Mileage when the problem started

Owner reports

Selected complaints filed with NHTSA by 2021 Jeep Grand Cherokee owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2021 Jeep Grand Cherokee. The contact stated that after refueling the vehicle, the vehicle failed to restart immediately. The vehicle was able to restart after several attempts. The vehicle was taken to the dealer, where it was determined that the fuel pump needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 30,000.

The car keeps dying while I'm driving and saying "shift to park" and then slamming on the brakes and dying. The card is 4 years old with 44k miles. I had to sit on the side of the road in 93 degree heat in Florida while pregnant and waiting on a tow truck. How has someone not died because of this? I've seen SEVERAL posts of people saying the same thing happened to theirs. It's SO unsafe.

I am writing to file a complaint regarding the long start or failure to start issue with my 2021 Jeep Grand Cherokee Laredo. This problem began occurring at around 17,000 miles of use and has happened sporadically but with increasing frequency ever since. When I push the Start button, the vehicle may crank continuously until it times out or sputters to life right at the end of the timeout. This problem can be demonstrated repeatedly by parking the vehicle out in the sun for a few hours and then attempting to start it. I am concerned about the safety risks that this issue presents. The failure to start or long start could put me and others in danger if the vehicle stalls while driving or if I am unable to start it in an emergency situation. I have taken my vehicle to a Jeep dealer, and they have confirmed that they have experienced the same problem. …

On May 17, 2025, my vehicle suddenly shut down in heavy traffic on a major NYC highway (no shoulder), creating a hazardous situation. There was no warning or alert before the engine shut off completely. I was unable to restart the car, and the gear shifter was locked. The brake pedal also became unresponsive temporarily. After some time, the brake unlocked, but the ignition remained inactive and the vehicle was immobilized. The car had to be removed by emergency tow and later diagnosed by a Jeep dealer. The root cause was determined to be failure of the fuel pump(s). Additionally, a blown fuse in the Power Distribution Center (PDC) was discovered. The dealer replaced both fuel pumps under warranty. Jeep has refused to acknowledge this as a safety issue or reimburse emergency expenses despite full documentation. …

I have a 2021 Jeep Grand Cherokee that has 8506 miles on it, I am the original owner. 7 months ago I was in the neighborhood, and it started hesitating, and the engine stopped, no warning lights nothing, after waiting I started it back up and drove home, and it has been fine until last Saturday. Saturday we were at a busy red light in the turn lane, light turned green I turned, car shut off no warning lights nothing. I was stuck in the middle of traffic and could not move the car. The jeep was towed to the shop, premature fuel pump failure. My problem with this is it could have gotten me killed or my children. …

While driving at highway speed the motor shut down without any warning. I was in the center lane of traffic and had no acceleration, no power steering, nothing the vehicle went dead in highway traffic at highway speeds. I had to coast and get over several lanes and on to the shoulder. Vehicle came to a stop on a narrow shoulder with speeding vehicles and 18 wheelers whizzing by. I had to cal 911 and get police to help so I wouldn't get rear ended. Had to wait on shoulder for an hour to get a tow to safety. The vehicle never restarted, and the transmission was locked in park. The vehicle is now at the jeep dealership to see what happened. I just read on line that Jeep Grand Cherokees have this problem and Jeep is not doing anything to repair. Please advise me on how to proceed with this. …

While driving, the vehicle experienced a sudden, unexpected engine stall and complete loss of propulsion due to a premature failure of the in-tank electric fuel pump. This failure occurred at only 37,000 miles, which is well below the expected lifespan of a major fuel system component. A sudden loss of engine power while operating at speed poses an immediate safety hazard, increasing the risk of a rear-end collision or leaving the vehicle stranded in active traffic. The fuel pump had to be replaced immediately to restore the vehicle to a safe operating condition. The original failed component was replaced by an independent repair facility, and all itemized repair orders and proof-of-payment receipts have been retained. I am logging this complaint to urge NHTSA to investigate a potential manufacturing defect in 2021 Jeep Grand Cherokee fuel delivery systems.

Traveling in my Jeep Grand Cherokee L 2021 with family from the Dallas-Fort Worth area to San Marcos along 130 outside of Austin and fuel pump went out (this was recently diagnosed via phone by a Jeep mechanic at Covert Jeep in Austin 4/3/23) causing engine to fail at 85 miles an hour with no warning. Forcing me to navigate through traffic and attempt to get to the shoulder with cars, trucks, and 18 wheelers traveling upwards of 85 miles an hour. Also, was told the fuel pump for my vehicle was on back order with about 150 people waiting for this part (leading me to think a recall should be issued to have this part looked at). Secondly, as I was waiting the woman in front of me asked if it was my fuel pump and that her went out on the Jeep of the same body style. I replied I wasn't sure, because at the time I wasn't sure (Friday 3/31/23).

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.

Driving down an interstate at 70 mph, suddenly the car hesitated a couple of times and the engine stopped. I coasted to the side of the road. No warning lights. I am now sitting on the side of an interstate with 18 wheelers flying by and I am miles away from a town. Two and a half hours later we were towed to a jeep dealer. They performed a diagnostic with results being failure of fuel pump and wiring (intelligent power ipac). Dealership made repairs. I feel our safety was at risk because there was 1. No warning/ 2. Possibility of being unable to get off the road in this situation/ 3. Sitting on a busy interstate, waiting for help. In checking online I found more people complaining about the same thing happening to them, so I feel this is not an isolated incident.
