I was dropping my husband off at cardiac rehab. I was stopped and had my foot on the brake suddenly the car launched forward into the back of a car parked in front of me. The other driver got out of the car and said he wasn't hurt. We were able to drive the car home stopping 3 times to pull pieces of the car off that were dragging on the road. We took the car to a mechanic at the end of the road. He scanned the codes for us. Pre-collision 2 ClAll ; Intuitive Park Assist ClAll Front Sensor Comm. Circuit ; Front Recognition Camera ClAll ; Lane Keeping Assist ClAll Front Radar Sensor Incorrect Axial Gap ; BCM B124B Light Source Sensor Open/Short. The insurance adjustor totaled the car and they picked it up today. No warning lights showed up on the dash until after the accident.
While vehicle was being driven into the garage the vehicle suddenly accelerated on it own without driver pushing on gas pedal. Vehicles automatic emergency braking did not engage. Vehicle then struck steel shelving and wooden cupboards causing considerable damage to vehicle. The body shop where the vehicle was taken for repair experienced the same surging phenomena when they moved the vehicle. There were no system warning lamps visible prior to the episode. The vehicle has not been inspected by Lexus.
Vehicle has been reported before for similar problems. This time, no power, severe stumbling, lurching. Check engine light comes on along with warning indicators that the electrical systems have failed. Lexus notified again and vehicle will be towed to dealership. This car is dangerous and life threatening as we were in traffic with no power. Dealer did not notify us of any problems prior to sale but this car qualifies as a lemon under AZ law. Additionally, if other Lexus owners are having this problem, they should immediately stop using the vehicle and park it before someone gets injured/killed.
