The fire started in the front and moved to the back of the vehicle. The engine had been off for about 2 hours and vehicle was sitting in the driveway. My son's car seat, stroller and many other belongings were ruined in the fire. A police report was not filed, but a fire report was.”

“Driving Jeep and engine stop, only had steering no brakes fortunately our speed was less than 10 miles per hr and we were in a parking lot. There is only about 770 miles on vehicle and we’ve owned the Jeep 3 weeks. Our concern is what would of happen if we were in heavy traffic, it was rush hour at the time? The dealer is picking up car tomorrow but that doesn’t fix our concerns!”

NHTSA complaint #11420941, filed 2021-06

“The issue is in starting the vehicle. When I push the start button, the vehicle starts, but the engine continues to turn without stopping and turning over. I then push the start button again to turn off the engine and make another attempt, and then it will start normally. This has happened several times in the last few weeks. Also, sometimes when you push the start button, nothing happens, and the vehicle will not start. It takes a second attempt to start normally”
