2021 Jeep Grand Cherokee: sudden loss of power

Filed Jul 14, 2026 · Fuel system · NY

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 the federal safety agency to investigate a potential manufacturing defect in 2021 Jeep Grand Cherokee fuel delivery systems.

This submission is an update to the federal safety agency Complaint #11727024. The vehicle continues to experience recurring engine overheating and misfire conditions. These issues have been previously diagnosed and are consistent with known manufacturer Technical Service Bulletins (TSBs) related to this engine. Despite this: The dealership has not performed the appropriate diagnostic protocol (including STAR testing) The manufacturer, Stellantis, closed my case without resolving the issue No repair or corrective action has been completed The vehicle remains in operation due to lack of manufacturer support. This condition presents a potential safety risk, including: Loss of power while driving Risk of engine failure or shutdown Increased risk during normal roadway operation The vehicle is regularly operated by my 17-year-old daughter, which increases concern regarding driver safety and reliability of the vehicle under these conditions. This situation reflects: A known defect documented by the manufacturer Failure of the dealer network to properly diagnose/repair Closure of a manufacturer case without resolution of a safety-related issue I am requesting that this complaint be reviewed as part of any broader pattern of similar failures and considered for further investigation.

I am reporting a repeated safety-related issue involving my 2021 Jeep Cherokee Overland. The vehicle has experienced ongoing engine misfires and overheating, which create unsafe driving conditions. The issue presents as follows: -Engine begins to misfire, causing rough operation and shaking. -The check engine light flashes intermittently indicating active misfire. -Vehicle performance becomes inconsistent, with concern for loss of power while driving. -Vehicle experiencing coolant loss/overheating, concern for engine failure. These conditions create a serious safety risk, as the vehicle may lose power unexpectedly or become inoperable while driving. Multiple repair attempts have been made, including replacement of ignition components (coils and spark plugs) and other related service. The issue continues to recur, and the root cause has not been resolved. Despite repeated attempts to resolve the issue through the dealership and manufacturer, the problem persists and the vehicle remains unreliable. The manufacturer has not provided a resolution despite multiple attempts, and communication is unsuccessful I am submitting this complaint due to ongoing safety concerns and a lack of resolution.

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.

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 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.

On May 4, 2023, immediately upon starting the car, warning lights were illuminated: Blind Spot Alert Unavailable - Service Required; Stop/Start Unavailable Service Stop/Start System; Service Electronic Stability Control; Oil Change Required; Service Power Steering; Check Engine Light. Vehicle had no power steering. It was taken to the dealership several hours later, and at that time no warning lights came on and the car had power steering. Dealership indicated that there was nothing wrong with the vehicle. On July 1, while driving 75 mph on I-95 in New Hampshire, while on a road trip from NY to Maine, multiple warning lights illuminated and vehicle immediately lost power steering. I was barely able to get it to the shoulder. Not one Jeep dealership in the area was available to see the car. A local mechanic was able to hook it up and determined that the car lost connectivity. He agreed to keep the car while we continued on our trip with a rental car we found and contacted our Jeep dealer. Two days later, while waiting for our Jeep dealership to tow it home, we learned that the vehicle was completely dead and won't even accept a charge to the battery. Chrysler Customer Service was called and a case was opened on July 3rd. Upon calling back on July 5th, I learned that they "closed" the case. No one could explain to me why and I asked for it to be reopened. Called back on July 11th and spoke with a different representative who indicated the case was "closed" and there was no indication of my call from July 5th. Reiterated and clarified all information and now await a call from a Specialist. The car is still not in NY and is still at the mechanic in NH waiting to be picked up by Jeep to be inspected and fixed. My safety and that of my family, and those in the cars around me, were put at risk as a result of this incident as I lost the ability to steer the vehicle while traveling at 75 mph.
