Won't start by model year
What owners say
Frequently, my vehicle would not start. It would crank for a lengthy period of time but the engine would not turn over to start. Internet searches show that this is a widespread, known problem with Chrysler vehicles, yet only a small number of recalls have been issued. Unfortunately, my vehicle does not fall under the recall for unknown reasons. I have been advised that the fuel pump and auxiliary fuel pump need to be replaced, which is a costly repair. A fuel pump should not fail on a vehicle with under 50,000 miles on it.

There are times when I go to start the car and it will not start. It sounds like it is trying but won’t completely turn on. When I press the starter to the off position and then try again it works. We took it to the dealership and they said I need a new Fuel Pump. There is a recall for this but not on my vehicle.
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.
This issue has now happened 3 times. The first time it happened I took it in and they said it was an auxiliary battery that was replaced. The issue is the vehicle will stall and shutoff completely because it is completely out of fuel even though the electronic gauge and the needle show it has gas in it. This Saturday we was driving on the interstate at around 70mph and it showed a little over a 1/4 tank on the needle and 130 miles to empty on the digital readout. It shutoff completely and we were almost hit on the interstate from behind I barely had enough coast to get over to the side of the road. The first time it happened it shutoff and was going much slower and it actually started back up and let me drive. The second time I was siting at the gas station with a little lesss than 1/4 showing on the needle and it shutoff and wouldn't start back until we pushed it to the pump and put gas in it. When this happens it never takes a full tank to fill it back up so there is gas in the vehicle.This is very dangerous.
While trying to start the Jeep with the keyfob in the vehicle the Jeep will not start and I get Keyfob Not Detected error on my dash. Followed by Hold keyfob to start button to start.
I was evacuating the Colorado Marshall Fires and my 2020 Grand Jeep Cherokee with 20,000 miles just quit while driving down the road. It was slow moving traffic out of the area with 100 MPH winds, heavy smoke and debris flying through the air. As I tried to restart it, there was a message about some sensor, but unclear as to what exactly the message was. The engine would not turn over. The car was partially blocking traffic and caught on fire approximately 10 minutes after it stopped. Those evacuating were down to one lane and navigating around a burning car. No investigation is possible as it is completed burned up. I have followed all of the manufacturer's recommended maintenance schedules and have had zero incidents with this Jeep prior to this. I would like some sort of investigation as to the cause (an assessment of the situation as there is no car left to inspect). I do not want this happening to another person/family as they are trying to get out of a dangerous situation. I was lucky in that there were others evacuating, however, had I been in an isolated area, my dogs and I could have been dead.
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.
