While driving my 2021 Jeep Wrangler on the highway, the vehicle displayed a warning indicating a malfunction with the Electronic Throttle Control system. Immediately following the warning, the vehicle experienced a significant loss of acceleration and would not respond normally to accelerator pedal input. The vehicle subsequently began accelerating/surging without my commanding the acceleration. The unintended acceleration was significant enough that I had to apply the brakes to prevent the vehicle from striking traffic ahead of me. This created an extremely dangerous situation because the vehicle's acceleration became unpredictable, alternating between loss of accelerator response and acceleration that I did not command. The vehicle is a 2021 Jeep Wrangler, VIN [XXX]. I am reporting this because I believe the Electronic Throttle Control/powertrain malfunction and resulting unintended acceleration present a serious vehicle safety concern.

Sudden unintended acceleration by model year
What owners say
While pulling into parking lot jeep suddenly accelerated deployed brakes it would not stop. Hit pillar in front of store. Did considerable damage to build and vehicle.
My 20214XE Hybrid from the day I bought it was often saying "electric not available" There was a potential fire recall last winter that took four months to remedy, during that time we were told not to charge it, park in our garage, park near our home/structures or park by other cars. I purchase a hybrid that I'm not able to use as a hybrid. Finally, got the repair in the spring. Literally, two months later, it starts doing all kinds of dangerous things. I would come to a stop or be in the middle of a turn and would have no power whatsoever, gas pedal to the floor and going nowhere and then would lunge forward. Took to the dealer, computer said CRITICAL hybrid battery overheating, the original repair clearly didn't work. Eventually, it was approved for hybrid battery being replaced. All was well until 2 weeks ago when it got "jeep death wobble", violently shaking back and forth at about 60mph. They did repair it but informed us that there is ANOTHER RISK FOR FIRE RECALL, do not charge it or park in garage, etc. etc. I have a vehicle that is a risk for BURNING MY HOUSE DOWN, this is multiple times and unacceptable. I also purchased a hybrid that I am not able to use as a hybrid.
The contact owns a 2021 Jeep Wrangler. The contact stated that while pulling into the parking space, the vehicle suddenly lunged forward crashing into the rear of a parked vehicle which then crashed into the rear of a second parked vehicle. The contact indicated that the vehicle lunged forward while the accelerator pedal was released in order to press the brake pedal. During the incident, no injuries were reported. A police report was taken at the scene. The cause of the failure was not determined. The local dealer and manufacturer was notified of the failure. The failure mileage was 9,000.
Today this morning I parked, put the gear in park and all of a sudden the car ravaged up and jumped forward, causing me to go through a fence and stopped. I had my foot on the break the whole time.
We had just reached highway speed of 70mph and the Jeep began a normal regen cycle. However, the engine revved up on it’s own and the check engine light came on and a message that stated the exhaust filter was 100% full see a servicing dealer. Then without any warning, the Jeep went into limp mode from 70mph-50mph. With no notice, we were thrown forward due to the sudden decrease in speed. This action caused the vehicles behind us to swerve to avoid collision. My adaptive cruise control shut itself off and the electronic throttle control warning light started flashing. My throttle control was weak and unreliable, taking a lot of pedal to respond and then not needing hardly any pedal and would surge forward with sudden speed. It was a very dangerous situation. We continued driving in limp mode as there were no safe locations to stop and we didn’t have any cell service. Both malfunction lights remained on and we drove straight to our dealer. They said the EGR cooler failed and clogged up all of the EGR system with soot and then burned out the catalytic converter. They were able to clear the soot out of the system and cleared the malfunction lights so we could drive it home as they didn't have any loaners to offer us. The service advisor told us if we had another vehicle we should park the Jeep and not drive it until the parts come in. They have no ETA on either the EGR cooler nor the catalytic converter. I have been in contact with the manufacturer and there has been no progress on sourcing parts, I am looking in to pursuing a lemon law claim as this vehicle is not compliant with any emissions standards and if not repaired will injure us and others. It is available for inspection with notice, as it is parked at my house I would prefer advanced notice of any inspectors arrival. The warning lights are no longer on, but it sounds and runs like crap and even if the parts are replaced I will always worry that it will do it again. We could have been killed.
