I own a 2024 Jeep Wrangler Plug in Hybrid Summit Trim Level. I currentl yhave approx 35k miles on vehicle. There has been a significant safety recall out on my vehicle since XXX. The recall code is A7C and it indicates that a software update over the airways could cause a restart of the system resulting in POWER LOSS. I've checked with the jeep dealer multiple times over the past year for the fix and they have no update. I just called jeep customer care and they have no update and are not offering any sort of remedy. Can you please help us? Thank you for your attention to this matter.

I purchased my 2025 Jeep Wrangler 4XE in December 2024. Shortly after the purchase I was notified of the 68C recall. This recall was associated with the Hybrid System Battery. After the recall and subsequent computer upgraded the performance of the vehicle was noticeably different. There was a significant loss of power and changes in the way the IC engine activated. After the the update the vehicle has noticeable acceleration and responsiveness issues. I feel this presents a safety issue that was not there at the original purchase time. I think Jeep has the responsibility to address these safety issues.

While driving my 2012 Jeep Wrangler Sport, the vehicle experienced a sudden and severe loss of engine power due to a cylinder failure on the left/driver-side cylinder head (cylinder #2). This defect causes the engine to experience persistent cylinder misfires, resulting in severe engine stumbling, hesitation, and a dangerous drop in acceleration capabilities. This creates an immediate safety hazard when attempting to merge onto high-speed highways, pull out into active traffic, or navigate intersections, as the vehicle cannot accelerate predictably to match traffic speeds. Furthermore, the persistent misfire causes unburned fuel to dump into the exhaust system, creating a secondary risk of catalytic converter overheating, damage to the exhaust system, and a potential engine bay fire hazard. This vehicle has only 86,000 original miles. This specific 3.6L Pentastar engine generation is subject to a widely documented manufacturing defect involving premature valve seat and head failure, which manifests as an unpredictable and sudden loss of motive power while the vehicle is in motion.

My 2015 Jeep Wrangler has experienced multiple incidents of sudden, unexpected engine shutdown while driving. Without warning, the engine completely loses power, causing the vehicle to lose propulsion and power steering assistance. The dashboard lights and radio remain operational during these incidents. I must turn the ignition off and restart the vehicle, after which the engine starts immediately and operates normally. The vehicle previously experienced similar problems involving additional electrical malfunctions. The fuel pump was subsequently replaced, and the camshafts and rocker arms have also been replaced. Despite these repairs, the engine has unexpectedly shut off approximately two or three additional times. These incidents occur intermittently and without warning, making them difficult to reproduce during dealership inspections. I am concerned that the vehicle could suddenly lose power in heavy traffic or at highway speeds (as it’s done previously even in the pouring rain), potentially resulting in a serious collision. The underlying cause remains undiagnosed and unresolved.

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.

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.
