Vehicle: 2021 Jeep Grand Cherokee Overland, 3.6L V6 Incident Date: [XXX] Location: [XXX] Safety Complaint: On [XXX], while driving my 2021 Jeep Grand Cherokee Overland on [XXX], the vehicle suddenly lost accelerator response while traveling on the highway. The engine initially remained running, but pressing the accelerator pedal produced no response. Multiple warning indicators illuminated simultaneously, including the electronic throttle control, ABS, traction control, airbag, and four-wheel-drive systems. The vehicle also exhibited unusual electrical behavior, including unexpected activation of the high-beam headlights. The vehicle subsequently became completely inoperable and would no longer crank or start. The sudden loss of propulsion while traveling in highway traffic created a serious safety hazard and placed me at risk of a collision. This incident follows an extensive history of significant mechanical failures and repairs to this vehicle, including: Replacement of the cylinder head following repeated overheating and engine misfires. Complete transmission replacement following transmission-related failures. Replacement of the radiator and cooling fan assembly TWICE within approximately one year, most recently during a trip to North Carolina. Additional mechanical concerns, including a camshaft-related diagnostic trouble code. Despite these major component replacements, the vehicle continues to experience serious reliability and operational failures. These repeated problems have occurred despite attempts to address them through dealership repairs and manufacturer warranty assistance. Stellantis previously extended the vehicle's warranty as a goodwill gesture following earlier issues. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Transmission failure at 19,481 miles in my 2021Jeep Grand Cherokee Limited 4x4 V6. The vehicle has not been abused, and the mileage is low for its age. The symptoms—erratic shifting, limp mode, and “Service Transmission” warnings— are consistent with a known defect pattern affecting multiple FCA vehicles using the same transmission.

I drove my car out of my garage on the way to work and just outside my house, the transmission bucked when shifting from 3rd to 4th gear and the p0733 code appeared. I turned around and went home and took another car to work. I had previously taken my jeep with ~85,000 miles to my local dealer wanting the 4 wheel drive and transmission service as I do with all of my cars. It was driving fine, but seemed like the gas mileage was decreasing a bit which I shrugged off. The dealer informed me that the transmission wasn't serviceable. I thought this was odd, but they did the 4 wheel drive service and said everything was good. When I got the error code, I called my local independent transmission shop who said they could look at it in 2 days, so I didin't drive it until the ~10 minute drive to drop it off. They called the next day and said the transmission was done- burnt fluid and bits of clutch in the fluid. They couldn't even find a rebuilt trasmission because according to them so many are failing. They quoted me $8700 for a new transmission from Jeep which I begrudgingly agreed to because what else could I do? I've had one car's transmission fail (Jeep Wrangler but it had 220,000 miles and was 15 years old so I could accept it. The shop received the new transmission from Jeep and then called me saying the valve body was bad, it would not communicate with the car. They went through warranty struggles with Jeep who after another week finally sent another valve body, which also did not work. Finally, they figured out they were sending unprogrammed valve bodies with the transmission and the car needed to be towed to the dealer to program...more $$$. So, after a3+ weeks I finally got my car back today. I've looked online and wondered what I could have done- there are so many similar examples out there of similar experiences, Wrangler transmissions failing with low miles; it's unforgivable that Jeep says the transmission can't be serviced!
