| Description of the problem | Uncontrolled acceleration where depressing the brake pedal was "soft" and did not have any effect in stopping the vehicle. I was pulling into my garage and as i neared the point where i wanted to stop, i pressed on the brake pedal. This had no effect and the vehicle continued to accelerate. The vehicle proceeded through the other end of the garage. There is a drop from the floor of the garage to the ground on the back side of the garage. When the heavy front end of the 2010 toyota sienna went through the garage wall, it dropped to the ground and the vehicle was balanced like on a teeter-totter with 1 rear wheel in the air instead of on the garage floor. This position stopped the vehicle from continuing to move forward. I was unable to get out because the doors were locked and did not release when i tried to open the door. I called the local security force who came to my assistance. With the security force pulling on the door from the outside, i was able to get out through the rear passenger door. This has never happened before but the consequence was frightening even at the slow speed that i was going. I contacted my insurance company and though not finalized, it appears that they believe they would be able to repair the vehicle. Their repairs would be body work, painting, and a new front windshield. My concern is that these repairs may not address the root cause of the problem - that the brake pedal did not slow or stop the vehicle as intended. |
