2026 Jeep Grand Cherokee L Problems

While attempting to execute a left-hand turn across oncoming traffic, the vehicle suffered a severe and sudden throttle hesitation and loss of acceleration power. Despite applying pressure to the gas pedal, the vehicle failed to accelerate quickly enough to safely clear the intersection, creating an immediate, life-threatening safety hazard with oncoming traffic. There was about a 6-second delay and this kept happening. Following the hesitation, the vehicle accelerated painfully slowly. Prior to this incident, a heavier rumble or rough idle was noted upon engine startup. There was no Check Engine Light or warning message displayed on the dashboard. Bypassing the issue via Sport Mode was unsuccessful. This is a brand-new vehicle leased only two weeks ago. I am fearful to drive it at this point.

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.

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.

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

I was stuck on the Hot way for 45 minutes cause my car was heating up. It’s been in shop four times for heating up on the fourth time I took it in. I was stocked because my electrical started going out. The speedometer started just going around my electrical on my dash started going from heat to cold my seat controls then it started of the dash panel are going to ABS and going to different things showing the speedometer showing the mileage on the car it just started doing its own controls so and then my speedometer just called going fast and went back to deal so and didn’t blacked out so I videotaped everything

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!
