Jeep Grand Cherokee L key fob problems

Filed Aug 13, 2026 · Engine · AL

Vehicle: 2026 Jeep Grand Cherokee L Limited Location: [XXX] Safety Issue Description: When using the remote auto‑start with the key fob, the engine starts briefly and then shuts off. When the vehicle is manually started, the check‑engine light immediately illuminates and begins flashing, and the vehicle jerks violently even while in park. The flashing check‑engine light indicates an active engine misfire, which poses a significant safety risk due to potential engine stalling, sudden loss of power, and potential catalytic‑converter damage.

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.

Infotainment system glitch Screen blacks out Auto start/stop doesn’t work Key fobs glitch Vehicle jerks (I’m guessing it’s sensing something that isn’t there, but no one seems to know) Doors unlock themselves Alerts “key fob not detected” while driving and while parked

My vehicle wasn’t reading my key fob when I was pressing the lock and unlock button, so I took out the hard key and unlock the doors. Then the alarm set off and I was using the key fob again trying to shut the alarm off no response so I took the key fob and press the start stop button and the engine turn over and the key was working again then I went to shut off the engine same way. The engine would not shut off my driver seat wouldn’t move so I couldn’t get to the battery and I paid a lock smith to come out and he couldn’t even help me with my key fob not syncing with the vehicle..my ebreak would not release or the emergency override break wasn’t working. On the digital dash it’s kept saying shift to park to release parking break but the vehicle was in park all while doing so. This all happened around 7pm. So I could not get help until the morning cs the vehicle would not move

The Uconnect infotainment system is glitchy, blacks out, and has restarted itself. The dealership I purchased it from has currently had now for a 3rd time and over 30 days. The 2nd visit the screen was replaced and the same issues still exist. This is a huge safety concern, because the system has malfunctioned while in reverse which obstructs the rearview camera view. I can’t trust that rear sensors aren’t tied into this and will apply the brakes if I get too close to something or someone/something suddenly goes behind me in reverse. The blind spot monitoring system has gone out a few times and this limits the lane keep assist functions. The dealership has said they can’t replicate the issue and the first time this happened no codes came up despite there being a stored message on digital cluster display. They have replaced a sensor module this time, but as they still have the vehicle I don’t know if this has fixed the problem or not. This is obviously a huge safety issue as it could case a wreck if someone is in a blind spot and I can’t see them and the vehicle can’t help alert me to this. It also seemed to slightly impact the handling of the vehicle as well causing me to consistently need to make micro adjustments of the steering while driving. Among those issues I have been having other commonly known issues with vehicle such as the “key fob has left vehicle” message despite the key fob still being inside the vehicle. It does not matter which key fob is used and the battery to the fob is good. The dealership can’t four that out either and have checked to make sure the serial numbers on the fobs match the VIN. The fan speed pop-up when shutting off the vehicle displaying 127 front/0 rear can’t be figured out either and dealership verified it has the most updated software versions currently available. A lot of these issues have been there since I purchased it 12/2025 or showed up within 1-2 months of owning it. Finally took it to the dealership in March.

Active Lane Management disengages itself upon start up. Sometimes says needs servicing - message disappears upon car restarting. Car states key fob is not in vehicle when it is. Car has turned on, not shifted into gear, and then not been able to be turned off. Steering input from the system is sudden and does not consistently match actual road conditions Radio screen flashes/goes black/freezes Emergency Assisted Braking system activates without a clear obstacle present Braking events are abrupt and unexpected during normal driving Both systems operate intermittently and without a consistent pattern, making the behavior unreliable Dealership has been unsuccessful in reproducing any of these problems despite picture proof provided. Has happened on multiple occasions - beginning in September 2025. Jeep/Stellantis unwilling to resolve. Safety Risk: The unexpected steering corrections and sudden braking create a risk of loss of vehicle control and increase the likelihood of a rear-end collision or other traffic incident. These safety systems are not functioning as intended and instead introduce unpredictable and potentially dangerous vehicle behavior.

I purchased my 2025 Jeep Grand Cherokee, new, approximately one month ago on [XXX] at Victory CDJR in Merrillville, IN 46410. Since purchase, the vehicle has been returned to the dealership three times for the same issue, and I am now scheduled for a fourth repair attempt. This fourth repair appointment was scheduled on the same day of the 3rd attempt hours after I picked it up because the problem wasn't resolved. The problem is that both key fobs randomly stop working, preventing reliable access to and operation of the vehicle. The failure is intermittent and unpredictable, which makes it especially concerning. Despite multiple service visits on November 26th, 2025, December 3rd, 2025, and December 31st, 2025, the issue has not been resolved and I now have to return the fourth time on January, 2nd, 2026. The dealership is never able to recreate the issue when they have the vehicle in their possession, but I have taken video of both key fobs not working and have tried to show them when I take the car in and they don't seem very interested in seeing the videos. There are no warnings to signal me of when the fobs will stop working because it is random. The first time this issue occurred was 2 days after I purchased the car on [XXX].

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.
