2024 Jeep Wrangler: check engine light

Filed Nov 4, 2026 · WA

1/9/26 my 2024 Jeep Wrangler 4xe received the 68c recall check. The dealership said they flashed it, and that it was perfectly fine. Up to that point I had not had a single issue since I purchased it in July '24. Headed home, 5-6 miles up the highway my vehicle started to slow; dropped from 63 to mid 50's and then surged. It was ok for a few seconds then it did it again. I was approaching a hill and had 12% battery. I immediately pulled off the highway, called the dealership and said I was turning around and bringing it back. I turned off electric mode, turned on my hazards and drove slowly back to the dealer. They asked if there was a light on, there wasn't. They hooked it up to run a diagnostic and got no codes so nothing was wrong, probably just the engine shifting from electric to hybrid, perfectly normal. Since then it has happened several more times, all when either it is very windy or going up a hill/incline. I keep getting told nothing wrong. When I bring up the 68c recall, they said they hadn't heard of an issues. So I've just dealt with it. Oct 29 in for recall 21d. Had them look into the deceleration issue; on Oct 28 happened again, but this time my check engine light was on. Oct 31 told everything good, CE light likely gas cap and they did 2 software updates that should take care of the power issue. I was good to go. Today, Nov 4, I went to leave and got a key fob not detected error. I grabbed my spare, which has never been used, and tried again. It showed, hold fob to start/stop and press. I did that and the dash lit up like the 4th of July. Dash lights flashing, gauges were clicking, radio screen was blinking on and off, the engine did not engage. Tried again and just went black. Zero power. Towed to dealership and told likely the 12v battery is depleted, but it's just coincidental that it happened right after another recall. A single Google search showed it's a well known safety issue. Filed complaint with Jeep Wave. Case #98538803

My jeep has been in the shop MULTIPLE times for a check engine light. Approximately 7-8 times. I've always been told, it's just giving 2-3 different codes and it's nothing to worry about. About a month ago, I was driving my Jeep and it just stopped running. I was sitting in the middle of a very busy intersection. I could not put it in natural to push it to the side of the road, I couldn't get it started, it was just doing nothing. For approximately 45 mins It sat in the middle of an intersection with people yelling at me, beeping at me, etc... When my wife arrived to help me get my stuff out of the vehicle, I tried it one more time and it started up. I then drove it immediately to the dealership. Every light on the dashboard was lit up and the engine was revving like a lawn mower. Got it to the dealership AGAIN was told the whole EV battery needed to be replaced. It's a 2024 Wrangler 4XE with around 15,000 miles on it. I think it's been in the shop longer than I've actually driven it the past couple of year. I will never buy another Jeep product.

2024 Jeep Wrangler 4xe models. Sudden loss of power while driving up hill in the electric mode. It would not go over 59 miles per hour and then it switched over to hybrid all on its own. This happened a few times and I could not go fast enough on the freeway. The next week the check engine light was on along with, engine warning light: service battery charging system and it would not start. I have a 2024 Jeep Wrangler 4xe Sahara. All recalls are up to date. My jeep suddenly lost acceleration while I was driving. It happened more than once, including a frightening situation when my vehicle rapidly slowed from approximately 65-59-45. My Jeep was subsequently towed to the dealership.

I own a 2024 Jeep Wrangler 4xe Sport S that has experienced a significant and potentially dangerous reduction in propulsion power following the completion of Recall 68C (the federal safety agency Campaign 25V741000) by an authorized Jeep dealership. These problems began after the recall software update and were not present beforehand. Since the recall repair, the vehicle has substantially reduced electric-motor acceleration. While operating in Electric mode, pressing the accelerator can result in an increase of only approximately 1 MPH every 1–2 seconds, even with substantial accelerator input. The internal combustion engine (ICE) then engages prematurely at unusually high RPMs to compensate for the lack of electric propulsion. This results in delayed and inconsistent acceleration. Additionally, the vehicle struggles to accelerate beyond approximately 55 MPH while operating in Electric mode. When attempting to accelerate further, the vehicle eventually displays "Electric Mode Not Available" and disables Electric mode for the remainder of the drive. Before Recall 68C, the vehicle operated at highway speeds in Electric mode without these limitations. Despite these repeatable symptoms, the vehicle does not illuminate a check-engine light or produce observable diagnostic trouble codes. The electric propulsion and powertrain systems remain installed and available for inspection. The cause has not been independently confirmed. These conditions create a serious safety concern when merging onto highways, crossing intersections, or accelerating with surrounding traffic. The vehicle responds very slowly to accelerator input before abruptly engaging the gasoline engine at high RPMs. This unpredictable behavior creates a potential collision hazard. I request that the federal safety agency investigate whether the Recall 68C software update is contributing to reduced propulsion power, delayed acceleration, and unexpected Electric-mode deactivation in affected Jeep Wrangler 4xe vehicles.

After completing the 68c recall, one week later, my Wrangler got the red turtle message and the check engine light came on. I lost power and the fan went on full power and sounded like a jet engine. Lost power on the highway. It has been at the dealer for 4.5 weeks and still has not been looked at to diagnose. No loaner. No rental. Nothing. It is unsafe to drive so it has to be left at the dealer.

2024 Jeep 4XE Wrangler Rubicon, 3 recalls, 1st EV battery, potential fire hazard, 2nd Sand in the engine, potential fire hazard, 3rd wiring harness for steering unit, potential fire hazard, all of them can cause a fire with it being parked and not even plugged in for charging. FCA sent out the recall notices, and later said they had remedies, the problem is the remedies aren't remedies at all. I was at my dealership 2 days ago talking to my service writer, and he told me that another customer with the same vehicle passed the so called remedy for sand in the engine, a few days later his engine light came on, and now the dealership is replacing his engine, with that being said doesn't that mean that even with a passed so called remedy, it could still be a fire hazard. I have had all the recalls done at my dealership, but I don't feel that they are being honest about any of these remedies actually working, and that everytime I get in the vehicle or park it I'm afraid that it could still catch fire. I have a vehicle that has been taken off the market by the manufacturer, and has told the dealerships not to sell them, I have tried to get some reimbursement, but have had no luck, am hiring an attorney to try to get something done.

I purchased my Jeep Wrangler 4xe on Sept. 27, 2025 thinking all battery issues were addressed by the manufacturer. Then a month later the 68C hybrid battery recall is issued. My hybrid battery passed the 68C recall on Dec. 22 at the dealership. Ensuing 78C and 21D recalls meant I couldn't park in my garage and charge my vehicle for weeks at a time. My electric motor would not start on Aug. 11. Check engine light on, electric mode unavailable and AC not working. Then the vehicle forced itself into park while reversing to be towed to the dealer and died in the street. These vehicles are dangerous because there is no warning when they stop working. They just stop - sometimes in traffic or the middle of the street. With 68C, we were led to believe that only some batteries would have issues and that the installed software would monitor battery health. What we began to see was the batteries were structurally deficient and ALL batteries would fail at some point. The software was designed to shut the vehicle down if it detected a fault. Post 68C recall, many owners experienced a decrease in the performance of their Jeeps as the internal computer sought to balance battery load. This meant we weren't getting the MPG advertised and promised. We also received a warranty extension of unlimited miles and unlimited years. BUT, the fine print says the battery will be replaced ONLY if the value of the vehicle is more than the cost to replace the battery. My jeep has lost $14,000 in value in less than a year while I put less than 10,000 miles on it. The dealer has had my vehicle for a month and confirmed the hybrid battery is the problem. They have ordered a new one, but the new ones have the same defect. Owners are also seeing additional electrical faults after a hybrid battery replacement.

On August 26, 2026, my 2024 Jeep Wrangler 4xe, with approximately 32,000 miles, experienced a sudden loss of power while my family and I were driving. The vehicle lost power in an intersection, creating a serious safety hazard with surrounding traffic. We were stranded until help arrived, and the vehicle had to be towed because it would not restart. Before the loss of power, the A/C stopped blowing cold air. The check-engine light came on, dashboard components and warning indicators began flashing, the battery warning light appeared, and a “Service Charging System” warning was displayed. This was not simply an inconvenience. The sudden loss of power left us unable to move the vehicle in an intersection and created a significant risk of being struck by another vehicle, potentially causing serious injury or death. I am a military veteran, and this incident caused a severe stress and trauma response because I believed my family's safety and my life were in danger. I am requesting that the federal safety agency investigate whether this incident is related to a safety defect involving the charging system, electrical system, hybrid propulsion system, battery system, power electronics, software, or another component capable of causing sudden loss of motive power. I understand the federal safety agency has previously investigated loss of motive power involving Jeep Wrangler 4xe vehicles. I am reporting this incident so it can be included in the federal safety agency's safety data and evaluated for a possible broader safety defect. I can provide the VIN, towing records, photographs/videos of the warnings, diagnostic trouble codes, dealership findings, and repair records. I respectfully request that the federal safety agency document and investigate this safety complaint and determine whether further action or a safety recall is warranted.

In June 2026 the 2024 Jeep Wrangler Sahara 4xe power shut down along with service engine light in two seperate instances while my son was driving at highway speed. I made the dealership aware and had the vehichle checked out. They said nothing wrong with vehichle. On July 25 2026 I was driving vehichle on highway and cruise control came on by itself along with service engine light. I had no power to accelerate. I had to pull over and shut car down before proceeding. I brought the vehichle to Paul Bailey dealership and they grounded the car on 8/7/2026 when Stellantis agreed to pay for a rental car.
