Engine fuel pump Cavitates and dies while at Idle or under power on highway. Fuel leaks out of the fuel tank vent in the Right Aft Fender well over the exhaust pipe. This is an intermitting problem.

When driving about 50 miles per hour on the highway, it felt like my engine suddenly gave out and my dash turned off. When it came back in, there were multiple indicator lights and a message that read "Pull over safely and shift to Park." I did just that, but after that I couldn't get the car to turn back on or shift out of park. I had to have to towed to the dealer and it has been there since 10/13.

I have owned this vehicle since August of 2021 and consider myself very familiar with the normal operation and performance of the vehicles propultion system. From August of 2021 through December of 2025: - I could operate the vehicle at highway speeds in full electric mode - I could reliably tell when the vehicle would transition to the internal combustion engine and how the vehicle would respond when it transitioned (a smooth transition) - I could have confidence in how the vehicle would accelerate when the gas pedal was pushed. I had the 68C recall performed on 12/23/25 and since the recall, the vehicle's propultion system has not been the same to the point where it is a safety concern. - I cannot operate the vehicle at highway speeds in full electric mode and in many cases cannot operate in electric at lower speeds. - When the vehicle transitions to internal combustion, the engine climbs to an unsafe RPM, then reduces RPM in stages until transitioning back to full electric. This process repeates iteslf over and over as if the vehicle is trying to find the right balance between electric and gas. These transitions cause unreliable fluctuations in speed and power and put unecessary strain on the engine. - There are times when I will go to accelerate and nothing will happen for a couple of seconds. This is particularly dangerous at intersections. - There are times when I will go to accelerate and the vehicle will start in electric for a second and then immediately jump to 4500 RPM on the internal combustion engine, jetting the vehicle forward in an unsafe manner. The dealership noted the behavior, but cannot identify any codes and the official message from Jepp is that this is "Normal Operation." I've driven this vehicle for over 5 years and over 60,000 miles. I can confirm that this is not normal, this is not how it always has been, and there has been a change made to the performance of the vehicle since the recall. I have videos of the behavior.

My 2021 Jeep 4XE is not safe after the 68C battery recall, this recall has caused the combustion engine to start intermittently even though I am in hybrid or electric mode, when this happens, the jeep will not respond to the accelerator pedal for a few seconds while the computer figures out what to do, when pulling away from a stop sign or turning left in traffic this lag has made it very difficult to drive in traffic. I feel the 68C recall has made this vehicle unsafe to drive unless you know it's going to lag and make driving corrections because of it. At this point I will not let anyone but myself drive it for fear they will experience the lag and end up in an accident because of it. I have had it back to the dealer 2 times and they acknowledge my complaint but since it has no codes they can't or don't know h0w to fix it. They have contacted Stellantis and they advise the jeep is operating as designed. It didn't do this prior to the 68C recall. Not sure what to do at this point but I now have a vehicle that I bought because I liked the performance of the Hybrid system but now that performance is compromised to the point, I feel it's not safe, and Jeep cant seem to rectify the issue even though the dealer acknowledges its and issue

I purchased my 2021 used with 29k miles in April 2024. Since then I have had to deal with three recalls but one of particular concern- 68c, meant to reduce the incidence of fire caused by the battery cell separators. Since then I have experienced a very noticeable change in how the Jeep drives. There is a large gap in available power, the gas engine sometimes kicks in unexpectedly at high RPM, other times I press the accelerator to the floor with no response, and at times there is a severe lag between the time I need to accelerate and the time that power is available. Overall not only did the recall fundamentally change the vehicle I purchased it also introduced unsafe driving characteristics because it is less predictable in its response.

After application of the most recent battery recall/Software update, 68C, the vehicle operates differently than it previously did. In fact, it now nearly stalls while climbing a hill to my home when the battery charge indicated is less than about 35%. Vehicle speed drops from 25 to nearly 5mph, independent of accelerator pedal position, before the engine starts abruptly. Not only am I creating a traffic hazard for those behind me, but the cold gas engine engages at full load. Secondly, the overall response to accelerator input seems to be much slower, both in time and power, than before the software update. This causes issues when pulling out into traffic and is especially alarming when the Jeep won't respond as it did for the previous 50K miles.

This vehicle has become unsafe to drive and no longer has the performance that it had when originally purchased since the 68C recall. In electric mode, I experience low power and the acceleration is almost non-existent. This has caused significant safety issues when merging onto highways and maintaining flow of traffic speeds on hills. In electric mode, after about 10-15 mins, it will also abruptly start the engine and spike at 4K RPM (even when the vehicle is not under strain or accelerating), then drop to 1K RPM, then spike back up to 4K RPM, then go back down, then up, over and over, causing concern over engine wear and gas mileage impacts. It will not go back into electric mode when this happens until the vehicle is turned off and back on again. We have reported this repeatedly to the dealership, and they have stated that since there are no codes, their hands “are tied”, and there is nothing they can do. I do not want a buy-out or money settlement; I simply want this vehicle to operate the way it did prior to the 68C update.

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

Manufacturer corporate and its dealer network are failing to provide a safe, timely remedy for a vehicle subject to high-voltage battery fire recalls (Recall 68C / the federal safety agency Campaign 25V‑741) and a power steering fire recall (Recall 21D / the federal safety agency Campaign 21V‑363). The vehicle has an active check engine light, a disabled hybrid propulsion system, and has now suffered a catastrophic electronic brake booster failure on a college campus, rendering the brake pedal rock-hard like compressed air and leaving the vehicle unable to stop normally. This is a direct, recurring safety failure of Diagnostic Trouble Code DTC C0580-00 (Brake Booster Motor Circuit Low), which was officially documented by a franchise dealer in June 2026. The vehicle also has an extensive history of severe manufacturing defects, including an extraordinary 72-day out-of-service period at a dealership in Miami, FL for a disintegrated rear axle bearing that destroyed the differential housing, alongside advanced structural body rust on hinges found to be unsafe. The manufacturer was formally notified of this active safety emergency and loss of vehicle utility on Sunday, September 27, via email and corporate phone logs, but failed to respond or secure the vehicle. We are formally demanding an expedited manufacturer repurchase/buyout due to total loss of vehicle utility, structural housing conflicts under 'park outside' directives, and severe physical safety liability.

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.
