What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
There were no warning lights illuminated. A Police report was filed. The vehicle was towed to a tow lot. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted and suggested that the vehicle be towed to the dealer. A claim was filed with the insurance company.
Computer telling vehicle to do a sudden unintended acceleration. Forward collision warning system did not respond. Air bags didn’t deploy. No diagnostics have been done. No warning lamps illuminated on dash. Vehicle currently is at repair shop.
The contact stated that while driving at slow speeds in stop-and-go traffic, the vehicle inadvertently accelerated on its own. As a result, the contact briefly lost control of the vehicle and collided with the rear of the vehicle ahead.
The contact stated that while driving, the A/C blew alternately through the vents directed toward the contact and through the defrost vents. The contact stated that the A/C failed to blow air through both vents simultaneously, and the air was unintentionally hot or cold.
Odometer is flashing, climate control on the touch screen says 'Climate off'. This is the 5th repair attempt for this vehicle.
2023 Jeep Grand Cherokee Summit unexpectedly applied the brakes while traveling approximately 78 mph with Adaptive Cruise Control engaged. There was no vehicle, object, or obstruction directly ahead. The forward collision/ACC warning activated immediately before the vehicle braked.
The contact stated that while driving 20 MPH, the headlight high beams failed to automatically activate as designed. The vehicle was taken to a local dealer where it was diagnosed, and the contact was informed that the automatic high/low beam activation system was inoperable.
We were accelerating from a stop light and reached about 50 mph when the brakes activated and large red letters saying “BRAKE” were displayed on the drivers dash screen and an alarm sounded. The vehicle slowed rapidly and suddenly. Fortunately we were around no other traffic so there was no collision.
