I had stopped at a red light and the auto start/stop turned off the car. It would not restart. The fault caused it to stay in Park and could not get out of Park to move vehicle. This not only caused a road hazard but made me and others unsafe. The cause was a enclosed fuse box that made batteries go bad. I feel Jeep should be responsible for this.
This submission is an update to NHTSA 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 was driving my car and the car shut off at 30 mph. It completely stopped and the steering wheel locked up. Started flashing start/stop and told me to put it in park. Glad no one got hurt and hope it doesn’t do it again.
I own a 2021 Jeep Grand Cherokee Trailhawk which we purchased new. On Dec 30, 2025 we were driving home and received a service suspension message on the dash. We took it to our mechanic immediately and they diagnosed it and replaced the left front ride sensor. $380.88 In Jan 21,2026 the ride height message was back. They removed and replaced the air pump assembly with a new united. To remove & replace-suspension-rear suspension-ride control compressor, R&R $2,026.31. Feb 26, 2026 Took back to Lithia Dealership . Stability Control light was on and Traction control light are on check on advise. Changed out Module Transfer Case $1,013.33. Upon further research found out other Jeep owners had the same problem with the air suspension system. I feel this should be looked into.
The screen for mapping other controls is delaminating, creating a safety and distraction hazard
This vehicle has ongoing issues with electrical systems. Any time temperature drops into negative digits the vehicle will drain both batteries to the point the auto is inoperable. Further jump starting the vehicle in a very low battery state is a futile venture. The issue leaves the vehicle and it's occupants stranded in sub-zero conditions.
Constant problems with starter engaging and not starting vehicle. This form only gave me one option for date; This has happened multiple times. This is a defective part, I went to Dick Scott dealership, tech wrote to check car and did not note defective starter; Wanted me to pay $118 to inspect the jeep. In the warranty jargon, it stated if it was a defective part, it would be replaced. I only have 32000 miles on the vehicle.
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.
On Two seperate occasions, the message telling me to "Shift into P, and then desired gear." appeared while driving. I shifted into P while parked at an intersection both times and the car died. The second time it happened as I was driving away from Rairdon's Jeep in WA. I made it one street after having my ignition system replaced to the tune of $2,600. Was able to turn the car around and get it back to them. They have had my car for almost a month and state there is no error code, so they cannot diagnose.
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 a known production issue.
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.
The contact owns a 2021 Jeep Grand Cherokee. The contact stated that upon starting the vehicle, the messages "No Seat Belt", "Service Air Bags", "Service Seat Belts" and "Auto Park Disabled" were displayed. The contact stated that the failure had occurred with the driver and the front passenger's side seat occupant wearing their seat belts. Additionally, the brake and the check engine warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the Occupant Restraint Controller (ORC) had failed, and the loss of communication with the ORC had caused the electrical failures. The contact related the failure to NHTSA Campaign Number: 21V873000 (Air Bags), but the dealer informed the contact that the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 101,000.
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.
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.
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.
have a delaminating touchscreen which is causing a safety issue.
I went to put the car in park from driving and the car began jumping. The air conditioning fan stopped working inside the cabin. The air conditioning is not working in full speed and is not blowing hot out cool air.
The contact owns a 2021 Jeep Grand Cherokee. The contact stated that while the vehicle was parked and turned off, the headlights flashed off and on and the horn activated. The contact stated that eventually the vehicle failed to start and was towed to the local dealer who diagnosed that Body Control Module (BCM) was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 47,100.
The auto stop-start feature not functioning, with a message "Stop/Start Unavailable Service Stop Start System Now
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.
This Car have a lot issues we the computer in the car, the car I was missing oil in the engine ,the piston. Blows out No light 💡 engine On the car have a lot problems we trans mission No light On,I Have problems we transfer Case No light on, Now still having problems if backups sometimes is No light on,I don’t know if Normal but if have a lot safety concerns in this car.
Vehicle will randomly shut off with "Shift to P" message on dash. No warning lights or errors found very unsafe to drive.
Vehicle shifts from park to drive jumping gears ,making loud noises, Accelerating by its self and jumps aggressively into gear. Transmission is slipping, late engagement when shifting, and shifting rough. sometimes it will low rpm. Rpm is going up and down. Making total transmission failure and transfer case failure. Melting the hot and cold lines. Mechanic found aluminum melted and oil burn. Rpms fluctuate and gets hung up during shifting while driving.
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.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
