Filed Jan 25, 2026 · Engine, Transmission · WI

I purchased this vehicle, November 2023 and by August 2024 the vehicle went into Griffin Hubs to get the engine replaced. They had the vehicle for over a month and a half when I received it back after the engine I had it for a day and a half and had to take it back because it was making a loud grinding noise coming from the engine which then they had to replace a second time because the engine was shredded and was told they were going to put a new transmission in as well, but instead of just replaced a piece, and then two months later, the negative terminal for the battery was replaced in about four months later I take it into the dealership again because as I was driving the vehicle pulled back three times and then shot forward and that happened seven separate times dealership said they could not find an issue and then in November 2025, the vehicle goals back into the dealership for overheating needing a new water pump because I was losing coolant with no leaks. Get the vehicle back two days later my coolant is empty tied again call the dealership they said if it happened again, bring it back in two weeks later it did the exact same thing. My coolant was emptied, but there is no leaks coming from under the vehicle and now last week as I was driving, the vehicle suddenly stopped accelerating and my gearshift wouldn’t catch any gears and as the vehicle is still moving my tires, then locked. The vehicle has been at the dealership for five days and they still cannot figure out what the issue is.

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.

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.

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.

While I was driving down the road the transmission failed and I had to have the vehicle towed and the transmission replaced. The vehicle only had 460 miles total at that time. The vehicle now has 940 total miles and I am beginning to feel hard shifting and slipping while driving, that seems to me that the new transmission they put in the vehicle is going bad already. I will be taking it back to the dealer to have them look at it. I was on a city street going straight at approximately 30mph.
