The Jeep caught fire underneath while I was driving on the highway. There were no warning lamps or symptoms of the problem prior to failure. I saw flames come up over the front of the car and immediately parked and ran with my child. We could have died.The fire and stopped car in the middle of the highway could have caused a pile up of crashes. It is unknown what component or system failed and I don't believe it is available for inspection as State Farm decided not to move forward with inspection. They declared it a total loss.

The vehicle was sold by DriveTime (Highland, Indiana) on August 29, 2025, with a known safety recall (Y18 - Transmission Oil Cooler Hose, NHTSA 21V-310) that had not been properly repaired. Jeep dealership documentation dated October 17, 2025, shows the recall was only "inspected" but no repair was completed. Within 30 days of purchase, the check engine light began turning on and off intermittently, and an AutoZone diagnostic (Code P0934 - Hydraulic Pressure Sensor Circuit Low) confirmed a powertrain failure related to the transmission system. The defect affects hydraulic pressure and gear shifting, creating an unsafe driving condition that risks transmission failure while in motion. The issue has been confirmed by both AutoZone and the Jeep dealership but not repaired. Dealer and warranty administrator SilverRock have refused to provide repairs or a loaner vehicle. …
My 2021 Jeep Cherokee Trailhawk has been effectively unusable since April 19, 2026 due to the PTU issue associated with FCA Recall 40D/NHTSA Recall 26V-290. I previously filed a complaint regarding this vehicle. It has now been 5 months with no repair remedy available. Due to being told by the certified dealer, Mopar, Jeep/Stellantis (who closed my claim because they claim the vehicle is safe to drive despite of having an outstanding safety recall) I thought I would attempt to drive the vehicle again. On September 15, 2026, the vehicle lost all motive power while I was traveling approximately 65 mph on the highway on my daily commute. I had to coast the vehicle to the shoulder. This is the exact type of safety hazard described in the recall. FCA/Stellantis has not provided a repair solution, rental vehicle, reimbursement, or other meaningful transportation assistance. …
There are times I go to start my car and it has nothing. No lights no door dinging nothing. I started it up on day to go to work and got to the gas station and shut it down to run in quick. Came out 5 mins later and it acted as if someone took my battery out. The car was totally dead. After about 10-15 mins it lit back up and was able to start. Another time it happened in the dead of winter and I was picking my son up. We went to get in the car and all 4 doors were opened. No lights came on and wouldn't start and as my kids shut doors it would flicker. Times it comes back to life and as soon as you hit the start button it goes black again. It's been at Tristar and c Harper both and cannot replicate so no fix. I'm afraid it's going to catch fire or something one day. In the shops for a month and a half total and no results. It's very intermittent so does not do it all the time. …
I bought my 2021 jeep in 2023 at Matthew's in Pa and from day 1 my antifreeze has been leaking, I Bought the extended Warranty and they told me I didnt buy it and wouldn't fix nothing, so I took it back down there and other guy told me yes I had a Warranty but it's outdated and nothing they can do, which isn't fair on me!

Now I have every light on seat belt, air bag, engine light, parking brake, lane assit, etc and I can't afford to fix it and the inspection is due but can't get it fix all because of them telling me I didn't have a Warranty!!! Please respond my name is [redacted] phone # [redacted]
While I was trying to get onto the interstate my vehicle would not accelerate. I tried to merge in with traffic but I was only going 35 and I almost hit someone. They stayed the same speed hoping I would speed up in front of them but I couldn't. This put everyone around me at risk. I took my vh to the dealership. They called me today and told me they sold the rental I was in and that I needed to bring the car back. Also they ran some codes and my car is coming back fine. So they did not find a problem. I honestly feel they didn't look they just wanted to sell the rental car. I've had no warning lamps at all come on but the transmission is slipping.
