While entering a business park's parking lot, my vehicle suddenly and immediately stopped all forward movement. I was thrown against the steering wheel, injuring the right side of my chest and scraping the skin off my right forearm which was covered with the sleeve of my shirt. I was dazed, had no idea what happened, and thought that I had hit something but yet no airbags had deployed. When the vehicle stopped it was near a light post which I assumed I had hit. Upon exiting the vehicle I noticed the front tire was blown and the wheel was sitting on the ground at an odd angle. Walking around the vehicle showed no other body damage other that a few small strips of yellow paint from the base of the light post. When the tow truck driver was placing the chains to load it onto the flatbed, he called my attention to the fact that the drivers side control arm had failed. See the attached pictures for further detail. I am very grateful that I was not in traffic on a major highway as this would have been a horrific accident. Pictures show the control arm had a crack with exposed rust on edges of a fracture in the control arm. This vehicle has only been serviced at Toyota authorized dealerships and has undergone their multipoint inspections during these visits that include the front and rear suspension. I will not feel comfortable driving this vehicle again!
