Takata recall - my air bag never deployed on impact. As I was braking to park outside my garage door, the car suddenly accelerated extremely fast. My Lexus went through the garage door and I was braking but my SUV didn't stop until it hit things in the garage that stopped me. I even plowed into a piece of equipment that went out the back wall of the garage

The contact owns a 2009 Lexus RX350. While depressing the brake pedal at 5 mph, the vehicle accelerated without warning, went over a curb, and down a 7-8 foot steep embankment and over a high curb at the top. As a result, the contact crashed the vehicle into a parked vehicle and then rolled backwards. The air bags failed to deploy. There were no injuries and a police report was not filed. The vehicle was taken to a dealer, but was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 56,000. Updated 08/05/16 updated 08/15/16.

The contact owns a 2009 Lexus rx 350. The contact was driving at a low speed while driving into a parking space, when the vehicle suddenly accelerated and drove over the curb. She attempted to use the brakes which did not work at first to stop the vehicle. She then depressed the brake pedal with extreme force and shifted into park which stopped the vehicle before it could collide with a plate glass window. The vehicle previously had slight acceleration problems but when speaking to the dealer in January, the dealer stated that there was nothing wrong with it. The vehicle was towed to an authorized dealership where the vehicle was at the time of the complaint. The dealer stated that the manufacturer would send a representative out to inspect the vehicle. The current and failure mileages were approximately 32,000-bk

I was driving my 2009 Lexus rx 350 at about 25 miles per hour when it suddenly rapidly accelerated. Fortunately there was nothing/no car immediately in front of me. I pressed down on the brakes and the car responded by slowing down. I have reported the incident to Lexus and will have the dealer inspect the car as soon as possible. (they gave me an appointment in 2 days.)

RX 350 6-cyl

  • 4,500 miles
The contact owns a 2009 Lexus RX350. While pulling into an off-street parking space at speeds of less than 5 mph, the vehicles engine began to surge and the vehicle then abnormally accelerated. The contact attempted to depress the brake pedal, however the brakes were non-responsive. The vehicle then crashed head on into a stone wall. The vehicle was able to be driven from the crash site. She then drove to her local dealer. The dealer did a short visual inspection and stated there was nothing wrong with the vehicle and that driver error was the cause of the crash. A diagnostic was not performed on the vehicle. Repairs to the vehicle were made. There were no additional failures following the repairs. She stated that following the repairs, the accelerator pedal felt higher and as if there were modifications done on the vehicle, however she could not prove what repairs were done. The failure mileage was 4,500 and the current was approximately 7,500. Updated 4/28/10 updated 07/01/10.
