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.

I was driving approximately 55 MPH on the highway when my vehicle suddenly lost all acceleration. I received an alert on the dash and a chime - the alert stated "Shift to P to Start" - with no other warnings and no CEL or Check Engine light. Pressing the gas, even to the floor, did nothing. I was forced to brake the car to a stop on the shoulder, shut off the engine, and restart the vehicle. Afterwards, I experienced some slight hesitation which resolved, and then was able to drive the rest of the trip without issues. Having the vehicle lose all power on the highway without warning is a serious safety issue.

Vehicle shuts off (engine) randomly during driving. This is the third occurrence. After waiting a few minutes vehicle is -??fine.-?? Dealership is not able to -??replicate-?? the issue. Serious safety issue. How can I operate my vehicle ethically, when I know it could shut off randomly -?? particularly on a fast moving highway" Dealership says it sees no error codes or issues. My hunch is an issue with the fuel pump? Perhaps a fuel sensor" PLEASE HELP! I am scared to death of driving my vehicle, and I feel I am not being offered the assistance I need. I don-??t want to see anyone get hurt. Thank you. Best, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

It has been observed that the antifreeze and oil are intermixing in the antifreeze reservoir, causing the check engine light to illuminate and the system to register a code of PC304. This particular code is indicative of a cylinder misfire, which can cause the car to stop functioning properly and eventually lead to potential engine damage. To resolve this issue, it is imperative to replace the oil cooler filter adapter and flush the engine. This will ensure that the antifreeze and oil are no longer mixing and the engine is functioning efficiently. Therefore, it is highly recommended to take immediate action and get the necessary repairs done to avoid any further damage to the engine.

The problem was related to Fuel pump malfunction, gas leaking. I was advice by a mechanic not to drive the car if there was a fuel leak. A jeep dealer replaced the fuel pump for a coast, since it was out of warranty 41,600 miles on it, but it is much less than the expected life for that part. I was driving on a Highway and suddenly the car started to stumbling and stopped, no lights or warnings, or messages were on.

Vehicle died suddenly in traffic 2 times. Was able to restart after a short while. Was a serious safety issue as I was at highway speed 1 of the 2 times. Vehicle is now at an independent garage. 40k miles. Not under warranty. Has not been inspected or diagnosed yet. No warning lights or codes showing.

Vehicle lost power and stalled on major highway during rush hour traffic. Would not restart. Due to the amount of traffic and sudden deceleration, vehicle was impaired on a major throughway. No warning lamps appeared and all sensors were within normal range prior to incident. Vehicle was towed to Jeep dealership and confirmed the problem was a defective fuel pump. Simply not acceptable for a relatively new, well-maintained vehicle with only 25,000 miles. Incident could have caused serious bodily harm given the abrupt loss of power and major highway on which the incident occurred.

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. I have been driving for 50 years, and today was the scariest day of my life I thought we were going to die in a pile up. Doug savage

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. However, the vehicle does not generate any warning lights or codes when it happens. Based on my research, I have found that several other owners of 2021 Jeep Grand Cherokees have reported similar issues, some of which started at the same mileage as mine. I believe that the problem is caused by a faulty valve in the fuel pump assembly that fails to retain pressure after the car sits for a while. I strongly urge you to investigate this issue further and consider issuing a recall for affected vehicles. It is my belief that Jeep/Chrysler/Stellantis has a chronic problem on their hands that may warrant a recall and replacement of fuel pumps across a specific range of Grand Cherokees. Thank you for your attention to this matter.

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).

I started driving through an intersection after sitting, stopped at a traffic light. I stepped on the gas pedal and the car wouldn-??t move. It made a loud reviving noise but wouldn-??t go anywhere for about 15-20 seconds. I put my hazard lights on and sat for a few more seconds and then put it in park, and then back into drive. I was able to pull onto the median of a very busy road. My vehicle was brought to the dealership who said there-??s nothing wrong with it ???"

While driving the vehicle shuts off and you-??re required to stop before you can turn it back on. This has happened twice and the vehicle has less than 1000 miles currently in the shop with no estimated time of repair.

I was driving my new Grand Cherokee with 121 miles on the odometer. As I was moving forward with the vehicle in drive and was attempting to turn around to- re-enter a highway the engine stopped. I immediately put the vehicle in park and attempted to restart the vehicle numerous times with no luck. The vehicle was stuck in park with the wheels turned to the left. The rest of the electronics worked but the the vehicle locked in park it could not be moved. This represents an extreme hazard to the motoring public as if I had gone 10 feet further and the engine stalled I would have been in the middle of a busy highway. This is totally unacceptable engineering by Jeep. Two towing companies attempted to unlock this vehicle from park with no success. Very hazardous and disappointing work by Chrysler.
