Open the full vehicle complaint log (all categories)After 45 minutes in stop-and-go traffic the brake pedal went to the floor four times, the Brake Override System (BOS) failed, throwing the shifter into Park failed, and we hit the car in front of us. No warning sounds typical for this car sounded and no lights appeared on the dash. Thankfully, we were only moving at 5 mph which I didn't think qualified as a "crash" but there was indeed a collision. No one was hurt. Besides my wife and myself there were two backseat passengers who also saw my efforts to stop the car. We had the car towed to Lexus of Santa Monica. Unsurprisingly, Ronald Inton with Toyota Motor North America, Inc. (TMNA) indicated in his letter to us that Lexus inspectors seeing our crumpled front license plate and knowing of the failure of the BOS found nothing wrong with the car, but had not driven it under stop-and-go conditions for 45 minutes as we had. The clear failure of the BOS to prevent the collision or even warn of the impending collision was effectively ignored my Mr. Inton. Our full correspondence with him is attached. Both my wife and I loved driving this car but it is a potentially deadly safety hazard and given that TMNA can't fix it, should be destroyed.
