2021 Jeep Grand Cherokee Owner Complaints

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.

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.

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.

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 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.

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

Over the past year, I've noticed a suspension-related squeak - increasing in frequency - coming from the rear of my 2021 Jeep Grand Cherokee Limited vehicle. I brought this to the attention of the Jeep dealer service dept where I purchased the vehicle, as well as to another independent auto repair shop, and both indicated they could not find anything wrong. Today, I saw news on the internet of the Jeep Grand Cherokee Limited "rear coil spring" issue as described in this Safety Recall report [XXX] and now believe the noise I've been hearing may be related to this recall.

Car has 28k miles. It is driven by a [XX] year old. It is a Jeep GC Summit which is top of the line for Jeep. Both headlights were blown and the dash warning system never alerted that the lights were out. Car is equipped with the headlight monitoring system. She never drives at night so I cannot give you an exact date but we think it has been out since 2024 which is the last Texas inspection it had and passed. Contacted Jeep Wave with concern and was blown off and sent to a VM which was never returned. You have a recall for the Laredo and Overland models but not the Summit. The DRL lights thankfully are bright but you still need headlights. Car has been set to auto for headlights due to her age. I am hoping you give this a serious look. I posted on Facebook and other people are having the same issues with the Summits. You have no headlights and nothing saying they are out.
