My Lexus 2012 Is 250 accelerated on its own, brakes did not engage after depressing them X2, and then I crashed into a truck. Air bag did not deploy. Reported to Lexus who assumed no responsibility for incident. Third party inspected car and downloaded black box. Report from Lexus stated that car was drive able and no issues were found. Car incurred $18,000 in damages and was not drivable at the time of inspection. Witnesses at collision shop will validate such. When speaking to representatives at Lexus to report incident I was told by 2 reps on 2 occasions that this has happened to other vehicles that were the same make and model. Disturbing
