36 Power Train problem

Failure Date: 05/21/2021

This started in may. The rear locker light came on by it self while driving, and at one point, service locker light was also lit up. I wanted to make the appointment but the light went out so I continued driving. In June, it came back on so I made an appointment with the dealer who was not able to get me in. The dealer kept the car for almost 2 weeks, changed a part and sent me home. As I was driving home from the dealership, the light came back on. If the axle is locked at a high speed(which is for off road, low speed only) this could potentially damage the rear axle differential and have catastrophic failure, which could lead to a crash. This issue is occuring at random.

38 Power Train problem

Failure Date: 02/23/2021

Brand new jlur first road trip, got less then 500 miles out of CO into hays,KS. Vehicles has lees then 5000 miles, was passing a vehicle at 68 mph. Lost all forward gears, got a code for valve body silenoid high voltage. Jeepcares did nothing for a tow. It's a little sad you pay $55,000+ for a vehicle, just to have a vehicle sit in the shop with no loaner. Transmission is on a 2 month back order. Word of advice stay away from any the new jl/jt model Jeeps.

39 Power Train problem

Failure Date: 10/25/2020

The autopark sensors, ( park collision warning), in my 2020 Jeep Wrangler randomly triggers and engages autopark. The false triggers randomly occur when the vehicle is in reverse. The condition occurs at very low speed after the brake is touched. The false triggers occur during daylight or night conditions. Once autopark is engaged the vehicle will not move. The engine must be turned off and sometimes the autopark switch must be turned off before the vehicle will move. There is usually no object within 15 feet of my vehicle to trigger the autopark sensors. I videotaped some of the occurrences using my cell phone. The Jeep service department is not able to diagnose the problem. In addition, the false triggers are not creating system log entries to prove the event occurred. Jeep service department will not use my videos as evidence the event happened. Jeep service will not escalate the problem unless their service department can recreate the condition. My video is 200mb, exceeds your upload limits.
