Adaptive Cruise Control problems of the 2017 Jeep Grand Cherokee

This is sonia clark. On September 14, 2023 had a very big crash with our 2017 Jeep Grand Cherokee. My husband and granddaughter were in the crash. Everyone is okay but the Jeep is totaled. At 7:00am, the Jeep accelerated out of control, my husband was trying applying the breaks, but the accelerator over powered the brake system. The car reached speeds of between 74-83 mph based on the life 360 app our both my husband and granddaughter have on their phones. This occurred in downtown lebanon ky during the morning school hours. He was unable to stop or slow down the Jeep. It resulted in him running through 2 red lights and 2 4 way stops. He also had to avoid hitting several cars and pedestrians including children. Finally the Jeep skidded to the right of the road and hit a telephone pole, a bridge guard rail where the front passenger side tire was torn off, and went up an embankment and hit a tree. The police at the scene estimated the car hit the tree about approximately 50 mph. No airbags deployed and of course the car is totaled. Our daughter drives our other 2015 Jeep Grand Cherokee and had the same issue a week before this happened but she was on an open road and was able to use the paddles on the steering wheel to disengage the cruise control and get the car under control. Jeep is saying that there is no recall so we will have to pay for the 2015 to be looked at. Of course we are going to do that immediately. The dealer has engaged a 3rd party from bosch to retrieve the data from the cars computer system but that has not happened yet. There were no warning lights on, the vehicle is awaiting Chrysler's inspection. The insurance company deemed the vehicle a total loss based on the photos we sent them. The police inspected the car after the accident. We have all the service records for both Jeeps.

The contact owns a 2017 Jeep Grand Cherokee. The contact stated that while driving approximately 55 mph with the adaptive cruise control activated the vehicle nearly crashed into the rear of a second vehicle. The contact indicated that the adaptive cruise control did not reduce the speed as needed. The cause of the failure was not yet determined. The manufacturer and local dealer was notified and indicated that a software update of the adaptive cruise control was needed. The vehicle was not yet repaired. The failure mileage was 93,000.
