I purchased a new 2026 Jeep Grand Cherokee Summit equipped with the new 2.0L Hurricane 4 Turbo. The vehicle has a repeatable and potentially dangerous accelerator-response problem. From a complete stop, I can apply substantial/full accelerator input and the vehicle initially provides little or no expected acceleration. The vehicle may begin creeping forward and the tachometer may begin moving, but there is little corresponding engine sound or vehicle acceleration. After approximately two seconds, the vehicle begins responding and accelerating however it is still extremely sluggish and dangerous. The condition has been repeatedly reproduced in both Normal and Sport modes. I have also experienced delayed RPM increase and delayed transmission response/downshift while already moving. The condition has occurred when attempting to enter traffic and creates a safety concern because the vehicle does not immediately respond as expected to accelerator input. The dealership initially told me the vehicle was operating normally based on diagnostic readings amd that because of the computers and software there is no direct throttle response on these drive by wire vehicles anymore. That is simply intrue. The dealership subsequently had the shop foreman test drive with me in the vehicle. The foreman experienced the condition and agreed there was an issue with the lack of throttle response. I repeated the issue multiple times from stop, ehile turning, and at speed. The dealership is now involving a technical advisor. The dealer has told me that a Stellantis service bulletin concerning similar drivability symptoms does not apply to my VIN. I am not alleging that the bulletin applies to my vehicle. I am reporting the actual safety-related behavior because I believe it warrants investigation regardless of whether my VIN is currently included in that service action.

This complaint is being filed regarding a failed and botched remedy of two federal safety recalls: the Crankshaft Position Sensor recall and Safety Recall Z46 (High-Pressure Fuel Pump) on my Jeep Grand Cherokee EcoDiesel.The vehicle was delivered to Kendall DCJR of Soldotna, AK for the recall services. The technician performed the recalls, but the high-pressure fuel pump failed immediately, resulting in systemic fuel leaking directly into the engine's crankcase oil pan. The fuel contamination thinned the motor oil, dropped oil pressure, caused the oil filter to collapse, and resulted in a catastrophically blown motor.Physical inspection confirms the entire fuel system is filled with destructive metal shavings and debris ("glitter") from the disintegrating pump, requiring a complete replacement of all fuel components and the engine assembly. The vehicle has been rendered entirely undrivable and has been sitting out of service at the authorized dealer for over 30 cumulative days. The manufacturer (Stellantis/Jeep) has failed to provide a safe, effective, and timely remedy for these safety recalls, and is refusing to issue a Corporate Rental Authorization (CRA) or alternative transportation while my vehicle remains grounded due to the safety defect's failure. This is a complete failure to execute a federal safety recall remedy in a reasonable timeframe.

On November 23, 2025, I was driving approximately 60 mph in the middle lane of I-495 near Exit 62 in Marlborough, Massachusetts, with a passenger in the vehicle. I signaled to change lanes to pass a slower vehicle, selected Sport Mode, and accelerated. The engine RPM increased sharply and, almost immediately, I heard an extremely loud bang from the engine area. Multiple warning lights began flashing on the instrument panel, the vehicle made abnormal noises, and the engine lost power. The loss of propulsion was immediate while I was traveling at highway speed. Because that section of I-495 slopes slightly downhill and I was already close to Exit 62, the vehicle's momentum allowed me to reach the exit and pull onto the shoulder. Had this occurred in heavier traffic or in a location without a safe shoulder or exit nearby, the sudden loss of propulsion could have resulted in a collision. The vehicle became inoperable and required towing. It was later inspected by an authorized Jeep dealership. The dealer documented a hole in the side of the engine with engine fluid leaking out and determined that the engine requires replacement. The vehicle had approximately 94,298 miles at the time of the incident and had been regularly maintained. The same vehicle had previously experienced a significant engine problem in 2023 at approximately 67,987 miles, involving white smoke, a head gasket leak affecting cylinder 5, and replacement of the cylinder head. I am reporting this because the catastrophic engine failure caused a sudden and complete loss of propulsion at highway speed. The vehicle and failed engine remain available for inspection.

Component Failure & Inspection: The engine water pump assembly failed. This specific failure is a documented factory defect explicitly covered under manufacturer Technical Service Bulletin (TSB) #9100212 and tracked under NHTSA ID #10244344. The failed component was replaced by an authorized dealership; the physical part is not available, but full diagnostic logs and proof of failure are stored in the manufacturer database under University Auto Center invoice #6044139/1. Safety Risks: The water pump suffered a sudden, catastrophic structural failure while operating at highway speeds—a known vulnerability detailed in TSB #9100212 and NHTSA ID #10244344. This caused an immediate loss of engine coolant and a rapid spike in engine temperature. The vehicle lost power and was forced to make an emergency pull-off onto a busy highway shoulder, stranding occupants in a highly vulnerable position. A sudden cooling failure at highway speeds creates an immediate risk of engine seizure, vehicle fire, or traffic collision while disabled on the roadside. Dealer Confirmation & Inspection: Yes. The failure was inspected, reproduced, and confirmed by an authorized manufacturer dealership (University Auto Center). The dealer confirmed that the water pump assembly completely failed and required replacement, perfectly mirroring the defect parameters outlined in TSB #9100212. Warning Lamps & Prior Symptoms: There were no prior symptoms, noises, or early warning indicators. The component failed instantly without warning. The first indication was a sudden, rapid flashing of the engine temperature warning light and an "Engine Overheating" message on the dashboard cluster, immediately followed by a loss of power.

My 2013 Jeep Grand Cherokee equipped with the 3.6L Pentastar v6 has a persistent cylinder 2 misfire (P0302). The cylinder 2 spark plug, ignition coil, and fuel injector have already been replaced, but the misfire continues. Diagnostic testing with a scan tool confirmed that cylinder 2 accumulated 61 misfires during a single test while cylinders 1,3, 4, 5, and 6 recorded zero, and the misfire monitor reported " Fail this trip" the vehicle can appear to drive normally despite the active misfire. I became aware that Chrysler issued warranty bulletin x56 concerning the 3.6L left cylinder head on certain 2011- 2013 vehicles including select 2013 Jeep grand Cherokees. I contact a jeep dealer and advise that my VIN is not included in that warranty extension. I am reporting this because my vehicle is experiencing a similar cylinder specific misfire concerns and I believe this condition should be documented and investigated.

The contact owns a 2018 Jeep Grand Cherokee. The contact stated that since the vehicle was purchased, there was an abnormally strong coolant odor coming from the vehicle. The dealer was notified of the failure and informed the contact that the coolant reservoir was recently refilled, and the odor might be due to an overflow. The contact stated that the failure persisted, and the vehicle was taken to the dealer, where the water pump was replaced. The contact stated that the water pump had been replaced approximately nine times under warranty due to the strong coolant odor and a water pump leak; however, the failure persisted. The vehicle was not yet repaired. The manufacturer was notified of the failure, and a case was filed. The failure mileage was approximately 125,000.

Vehicle Information: 2018 Jeep Grand Cherokee Overland 3.0L V6 EcoDiesel 4x4Component Affected: Fuel/Propulsion System (High-Pressure Fuel Pump) Safety Incident Narrative: The vehicle previously underwent a mandatory manufacturer safety recall replacement for the Bosch CP4 High-Pressure Fuel Pump under FCA Safety Recall Z46 (NHTSA Campaign Number: 22V-406). At 111,948 miles, while operating the vehicle, the engine suffered a sudden, catastrophic mechanical failure accompanied by an immediate and total loss of engine oil pressure. This caused the engine to suddenly stall and lose all propulsion while in motion, creating an immediate and severe highway safety hazard to myself and surrounding traffic.The vehicle was towed to an authorized Jeep dealership under Repair Order #5823328. The manufacturer (Stellantis) and the dealership are currently refusing to authorize diagnostic teardown labor or a mechanical review of the internal safety recall componentry to investigate an acute internal fuel-pump shaft seal leak or residual micro-particle metallic debris from the prior campaign. An internal drive-shaft seal failure on this replacement pump architecture dumps raw diesel fuel directly into the engine's internal oil crankcase, causing severe oil dilution, an immediate collapse of structural oil pressure, and catastrophic engine seizure. The manufacturer is attempting to shift 100% of the financial burden ($25,000 engine replacement cost) onto the consumer, actively obstructing an essential safety failure investigation into a federally recalled component.

I am submitting this complaint to report a serious safety concern involving my 2020 Jeep Grand Cherokee. At approximately 44,000–45,000 miles, the vehicle suffered a catastrophic engine failure. This was extremely alarming considering the relatively low mileage of the vehicle. The most serious concern occurred while I was attempting to drive the vehicle to the service center. The condition of the vehicle became so severe that I genuinely feared the vehicle could catch fire while I was still inside it. I was terrified for my personal safety and concerned that I could be seriously injured. This was not simply an inconvenience or an ordinary mechanical repair. In my opinion, the circumstances surrounding the engine failure created a potentially dangerous safety situation. The vehicle has subsequently remained at the dealership/service facility for an extended period while the engine issue has been addressed. I contacted Jeep/Stellantis regarding the engine failure. Stellantis offered approximately $13,000 in goodwill assistance toward the repair while requiring me to contribute approximately $3,200. However, my primary reason for reporting this matter to NHTSA is not the financial dispute. My primary concern is SAFETY. I am extremely concerned that an engine could experience such a catastrophic failure at approximately 44,000–45,000 miles and create circumstances in which I feared the vehicle could catch fire while being driven. As a result of this incident, I have completely lost confidence in the safety and reliability of this vehicle and do not feel safe driving it again, even if the engine is repaired or replaced. I respectfully request that NHTSA review this complaint and determine whether similar engine failures, fire-related incidents, or safety complaints have been reported involving 2020 Jeep Grand Cherokee vehicles or vehicles equipped with the same engine. I am prepared to provide my VIN, dealership repair orders, diagnostic information, service re

On the 26th of April 2026, the transfer Case on my 2020 Grand Cherokee (with less 114,000 miles) failed during highway travel. This resulted in a sudden downshift and temporary deceleration followed by illumination of “Service 4wd” display. A short time after, the “Service Electronic Stability Control” indicator displayed followed by another downshift and the unattended transition of the 'Select_Terrain' from 'Auto' to 'Snow'. We were unable to turn off these settings. On the next day, we returned the Jeep to our CDJR dealer for repair. After inspection, the service agent reported that the Jeep experienced a “Transfer Case failure” and further recommended that I consider [purchasing] a new vehicle as these issues seem to be piling up. Failure of this nature is not normal wear. I have purchased 5 Jeep vehicles over the past 40 years and 4 of our Jeeps had over 250,000 miles of service without dangerous, catastrophic engine or drive-train failure such as this. This situation should remediated by the manufacturer and any affected components repaired or replaced. Finally, it should be noted that 3-days prior to the failure, the same CDJR dealer provided a 100,00-Mile 'service' that included "Op1 DMS All wheel Drive Fluid Exchange".

Vehicle Information: Year / Make / Model: 2022 Jeep Grand Cherokee Overland 4xe Component(s) Involved: Engine / Hybrid Powertrain / Electrical System / Sudden Loss of Drive Power Current Mileage: Approximately 48,000mi Incident Summary I am filing this complaint because my 2022 Jeep Grand Cherokee Overland 4xe has developed a dangerous new defect following an official recall service: the engine completely dies while accelerating on the highway. I took my Jeep to an authorized dealership to have the safety recall performed for the engine shutdown issue. Before this recall work was completed, I had never experienced the vehicle dying on the highway. Since the recall "fix," however, the engine has cut out completely 4 separate times while accelerating at high speeds. The most recent time happened today (August 3, 2026). Losing all pedal response and motive power in fast-moving traffic with no warning is terrifying and creates an extreme hazard for myself and everyone around me. History of Vehicle Issues & Extended Shop Time This sudden highway stalling comes on top of severe, ongoing electrical problems that have plagued this Jeep. Altogether, the vehicle has spent months sitting in the dealership shop, yet the problems remain unfixed: Post-Recall Engine Shutdowns: 4 separate complete power loss incidents while accelerating on the highway (latest occurrence: August 3, 2026). Unresolved Battery Drain: Ongoing parasitic battery drain that kills the battery, requiring multiple rounds of diagnostics without a solution. Pervasive Electrical Glitches: Frequent system glitches, including frozen touchscreens, instrument cluster reboots, random dash warning lights, and connectivity drops. Media Hub Issues: Hardware problems involving the media hub module. Requested Action The recall fix did not solve the safety hazard—it seems to have triggered a new, life-threatening stalling issue on the highway, along with the string of other issues, it's unsafe to drive.

The transmission fails constantly when we are accelerating - approxx 50-58 miles per hour the transmission freezes & the RMP's stay @ 4-5 thousand for 20-30 seconds - it fails to downshift. This is extremely dangerous at any time & can cause a major accident if the vehicle is stuck & you need to stop! We have have left the car several times for this issue & they keep telling us they cannot replicate the issue. (We are older & we are given looks like we are nuts)

Problem was Oil Filter housing made of plastic. It was cracked and no warning light that oil had leaked out. Car SUDDENLY DECELERATED as I was merging into traffic on freeway causing vehicles coming up behind to brake rapidly including a semi truck which had been 200 yards back. I rolled onto shoulder with warning lights activated. Pure luck it was not a major accident. Had it fixed at local mechanic in area and was told it is common problem on several makes of vehicles. Mechanic replaced with aluminum one. Gave me a reduced price of $1200.

The contact's daughter owns a 2016 Jeep Grand Cherokee. The contact stated that the vehicle was repaired under previous ownership under NHTSA Campaign Number: 20V699000 (Engine and Engine Cooling); however, the recall repair failed to prevent a recall-related failure 15,000 miles later. The contact stated that while driving at various speeds, there was an abnormal coolant odor entering the cabin of the vehicle. The contact stated that upon further inspection, there was coolant leaking onto the floor. The vehicle was taken to a local dealer and remained with the dealer. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 125,000.

This vehicle has now experienced three separate incidents of sudden loss of propulsion while traveling at highway speeds, requiring it to be towed to the dealership on all three occasions. Each incident involved the same dangerous defect, and after each repair I was assured, the vehicle had been repaired and was safe to operate. Despite those assurances, the identical defect has continued to recur. This is not simply a customer satisfaction issue; it is an ongoing safety issue that places my family and every motorist around us at significant for catastrophic event. On May 12, 2025, I took delivery of my 2025 Jeep Grand Cherokee High Altitude. On June 23, 2025, the vehicle experienced its first sudden loss of propulsion while traveling at highway speed and was towed to Ryan Auto Mall in Buffalo, Minnesota. On January 5, 2026, the identical defect occurred again. The vehicle once again lost propulsion while traveling at highway speed and was towed to the dealership. From January 5, 2026, through May 13, 2026, my vehicle remained at the dealership for approximately four and one-half months while Stellantis and its authorized dealer attempted to diagnose and repair the recurring defect. Following that extended repair process, I was advised that the vehicle had been repaired and that the issue had been resolved. Settlement Agreement: On May 13, 2026, I executed a Release Agreement with FCA US LLC. As part of the negotiated settlement, I was required to enter into a lease for a 2026 Jeep Grand Cherokee. The only reason I agreed to sign the Release Agreement and enter into the new lease was because I relied on Stellantis' representations that the 2025 Jeep had been successfully repaired and that the dangerous defect had been permanently corrected. Had I been informed that the vehicle remained susceptible to the same failure, I would never have agreed to retain the vehicle or execute the related lease agreement.

My 2025 Jeep Grand Cherokee 4xe suffered a catastrophic internal engine failure and set DTC P2338 ("Cylinder 3 Above Knock/Combustion Vibration Sensor Threshold"). Although my VIN is not included in Safety Recall 78C (NHTSA 25V-766), my vehicle experienced the same failure mode, symptoms, and diagnostic code associated with the recall. Stellantis' STAR Center reviewed the case, confirmed internal engine damage, and recommended complete engine replacement. While driving at highway speed, the vehicle suddenly lost power and entered limp mode. I was able to safely exit the highway, but this defect created a serious safety risk and could have resulted in a crash. Stellantis has already expanded the recall population after identifying additional affected vehicles. My vehicle was built during the same production period, experienced the identical failure, and has a manufacturer-confirmed engine replacement recommendation. Chrysler's XC2 program provides unlimited years/unlimited mileage engine coverage for this defect, which is linked to engine manufacturing issues. Based on the identical failure characteristics and confirmed diagnosis, I believe my vehicle is affected by the same defect and should be included in Recall 78C and the associated XC2 warranty coverage. I am submitting this complaint to request that NHTSA investigate whether additional vehicles outside the current recall population are experiencing the same defect and whether Recall 78C should be expanded to include affected vehicles such as mine.

My car started jumping after purchssing it in November 2025 used. The gear would feel like it was slipping. In March 2026 I parked my car turned it off let off the brake and it rolled. I have used the emergency brake since then. The gas gauge is off. The miles and gauge do not line up correctly and I was advised fuel pump may be off. It will drink gas up within a few miles. Check engine light came on without warning. Took it to check it out said oil sensor. He said replace it soon as you can still driveable. The next day i drove to my sons college and the jeep had no power, the check service on the screen popped up. And the jeep would not accelerate. I was anle to take it to O'Reilly and several codes appeared stating 2 gear shift ratio inaccurate 7 gear shift ratio inaccurate, engine oil pressure control circuit performance stuck off, clutch temp threshold achieved auto stick inhibit. The employee said he had never seen these codes populate. He asked if i had smelled any transmission fluid burning. I said no. No leaks nothing. Had the car for 7 months. He stated transmission isnt any good. That I would need a deep decoding done to say for sure. Car is in limp mode now. Unable to drive safely.
