   I had stopped at a red light and the auto start/stop turned off the car. It would not restart. The fault caused it to stay in Park and could not get out of Park to move vehicle. This not only caused a road hazard but made me and others unsafe. The cause was a enclosed fuse box that made batteries go bad. I feel Jeep should be responsible for this.

   I was driving my car and the car shut off at 30 mph. It completely stopped and the steering wheel locked up. Started flashing start/stop and told me to put it in park. Glad no one got hurt and hope it doesn’t do it again.

   This vehicle has ongoing issues with electrical systems. Any time temperature drops into negative digits the vehicle will drain both batteries to the point the auto is inoperable. Further jump starting the vehicle in a very low battery state is a futile venture. The issue leaves the vehicle and it's occupants stranded in sub-zero conditions.

   Constant problems with starter engaging and not starting vehicle. This form only gave me one option for date; This has happened multiple times. This is a defective part, I went to Dick Scott dealership, tech wrote to check car and did not note defective starter; Wanted me to pay $118 to inspect the jeep. In the warranty jargon, it stated if it was a defective part, it would be replaced. I only have 32000 miles on the vehicle.

    On Two seperate occasions, the message telling me to "Shift into P, and then desired gear." appeared while driving. I shifted into P while parked at an intersection both times and the car died. The second time it happened as I was driving away from Rairdon's Jeep in WA. I made it one street after having my ignition system replaced to the tune of $2,600. Was able to turn the car around and get it back to them. They have had my car for almost a month and state there is no…

    The vehicle does not start each time you attempt to start it. Randomly, with no specific conditions to replicate, you will start the vehicle and the starter will engage, but the vehicle will not start. The push button start will time out, you attempt to start the vehicle again, and it starts. This, from my research, is a known issue with 2016-2020ish Jeeps, with a fault in the Fuel Pump Relay, with the easiest fix to remote start your vehicle each and ever time you start it.…
