2021 Jeep Grand Cherokee Problems

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.

Steering is erratic while driving. Car is shifting left and right by itself while driving down the road feeling like the tires want to go different directions from one another. Steering wheel makes noticeable movement on its own left and right while going down a straight smooth road.

The contact owned a 2021 Jeep Grand Cherokee. The contact stated that while making a left-hand turn, the wheels on the vehicle failed to follow the trajectory of the movement and failed to function as intended, and moved toward the curb. The vehicle came to a stop when it hit the curb. It was unknown if any warning lights were illuminated. The driver-side and passenger-side air bags did not deploy. The contact exited the vehicle, and upon inspecting the vehicle, the contact noticed that the front right and rear passenger-side tires were facing inwards. The vehicle was towed to a collision center. The contact was not injured. No police report was filed. The insurance company was notified and deemed the vehicle a total loss. The failure mileage was approximately 127,000.

My son’s car drifted to the right past the white line and he ended up hitting a hydrant and continued at least 100 ft before stopping. Our dash cam showed a slow smooth drift to the right without any lane assist being activated to pull the car back. All safety features were activated and turned on the day we bought the car for him. It was the main reason we chose this model. He is very lucky to be alive. After the impact, the car just barely missed a business sign, a telephone pole and a tree. The car was declared totaled. Unfortunately, the total amount the insurance is offering is about 4k short of what we still owe. Words cannot express how lucky we are that our son is okay, but we are very angry that the features we bought the car for, failed him.

I was driving north on I64, and a car in front of me suddenly stopped. Cruise control was on, but when i applied the brake, my car did not stopped, and cruise control speed up, before decreasing speed. Instead of turning off, and allowing the car to slow down. I had to swerve, causing to go off on the side of the highway, and held my foot on the brake for almost a mile, along the side of the highway, before the car came to a stop

-Thermostat -car died in traffic -not that I know of -it was diagnosed by the dealer -no warning lights or lamps -not that I’m aware if

Electronic Throttle Control warning light comes on upon starting vehicle while extended crank occurs. When starting car, the push to start feature will not turn over and continuously cranks multiple times. Issue is intermittent- never know when it will happen which makes it difficult to replicate at service center. Took car into 2 mechanics on separate occasions and finally to the Jeep dealership for service. Because issue couldn’t be duplicated- nothing was done. However, recently while driving, same extended crank pattern noise and unstable/rough propulsion occurred while driving on the highway. Same Electronic throttle control warning light came on along with the check engine light. Also cruise control and the auto On Off feature became disabled. I scheduled service with my mechanic as soon as possible and they found the stored code was related to Technical Service Bulletin 2014-004-25 REV.B. This bulletin lists the symptoms I described yet the dealership did not perform the fuel pressure Test and Replace Fuel Pressure Regulator. I called the dealership to schedule warranty service for this TBS and they gave me difficulty acknowledging the TSB was issued for my make/model/year and scheduling a service appt. I spent the last few hours reading all of the complaints on NHTSA for 2021 Jeep Grand Cherokee and it is alarming how many of the complaint are for this specific issue. It is dangerous for anyone on the road to be driving in a vehicle you can’t rely on to propel you forward when you press the gas or stall due to faulty fuel pressure regulator amid traffic. An investigation should be done. Furthermore, in reviewing other recalls, I found this is a recurrent issue for Jeep. It appears they’ve been various safety recalls issued for this in the past for vehicles made from 2011-2020. How they haven’t addressed it in new models is appalling. For owners of the vehicle, it’s difficult to have any leverage with dealership since it is not easy to replicate on demand.

The contact owns a 2021 Jeep Grand Cherokee. The contact stated that while driving at various speeds, the vehicle hesitated while depressing the accelerator pedal and attempting to overtake another vehicle. The RPM was extremely elevated; however, the vehicle failed to respond as intended. The contact pulled over to the shoulder of the roadway and restarted the vehicle before resuming normal driving. The contact became aware that, when shifting between automatic and manual driving modes, the vehicle operated normally without hesitating. The vehicle was taken to several dealers on several occasions; however, the dealer was unable to duplicate the failure or determine the cause of the failure. In addition, the headlights occasionally shut off unexpectedly while driving at night. The contact would pull over and wait for the headlights to return before resuming normal driving. The manufacturer was notified of the failure and informed the contact that there were no recalls associated with the VIN for the failure. The vehicle was not repaired. The failure mileage was approximately 50,000.

I was driving back from the airport and as it began to get dark, it became apparent I had no headlights. I somehow managed to drive the last two hours home on parking lights and lights from other vehicles.I took it to a Chrysler Jeep dealership Goldies in Huntington, West Virginia. The exam that I put a bulb in the driver side. In the passenger side, the LED portion is still glowing, but is yellow green and they told me it would require a headline assembly which would call somewhere between 1500 and $2000. The bulb alone was just over $500. They told me that the filaments had cracked in the bulb despite no apparent damage to the vehicle. I owned an accurate T from 2008 to 2021 I and it never required new bulbs. I actually don’t do much nighttime driving so they could not have many hours on the lights. I don’t know what but something is wrong here.

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 NHTSA to investigate a potential manufacturing defect in 2021 Jeep Grand Cherokee fuel delivery systems.

The contact owns a 2021 Jeep Grand Cherokee. The contact stated that while driving at an undisclosed speed, the ESC and “Service 4WD” warning lights illuminated, causing the vehicle to shake abnormally. Additionally, the transmission unexpectedly shifted to 4WD Low while driving. The steering wheel vibrated while making a turn, and the vehicle jerked. The vehicle also intermittently failed to start immediately and made a clicking sound. The vehicle was taken to an independent mechanic, who determined that the ABS had failed, and that the drive train control module and transfer case control module needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 34,000.

For my 2021 Jeep Grand Cherokee, the Antilock braking system, Hydraulic control unit has failed. It is currently being repaired by the dealership, and I will request the old part so that it is available for inspection. The failure of the ABS control unit, disabled the electronic stability control, the forward collision warning system and the cruise control - and the issue appears to be directly equivalent to the current Stellantis recall for Ram 1500's of a similar year. The dealer was able to reproduce the error - and was inspected at a Jeep dealership.

Every time I hit a bumb or hole. The back end slides around. I’ve almost wrecked 100 times. And my tires wear down on tge back. Pleaee do something befor I kill someone or myself. The jeep is not safe. This is my 4 jeep and have had alot of problems

BE ASVISED, THIS REPORT MAY BE INTERCEPTED, DELETED, HIDDEN, OR MODIFIED UPON RECEIVING. NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION Vehicle Safety Complaint Complainant: [XXX] [XXX] [XXX] Vehicle: 2021 Jeep Grand Cherokee ------------------------------------- SAFETY DEFECT COMPLAINT – POST-REPAIR VEHICLE CONDITION I am reporting a serious safety concern involving my vehicle following collision repairs performed by Gerber Collision & Glass under a claim handled by State Farm Insurance. After the repair, the vehicle began exhibiting multiple safety-related issues, including: - Steering instability and shaking - Engine performance issues and abnormal noise - HVAC malfunction - Persistent chemical and/or coolant odors - Physical symptoms while driving, including dizziness, lightheadedness, and shortness of breath I returned to the repair facility with photographic evidence showing parts with visible wear and damage that appear inconsistent with proper replacement. Despite this, no diagnostic evaluation was performed, and no corrective action was taken. The repair facility has refused to address the condition of these parts, and the insurer has refused to authorize further inspection. Additionally, there are discrepancies between the insurance estimate and the final repair invoice, raising concerns about whether the documented work matches what was actually performed, including work involving structural components such as the cradle/subframe. I believe this vehicle may be unsafe to operate and that the repair may have introduced or failed to correct conditions that pose a risk to driver safety. I request that this matter be reviewed as a potential safety defect related to post-collision repair. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

Was pulling into a parking spot on the 2nd level of parking garage and the Jeep accelerated and hit the cement wall at front of garage space. It accelerated on its own. The front of the jeep was crushed, and I ended up with a fractured sternum and a seat belt hernia which I will have surgery in the next couple of weeks. The airbags did not deploy. And I did not press on the gas pulling into the parking spot --- it just accelerated on its own. When I first got in the car the system showed that systems disabled, but the then the message went away. When I pressed seat one, it did not go in place and I had to adjust it on my own. I continued on to my dermitologist appointment , pulled into the the parking space and the instant brake when too close did not break and the air bags did not deploy. Thru me into the cement wall, and the whole front of the car was demolished, Not epairable.

Driver's seat belt retractor doesn't retract all of the time. Hangs up & leaves slack. Bought car & wasn't as bad. Didn't talk to dealer until now. Drove car 800 miles & 4 months since purchase. Dealer service dept says no extended warranty etc. I'm past the original warranty period & the 3 month certified used car warranty. Car was sold on Oct 14, 2025. The equipment checklist form marked that all safety systems were working. I feel a slack belt, getting worse is a safety issue the manufacturer should fix in a 5 year old car. Date is now when it's gotten really slow. It was somewhat that way at purchase. Needed to be shook to retract. Al

Buckle no longer works to buckle seat belt

Rear windshield randomly exploded. Defroster was NOT on, no rapid change in temps, nothing on the road, nor people around. I’d been driving 2-3 hours already on this morning it occurred. Temps were around 30-40f

To Whom It May Concern: I am writing to formally notify you of a serious and dangerous safety defect involving the vehicle I purchased from Carvana on February 2, 2026. On April 9, 2026, while driving on the highway at 70 MPH, my truck stopped abruptly after experiencing a critical wheel failure. Upon exiting the vehicle, I notice that all the lug nuts were missing. I immediately located a tow driver that confirmed what I observed. The tow company towed the vehicles to a Dodge mechanic in Paducah, KY. Upon inspection by a certified mechanic, I was informed that the wheel failure was caused by either a improperly installed loose or too tightened lug nuts, resulting in damage to the wheel hub and wheel assembly, which condition represents a severe safety hazard that could have resulted in catastrophic injury or death. Prior to the malfunction, there were no warning lamps or messages until the actual event. When purchased, Carvana represented that its vehicles undergo thorough inspections and are safe for operation. However, this incident demonstrates a clear failure in inspection, preparation, or mechanical servicing, including but not limited to: •Failure to ensure lug nuts were properly installed and secured •Failure to identify an obvious and critical safety issue •Delivery of a vehicle that was not roadworthy at the time of sale A wheel detachment risk is not a minor and or normal wear and tear as stated by Carvana's warranty company Silver Rock Warranty and Carvana Warranty support team. The malfunction was a fundamental safety failure that any reasonable inspection would have identified and corrected prior to sale.

Recalled Rear Coils, over 2-3 months ago, Taken to Jeep Dealership in Morgantown Wv, Taken for front ball joint knuckle pin coming lose, Causing the upper ball joint to start to make noise, unable to control steering when raining or going over bump video was send to mopar when claim and complaint at the time, Prior two weeks before also called and report it, someone canceled my call, and said they had no remedy at that time. Was told they had no remedy for recall at that time. Morgantown jeep then proceeded to fix the rear suspension coil recall. Never notified me the part that was recalled was in fact broken when it was removed. Instead replaced it then told me my rear suspension, Structs, and say bar links are broken on both sides of my rear end which mechanically is attached to these coils which is the resulting damages of driving the vehicle for 40,000 miles with improper installed coils. I report this to Mopar when giving them the car, the rear end always bounced. I went through my first set of tires in less than 18,000 miles due to this. My Case managers name was mary, She was very Rude. Called me a liar more than once. They would not even call me to come pick my car up. When talking to the Customer service guy at jeep in morganttown. He said mary said fix only the parts and only what the exact recalled said. and they would not evaluate or do anything for my Front control arm and pinch bolt, they tighted it, I even submitted photos where they just tightened it submitted to mopar. Also asked for submission of buy back program due to value dropping more than 10,000 dollars in 3 weeks time, Attempted trade off for 38,000- owed 42,000 in Octor 2022. Nov price dropped to 32,000 trade in. Value now for trade in due to severity of mechanical issues is now down to less than 28,000, I said 55,000 dollars for this car. I have a 2.5% interest rate and did not carry over anything over MSRP on this Vehicle. I am unable to trade it. And the vehicle is barely drivable.

I was sitting inside my home when all of the sudden I heard a loud boom, walked outside and saw my 2021 Jeep Grand Cherokee on fire. The fire started in the front and moved to the back of the vehicle. The engine had been off for about 2 hours and vehicle was sitting in the driveway. My son's car seat, stroller and many other belongings were ruined in the fire. A police report was not filed, but a fire report was.

While driving over Donner Summit (7000 ft elevation) on HWY 80 towards Reno, the Sun Roof shattered with a loud pop. Fortunately, the sun roof visor was closed so shattered glass didn't make it into the car. I have been reviewing online forums and have found there are other instances of this happening with a similar vehicle like mine which is a 2021 Jeep Grand Cherokee. https://www.jeepgarage.org/threads/shattered-sunroof.240280/

Passenger seat lumbar inflated out and won't go back down. It has also popped off the back plastic on the seat. This is a known issue as we have found multiple incidents online. It is causing discomfort and pain when sitting. No inspections yet as we fear it could cost thousands to fix with less than 50k miles on the vehicle.

Seat started moving to the 1st saved memory position while driving. This happened over and over and over until I got home. Now the seat memory for the 1st position has stopped working and number 2 is what the 1st use to be.

My vehicle has 22,000 miles on it. The dealer has determined that they are at 4/32 and are wearing prematurely. He also indicated that Jeep (Nielsen Jeep) is aware of this and it is simply unfortunate that all four (4) tires (Michelin Premier LTX, 265/60R18) on my vehicle wore evenly and prematurely. As I indicated to the dealership servicing my vehicle, the tires do not grip in inclement weather and often result in skids, a safety issue especially when my two 12yr olds are in the vehicle with me. Tire warranted at 55,000 miles should not wear prematurely and thus making it unsafe to operate the vehicle.
