plenty of Jeep and Ram owners like doing their own maintenance. If that's you, a few tips help you do it right: Use the right oil. Stellantis owner's manuals call for specific oils, such as SAE 0W-20 full synthetic for the 5.7-liter HEMI and SAE 0W-40 full synthetic for the 6.4-liter HEMI. Check your manual or oil fill cap. Use a quality filter. A genuine Mopar filter is designed for your engine. Check the drain plug and filter seal. Make sure the old filter gasket came off with the filter, and tighten the drain plug to the correct torque. Fill to the correct level and recheck after running the engine briefly and letting it sit. Dispose of used oil properly. Many auto parts stores and local recycling centers around the Kansas City area accept used motor oil and filters. Keep records. Save receipts for oil and filters, and write down the date and mileage. Records help with warranty claims and resale value. Reset the indicator using one of the methods above. Why Let a Dealership Handle Your Oil Change? Doing it yourself works, but a dealership oil change has advantages, especially for newer vehicles: The correct oil and filter, every time, matched to your exact engine Indicator reset included, so you don't have to fiddle with menus A check of other systems, like fluids, tires, brakes and battery, while your vehicle is in the shop Recall checks, so any open recalls can be addressed during your visit Factory-trained technicians who work on Jeep, Ram, Dodge and Chrysler vehicles every day Kansas City Driving and Your Oil Life Kansas City's weather and roads affect how quickly your oil change indicator counts down. Hot summers, cold winters, short trips around town and towing season all count as tougher conditions, and the system adjusts for them. Don't be surprised if your indicator comes on sooner in the winter or after a summer of towing a boat to Lake of the Ozarks. That's the system doing its job. Frequently Asked Questions How do I reset the oil change light on my Jeep? On many Jeeps, turn the ignition on without starting the engine, then either use the steering wheel buttons to go to Vehicle Info, then Oil Life, and select Reset, or slowly press the accelerator to the floor three times within ten seconds and turn the ignition off. Start the Jeep to confirm the message is gone. How do I reset the oil life on a Ram truck? According to the Ram owner's manual, with the ignition on and the engine off, scroll to Vehicle Info, then Oil Life, press and hold the right arrow to select Reset, choose Yes and confirm. You can also use the accelerator pedal method as a backup. Why won't my oil change light reset? The most common reasons are starting the engine instead of just turning on the ignition, pressing the accelerator too quickly or not all the way to the floor, or not completing the presses within ten seconds. Repeat the procedure carefully, or try the other reset method. Can I reset the oil light without changing the oil? You can, but you shouldn't. The indicator is there to tell you when your oil needs to be changed. Resetting it without an oil change means you'll lose track of when the next change is truly due. Is the oil change light the same as the oil pressure light? No. The oil change message is a maintenance reminder. The red oil pressure warning light means low oil pressure. If it comes on, pull over safely and turn off the engine. Do I need to reset the oil light after a dealership oil change? No. At McCarthy CDJR, our technicians reset the oil change indicator as part of every oil change. How often should I change my oil? Follow your oil change indicator, and never exceed the maximum interval in your owner's manual, which for many Jeep gas models is 10,000 miles or 12 months, whichever comes first.

Most Jeep Wranglers are built to crawl. The Wrangler 392 is built to crawl and fly. Drop a 6.4-liter HEMI V8 into Jeep's most iconic off-roader and you get something that has no real rival: a trail-ready, removable-top 4x4 that can sprint from 0 to 60 faster than plenty of sports cars. It's no surprise "392 Jeep Wrangler" is one of the most searched Jeep terms out there. The short answer The Jeep Wrangler 392 is the V8-powered Wrangler. Its 6.4-liter (392-cubic-inch) HEMI V8 makes 470 horsepower and 470 lb-ft of torque, which Jeep calls the fastest and most powerful Wrangler yet. Jeep's launch figures put it at 0 to 60 mph in 4.5 seconds. After the Rubicon 392 and its Final Edition ended with the 2025 model year, the V8 returned for 2026 in two limited-edition models: the Wrangler Moab 392 and the Wrangler Willys 392. In this guide, we'll explain exactly what the 392 is, where the name comes from, how it performs on the road and on the trail, how the 2026 Moab 392 and Willys 392 differ, and how the V8 compares with the rest of the Wrangler lineup. If you're in Lee's Summit or anywhere in the Kansas City area and you've been wondering whether a V8 Wrangler belongs in your driveway, this is the place to start. What Does "392" Mean? The number is the engine's size in cubic inches. The 6.4-liter HEMI V8 displaces about 392 cubic inches, and Mopar fans have used "392" as its nickname for years. The engine has deep roots in Chrysler performance history, and it's the same family of HEMI V8 that has powered high-performance Dodge, Ram and Jeep models. Jeep's own spec sheets call it the 6.4L V8 SRT HEMI. In the Wrangler, the engine is tuned for 470 horsepower and 470 lb-ft of torque. That's a huge jump over the standard Wrangler engines, and it's the reason the 392 has become such a sought-after Jeep. The Fastest, Most Powerful Wrangler, by the Numbers Here's how the V8 stacks up against the other engines in the 2026 Wrangler lineup, using Jeep's published output figures. Engine Horsepower Torque Notes 6.4L HEMI V8 (392) 470 hp 470 lb-ft The only V8 in the class 2.0L turbo 4-cylinder plug-in hybrid (4xe) 375 hp 470 lb-ft Combined gas and electric output 3.6L Pentastar V6 285 hp 260 lb-ft The long-running Wrangler workhorse 2.0L turbo 4-cylinder 270 hp 295 lb-ft Strong low-end torque The 4xe matches the 392's torque, but the V8 delivers about 95 more horsepower and a sound no hybrid can match. When the Rubicon 392 launched, Jeep said it could run 0 to 60 mph in 4.5 seconds and cover the quarter mile in about 13 seconds. Those are remarkable numbers for a tall, boxy 4x4 on big off-road tires, and they're why the 392 has earned its "fastest Wrangler" reputation. Jeep's own press materials describe the 392 as the fastest and most powerful Wrangler yet. What it's like to drive Numbers only tell part of the story. The 392's character comes from how it delivers its power. There's no turbo lag, just instant response the moment you press the pedal, and a deep V8 rumble through a dual-mode exhaust that lets you choose a quieter or louder sound. Merging onto I-470 or US-50 feels effortless. Passing on two-lane Missouri highways on the way to the lake takes seconds, not planning. It's still a Wrangler, though. It rides on solid axles and big off-road tires, so it doesn't corner like a sports car, and its brakes and tires are tuned for the trail as much as the pavement. Think of it as an off-roader with a sense of humor, not a track car. A Short History of the V8 Wrangler The 392 has had a more dramatic history than most Jeeps, with a farewell, an encore and a comeback. 2021: The Rubicon 392 arrives. Jeep launched the first Wrangler with a factory V8, available as a four-door Rubicon only, with 470 hp, a 2-inch factory lift, Dana 44 axles front and rear with electronic lockers, Fox shocks and a functional hood scoop with Jeep's Hydro-Guide water-separating air intake. 2024: The Final Edition. In March 2024, Jeep announced the end of V8 Wrangler production and created the Rubicon 392 Final Edition as a send-off, with extra equipment and special interior details. 2025: An encore. In June 2024, Jeep announced the Final Edition would continue for the 2025 model year. After 2025, the Rubicon 392 name ended. 2026: The V8 comes back. Jeep brought the HEMI V8 back in two new limited-edition models as part of its "Twelve 4 Twelve" celebration of 85 years of Jeep. The Wrangler Moab 392 was revealed in November 2025 as the first model in the series, and the Wrangler Willys 392 followed in February 2026. Early reports from a dealer order guide suggest both V8 models will continue into the 2027 model year, but Jeep hasn't made an official announcement yet. If you've been waiting for your chance at a V8 Wrangler, the window is open now. What is "Twelve 4 Twelve"? Twelve 4 Twelve is Jeep's yearlong celebration of the brand's 85th anniversary. Jeep is revealing a new limited-edition Wrangler on the 12th of each month for 12 months. Each model has its own personality, and quantities of these special editions are limited, which is part of what makes the two 392 models so appealing to collectors and enthusiasts. Rubicon 392 vs. the 2026 V8 Models: What Changed? If you've followed the 392 since 2021, you might be wondering how the new models compare with the Rubicon 392 you remember. The heart of the vehicle is the same: the same 6.4L HEMI V8 rated at 470 horsepower and 470 lb-ft, the same eight-speed automatic and the same full-time Selec-Trac four-wheel drive. The biggest changes are in how the V8 is packaged and named: New names and personalities. Instead of one Rubicon 392, there are now two distinct models. The Moab 392 leans toward premium trail capability, and the Willys 392 leans toward heritage style and value. Simpler packaging. When Jeep introduced the Moab 392, it said it had reduced the number of mandatory options bundled into the vehicle, which made the V8 Wrangler easier to get into than the last Final Edition. Bigger tires and more clearance. Both 2026 models come standard with 35-inch tires and beadlock-capable wheels, and the Moab 392's 11.6 inches of ground clearance tops the original Rubicon 392's 10.3 inches. Limited-edition status. Both are part of Jeep's Twelve 4 Twelve anniversary series, with limited quantities. Wrangler Moab 392 vs. Willys 392: What's the Difference? Both 2026 models use the same 470-hp HEMI V8, eight-speed automatic transmission and full-time four-wheel drive. The differences come down to off-road hardware, styling and features. The Willys 392 is the lower-priced of the two and takes a classic, back-to-basics approach, while the Moab 392 adds more trail equipment and premium touches. Feature Moab 392 Willys 392 Engine 6.4L HEMI V8, 470 hp / 470 lb-ft 6.4L HEMI V8, 470 hp / 470 lb-ft Transmission 8-speed automatic 8-speed automatic 4x4 system Selec-Trac full-time 4WD Selec-Trac full-time 4WD Axles Dana 44 heavy-duty, 4.56 ratio Dana 44 heavy-duty, 4.56 ratio Rear locker Electronic Tru-Lok Electronic Tru-Lok Front locker Electronic Tru-Lok Conventional front differential Front sway bar Electronic disconnect Fixed Tires 35-inch BFGoodrich all-terrain 35-inch BFGoodrich KO2 Ground clearance 11.6 inches 11.1 inches Hardtop Body-color three-piece, standard Black three-piece, available Interior Nappa leather, Alpine audio, 12.3-inch Uconnect NAV Nappa leather, Alpine audio, 12.3-inch Uconnect NAV Choose the Moab 392 if: You plan to tackle serious rock crawling or technical trails, where front and rear lockers and a disconnecting sway bar make a real difference. You want the most premium V8 Wrangler, with a body-color hardtop and more available features. You want the extra ground clearance. Choose the Willys 392 if: You want V8 power and heritage styling, with Willys hood graphics, at a lower price. Your off-roading is mostly gravel roads, campgrounds, mud and moderate trails, where a rear locker and 35-inch tires are plenty. You'd rather put money toward accessories, lift kits or your own customizations. What Makes the 392 So Capable Off-Road A big engine would be wasted without the hardware to back it up. Here's what the V8 Wranglers bring to the trail: Selec-Trac full-time four-wheel drive with a 2.72:1 low range, so you can drive in 4WD on mixed surfaces and still crawl slowly over obstacles. Heavy-duty Dana 44 axles, including a full-float rear axle on the Willys 392, built to handle the V8's torque and 35-inch tires. Electronic locking differentials that force both wheels on an axle to turn together for maximum traction. 35-inch tires on beadlock-capable wheels, which allow serious off-roaders to run very low tire pressures. A functional cold-air intake hood with a water separator, which helps keep water out of the engine during water crossings. The original Rubicon 392 was rated for up to 32.5 inches of water fording, and the Moab 392 is reported at 34.5 inches. Rock rails and steel bumpers, including a winch-capable front bumper. The V8 advantage on the trail The 392's torque is useful off-road, not just on the highway. It can pull up steep climbs and through mud and sand with less throttle and less drama. Off-road drivers often say a big, smooth V8 makes it easier to control wheel speed on loose terrain. Combined with the low-range gearing, it gives the 392 both strength and finesse. Living With a V8 Wrangler Every Day The 392 is a blast, but it's also a real daily driver for plenty of owners. Here's what to know before you buy. Fuel Jeep recommends premium fuel, rated 91 octane or higher, for the 6.4L V8. Fuel economy is lower than the other Wrangler engines, which is the tradeoff for the power. If most of your driving is a daily commute around Lee's Summit or into Kansas City and fuel costs are a priority, the 2.0L turbo, the V6 or the 4xe may suit you better. Body style Every V8 Wrangler is a four-door Wrangler Unlimited, so there's room for passengers and gear. If you've been searching for the "biggest Jeep Wrangler," it's the four-door Unlimited, and the 392 models add a bit more height with their 35-inch tires and off-road suspension. Towing The Willys 392 includes Jeep's Trailer Tow Package, so it's ready for a small utility trailer, a pair of dirt bikes or a small boat. The Wrangler isn't built to be a heavy-duty tow vehicle, though. If towing a large camper or boat is a priority, take a look at the Jeep Gladiator or a Ram truck, or check our guide to half-ton vs. three-quarter-ton vs. one-ton trucks. Kansas City winters Full-time four-wheel drive and big all-terrain tires make the 392 confident in snow and slush. Keep in mind that powerful engines and big tires call for a gentle right foot on icy roads. Take it easy, and the Selec-Trac system will do the rest. Maintenance The V8 Wranglers need the same routine care as any Jeep: oil changes, tire rotations and regular checks of the 4WD system, axles and suspension, especially if you spend time off-road. Our service team in Lee's Summit is trained on HEMI engines and Jeep 4x4 systems. Our guide to oil change intervals is a good place to start. Making it your own Part of the fun of any Wrangler is personalizing it, and 392 owners are no exception. Popular first additions include all-weather floor liners for muddy boots and snowy Kansas City winters, auxiliary lighting wired to the factory auxiliary switches, recovery gear like traction boards and a recovery kit, and a winch for the winch-capable front bumper. Some owners add a cargo management system or a rooftop rack for camping trips. Genuine Mopar accessories are designed specifically for your Jeep, and our parts team can help you choose what fits your plans. Is a Wrangler 392 Right for You? The 392 isn't for everyone, and that's part of its appeal. Here's a quick way to decide. A 392 is a great fit if you: Want the ultimate Wrangler, with the most power Jeep has ever put in one Love the sound and feel of a V8 and know it may not be around forever Spend weekends on trails or at off-road parks and want serious hardware from the factory Want a limited-edition Jeep that stands out in any parking lot Consider another Wrangler if you: Want the best fuel economy and quiet electric driving, where the 4xe makes more sense Want a two-door Wrangler or a lower starting price Mostly drive on pavement and don't need 35-inch tires Still deciding? Our team can put you behind the wheel of different Wrangler models so you can feel the difference for yourself. If you're also cross-shopping a Gladiator, ask us about that, too. It's the same Jeep spirit with a pickup bed. Shopping for a Wrangler 392 Near Lee's Summit Because the Moab 392 and Willys 392 are limited editions, availability can change quickly.

Buying a pre-owned Rubicon 392 or Final Edition A used Rubicon 392 can be a great way into a V8 Wrangler, but because many of these Jeeps are driven hard off-road, it pays to look closely. Before you buy, check: Service records, especially regular oil changes for the V8 and fluid changes for the axles and transfer case. Underbody condition, including skid plates, rock rails, control arms and the steering components, for signs of hard trail use. Tires and alignment, since uneven wear can point to suspension or steering issues. Aftermarket modifications, like lift kits, tuners or exhaust changes, which can affect reliability and warranty coverage. Open recalls, which you can look up by VIN on the NHTSA website. A certified pre-owned Jeep from a franchised dealer has gone through a detailed inspection, which can take a lot of the guesswork out of buying a used V8 Wrangler.

There's never a good time for a dead battery, but a 10-degree January morning in a Lee's Summit driveway, with the kids already late for school, might be the worst. You turn the key or press the start button and get a slow, tired groan, a rapid clicking or nothing at all. The frustrating part is that most batteries give warning signs for weeks before they finally quit. The short answer The biggest warning signs are a slow or labored start, clicking when you try to start, dim or flickering lights, electrical glitches, a battery warning light, a swollen or corroded battery, and age. Most car batteries last about 3 to 5 years, and cold weather can cut a battery's strength by about 35% at 32°F and about 60% at 0°F. If your battery is 3 or more years old, get it tested before the first hard freeze. In this guide, we'll walk through the seven signs that your battery is on its way out, why Kansas City's hot summers and cold winters are so tough on batteries, how to check yours at home and what to know about the batteries in today's Jeep, Ram, Dodge and Chrysler vehicles. We'll also help you decide whether a weak battery is just a quick fix or a sign it's time to think about your next vehicle. Whether you drive around Lee's Summit, commute from Blue Springs or Raymore, or head into Kansas City every day, a few minutes now can save you a cold morning stranded later. Why Winter Is Hard on Car Batteries A car battery makes electricity through a chemical reaction, and that reaction slows down as temperatures drop. At the same time, a cold engine is harder to turn over because its oil is thicker. So in winter, your battery has less power available at the exact moment your engine needs more. According to AAA, a battery loses about 35% of its strength at 32°F and about 60% at 0°F, and starting an engine in cold weather can take up to twice the normal current. That's why a battery that seemed fine in October can suddenly fail on the first frigid morning of the year. Here in the Kansas City area, January's average low is about 24°F, and lows occasionally dip into the single digits. That's cold enough to expose any battery that's been quietly weakening. Summer heat does the real damage Here's what surprises a lot of drivers: heat is actually harder on batteries than cold. Consumer Reports explains that high temperatures speed up the chemical breakdown inside a battery, and the heat under the hood makes it worse. Our hot, humid Missouri summers do the damage, and the first cold snap reveals it. That's why the timing matters. If your battery made it through a long, hot summer, fall is the perfect time to find out how much life it has left, before winter does it for you. 7 Signs Your Car Battery Is Dying If you notice one or more of these warning signs, have your battery tested soon. Most are easy to spot once you know what to look for. 1. Your engine cranks slowly This is the most common early warning. Instead of a quick, crisp start, the engine turns over slowly and sounds sluggish, almost like it's struggling to wake up. It's usually most noticeable on cold mornings or after the vehicle has been parked for a day or two. A slow crank means the battery is having trouble delivering the burst of power the starter needs. It may still start today, but it's telling you it won't for much longer. 2. You hear clicking when you try to start A rapid clicking sound when you turn the key or press the start button usually means the battery has enough power to engage the starter's switch, but not enough to actually spin the engine. A single click can point to a starter problem instead. Either way, it's time for a test. If you've needed a jump start more than once recently, that's a strong sign the battery or charging system needs attention. 3. Your headlights and interior lights are dim AAA lists dim or yellowish headlights, and dome lights that are dim or flicker, as warning signs of a weak battery. You might notice headlights that brighten when you rev the engine, or interior lights that dim when you start the vehicle. Modern LED lights can hide this a bit, so pay attention to other clues, too. 4. Electronics act strangely Today's vehicles are full of electronics, and they need steady voltage to work properly. A weak battery can cause the radio or touchscreen to reset, power windows to move slowly, a weaker-sounding horn, phone chargers that stop working or random warning messages on the dash. AAA notes that the growing number of electronics in vehicles is one reason batteries may last closer to three years than five. On many newer Jeep, Ram, Dodge and Chrysler models, you may also notice that the engine Stop/Start feature stops shutting the engine off at red lights. The system has many conditions that can keep it from activating, and a low battery charge is one of them. If it stops working and nothing else has changed, mention it when you have the battery tested. 5. The battery warning light comes on The red battery-shaped warning light on your dash means the battery isn't being charged properly. That can be the battery itself, but it often points to the alternator, a belt or wiring in the charging system. Either way, the vehicle may be running on battery power alone, and it could stall when the battery runs down. Turn off nonessential electronics and get it checked right away. Our guide to Jeep dashboard warning lights explains this and other red lights in detail. 6. The battery looks swollen, cracked, leaking or corroded Pop the hood and take a look. Warning signs include: A swollen or bulging case: often caused by heat or overcharging, and a clear sign the battery needs to be replaced. Cracks or leaks: battery acid is dangerous. Don't touch it with bare hands. White, blue or green crust on the terminals: corrosion can block the flow of electricity and make a healthy battery act like a weak one. Light corrosion can often be cleaned off, but if the battery itself is damaged, replace it. 7. It smells like rotten eggs, or the battery is simply old A sulfur or rotten-egg smell near the battery can mean it's leaking or overheating. Treat it seriously and have it inspected soon. And sometimes the clearest warning sign is the calendar. AAA puts a typical battery's life at about three to five years, and lists being more than three years old as a warning sign by itself. Consumer Reports notes that batteries tend to last longer in colder northern states and wear out faster in hot southern ones. Kansas City's mix of hot summers and cold winters gives batteries a workout in both directions. If yours is three years old or more, get it tested this fall, even if it seems fine. How to Tell How Old Your Battery Is Most batteries have a date sticker or stamp on the top or side. Consumer Reports explains that the code usually shows the month and year it was made. It might look like "10-8" (numbers) or "K-8" (a letter for the month, with A for January and the letter I skipped). Some show a full date instead. If you have service records, your receipt will also show when the battery was installed. And if you bought a used vehicle and don't know the battery's history, it's worth having it tested sooner rather than later. How to Check Your Battery at Home A quick visual check and a simple voltage reading can tell you a lot. Here's how: Turn the engine off and let the vehicle sit for at least a few hours, ideally overnight, so you get a true resting reading. Look the battery over for swelling, cracks, leaks and corrosion on the terminals. Check the connections. The cables should be tight and shouldn't wiggle on the posts. Use a multimeter set to DC volts. Touch the red lead to the positive (+) terminal and the black lead to the negative (−) terminal. Read the voltage. As a general guideline, a fully charged 12-volt battery reads about 12.6 volts or a bit higher at rest. Around 12.4 volts is roughly three-quarters charged, and 12.2 volts or lower suggests the battery is low and needs charging and a proper test. Some vehicles can also show battery voltage in the instrument cluster's vehicle information menu. Check your owner's manual to see if yours does. Why a professional test is better A voltage reading only tells you how charged the battery is, not how healthy it is. A battery can show a full charge and still fail under load on a cold morning. A professional battery test measures how well the battery delivers power under load, which is what actually starts your engine. AAA recommends having a technician check the battery, starter and alternator together, since a weak alternator or starter can look a lot like a bad battery. What's Different About Batteries in Newer CDJR Vehicles Batteries aren't one-size-fits-all anymore, and that's especially true on today's Jeep, Ram, Dodge and Chrysler models. Stop/Start vehicles need the right battery type Vehicles with automatic engine Stop/Start restart the engine many times on every drive, which puts extra demand on the battery. They typically use an advanced battery, such as an AGM (absorbent glass mat) battery. Battery maker VARTA notes that a Stop/Start battery should be replaced with the same type, and that a conventional battery isn't an acceptable substitute because it would wear out quickly. Installing the wrong battery can also cause the Stop/Start system or other electronics to act up. Some vehicles have more than one battery Depending on the model and equipment, your vehicle may have an auxiliary battery in addition to the main one. Plug-in hybrids like the Jeep Wrangler 4xe and Grand Cherokee 4xe have a large high-voltage battery for electric driving, but they also have a separate 12-volt battery that powers the low-voltage systems, according to Jeep's emergency response guide. That 12-volt battery can still weaken with age, just like in a gas vehicle. Mild-hybrid systems Some Ram 1500 and Jeep models have used a 48-volt mild-hybrid system, often called eTorque, to help with smooth Stop/Start operation and add a little torque. These vehicles still have a standard 12-volt battery as well. Replacing or servicing the high-voltage or 48-volt components is a job for trained technicians. The takeaway: when your battery needs replacing, make sure it's the correct type and size for your exact vehicle. A certified Mopar technician will match the battery to your vehicle's specifications. How to Make Your Battery Last Longer You can't stop a battery from aging, but you can slow it down and avoid surprises: Get it tested every fall once it's three years old, and every year after that. Keep the terminals clean and tight. Corrosion and loose cables waste power. Avoid lots of very short trips. Short drives don't give the alternator time to fully recharge the battery, especially in winter when heaters, defrosters and heated seats are running. Drive regularly. If a vehicle sits for weeks, a battery maintainer can keep it charged. Turn off lights and accessories when the engine is off. Unplug dash cams and other devices that draw power while parked. Park in a garage when you can. It helps in both the summer heat and the winter cold. Keep a jump starter in the vehicle. A compact jump pack is an inexpensive way to avoid being stranded. What to Do If Your Battery Dies If it happens, stay calm and stay safe: Check the basics. Make sure the vehicle is in Park and that interior lights or accessories weren't left on. Jump-start it carefully using the procedure and connection points in your owner's manual. Some vehicles specify particular jump-start points under the hood, which may not be the battery itself. Drive it straight to a service department or let it run long enough to recharge, but don't assume the problem is solved. A battery that died once is likely to do it again. Get the whole charging system tested, including the alternator and starter. If you smell rotten eggs, see the battery swelling or notice leaking, don't try to jump-start it. Call for help instead. Your Quick Winter-Ready Checklist While you're thinking about the battery, take care of the other things that make Kansas City winters easier. A few minutes now can prevent a breakdown on a snowy morning on I-470 or Highway 291. Check Why it matters in winter Battery test Cold weather exposes weak batteries first. Tire pressure and tread Pressure drops as temperatures fall, and worn tread loses grip on ice and slush. Wiper blades and washer fluid Road salt and slush make clear visibility essential. Use a winter-rated washer fluid. Coolant The right coolant mix protects against freezing and keeps the heater working. Oil change Fresh oil flows better on cold starts. See our guide on overdue oil changes. 4WD system check Make sure four-wheel drive engages properly before you need it in the snow. Emergency kit Pack a blanket, gloves, flashlight, ice scraper, phone charger and a jump starter. Battery Trouble on an Older Vehicle? It Might Be Time to Upgrade A new battery is often a quick, simple fix. But sometimes a dead battery is the first of several repairs adding up on an aging vehicle. If your car or truck also needs tires, brakes or bigger work this winter, or it just isn't as dependable as it used to be, it's worth comparing the cost of repairs to the benefits of something newer. Newer Jeep, Ram, Dodge and Chrysler models offer features that make Kansas City winters easier, like remote start on many models to warm up the cabin before you head out, heated seats and steering wheels, four-wheel drive and all-wheel drive for snowy roads, and advanced battery management to help keep electrical systems charged. A new vehicle also comes with a factory warranty, and a certified pre-owned vehicle has passed a detailed inspection. If you're on the fence, our team can appraise your current vehicle so you know what it's worth as a trade-in before you decide anything. Ask about a trade-in appraisal when you come in for a battery test, and you'll have both answers in one visit. Frequently Asked Questions How long does a car battery last in Missouri? Most car batteries last about three to five years. Hot Missouri summers speed up wear, so many drivers in the Kansas City area find their batteries need replacing toward the shorter end of that range. Have yours tested once it's three years old. Why does my car battery die in cold weather? Cold slows the chemical reaction that produces power, so a battery loses about 35% of its strength at 32°F and about 60% at 0°F, according to AAA. At the same time, a cold engine needs more power to start. A battery that's already weak may not be able to keep up. Can a battery die without warning? It can, especially if heat has damaged it internally. But most batteries show signs first, like a slow crank, dim lights or electrical glitches. A load test can catch a weak battery before it leaves you stranded. Is it the battery or the alternator? If the vehicle starts with a jump but dies again soon after, or the battery warning light comes on while driving, the alternator or charging system may be the problem. If it starts slowly after sitting but runs fine once started, the battery is the more likely culprit. A technician can test both. Do I need a special battery for a vehicle with Stop/Start? Yes. Vehicles with automatic Stop/Start typically use an advanced battery, such as an AGM battery, and should be fitted with the same type when it's replaced. A conventional battery may wear out quickly and can cause the Stop/Start system to act up. Should I replace my battery before winter even if it still works? If your battery is three or more years old, it's smart to have it load tested in the fall. If the test shows it's weak, replacing it before the first hard freeze is much easier than dealing with a no-start on a cold morning. If it tests healthy, you can keep using it and test it again next year. How long does a battery replacement take? For most vehicles, a battery test and replacement is a quick service visit. Some newer vehicles have batteries in harder-to-reach locations or need additional steps after installation, which can add a little time.
