Bought Jeep in December 2020. Currently at 8000 miles. In October 2021, the vehicle would not turn off. The push button would go between acc and start but not in the off. Dealership has never seen this and after 8 days, are not able to definitively tell me what the issue is. The assumption has been given that the car is not recognizing that the vehicle is in park. This is an assumption as whatever diagnosis that is being done is not finding the error.
Updating NHTSA id number 11382705, 10/22/20. Dealer diagnosed issue on 9/15/21 and it was caused by a defective battery. Battery was replaced and there has been no further issue. Please remove or supplement no. 11382705.
Jeep caught fire while parked. Origin of cause states right side of engine is fire origination.
Vehicle in motion city & highway. The entire vehicle dies. The engine turns off, all the lights die, no steering, dashboard & radio die. A few seconds later the engine restarts on its own, lights come on, dashboard lights up and radio works. The one remaining issue that indicates the problem is that the radio complete resets to what I believe is the original settings. This problem has been ongoing since the vehicle was acquired. It has been in the dealerships multiple times and they of course can not duplicate so they send me on my way. They have held the Jeep to drive but claim they cannot duplicate. Also there are no codes showing when they check. Try driving at 65 mph with a dead car. Again this has been happening for about a year.
After only 350 miles my engine started sputtering and had to pull over. By the time we stopped the car the sputtering was violently shaking the vehicle. We had to get it towed only for the dealer ship to take several hours to replace a spark plug. - at almost all time there the air conditioner never seems to get to the desired temperature for more than 20 seconds. When at a stop, the a/c is non existence and temps drop significantly. Unless you have it set to max a/c it will never feel cold/hot. - the transmission is extremely rough at all times, it can jerk you back and forth while it switches gear.
With my foot completely off the accelerator, the vehicle spontaneously accelerates under certain conditions. While in standard or sport mode, in second gear going about 20mph, there is a reproducible rpm surge that causes the vehicle to lunge forward. This somewhat feels like being rear ended.
When using the rear park assist, with my foot completely off the accelerator, the vehicle has spontaneously accelerated while going in reverse, requiring me to hard break to avoid collision. This has happened multiple times.
On September 15–16, 2025, my vehicle was serviced at autonation cdjr north columbus, where the technician documented: “oil filter housing failed internally. ” •no repair, replacement, or warning was provided to me about the risk of catastrophic engine failure. •I was not presented a signed repair decline form. •internal failure was documented but not escalated. On February 13, 2026, the engine failed completely, rendering the vehicle inoperable. The dealership quoted ~$13,094. 83 for engine replacement but did not authorize repair. During this time, oil and coolant leaks were observed, indicating continued mechanical risk and potential safety hazards.
I bought the vehicle Dec 29, 2024 and it had 79000 miles on it. I use it for work , that is driving to and from my job and to the bank and back for work. I would say that in March of 2025 I went to the bank and I got in to leave and put the vehicle into reverse and it would not go into reverse and a the engine light came on. I had to shut the vehicle off and wait 5 minutes and then try again to go into reverse. When I put it into reverse the r was flashing on the shifter and it said something about needing something to be serviced. So when I looked it up it said that was a sign the transmission was failing. I drove it a couple more times and it only happened 3 times total when it was unable to shift going forward. So I took it to a shop and was informed that the transmission was needing to be replaced. There is no reason the transmission should be going out of it. I live 5 miles from where I work and 15 miles from the bank. I dont abuse my vehicles so what is there an issue with the transmission.
