2021 JEEP GRAND CHEROKEE Fuelpropulsion System Problems

The 2021 Jeep grand cherokee I owned had problem when I started the vehicle It would not start and had to do it again and again to restart which damaged the starter and batteries I suffered a big monetary loss when I traded this car as Chrysler and Stellantis refused to acknowledge the recall of the fuel pump relay

THE ISSUE IS IN STARTING THE VEHICLE. WHEN I PUSH THE START BUTTON, THE VEHICLE STARTS, BUT THE ENGINE CONTINUES TO TURN WITHOUT STOPPING AND TURNING OVER. I THEN PUSH THE START BUTTON AGAIN TO TURN OFF THE ENGINE AND MAKE ANOTHER ATTEMPT, AND THEN IT WILL START NORMALLY. THIS HAS HAPPENED SEVERAL TIMES IN THE LAST FEW WEEKS. ALSO, SOMETIMES WHEN YOU PUSH THE START BUTTON, NOTHING HAPPENS, AND THE VEHICLE WILL NOT START. IT TAKES A SECOND ATTEMPT TO START NORMALLY

Engine died twice on busy freeway and needed to be towed to a shop. Shop verified the fuel pump was working. There is most likely a problem with the fuel pump relay.

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...

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.

First gear knocks hard in to gear,this happ en on uphills,cluster and the speed meter and the in infotainment screen has go pitch black,loss of power under acceleration and collapsing all the system of the car.

There is a delay in my car starting when I push the start button. When doing some research online to see what the possible issue might be I found that other cars with the same make/model/year had this issue and was apart of a recall for the fuel pump relay.

My 2021 Jeep Grand Cherokee will not start / turn over and if it did the car will shut off. This has been happening for the past week or so. I took it to my local Jeep dealership today and they are stating that both the fuel pump and the water pump need to be replaced. They also stated that the fuel pump recall does not apply to my vin. In addition to my fuel pump needing to be replaced, my water pump has failed too. It is severely leaking water. My Jeep is only 4 years old with barely 70,000 mi and is experiencing severe safety issues. I cannot drive it as it could shut down unexpectedly while I am driving thereby posing a major safety risk.

Electric start is cranking but engine takes up to 10 seconds or longer to turn over. This happens from cold start and even the stop start when in drive at a stop sign or stop light. It is either an issue with fuel injection/fuel pump or something else as it is not a battery issue just replaced them to be sure or a starter issue.

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.

When starting car, the push to start feature will not turn over and continuously cranks multiple times. The entire fuse box was replaced because the dealer told me that was the issue. The car is a 2021 Jeep Grand Cherokee Laredo. Numerous people online said they were forced to replace the fuel pump? Although Faulkner Buick in Trevose told me that there’s nothing wrong with my fuel pump. I can’t keep getting charged for repairs that are not necessary. Could this be a faulty part? that so many people have the same issue? Could you please investigate this as I just bought the car a month ago And it’s been at the dealer three times already. Thank you.

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...

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 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...

Vehicle quit running while driving was going about 5 miles an hour just shut down tried to restart cranks but will not start no safety issues We had to call a tow truck and have vehicle towed to dealer has about 24,000 miles on it. It sounds like a fuel pump issue. Valley motor city Jeep in Cuyahoga Falls, Ohio, 330-937-9481 where the vehicle is being repaired called me Friday 9/6/24 and said they ordered a fuel pump I talked to Christy, the service writer she said parts will be in next week. does Chrysler have any recalls on this?

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...

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.

This was 5 -6 times my new car broke down 3 times for fuel pump problem then i have engine light on more than4-5 times . Now its still on they fixed it 2 month ago. I just buy this brand new car in 2021. Not completed 3 years yet and having 56700 kms on it .

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...

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...

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...

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.

MY GRAND CHEROKEE HIGH ALTITUDE 2021 START JERKING DURING ACCELERATION AT 500 MILES APROX. THEN THE PROBLEM WAS MORE CONTINUES AND IN PARKING OR NEUTRAL THE CAR START JERKING, VIBRATION ENGINE AND EXHAUST SMELL WEAR. CHECK ENGINE FLASING. CODE P0304 WAS REGISTERED.
