36 Engine And Engine Cooling problem

Failure Date: 10/12/2022

Engine mounts have failed. According to the fca, they have a very large backorder on these parts, as this is an extremely common issue. Initially they denied that the motor mounts were an issue; however, since the major back order, they have reversed that claim. They also stated the motor mounts would be at the dealership on the 13th of October; however, they now state that they have no date due to major back order. They stated no recall was issued because it's not a safety hazard; however, according to multiple certified mechanics, this is a major safety hazard which can result in the motor shifting and knocking parts out from under the vehicle, causing pieces to hit the vehicle itself or other vehicles on the highway. It also will cause major damage to the engine and other components under the hood of the vehicle. The fca still has not agreed to this claim, even as some of their own mopar mechanics also stated the same information regarding it being a safety hazard.

2/18/2022, I was driving down bethany and 75 in allen, texas when my vehicle made a sputtering noise then the gears went out. Could not engage the gears to drive or reverse. I coasted the vehicle to the church parking lot where I sat for 6 hours waiting on a tow truck. When tow arrived, vehicle's brake and parking break had to be pushed down to allow vehicle to go into neutral. Vehicle would turn on, but the ac/heating system did not work, radio was shorting out and vehicle remained locked in park. Check engine light came on after the sputtering and did not turn off. Vehicle was serviced the previous week at Dodge city mckinney with no reported issues of this caliber. Per dealership, codes are showing issues with the transmission and engine. Vehicle only has 9347 miles and if I had been on a major highway, I could have been severally injured when the vehicle stopped. Dealership, made no attempt to review the issue upon its arrival.

42 Engine And Engine Cooling problem

Failure Date: 02/18/2022

Last night, my brand new car (Jeep Grand Cherokee l limited) tried to kill me. Driving down 1187 going 40 miles an hour, it came to a dead stop, put itself in park and would not crank or start back up. All I could hear in the panic was screeching tires from cars trying not to hit me. The seatbelt also did not stop me and I was thrown into the steering wheel. My car has less than 900 miles on it. After a panic attack of epic proportions and a sleepless night, I immediately drove it to the dealership today and of course they can find nothing wrong with it. They are going to keep it a few days to double check a few things, but to say I will no longer be able to drive this car without severe anxiety is an understatement. It has less than 1000 miles on it and I haven't even made my first payment. Trading it in, I will automatically lose $3100. If I don't trade it in, I don't think I would ever be able to get over the anxiety of driving it. Talk about a lose/lose situation. All I could think about is if I had been going faster and there had been more traffic, I could have killed someone including myself. Thank you to the kind salesman who, when I pulled up this morning, said "I love your car" and I proceeded to break down crying and hand him the keys and say you can keep it. He was so helpful in calming me and getting it checked out right away. I've owned it 21 days exactly. Honestly I am not sure I want to take the chance of it happening again.
