“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”

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.)”
