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.

Stuck in gear or won't shift by model year
What owners say
At approximately 54,000 miles the transmission is not shifting. I parked in a parking spot, go into a store. Then come out and the vehicle will not shift into park or reverse. The check engine light came on for the park by wire issue. These transmissions have been known to have rough shifting and my vehicle has been no exception. It’s shifted rough at low speeds and the eco mode and auto start/stop system have also made it feel less than smooth to drive.
The transmission went out in October 2024 and was replaced in November 2024. Since then, the valve body has been replaced twice and probably needs to be replaced again. The car does not shift into/out of third gear properly or consistently which causes very delayed acceleration. This is a safety hazard when entering the roadway, especially merging onto the highway. Chrysler is aware of the valve body being “bad” yet continues to “replace” with bad parts.
Car wouldn't shift into drive. Git car towed in was told possible cam shaft issues. Car has been back 3 more times for same issue finally Stellantis replaced cam shaft. Now same problems are occurring and Jeep wants me to pay to replace engine on a 4 year old car.
Transmission failure, vehicle will not start and will not shift into reverse, leaving driver stranded and stuck in vulnerable parked position. Check engine light comes on with P1B14-00 code - "Park by wire unintended park position". Engine light did not come on until after issue happened. Dealership diagnosed and confirmed issue and engine warning light code P1B14-00. They re-flashed vehicle ECU due to recall and that did not resolve issue. They are suggesting completely new transmission.
The check engine light started appearing on the dash and the adaptive cruise control kept appearing that it was off. The light would go off and come on again and the transmission would not shift gears and I could not go in reverse. I drove vehicle to Marino Jeep and they notified me of 3 defects in the internal transmission- which I still have my warranty as the car is at 32.800 miles ONLY on the odometer. This was a dangerous defect causing my car to stall.
Transmission failed while driving in traffic. Car decelerated from 45MPH to 0, gas peddle would not accelerate, break was locked in place, steering wheel locked, no warning lights appeared, flashing D on gear shift (was in drive), alert appeared on screen “Shift to P then desired gear”, car would not shift gears and gear shift was locked in place then pressed the Push to Start button, car restarted and then shook and jerked forward before allowing me to switch gears from Drive to Park then back to Drive. I was almost rear-ended by two PickUp trucks and SUV. Trucks behind me swerved out of the way to avoid hitting me and almost drove into an 18-wheeler. This occurred 1/10/2023. Problem first occurred in October 2022 in grocery store parking lot while shifting between Drive and Reverse gear. Same thing happened as stated above.
My Safety as well as other Drivers safety are at risk when you down the highway at a speed between 70 & 75 miles an hour and all off a sudden your engine quits, I was told it goes into limp mode, I turned off engine, started it again could not get power, turn off engine again waited a few minutes and it finally gave me some power, was told by the Dealership that they could not find anything the computer may have reset itself, in a one week period it did twice, I nearly got hit or the person could have got killed hitting me. This is definitely a safety issue I think this should be a recall.
Transmission lost power while driving. Was not able to keep rate of speed. Car stopped and would not go into gear stranded in traffic.
Leased my grand cherokee 2020. Drove the car twice. It wasn't even 24 hrs since I had the car, my car broke down the 2nd time I drove it (on a friday). I was waiting on line for my sons graduation. It was a drive through graduation because of covid-19. I was the 1st on line and had 50 cars behind me. When I was asked to proceed my gear didn't shift. I turned the car off and tried restarting it and it didn't start. Had to get the car towed to a dealer. I was told id have to wait till monday. Called jeep to complain. I asked for a loaner and was told I had to pay for it. I find that insensitive, rude & unprofessional. It hadn't been 24 hrs that I had the car, I only had 88 miles on the car and I was being asked to pay for a loaner for a car that broke down because of a manufacture defect. Im assuming because I filed a complaint with jeep, they pressed the dealer to look at the car asap. I received a call to say I ran out of gas. My gas indicator showed I had a half tank of gas. The fuel sending unit which sends a signal to the gas gauge on the dash, letting you know how much fuel is in your the tank wasn't working. The sending unit is integrated with the tank fuel pump & strainer. So both my fuel pumps need to change. The main fuel pump is on back order and I was told I could be waiting weeks or months for the pump to come in. I was told as long as I gas up my car every 200-250 miles I "should" be fine until the fuel tank comes in. I was very disappointed with jeep customer service. Not only were they unapologetically but they did not try to find a way to accommodate me for a problem that they were responsible for. Sadly I just received this car on a 42 month lease. I have to wait for the car to be fixed and pray that I don't get stuck on the road again or any other problem arise. I wouldn't worry about my 42 month lease if I knew I could rely on their customer service.
