    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. This is a serious safety issue, especially since: There was no prior warning Vehicle failure occurred in heavy traffic Driver was stranded in a live lane The issue appears related to core electrical/fuel systems I have identified over 20 similar complaints from Jeep owners of their cars also shutting down in traffic, often without warning. These have been shared on owner forums and consumer boards. I believe this indicates there is a wider pattern that may indicate a safety defect.

    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.

    The vehicle (2021 Jeep Grand Cherokee) was on the road for about 90 minutes when the engine shut off for no reason at 65 mph in noon rush hour traffic. We were in the left lane and had to coast through 2 lanes of traffic and an exit approach while trying to avoid a deadly crash with high-speed traffic. There were no warning lights or alarms on in the car. The only message was that we needed to put the car in park to restart. We finally came to stop and waited a minute and restarted the engine and were able to make it home. I called the dealer, and the next appointment was 3 weeks out. I tried driving during a rainy day before the dealer appointment and the vehicle shut off 3 times in 3 blocks, so I returned home and waited for the appointment date. As of today, the dealer says there are no codes and in 2 test rides the car is running just fine. This is a huge safety issue and I hope that we can get help before anything happens again.

    Service shifter message keeps showing every-time I turn on the vehicle. Eventually it just stays on. Took vehicle in for service and when dealer was installing new shifter, it shorted out other components. Jeep still hasn’t found a permanent fix.
