2023 Jeep Grand Wagoneer

The contact owns a 2023 Jeep Grand Wagoneer. The contact stated that while his wife was driving approximately 65 MPH on the highway, the vehicle lost motive power and shut off. The vehicle was later towed to the local dealer, who diagnosed that the thermostat had failed, causing the engine to overheat. The contact was informed that the valve inside the thermostat had bound, causing improper internal operation of the thermostat. The thermostat was replaced, and the vehicle was repaired. The contact was informed that per TSB: 09-006-25, the same style thermostat was installed to repair the vehicle. The manufacturer was notified of the failure. The failure mileage was 17,500.

While driving my 2023 Grand Wagoneer the Serv 4WD light and dash spelled out Service four wheel drive, it lit up the anti collision light, ECS, TCS, and HOLD!. The parking brake also engaged automatically while driving at least 4 times. This is a serious safety concern to allow a vehicle to continue driving with the ability to automatically engage the parking brake while driving. The safety of my entire family was put at risk. I currently have the vehicle sitting at the dealership to be diagnosed and reproduced as the vehicle lost all power after this incident. Another serious safety concern is the total loss of power with no notice. This could easily have been while I was driving and caused a serious accident and possible fatalities.

On Sunday, February 2nd we were driving down the highway when the front sunroof on my Wagoneer spontaneously exploded. Thankfully I had the shade closed, so it caught the broken glass. Had it been open, who knows what would've happened. There were no other cars around, no overpass...just us on the highway. The dealer has the vehicle now, but it doesn't sound like it will be covered under our warranty. However, when I google "my wagoneer sunroof exploded," there are tons of results of people having the same experience.

We the dealership technician had the vehicle for a repair, he was driving it back-and-forth to work like he owned the car and one day He was leaving his home to go to work and the suspension failed so that had to be fixed and that was back on one of the many time it was in the shop. The stop/start engine doesn’t engage for me when I break for me. For me to get it to engage I have to slam on the break as if I was bracing for an accident and then the stop/star engine mode will engage. I think this vehicle has had five clusters replaced in the car, due to the parking sensors, side warning sensors not working. I believe the fifth one went in Dec 2024 once again. The vehicle was in the shop from November 22, 2024 until yesterday DecemberI 2, 2024 when I picked it up. I got home and the parking sensors didn’t beep off and I could’ve crashed it into my garage door and I went through the system and it was already selected to beep but didn’t, then I started getting a message saying that the side warning sensors are unavailable. I put it in reverse it tells me the wipers are off, so maybe all the clusters that they’re making are faulty. The Jeep Retention Customer Service even sent a specialist, technician assistant to the dealership twice or three times to deal with this issue and it’s still not fixed. The dealership Service Center has put in request for answers of how to fix these problems and have had to wait weeks for answers because they don’t know the answers of how to fix the problems with these vehicles and they send a specialist and still the problems still occur they say put in a new cluster a new cluster gets put in the problem still happens. The part is shipped directly from a manufacturer and they have no ETA on that part and my car would still be in the shop, but the Jeep Retention Customer Service Rep had it expedited but the problem is still ongoing. THERE NEEDS TO BE A RECALL ON THIS CAR AND PEOPLE SHOULD GET THEIR MONEY BACK
