Filed Nov 2, 2026 · Electrical · OH

The vehicle has lost power multiple times and have been at the dealership now twice due to it first time the check engine light went off before the dealership could find an issue and they couldn’t find anything second time after losing power on the expressway. They check engine light came on for a few days and went off by time my appointment at the dealership. The determined the PIM had issues and are replacing it.

After the recall on the hybrid battery and getting it replaced, I have experienced loss of power, especially when merging onto a highway, I don’t have acceleration like I did before. Sometimes the vehicle will “fall on its face “when going to pass another slow vehicle I feel like this is extremely dangerous when trying to maneuver into traffic

While towing a utility trailer on the highway, the vehicle suddenly lost acceleration and could not maintain normal power while the driver was attempting to pass a semi-truck. During the incident, the semi-truck contacted the trailer and shredded one of the trailer tires. Three occupants were inside the vehicle. No injuries occurred, but the incident created a serious risk of a fatal collision. The vehicle has repeatedly displayed “Service Electronic Stability Control” and other warning lights, together with loss of power and transmission hesitation/slipping. The same concern has been reported to the dealership during approximately three service visits. The dealership previously replaced the air filter and attributed the warning lights to it, but the condition returned. Dated videos show the warning condition before and after that repair. The vehicle is currently back at the dealership for the recurring safety concern.

In electric mode vehicle loses battery power (at 25% power draw)and several seconds later starts the gas engine to compensate. It does this at least once within every full charge (about 28 miles)-usually when the remaining charge is between10-20%, but on occasion it happens at around 50% and at least once when the battery showed 80%. When it happens at lower charge, it continues until the charge is 0 and it switches to hybrid mode. When the remaining charge is higher it will continue to lose power/start engine and then shut engine off for several miles and then revert to acting normally again. There is no indication on the dash that there is a problem. The jeep does not revert to hybrid mode -it stays in electric mode. This is repeatable. It happens at least once every full charge...usually while accelerating from a stop. I've had it lose power while accelerating through an intersection for several seconds before the engine starts...UNSAFE. Jeep dealer said no fault codes/software is up to date -so nothing they can do. On the phone, the rep said they have no way to troubleshoot this problem.

After 68C my Jeep doesn't respond the way it used to, theres reduced power when staying with the flow of traffic or climbing hills. It seems to be unsafe bc I can't accelerate like I used to, I think Jeep is limiting the power

I was driving and had a sudden loss of power. My gas pedal would not respond. I had to put my car in park and out of hybrid so my gas engine would come on.

After completing the Jeep Wrangler 4XE '68C' recall, my Wrangler started having erratic RPM / engine surges. Moreover, the powertrain system will jump between electric and hybrid gas (ICE) modes while driving at highway speeds when in 'Electric' mode. It actually does this in Hybrid mode but Electric mode is far worse. The Jeep did not do this before completing the 68C recall. The safety issue is erratic RPM and engine surges. The battery will have plenty of charge and should not need to jump back to hybrid mode. It did not do this before the 68C recall update. My car has not lost 'full' power but I've heard of others that have lost full power or have had major dead spots during acceleration. I have noticed reduced power and loss of acceleration (also a safety issue), as well. My theory is the battery and maybe the hybrid system is faulty. The battery used in the 4XE has been confirmed to have fire risk issues and the 68C seems to have changed the driving function by software update to keep it from over heating but they have created new safety issues with this patch and did not actually correct the original problem (only hide it). Not to mention, the Jeep does not function as originally sold from a powertrain standpoint. My EV battery was replaced after 68C recall but my 'new' battery has the same chemistry and cells so it still has the same fire risk as before but now with the powertrain problem meant to keep to battery cool to hide the fact that nothing was actually corrected (beyond creating new safety issues). If Jeep says that this is functioning as intended that is not correct. This car did not do this before the 68C updates and they have created new problems. Not to mention, possible engine problems resulting with this behavior.

The contact owns a 2021 Jeep Wrangler. The contact stated that while driving at various speeds, the vehicle experienced a loss of power steering assist, causing a more difficult steering effort. The vehicle was restarted to correct the failure. The vehicle was taken to the dealer, who replaced the CAN bus connector, but the failure persisted. While driving 70 MPH, the steering wheel seized and the vehicle almost crashed into a guardrail. The contact sustained body soreness. The contact later received notification of the federal safety agency Campaign Number: 26V363000 (Steering). The vehicle was towed to the second dealer, Nielsen Dodge Chrysler Jeep Ram of East Hanover (175 NJ-10, East Hanover, NJ 07936), who informed the contact that the electric hydraulic power steering pump needed to be replaced; however, the dealer refused to perform the recall repair and stated that the failure was not related to the recall. The manufacturer was made aware of the failure by phone. The failure mileage was approximately 60,000.

2021 Jeep Wrangler 4xe Sahara, VIN [XXX]. 1. The exact malfunctioning component is UNKNOWN; I suspect the hybrid propulsion system. The vehicle is available for inspection. After recall 68C was completed, accelerator response, electric-power availability, and combined gasoline/electric performance changed substantially. The Jeep hesitates when I press the accelerator, the gasoline engine starts at unexpected times, and full electric-mode operation becomes restricted. Combined acceleration is noticeably weaker than before the recall. My complaint concerns restricted propulsion power, not reduced driving range. Horsepower loss has not been independently measured. Whether battery overheating or thermal-protection controls cause these restrictions is UNKNOWN. 2. I regularly pull out into traffic expecting the acceleration the vehicle previously provided, but the Jeep hesitates or fails to gain speed quickly enough. The approaching driver behind me then has to slow down. This recurring delayed response and reduced acceleration make safe gaps harder to judge and create a risk of a rear-end collision. 3. No dealer or independent service center has reproduced or confirmed these post-recall problems. 4. Recall 68C was completed, but these subsequent drivability problems have not been inspected by the manufacturer, police, insurance representatives, or others. 5. I first noticed these symptoms on XXX, at 62,000 miles, after recall 68C. They became more pronounced during summer 2026 as warmer weather set in. No warning lamps or messages accompanied these problems. I suspect a connection to the recall work based on the timing, but the exact cause is UNKNOWN. I request that the federal safety agency investigate whether the 68C remedy causes or leaves unresolved restricted propulsion power and delayed accelerator response.

I had a 68c recall completed by Jeep and immediately after the recall, I noticed a reduction in power when accelerating, which causes me issues when trying to merge on the freeway and stay with the flow of traffic. This has been an ongoing daily issue. Also, the gas engine kicks on when it should not and loads immediately causing an erratic shifting of the gas engine, which causes the vehicle to lose power when it is needed the most. The recall was designed to supposedly protect the electric battery, but the software update that Jeep implemented has drastically changed the functionality and response timeframe at which the vehicle can respond when accelerating. I have tried to have Jeep address the issue, but they indicated the Jeep is operating as intended. It never operated like this until after this recall update and many other Jeep 4xe owners are reporting similar issues with propulsion and the gas engine loading erratically. Thank you for looking into this safety concern.

This vehicle had a 68c recall (software) that has resulted in a significant change in the vehicle performance that resulted in unexpected power loss during its electric vehicle propulsion system that has nearly resulted in accidents on the road and on the freeway. This never happened before and it happens often now. The Jeep dealership claims there are no known error malfunction codes however there has been a material change in the operating environment and is very unsafe.

When driving my Jeep 4xe hybrid powertrain in "electric" mode, I noticed loss of power at highway speeds, and other times at lower speeds. Pushing on gas pedal doesn't translate to acceleration. Engine kicks on but doesn't have a gear to find. This happens at various speeds, going 25mph up a hill or 55mph on a highway either flat or up a hill.
