2021 Jeep Grand Cherokee Complaint Log

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 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.

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.

The contact owns a 2021 Jeep Grand Cherokee. The contact stated that while the vehicle was parked with the headlight switch set to the Automatic Off/On position, the headlights blinked continuously, the bulb became red, and then the headlights became inoperable. While the headlight switch was in the on position, the headlights operated as designed. There was no warning light illuminated. The vehicle was not taken to a dealer but was not repaired. The manufacturer was not notified of the failure. The contact associated the failure with NHTSA Campaign Number: 21V950000 (Exterior Lighting); however, the VIN was not included. The failure mileage was 70,000.

Fuel pump loosing prime it cracks either in housing or hose internal to the tank and it causes it to loose prime. Long Crank Times/No Start And stall and rough idling at stoplights and upon acceleration. Issue was confirmed and reproduced by independent service center.

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.

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)

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

I was driving on the highway. There were no other vehicles nearby. I heard a loud pop/bang. I thought a tire burst but then discovered the back windshield had shattered

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.

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.

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.

REPEATED CAM SHAFT FAILURE. THE VEHICLE HAD A SUDDEN LOSS OF POWER. THIS HAS HAPPENBED THREE TIMES IN THE LAST 12 MONTHS. IT IS CURRENTLY AT A STELLANTIS DEALERSHIP IN MICHIGAN. THERE IS USUALLY N O PRIOR WARNING. THE CHECK ENGINE LIGHT COMES ON AS SOON AS THE ISSUE STARTS.

The screen for mapping other controls is delaminating, creating a safety and distraction hazard

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.

I am reporting a potential safety-related defect involving my Chrysler vehicle equipped with a V6 Pentastar engine. During a routine oil change a few weeks ago, I was informed by the service provider that my engine oil level was extremely low, despite the oil change being performed earlier than the recommended interval. This was alarming, as the vehicle had not shown any warning lights or obvious leaks. The service provider advised me that Chrysler vehicles with the V6 Pentastar engine have a known issue related to a defective engine seal that can cause excessive oil consumption. I was told that Chrysler is aware of this issue, that it has been the subject of class action lawsuits, but that it has not been formally recalled. I have since submitted my information to a class action settlement related to this issue but have not received any response. Due to the risk of engine damage, sudden failure, or safety hazards while driving, I believe this issue should be formally reviewed and documented by NHTSA. I am submitting this report to help document a potentially widespread defect that may affect vehicle safety and to ensure appropriate action is taken to protect consumers.

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

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.

My jeep started on fire in my garage. I put my items for the day in my jeep then started it the garage door was open. I started it at 0557. I went and got my son dressed brought him to the living room I heard noises from outside in the garage. I opened the door in the house to the garage, and it was full of smoke. There were flames coming from the front of the jeep. I called 911 at 0603. What component or system failed or malfunctioned, and is it available for inspection upon request? UNKOWEN How was your safety or the safety of others put at risk? The jeep engulfed in flame very quickly. If it wasn't for the quick thinking of my fiancé our home would have been a total loss as well. Has the problem been reproduced or confirmed by a dealer or independent service center? No, I have a complaint going with the BBB Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Police yes my jeep was bunted to the frame. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, I have had no issues with my jeep.

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.

Transmission failure at 19,481 miles in my 2021Jeep Grand Cherokee Limited 4x4 V6. The vehicle has not been abused, and the mileage is low for its age. The symptoms—erratic shifting, limp mode, and “Service Transmission” warnings— are consistent with a known defect pattern affecting multiple FCA vehicles using the same transmission.

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.

Hesitates to start

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

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.

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.

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.

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.

The high beam lights are not working. Dealer said the shutter door internal to headlamp assemblies are unresponsive. BOTH headlamps went out at the same time. Dealer said they haven't seen any issues before with the high beams.

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

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.

The contact owns a 2021 Jeep Grand Cherokee. The contact stated that the vehicle was idling abnormally fast. Additionally, the contact stated that upon releasing the brake pedal, while the vehicle was in drive(D), the vehicle accelerated unintendedly. The contact stated while driving 25-35 MPH and depressing the brake pedal to make a turn, the vehicle failed to decelerate as needed, causing the contact to pass the turn and almost caused a crash. The contact pulled over to the side of the road and turned around. There was no warning light illuminated. The vehicle was taken to the Nissan dealer where it was purchased, but the vehicle was not diagnosed or repaired. The Chrysler dealer and manufacturer were not notified of the failure. The failure mileage was approximately 53,354.

Back up camera fading out and dangerous to try and back up with camera messed up.

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.

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.

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 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.

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.

The air conditioner compressor blew at 58,000 miles. No certified jeep dealership in the area had the equipment necessary to replace it. I went to an autobody shop with that capability who said at that mileage this should not have happened in a well maintained car. It is $3000 to repair. This happened mid summer with high heat temperatures and no cold air. This put me at risk for hyperthermia as well as my dog. Oliverian Auto in Pike NH confirmed the issue. No warnings from the car, just no cold air, only hot air. First happened in July of this year.

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.

Vehicle will randomly shut off with "Shift to P" message on dash. No warning lights or errors found very unsafe to drive.

The leather of the dash that covers the airbag area has become unglued completely and is wrinkled all across the dash, and I am concerned the safety crash features will not work correctly now with premature failure of the adhesives that hold such a large area on the dash.

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.

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.

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.

The vehicle (2021 Jeep Grand Cherokee) was on the road for about 90 minutes when the engine shut off for no reason at 65 mph in noon rush hour traffic. We were in the left lane and had to coast through 2 lanes of traffic and an exit approach while trying to avoid a deadly crash with high-speed traffic. There were no warning lights or alarms on in the car. The only message was that we needed to put the car in park to restart. We finally came to stop and waited a minute and restarted the engine and were able to make it home. I called the dealer, and the next appointment was 3 weeks out. I tried driving during a rainy day before the dealer appointment and the vehicle shut off 3 times in 3 blocks, so I returned home and waited for the appointment date. As of today, the dealer says there are no codes and in 2 test rides the car is running just fine. This is a huge safety issue and I hope that we can get help before anything happens again.

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 failure occurred in heavy traffic Driver was stranded in a live lane The issue appears related to core electrical/fuel systems I have identified over 20 similar complaints from Jeep owners of their cars also shutting down in traffic, often without warning. These have been shared on owner forums and consumer boards. I believe this indicates there is a wider pattern that may indicate a safety defect.

Once you start driving after letting the vehicle sit the transmission will “slip” multiple times jerking the car and everyone in it. Occurs every day around 4 pm and various times
