Owner complaint summary

Will driving on the interstate, using the adaptive cruise control feature, vehicles were slowing down to a stop ahead and my car accelerated instead of slowing down. I then pressed the brake and simultaneously, the car breaks locked down (automatic braking). Unfortunately I wasn’t able to avoid an accident as I rear ended the vehicle in front of me. My vehicle has been turned over to the insurance company to assess damage. I’m sure it can be inspected by nhtsa. Mine and others safety were at risk due to the malfunction of the cruise control accelerating instead of stopping. It caused an accident. Luckily no one was extremely injured. I have neck and back pain from the collision that will hopefully heal in a few days. Time will tell. But this could have been much worse had I not reacted as quickly as I did. This could cause a fatal accident. The care isn’t drivable so it has not been reproduced by anyone. I have notified the insurance company about the issue and It is my hope that they will inspect this. There were no warning lights or messages displayed prior to the incident.
