On September 20, 2026 I came outside to find the charging port on my 2021 Jeep Wrangler 4xe smoking and extremely hot to touch. It had been plugged into a level 1 (120v) charging cable to charge overnight outside our garage. I immediately unplugged the charging cable and placed it on the ground. While inspecting the charging port on my Jeep I found the pins charred and melted plastic inside the port, possibly caused from electrical arcing. I made an appointment with the dealership the following day but had to wait until October 26 to be seen. During the appt on Oct 26 they completed software updates and confirmed the charging port had been destroyed and complete replacement was necessary due to the severe high voltage thermal incident. They quoted $1055 for replacement, denying warranty coverage due to mileage (137,000 miles). I believe this malfunction represents a severe malfunctioning defect in the high voltage charging infrastructure of my Jeep 4xe vehicle that put my vehicle, home, and family at risk.

Vehicle shuts down and looses all power and battery controls without warning. My [XXX] daughter was driving the jeep when this happened. Was unable to get vehicle into N for over an hour. Fuses and relays inside the under hood fuse block were extremely hot. After finally getting it into N, we removed from the travel lanes of the 4 lane highway.

After the Jeep 68C recall fix since January 2026: • Aggressive Battery Throttling & "Bogging": The updated software heavily restricts power output (often capping electric draw around 40–50%) to keep the battery cool. This causes a sudden loss of acceleration or a "bogging" sensation. The loss of motive power is a severe safety issue that did not exist before the software update. • Violent Engine Surges: When the electric motor loses power, the gasoline engine suddenly kicks in with a noticeable delay, lurching or surging. • Unreliable Electric Mode: Vehicles frequently drop out of full-electric mode—even with high battery charge—or struggle to maintain highway speeds on slight inclines. In warmer weather, lower temperature thresholds force the gas engine on after only 5 to 10 miles. Constance on and off operation of the engine in electric mode. The engine turns on only a few seconds, then turns off. This cycle will repeat till the battery is fully depleted. Jeep has NOT acknowledged the problem or given dealership guidance how to resolve the issue with the 68C software update.

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.

Since the 68C recall, my 2021 Jeep Wrangler 4xe has not behaved normally and has become increasingly unpredictable. Even with a mostly or nearly full battery, it frequently will not operate in pure electric mode at lower speeds, particularly on even slight inclines. The gas engine can suddenly start when I am expecting electric operation, sometimes accompanied by hesitation, lurching, or an abrupt change in power delivery. I have genuine safety concerns with the vehicle because I cannot reliably predict how it will respond to accelerator input. There have been instances of reduced or delayed power followed by sudden engagement, which is especially concerning when pulling into traffic, crossing an intersection, merging, or maneuvering on a hill. These problems began following the 68C recall, and the vehicle's current behavior does not feel normal, consistent, or safe.

When using electric mode, repeatedly and consistently, when I try to accelerate (for example to get onto a highway) despite having the acceleration fully depressed, the car does not accelerate. After some time, the gas powered engine will rev, the RPM will shoot up and then the car will start to accelerate. If I slow down the electric engine will take back over, but then if I try to accelerate again the same thing will occur. I have videos of the dashboard confirming electric mode, delay to accelerate and eventual activation of the gas motor and RPMs. This same issue was noted by Jeep technicians after the fix for a previous recall on the battery. This is dangerous, If I am not able to accelerate I can not safely drive change lanes, go onto highways, or avoid danger. it has been occurring, but my first video is from Feb 2026, and most recently July 2026.
