In parking garage, turning into parking spot. Car engine revved up, and car accelerated into the guard rail, smashing the frontend of the vehicle and damaging the radiator. Driver did not put foot on the gas; car lunged forward on it's own. The airbag deployed, and driver had dark bruises on abdomen, left anterior thigh, and left side of neck d/t seat belt, and also had minor whiplash. Fortunately, no other cars or people were around when car accelerated. Also, had the car had more than just a few feet to run into something, the driver would have been injured worse. Prior to incident, car engine revved up for several seconds on its own twice while driving down the highway.

I am the original owner of this vehicle, purchased brand new. In January 2012 the heater when turning on made a loud clicking sound for approx. 20 to 30 seconds, each time. Upon research on the internet, local mechanics, I found out the heater blend door actuator is the problem. I was going to replace it, but upon further investigation I found that this heater assembly is not only used by Mazda, Nissan, Toyota, chevy, Ford, and Lexus. This heater is known to have this design error. I then decided to have the Mazda dealer change it for $130. 00. The dealer then told me the whole assembly needed changing for $250. 00 plus labor. This assembly was known for this. Also the dealer had unplugged the heater blend door actuator because this unit is known to start a fire in the vehicle. This made me extremely nervous. I consider this to be an unsafe vehicle.
