2025 Jeep Grand Cherokee L Powertrain (other) Problems

The occurrence happened 4 times. While driving when the accelerator is pushed, and not in an extreme way, the engine will rev to the maximum level, the transmission stopped working the car comes to a slow stop and the ignition must be switched off to stop the run away engine. Then restarted without incident. This has happened while making both left and right turns with and without cruise control on. Example: while driving on a 2 lane road with cruse control on the car in front slows to turn I apply the brakes, when applying minimal pressure to the accelerator pedal the engine revs to redline, the transmission stopes functioning and the vehicle coasts to a stop while in traffic with no forward movement possible. The engine revs without any input from the operator. Very dangerous have almost been rear ended 4 times by the traffic behind me. I feel this is a serious problem that may cause a serious life threatening accident. I will be requesting repair or replacement from the dealership under warranty and will report any findings to this organization. This needs to be addressed immediately as this is a serious life threatening issue.

I am reporting recurring safety-related shifting and vehicle gear/park-state concerns involving my 2025 Jeep Grand Cherokee L Summit Reserve. On multiple occasions, the vehicle has failed to transition properly from Reverse into Drive. I reported this Reverse-to-Drive issue to the manufacturer before later becoming aware of diagnostic information that I believed could potentially relate to the behavior. I am not a mechanic and do not know the underlying cause. On July 5, 2026, while my infant was in the vehicle, I placed the vehicle in Park and it displayed a “Park Not Engaged” warning despite being in Park. Warning sounds occurred and the vehicle automatically engaged the parking brake. This caused me serious concern about whether the vehicle was reliably recognizing its selected gear/park state. I immediately reported the incident to the manufacturer and was instructed to bring the vehicle to an authorized dealership. I complied. The vehicle was at the dealership from July 8 through July 27, 2026. During that repair visit, the dealer documented that FCA/WiTECH diagnostic systems were unavailable and that the vehicle could not be properly scanned. The vehicle was ultimately returned to me without the reported concerns being resolved. The vehicle has accumulated approximately 22 days out of service during its repair history. The manufacturer and authorized dealership have been made aware of my concerns and the vehicle has been available for inspection and diagnosis. I remain concerned about the recurring Reverse-to-Drive behavior and the July 5 Park Not Engaged event because unexpected or unreliable gear/park-state behavior could create a risk of unintended vehicle movement or an inability to reliably control the vehicle as expected. The underlying failed component or cause is UNKNOWN. I am submitting this complaint so these incidents are documented and can be evaluated by NHTSA for a potential safety-related defect.

I was leaving a light and turning left onto incoming traffic Columbia and John young parkway. Vehicle turned off with no option of turning back on . I rolled onto the right curb but was sticking my vehicle out. Me and my wife and teenage son. Feared for our life due to the car not turning on and incoming traffic . This is a serious issue and hazard. The car asked me to put the car in park. After I did that the car would not turn on. Called SOS and Assist. We had Roadside coming 45 min later.There was a high pitched sound coming from the engine compartment . The car would not turn off at all. The Push Start Button would not turn the vehicle off or on. The Round buttons for D/N would not turn at all. The Tow truck driver use a red pull handle and put the transmission in neutral. It’s a release that was on the driver side pillar of the vehicle. After we arrived to Napleton Jeep the car immediately turned on. Our biggest safety concern is that this would’ve happened on a highway and my wife would not know how to react resulting in an accident or fatality. This is an issue that never in our 30 Years of experience we had with any of our vehicle brands. I wish the National Highway Safety Administration take measures to Jeep and investigate this matter. Thank you for your time

My vehicle is experiencing multiple dangerous electrical and drivetrain failures that occur intermittently and without warning. The issues began the day of purchase purchase and continue to worsen. Documented defects include: Vehicle randomly will not start Vehicle randomly will not turn off Dashboard/electronic systems reset intermittently (gauges go blank or restart, Bluetooth disconnects, warning indicators reset) Fuel gauge does not update while driving Sometimes vehicle will start but will not move (forward) when shifted into Drive or when in drive and brake pedal has been depressed. Vehicle sometimes fails to move when placed into Reverse Vehicle must be shut off and restarted to regain ability to move Key fob is not recognized by the doors or proximity sensors Driver’s seat creaks and feels unstable during acceleration Tire pressure sensor malfunction All systems intermittently disconnect/reset at the same time (suggesting a body control module or CAN-bus failure) Safety Concerns: The vehicle has refused to move in traffic, including while sitting in a drive-through line. The vehicle has failed to start in multiple public locations. The vehicle has failed to turn OFF, requiring multiple attempts. Loss of instrument cluster information could be very dangerous and matches symptoms currently under federal investigation for similar Jeep models (instrument panel cluster failures). These failures clearly impair the vehicle’s use, value, and safety, and appear to be part of a widespread electrical defect affecting Jeep products. A Jeep dealership confirms the issues and has scheduled service, but the problems continue to multiply. There are currently no open recalls for my VIN, although the symptoms match the national Jeep cluster/electrical investigation. I am submitting this complaint because these failures pose a serious danger to myself and other drivers + won't start. Please investigate this as a potential electrical/BCM/IPC/CAN-bus defect.

Within weeks of purchasing my brand-new 2025 Jeep Grand Cherokee, this past Thursday when leaving for my workday the steering wheel on my vehicle became completely immovable when I attempted to leave. I started the vehicle and tried to turn the wheel, but it would not move at all. There were no warning lights or alerts. I had no ability to steer or maneuver the vehicle, and it was completely undriveable. The vehicle had to be towed from my workplace to the dealership because the steering would not turn. After diagnosis, the dealer informed me that the entire power steering rack had failed and required full replacement. A power steering rack is a critical safety component, and a failure of this magnitude on a brand-new, very low-mileage vehicle is extremely concerning. If this defect had occurred while driving, it could have led to a total loss of steering control and a serious crash. I no longer feel safe operating this vehicle. I am requesting that NHTSA record this incident as a safety-critical steering system failure and investigate whether similar power-steering or steering-rack failures may be occurring in other 2025 Jeep Grand Cherokees.

Vehicle shuts off intermittently without warning. Random dash warning lights will flash, but not stay on. Air suspension will engage on its own while vehicle is not turned on, and electrical panels and lights will turn on and flash while vehicle is parked in garage, hours or days after last driven. Transmission will struggle to shift gears from low speeds, but then quickly “catch up” causing unpredictable acceleration. This vehicle has been to the dealership 5 times with batteries replaced, and software resets done, but no conclusion to what the source of the issue is. A camera was installed in our garage after the vehicle was sent home with us without being repaired due to being unable to replicate the issue. The camera captured 4 incidents of the vehicle electronics turning on, and air suspension raising up and down over a span of 5 days. We were advised to park the vehicle outside of our garage for fear of potential electrical fire, or it starting on its own. The vehicle is currently still in the dealership service department as they try to find the source of the issue. The vehicles electrical malfunctions have caused it to shut off on the highway, and while backing out of our driveway on multiple occasions. This puts both driver, occupants, and other drivers on the road at risk of being involved in a collision. The issues with the vehicle struggling to shift gears, and then “catching up” like a computer glitch, and accelerating unpredictably has been dangerous during merging into traffic.
