Jeep Wrangler check engine light comes on

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

The Jeep was purchase used from a Jeep dealer in April 2026. At 42,821 miles it was still under the manufactures warranty. We have had multiple occurrences where the check engine light comes on, followed by other warning lights, and moments later the Jeep will stall in traffic. When it stalls, it is unable to be restarted or shifted to neutral to be pushed out of traffic. This has cause multiple seriously dangerous situations and collision close calls. Sometimes a jumpstart will allow the vehicle to be restarted. other times it must be towed. Note: The battery and electrical systems checks indicate no failures even though the battery/low voltage warning lights come on during the incidents. I have taken the vehicle to four different repair facilities including authorized Jeep dealer service centers. The first three times parts were replaced. The fourth time it was towed to Santa Monica Jeep. They verified the same error codes as reported previously then cleared the error codes. One they cleared the error codes, they were unable to get the check engine light to come back on during their short test drives. And none of the components were testing as bad. So I requested a Stellantis field technician inspect the vehicle. They were also unable to diagnose the problem even though it keeps recurring. Because they were unable to diagnose the problem, they refused to take any further action, even though the service manager told me that the vehicle is unsafe to drive. I informed my insurance company of the situation and they told me that they may not cover any claims unless the dealer provides a "Certified Mechanics Statement" or "proof of repairs showing that the vehicle is in good physical condition and safe to operate." The dealer refuses to provide this. So now I have a Jeep that is unsafe to drive, may no longer e covered by my insurance, and neither a Jeep dealer nor Stellantis themselves are willing to resolve a dangerous stalling problem.

I am reporting repeated safety-related failures involving my 2023 Jeep Wrangler 4xe Sahara 4x4, VIN 1C4JJXP62PW524360. The vehicle has experienced recurring failures involving the high-voltage battery, hybrid charging/propulsion system, electric coolant heater, and battery thermal-management system. On 7/17/2025, at about 60,291 miles, the vehicle displayed a check-engine light and “Service Charging System” warning. While stopping, the vehicle shut off and would not restart without assistance. A/C stopped working and EV operation was unavailable. The dealer performed FCA 95B high-voltage-battery recall/software work. The problem returned. From 8/8/2025 to 9/12/2025, at 61,447 miles, the dealer diagnosed DTC P0B24, “Hybrid/EV Battery ‘A’ Voltage Unstable,” and documented an internal high-voltage-battery failure causing intermittent no-start conditions. The complete HV battery was replaced. The vehicle was out of service about 35 days. On 10/8/2025, electric mode again became unavailable/intermittent. The dealer diagnosed P0E15-00 and replaced the electric coolant heater. From 10/13/2025 to 10/17/2025, the check-engine light returned after charging; the dealer repaired a coolant-bypass/air-lock condition in the hybrid cooling system. From 6/30/2026 to 8/7/2026, at 80,222 miles, the vehicle returned for “Service Hybrid System” and EV-charging concerns. FCA 68C PHEV HV Battery Fires recall work was performed, and the electric coolant heater was again diagnosed as failed and replaced. The vehicle was out of service about 38 days. On 9/9/2026, Driver’s Village advised that the high-voltage battery requires complete replacement again. This would be the vehicle’s second complete HV-battery replacement. These major hybrid-related repair episodes total at least about 77 documented days out of service. My primary safety concerns are shutdown/no-start, repeated charging/hybrid-system warnings, failure of the original HV battery, continued failures after recall remedies,

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.

The check engine light was on and it said to service the battery charging components. When driving in hybrid mode it doesn’t switch to use the battery. When I was trying to pull off after stopping, the jeep hesitated and would not move and then all of a sudden jerked and took off almost making me crash and people crash into me.
