| Aug 2025 | ENGINE | Since the beginning of this year, vehicle began to misfire. So far I have spent over $2000 in repairs including replacing spark plugs, ignition coils, fuel injectors and oil cooler and vehicle continues to misfire and blow white smoke from exhaust. I have been advised that it may be a head gasket issue, which could cost anywhere from $3000 to $5000 but could cost more in the event the engine needs to be completely replaced. | Crash: No Fire: No | Unknown |
| Aug 2025 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | My 2018 Jeep Grand Cherokee Overland is experiencing serious electrical malfunctions related to the Uconnect radio head unit. This component appears to control or influence multiple vehicle systems beyond just audio, including climate control, backup camera, navigation, and possibly driver assistance features. The system malfunctions frequently and erratically — settings change on their own, the screen goes black or freezes, and controls become unresponsive while driving. These distractions create a serious safety hazard, as I am forced to take my attention off the road to regain control of basic functions like defrost or audio volume. I have discovered that this issue is widely reported by thousands of Jeep owners from this model year and earlier, particularly those with Uconnect systems. Jeep has refused to address or recall the problem despite it clearly impacting driving safety and vehicle usability. This malfunction significantly impairs my ability to operate the vehicle safely. I respectfully request that NHTSA investigate this issue as a potential safety defect. I have taken my car to the dealership and was advised that the whole radio unit needs to be completely replace. I have contacted Jeep and inquired about it, they told me they are aware of the issue but at this time, unless the car is under warranty, they do not offer any financial assistance. And it is a rather expensive issue to fix considering there is no fault of the car owners that the items installed in their vehicles are faulty. | Crash: No Fire: No | Unknown |

The vehicle was not repaired. The failure mileage was approximately 67,000. | Crash: No Fire: No | 67,000 |
| Aug 2025 | ENGINE AND ENGINE COOLING | The contact owns a 2018 Jeep Grand Cherokee. The contact stated that while driving for approximately 10-minutes, there was an abnormal knocking sound coming from the vehicle while depressing the accelerator pedal. The RPM lowered and the vehicle failed to respond while depressing the accelerator pedal. There was no warning light illuminated. The failure persisted, and the contact coasted into a parking lot and there was an excessive amount of yellow-grayish smoke coming from the engine compartment. The contact exited the vehicle and became aware of an unknown liquid pouring onto the ground underneath the vehicle, with little pieces of debris and sparks igniting underneath the vehicle. While the contact was on the phone with 9-1-1 Emergency Services, there was a popping sound coming from the vehicle and underneath the hood and over the windshield became engulfed in flames. The Fire Department arrived at the scene and extinguished the fire. A fire report was filed. The contact sustained severe emotional distress because of the failure but had not sought medical attention. The vehicle was towed to an independent tow facility where the vehicle remained. Upon investigation, the contact linked the failure to NHTSA Campaign Number: 20V699000 (Engine and Engine Cooling). The contact stated that the Insurance Company had not yet determined if the vehicle was a total loss. The dealer and manufacturer were notified of the failure but offered no assistance. The failure mileage was approximately 104,000. | Crash: No Fire: Yes Injuries: 1 Towed | 104,000 |

| Jul 2025 | ENGINE | Rockers & cam shaft are worn and making ticking noise. I only have 86k on my 2018 Jeep Grand Cherokee, and am diligent with upkeep on the maintenance. This is a very known issue and should be recalled as I have not driven it anymore to prevent further damage to the engine, and also don't have the funds to fork out almost 5k. | Crash: No Fire: No | Unknown |
| Jul 2025 | UNKNOWN OR OTHER | I own a 2018 Jeep Grand Cherokee with the Uconnect 8.4" touchscreen. The screen has begun to delaminate—a well-documented and widespread issue in 2017–2019 Jeep models. As the touchscreen separates from the display, it causes ghost inputs and malfunctions in key systems: - The radio and Apple CarPlay are unusable - The screen randomly calls contacts, including emergency services like 911 without my consent - I’ve had to disable Bluetooth on my phone to prevent unintended calls and inputs - The issue prevents safe and legal use of my Drive Safe & Save Bluetooth beacon from my insurance company Multiple Jeep dealerships quoted between $1,000–$2,000 for repairs, despite this being a known defect. The vehicle is out of warranty, but this malfunction poses a safety hazard. I am filing this complaint to request that NHTSA investigate this issue and encourage Jeep/Stellantis to issue a recall or extended warranty coverage. This issue is not cosmetic—it compromises driver focus, emergency call systems, and critical controls. Many owners are experiencing the same failure with no accountability from the manufacturer. | Crash: No Fire: No | Unknown |
| Jul 2025 | UNKNOWN OR OTHER,ENGINE | I have been without a vehicle for over 5 months. Paying on a vehicle that I cannot even get out of the garage. Paying storage insurance on a vehicle. There is a major issue with camshafts right now. I have had the spark plugs changed, coils, oil and I was waiting on the camshaft which is on back order for who knows how long. This needs to be addressed and recalled. With the amount being over 14,000 parts on back order I think this should be recalled. Even people who have had the camshaft fixed are still having engine issues with the 3.6L. Please do something about this, I have put so much money into this and I need a vehicle. At 75,000 miles this should not be happening. | Crash: No Fire: No | Unknown |
| Jul 2025 | ELECTRICAL SYSTEM | Urgent Safety Concern Regarding Defective Uconnect Radio System Shortly after purchasing my vehicle from Bertera in Westfield, Massachusetts, I began experiencing issues with the radio and related components—namely, erratic or "ghost" activity. I returned the vehicle to the dealership on multiple occasions; however, because the issue failed to replicate while in their possession, they were unable to offer any resolution. The problem persisted intermittently, but escalated significantly during a visit to Logan Airport. While curbside, the vehicle began behaving erratically: the exterior lights flashed, doors locked unexpectedly, heated seats activated, windows became unresponsive, and the vehicle could not be exited—even when approached by a security officer. After powering down and waiting for several minutes (with permission from security, as we exceeded our time limit), the system reset.Despite this dangerous scenario, the dealership again reported they could not reproduce the issue and offered no corrective action. On June 11, in preparation for a trip to Boston, I brought the vehicle to Bedard Brothers in Cheshire, Massachusetts—a certified Jeep dealership. Their technician determined the radio screen was delaminated and causing unintended inputs. They informed me that since my warranty had expired, the repair would cost more than $1,400. On [XXX], during travel to Massachusetts General Hospital, the malfunction occurred again: the heated seats engaged and would not turn off (despite temperatures nearing 90°F), the radio volume spiked uncontrollably, and the prior array of electronic malfunctions returned. Fortunately, I was able to attend the appointment and make it home safely. I have contacted Stellantis, Uconnect, and the Massachusetts Attorney General’s Office. While Stellantis expressed sympathy, they stated they could not offer assistance. My research has revealed multiple similar complaints from other vehicle owners. Any help greatly appreciated.

| Jul 2025 | ENGINE | As many others have reported, only 56K miles on this 3.6L Grand Cherokee. When I engage the passing gear an auto stop/start light comes on on the dash followed by the check engine light. Vehicle rides very rough (from a misfire). Taken to an independent shop; they changed plugs and coils but the problem persists. Also a knocking / ticking noise can be heard when accelerating. | Crash: No Fire: No | Unknown |
| Jun 2025 | LANE DEPARTURE,BACK OVER PREVENTION | Sensors that activate when objects are close to vehicle and are supposed to warn collision do not work at all. Sometimes they activate when there are no obstacles at all and the vehicle is stationary. Pedestrians are not noticed nor are objects/vehicles that are in the way as the vehicle is in motion (and even stationary). Also the system seems to reboot at will while driving. | Crash: No Fire: No | Unknown |
| Jun 2025 | LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | The Jeep Uconnect System control screen has delaminated form normal use which is a well documented issue on thousands of jeeps from online research. The delamination now has the vehicle pushing buttons on the screen by itself and changing safety parameters while driving. I have a video showing that while I am driving and not pushing any buttons the screen is frantically changing steering parameters, braking parameters, collision avoidance, lane departure, blind spot, etc. I have a video of the incident and screen doing this by itself. I can not upload it due to size, but please contact me for the video and I will send it. | Crash: No Fire: No | Unknown |
| Jun 2025 | ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL,SERVICE BRAKES | I purchased a 2018 Jeep Grand Cherokee on [XXX] unaware that the vehicle was subject to a federal safety recall and stop-sale order. The recall (NHTSA 24V-838 / Manufacturer 94B) was issued on November 7, 2024, for a defect in the ABS control module that may disable the Anti-lock Braking System (ABS), Electronic Stability Control (ESC), and cause unintended vehicle movement even while stationary. A stop-sale order (VIR 2024-11-14) was issued by Stellantis on November 14, 2024, prohibiting the sale or delivery of affected vehicles until repaired. Despite this, the dealership sold me the vehicle while the recall was still open and unrepaired. In the months following my purchase, I began experiencing issues with the Electronic Throttle Control (ETC). On June 15, 2025, I paid $770 out-of-pocket for ETC sensor repairs after a loss of throttle response. The vehicle has not yet been inspected by the manufacturer, but this defect may be linked to the broader electronic issues cited in the recall. No warning lights appeared in advance. I have been driving this vehicle daily without knowing it could malfunction in a way that puts myself and others at risk. I only learned of the recall on June 22, 2025, when I searched the VIN through NHTSA’s database. This has caused emotional distress, financial harm, and a complete loss of trust in the vehicle’s safety. I am seeking appropriate accountability for the illegal sale of this recalled vehicle and want to ensure others are not put in similar danger.

| Jun 2025 | POWER TRAIN,ELECTRICAL SYSTEM,ENGINE | I was driving my 2018 Jeep Grand Cherokee Laredo 4x4 on the highway at approximately 65-70 MPH, when suddenly the car started sputtering and my check engine light came on and started blinking. The car was essentially not drivable, so I pulled over at a gas station and had the car towed. This is dangerous as I was going uphill, and could have caused an accident, or worse. I did not have a check engine light prior to this! The next day the car was inspected and diagnosed by independent service center, who said there was a cylinder 4 engine misfire, so they replaced the spark plugs and the coils. Car was fixed, or so I thought, fast forward a couple months later while driving to work, same issue (misfires and sputtering) occurs again and coolant now runs low even though there are no visible signs of coolant leakage. I spoke to the independent service center and they mentioned there might be an issue with the engine such as a head gasket or fuel system. I got the Jeep towed to get checked, it was confirmed that it was an engine issue, especially the head gasket, camshaft, pistons, and lifters, and that I was going to need a new engine and it would cost between $8500 - 13000. My Jeep has approximately 83K miles. The issues I describe here with this engine are all similar to those that have been reported. | Crash: No Fire: No | Unknown |
| Jun 2025 | ELECTRICAL SYSTEM,SEATS,VISIBILITY/WIPER | The 2018 grand Cherokee has issues with mother board and electrical ghosts. 1st it was headlights and dome lights. they would flicker. i had to change the front lights 2x in a year. i thought this was odd. never did this with any car before. then I was driving home from work during rush hour and it started to rain. started the wipers front and back. the back wiper started and went halfway and got stuck. what happen? the front wipers went on for several revolutions (say 10-20 ) then stopped. started again. then stopped again. the rain intensity grew. Now the -wipers would only work when turned in opposite direction (the manual 1 pass move). this happened as i was trying to get home and stuck bumper to bumper on [XXX] . on this dangerous highway in middle of now a torrential downpour the front wipers now decided it wouldn't work AT ALL. i couldn't see anything and veered off to the shoulder thank god - waiting for rain to stop and then safely proceeded home. the next day the wipers worked. no check engine or anything. this goes on for a week or so with no issue. then out of nowhere the driver seat decides it has a mind of its own and pushes me all the way to the steering column. it wouldn't return when pushing the back button. i had to drive like that for my trip and then it magically went back upon restart. i take to dealer. pump motors bad on front and back. i say not sure your correct and explain. motor changed on front. not fixed. ok we think its the BCM. changed not fixed. finally the PDM was changed and wow it worked. 2 weeks at dealer and this shows that this issue with the control module is certainly risking peoples safety. i hope Jeep does the right thing and prevents a serious catastrophic event. read on the jeep electric issues and my vehicle had a previous "corrected" recall for Electrical Cruise Control. I dont think the fireware updates or software changes fixed all the bugs. be safe out there jeep INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |

| May 2025 | SERVICE BRAKES, HYDRAULIC | The contact owns a 2018 Jeep Grand Cherokee. The contact stated that while driving at an undisclosed speed, the brake warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed with ABS system failure. The contact was informed that the ABS system needed to be replaced. The vehicle was not repaired. The contact received notification of NHTSA Campaign Number: 24V838000 (Service Brakes, Hydraulic); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure and a case was filed. The failure mileage was 57,216. VIN tool confirms parts not available. | Crash: No Fire: No | 57,216 |
| May 2025 | ENGINE | Head gasket/engine failure. Constant check engine light. First it was for a misfire and my engine was overheating. Had oil clogging the filter even though it was changed within the appropriate mileage. I got the check engine fixed April of 2024. May 20,2025, head gasket blew, causing me to now have to replace my engine completely. Same issues as previously reported | Crash: No Fire: No | Unknown |
| May 2025 | ELECTRICAL SYSTEM | The main screen in the vehicle delaminated and caused quite a number of issues. Heated seats would randomly turn on and off and the temp on gbe seats would not go down, phone would call people over and over including 911, compartment heat would randomly turn on the highest setting and would not turn down, goo like substance came out of screen into the storage compartment below the screen, getting all over items stored. The radio would constantly change stations. All the issues became true safety hazards. I called their 800# and was referred to a dealer who charged me over $1000 with no remorse from Jeep. I am a 25 year owner of jeeps and not too pleased with the lack of response from Jeep. My next car will not be a Jeep! | Crash: No Fire: No | Unknown |
| May 2025 | SEATS | The active headrest on the driver's seat deployed spontaneously on it's own during normal operation of my vehicle. The headrest is now unable to be reset as it appears some components of the active headrest mechanism were faulty. This put my safety at risk as a driver as the active headrest can not activate in the event that it needs to activate during a possible collision. The headrest and seat causes strain and injury to my neck while driving as it is now positioned forward from the seat. This also causes strain to the rest of my spine. This issue is not covered by the original dealer that sold me my vehicle. There are no warning lamps or messages that have appeared since this problem first occurred. | Crash: No Fire: No Injuries: 1 | Unknown |
