2021 JEEP GRAND CHEROKEE Complaints

The vehicle does not start each time you attempt to start it. Randomly, with no specific conditions to replicate, you will start the vehicle and the starter will engage, but the vehicle will not start. The push button start will time out, you attempt to start the vehicle again, and it starts. This, from my research, is a known issue with 2016-2020ish Jeeps, with a fault in the Fuel Pump Relay, with the easiest fix to remote start your vehicle each and ever time you start it. This happens several times per week. I contacted the dealership we purchased the vehicle from, and our local Jeep service department. They were familiar with this issue, acknowledged its a pretty big problem, but because it is not a recall for Jeeps, there is nothing they can do except for me to bring it in and pay for all of the fixes for a known production issue.

Known common problem with 2021 Jeep Grand Cherokees, fuel pump issues. Vehicle fails to start when push button is pressed. After several attempts vehicle will start. These issue happens hundreds of times per year. Vehicle will stall while driving intermittently. Manufacture and NHTSA is well aware if this issue, as it has been documented hundreds and likley thousands of times by dealer ships across the US.

When the cruise control is activated and the set(+) button to accelerate the car continues to accelerate after the button is released. The vehicle will accelerate to 100mph or higher. I have to deactivate the cruise control to get it to stop accelerating. The vehicle is available for inspection. +Unsafe to use cruise control for fear of excessive speed.

My 2021 Jeep Grand Cherokee will not start / turn over and if it did the car will shut off. This has been happening for the past week or so. I took it to my local Jeep dealership today and they are stating that both the fuel pump and the water pump need to be replaced. They also stated that the fuel pump recall does not apply to my vin. In addition to my fuel pump needing to be replaced, my water pump has failed too. It is severely leaking water. My Jeep is only 4 years old with barely 70,000 mi and is experiencing severe safety issues. I cannot drive it as it could shut down unexpectedly while I am driving thereby posing a major safety risk.

The contact owns a 2021 Jeep Grand Cherokee. The contact stated that upon starting the vehicle, the messages "No Seat Belt", "Service Air Bags", "Service Seat Belts" and "Auto Park Disabled" were displayed. The contact stated that the failure had occurred with the driver and the front passenger's side seat occupant wearing their seat belts. Additionally, the brake and the check engine warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the Occupant Restraint Controller (ORC) had failed, and the loss of communication with the ORC had caused the electrical failures.

The manufacturer was not notified of the failure. The failure mileage was approximately 101,000.

I believe it is something with the engine or an electrical component. I was driving and as I was parking my car shut off, was not able to completely park back end of the car is sticking out. I looked up if there were any current recalls using my VIN and nothing appeared. I did my own researching and found that there have been recalls for that model regarding the PTU, Power Steering and Power Loss which is the issue I am experiencing. My car turns off on its own and does not get any type of power. Started having trouble turning on my car over Labor Day weekend was not able to travel due to what I thought was my battery having issues, people were jumping me to be able to start my car. I then had my battery tested at O'Reilly's on 9/3/2025 and when trying to jump start my car they shorted my engine block fuse which I was told after having my car towed to the mechanic and they took a look at it. I replaced my main battery thinking that would solve the issue and it did not and this was before the mechanic looked at it. I then had it towed to a mechanic where they replaced the engine block fuse and I was told that the car was good and running after paying on 9/19/2025. I left the mechanic and came to work where after two hours I tried to start my car and it did not. I called the mechanic and was told it was my auxiliary battery after they came to look at the car and inspect it once again that same day 9/19/2025. I purchased and replaced the auxiliary battery and was able to start and drive the car for 1.6 miles to my brothers apartment from my work before the car turned off on me as I was trying to park. There was an error message on the car at the time when it turned off which read with a caution symbol, "Stop Safely Vehicle Will Shut Off Soon" and then turned off.
