2026 Jeep Grand Cherokee L

My wife was driving our 2026 Jeep Grand Cherokee Limited with our child as a passenger on a public roadway. Traffic ahead slowed because another vehicle was turning into a parking area. There was no collision. The Forward Collision Warning/Automatic Emergency Braking system activated unexpectedly and applied the brakes. Immediately afterward, the vehicle appeared to stall or shut off while still in traffic. The instrument cluster displayed a message instructing the driver to press the Stop/Start button to restart the vehicle. The vehicle did not restart immediately and required approximately 10 seconds before it could be restarted. During this event the vehicle lost propulsion in traffic, creating a safety concern. The vehicle had approximately 3,258 miles at the time of the incident. The vehicle is currently at a Jeep dealership for diagnosis. No injuries or crash occurred.

August 9, we were driving home when the vehicle jerked 2-3 times then the engine shut off (while in motion). This happened on a windy backroad with no way to pull over. We were able to restart the vehicle and make it home safely. Contacted Jeep on the 10, they said it was due to a spark plug recall. When driving to the dealership that morning service AWD light turned on, Jeep replaced the spark plugs and stared that fixed the problem. Driving home once picked up and service AWD light turned on again. Dealership is now stating it is the Drivetrain control module.

I purchased my vehicle on Monday, 8-17-2026. While I was driving my car on Friday, 8-21-2026, I heard a loud explosion, which later I discovered the sunroof had shattered! I was the only vehicle on the road at that time! This should not have happened to a new vehicle a week old! The dealership is NOT taking any responsibility at all! This is a factory defect! My insurance should not have to pay for this defective sunroof! I demand a RECALL!

I am reporting a serious safety concern with my 2026 Jeep Grand Cherokee L. The vehicle has emitted an audible warning, the engine has shut off while the vehicle was still moving, and the D drive indicator began flashing and automatically switches to P park. When this occurs, the vehicle loses propulsion and I am only able to coast to a stop. I then have to manually place the vehicle in Park and restart the engine before the transmission will operate normally again. This has occurred with a quick break due to rapid stopping and this has also occurred after making a right turn with no rapid stop. I did include a photo of the message that appears when this happens that states " autopark engaged shifter autocorrect active". I am currently working with the local dealership for diagnosis of the problem.

The car would stall and shut off coming to a stop or slowing down while driving. The shift to park sensor/ indicator would come on , the knob to park lights would flash as well as the emergency brake would be activated and would not allow the vehicle to go back into drive until the vehicle was shut off completely . Twice it almost caused an accident .

Sparl Plug recall on Jeep Grand Cherokee 2026 L Laredo 4x4. While driving my 2026 Jeep Grand Cherokee L Laredo 4x4, the vehicle occasionally jerks/shudders when I shift into Drive and begin moving. The vehicle feels sluggish and does not respond smoothly when accelerating. This has happened even after the vehicle has been running for several minutes. The vehicle is new, and I am concerned that this may be related to a powertrain or transmission problem.

I purchased a brand‑new 2026 Jeep in June 2026. Shortly after taking ownership, I began experiencing significant condensation and visible water buildup inside the tail lights. This is not minor moisture — there is standing water and heavy fogging that I have documented with clear, detailed photos. Despite providing this evidence, the dealership refuses to replace the tail lights, stating they “cannot duplicate the issue.” The water intrusion is recurring, and I have multiple documented instances showing the defect. Their refusal to address the problem leaves me with a vehicle that may have compromised lighting performance, electrical risk, and reduced rear‑visibility safety, especially during braking or nighttime driving. This is a new 2026 vehicle with a clear manufacturing defect that should be covered under warranty. Water intrusion in lighting assemblies is a known safety hazard, and the dealer’s refusal to repair or replace the defective components puts me at risk. I am requesting NHTSA review this issue, as it appears to be a defect affecting the safety and reliability of the vehicle’s lighting system. Thank You

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.

Vehicle is very jerky while transmission is downshifting. With no pressure applied to gas pedal vehicle lurches forward on own forcing me to step on brakes to correct lunging forward. At parking lot speeds and while in reverse vehicle is very sluggish and feels like stalling will occur if pressure is not applied to gas pedal. Vehicle is also sluggish and does not respond right away while entering highway , there is a delay with acceleration , this also could cause an accident as the vehicle is not speeding up correctly.
