2021 JEEP GRAND CHEROKEE Complaints

-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

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.

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.

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.

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)

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 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.
