ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Forward Collision Warning has been disabled since a forced OTA software update in August of 2024. Jeep has issued a STAR report to their dealers (S248A000013). Jeep acknowledges it is an issue, but fails to cover the remedy. Dealer wants $200+ to diagnose plus the cost of the software refresh. The system forces you to take the software update, removes a key safety feature, and then Jeep wants you to pay to restore it. This is a major issue with this model covered in the forums and should be addressed via recall. [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

SERVICE BRAKES
Was driving the vehicle normally, roughly 33,300 miles. All of a sudden, multiple malfunction lights came on, I believe the ABS and something else, can't remember which one. When we applied the brakes , there was no assist, we had to depress the pedal all the way down and basically stand on it to slow down and still ended up stopping partway through an intersection due to the lack of power brakes, we were extremely fortunate there was no other vehicles driving through or stopped in front of us, it could have killed us and/or other people. As the vehicle is out of warranty (by time) we looked into it ourselves and determined there were two DTCs, U0418 (invalid data, brake system control module) and P057B (Brake pedal position sensor circuit range/performance). We looked at the brake pedal and determined that a primary component of the "brake pedal simulator sensor" which is a part of the entire brake booster assembly. The retaining cup for the spring and internal components had come separated from the main body and caused the sensor to go out of range and the computer to disable power brakes entirely relying entirely on the backup hydraulic master cylinder. As this required replacement of the brake booster we decided to have it towed to the dealership to deal with. It was a few weeks before we had it towed and while it sat in the driveway the module not going to sleep resulted in both the main and aux batteries being fully drained and ruined, requiring replacement. The dealer replaced the power booster and provided the old component at our request for the purpose of filing this report in case it is requested for an investigation. The total cost was $1800. We consider this a severe safety issue and thus am filing this report with all documentation and have the part on hand if requested.

SUSPENSION:REAR:SPRINGS:COIL SPRINGS, SUSPENSION
I was driving on the NYS thru way with my family and my rear suspension coil came out while we were driving. The part was not rusted or looked defected. When I took it to the dealership they said a recall for this issue had been repaired in June of 2023 prior to me owning it. I purchased the vehicle on October of 2024. I called corporate and they said there is nothing they will do for me. I paid $500 to fix an issue that should have been completed properly. This is now a safety concern for me and I fear driving it will happen again.

ENGINE
Engine failure while driving on the highway. Jeep dealership confirmed failure due to a cylinder 4 misfire. Spark plug in cylinder 4 porcelain came out of the plug and resulted in damaging the pistons and valves. My family's safety was put at risk because we were driving on a highway and suddenly the engine stopped working. Could not accelerate or keep the engine running. Issue confirmed by the service team at local Jeep Dealership where car broke down. The team provided images of exploded spark plug and pieces of it in pistons and valves. Vehicle is in process of being transferred to dealership where car was purchased so that it can be inspected further by manufacturer. Police was not involved. A claim has been opened with insurance company, but they have not inspected it yet. There were no warnings prior to the engine failure. It just happened out of the blue.

ENGINE, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Two issues- 1. When pulling out into traffic the engine/gas did not catch and we slowly creeped out across lanes before the gas took. This almost caused us to become t-boned by a passing car. When the gas took the car lurched forward fast which could have been another accident. 2. When driving with adaptive cruise control the forward collision warning fault light and service adaptive cruise control light kept turning on and off with a service needed message on the heads up display. This flashed on and off repeatedly causing driver distraction and also limiting vehicle safety. This vehicle has been taken to the dealership multiple times since purchase with various resets done (Transmission control module, powertrain control module) and still numerous panel error lights turn on (engine malfunction light, traffic signal recognition fault light) and issues occur (ac stops blowing cold air, inside screens freeze) but can never be replicated or fault code founds. The biggest safety issue is the lagging engine/gas that randomly occurs from a stop as you can’t predict when it’s going to happen and it will cause an accident at some point.

POWER TRAIN, ENGINE, UNKNOWN OR OTHER
On 7/16/2026 exactly 1 week after i purchase the vehicle after fueling i drove about 1 mile when the car started to misfire, when attempting to accelerate. Check engine light flashes a few times and then went off. I then attempted to reverse into my driveway and when attempting to do so the vehicle shut off completely. But started right back up. I then called the dealership and was asked to bring it in. The dealership has the vehicle about 2 days and said it has been repaired it had bad spark plugs. When to get the car it drove fine with no issues until 7/28/2026 when i made an attempt to drive to work, i had driven about a mile from my home and car to a red light when the light turned green i attempted to accelerate and the vehicle was hesitate. Then a few warning lights came on that showed issues with electronic throttle control and electronic stability system service. The car would not accelerate over 20 mph and would shake when i attempted to press on the accelerator, the car was then towed to the dealership and much it has been at since 7/28. I received a online request for service approval from the tech on 7/29 in which they stated cylinders 1 &4 were showing misfired and they would look into replacing the spark plugs but that they would continue to work on the car. I then received a message from my service advisor on 7/31 that stated the spark plugs were replaced but the vehicle was still having issues, i should wait until 8/3 for an update. I have not even had the vehicle for 30 days and it’s been in the shop twice for the same issue with about 1,000 miles on it.

FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, ELECTRICAL SYSTEM
The initial safety issue began with the rear-view camera going blank and the Uconnect 5 screen freezing while the vehicle was operating in reverse. My vehicle's service record indicates that Safety Recall 24V-436 / FCA Campaign 79B was marked as "Completed" in the FCA system on June 19, 2024—even though the official recall was not initiated until around June 25, 2024, and no physical software update was performed at that time. To resolve the recall, I took my 2022 Jeep Grand Cherokee L to Performance Chrysler Dodge Jeep Ram in Delaware, Ohio, where technicians updated the software to version FCA-MY24.U33.43-PROD. Immediately following this dealer update, several core vehicle and safety functions failed: Forward Collision Warning (FCW): The FCW system automatically turned off, and the option to re-enable it completely disappeared from the vehicle settings menu. Vehicle Safety & Operational Controls: Automatic speed-sensitive door locking and paddle shifter functionality were completely disabled. I returned the vehicle to the dealer, where technicians reflashed the software to restore the user configuration options and re-enable FCW. However, the Uconnect system remains dangerously buggy: Active Safety Alerts: The amber FCW OFF light illuminates continuously and gets stuck on. While ADAS features appear partially operational, the constant amber warning obscures real-time system failure notifications. Backup Camera & System Latency: The Uconnect system routinely freezes, introducing a dangerous delay in the rear-view camera feed during reversing maneuvers. System Instability: The Uconnect software randomly resets to the Italian language, resets rear-camera display settings, disables automatic door locking, disables paddle shifters, and causes seat auto-adjustment malfunctions. Stellantis has since issued TSB 08-221-26 (Software Version U41.10), which explicitly acknowledges that these exact software bugs—including the persistent FCW OFF light, screen freezes,

ENGINE
I am the owner of a 2026 Jeep Grand Cherokee L equipped with the 2.0L Hurricane 4 Turbo engine. At approximately 3,500 miles, the vehicle experienced a spark plug failure/breakage. The vehicle was taken to Nyle Maxwell dealership in Austin, Texas, where a spark plug was found broken and was replaced under warranty on 5/15/2026 after a lengthy wait for the parts of 11 days. This same failure occurred a second time at approximately 4,900 miles on 7/13/2026. The vehicle was again taken to the Nyle Maxwell dealership for repair. Both failures occurred while operating the vehicle on 87 octane regular unleaded fuel, which is the fuel grade stated as acceptable in the owner’s manual. I am concerned this is a widespread issue, as other owners of this same engine report similar spark plug failures using 87 octane fuel, per online owner forums. I am filing this complaint to document the pattern and request that NHTSA investigate.

SEATS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I am experiencing two serious issues with my Jeep that have raised significant safety concerns. First, the front passenger seat's lumbar bladder repeatedly inflates on its own, making the seat extremely uncomfortable and causing severe back pain for anyone sitting in it. I have been informed that this is a known issue affecting many Jeeps of this model. The dealership previously deflated the lumbar bladder under warranty, but now the problem has returned. I was told I must pay for the repair out of pocket because the previous deflation supposedly voided or disqualified the warranty coverage. I do not believe I should be responsible for paying to fix a recurring defect that was previously addressed under warranty. Second, the Electronic Brake System (EBS) warning light comes on randomly, and when it does, my vehicle unexpectedly slows down or comes to a stop. This creates an extremely dangerous situation while driving. I have been fortunate to avoid a collision so far, but I am very concerned for my safety and the safety of my four children, who regularly ride in the vehicle with me. I am requesting that these issues be thoroughly investigated and repaired at no cost to me, as they involve recurring defects and serious safety risks. I also request a written explanation of why my warranty claim for the recurring seat defect was denied after the dealership's previous repair.

ENGINE
While driving my 2026 Jeep Grand Cherokee, the check engine light began flashing (a flashing, rather than steady, check engine light typically indicates an active engine misfire). At or around the same time, the vehicle began shaking/vibrating noticeably, consistent with the misfire condition indicated by the flashing light. Separately, I experienced a failure of the vehicle’s push-button Start/Stop ignition system. When attempting to shut the engine off by pressing the Start/Stop button, the engine did not turn off as expected. The button had to be pressed several times before the engine finally powered off.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
The dealership performed the backup camera safety recall (Jeep Recall 66B / NHTSA Campaign 24V436000), but the safety defect returned. The dealership is now refusing to re-repair the vehicle, falsely claiming the recall warranty has expired. The backup camera screen is blue and says camera is not available.

ENGINE, UNKNOWN OR OTHER
While driving from Tampa to Miramar Beach, Florida, the vehicle operated normally on the highway. However, shortly after exiting the highway and driving in slow traffic, the engine temperature gauge suddenly rose into the red zone, and the air conditioning automatically shut off. I immediately pulled over and allowed the vehicle to cool. The engine temperature returned to normal, and after the engine cooled completely, I found that the coolant reservoir level was only slightly below the MIN mark. There are no visible coolant leaks, no check engine light, and no warning messages currently displayed.
