2021 Jeep Grand Cherokee Fuel System Problems

Your fuel pump is losing prime due to a crack in the housing or an internal hose inside the fuel tank. This causes long cranking times before the engine starts, stalling at red lights, and rough idling when accelerating. An independent service center has confirmed and reproduced this issue. The fix will likely involve inspecting the fuel pump assembly and replacing the cracked component or fuel pump unit.

Your 2021 Jeep Grand Cherokee may have trouble starting and require multiple restart attempts, which can wear out your starter and battery over time. The owner reports that Chrysler and Stellantis did not acknowledge a fuel pump relay recall related to this issue, resulting in costly repairs and trade-in value loss. The problem appears to stem from a faulty fuel pump relay that prevents the engine from starting normally. A diagnostic check and fuel pump relay replacement may be needed to resolve the starting issue.

Your Jeep is hesitating when you try to start it. This means the engine may take longer than normal to turn over or may struggle to catch when you turn the key. The issue could be related to fuel delivery or ignition components not working smoothly together.

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.

Jeep's engine turned off while driving, was able to coast and use the brakes to come to a full stop. The engine turned off while driving in a tunnel in the mountains; it was very unsafe. There was no shoulder to pull off to, no extra space to walk around the car, with only 1 other lane available for all the backed-up traffic behind me; CDOT had to tow me out of the tunnel, where I then had to wait on the side of the highway for AAA. There were no warning signs, lights or messages prior to the failure. Had to be towed to the Jeep dealership, where the fuel pump was replaced. There have been recalls on this part for other Jeeps, but my VIN did not show that this was a recall for this specific yr /model.

The fuel pump and then in turn, the auxiliary pump failed. The car would keep turning over a lot before it started. The engine would stop in the middle of travel. This put us in risk as we travelled down the freeway. We took it to the dealership for inspection, and they found a defective fuel pump. There were no warning lights, messages when this occurred.

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.

I bought the Jeep Grand Cherokee Limited in 2021. Since I bought it I have had one problem after another with this SUV. This is the list of repairs on my car since 2021... and Jeep has done nothing to compensate for my troubles. I feel like I got a lemon of a car and I would never purchase another jeep again. We have maintained the car and have records of all oil changes and tire rotation and all necessary maintance that should have been done on the car. July 31 2024... evaporator core fixed car leaking all over AC fixed... jeep couldn't find problem then finally did. Oct. 4 2024.. new radiator... car leaking all over... once again hard time finding problem March 26, 2024... two new batteries installed car hard time starting... was not problem cause March 27, 2024.. same problem brought back and now I need a fuel pump ( car had burning smell and I was driving it because they could not diagnose the problem )and because they made we wait a week to get it checked out they said there could be more damage to car not sure. Fuel pump should last 100,000 miles.. my car has 68, 000.00 In the three and half years with this car I have had one safety problem after another and I am upset I travel to help my elderly parents on Long Island and each time I am afraid something is going to go wrong with this car. I am so very upset on how the performance of a three year old car is running. I feel people need to know that Jeep is not a reliable brand of car. I am so upset and feel that my car is not reliable and safe for driving long distances and short distances. Thank you for listening to my story. I appreciate you letting others now how my experience with Jeep has been. Thank you

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. Two weeks outside the warranty and I am out an extra 2000.00, because unless your car is dead, or it is a recall the jeep dealership always sends the car back saying they can not find anything wrong, extremely dangerous situation to be put in, I am just grateful I was not on the highway when it happened the second time.

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.

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.

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 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.

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).

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.
