In my neighborhood approaching a stop sign about 20 yards away. The car all of a sudden accelerated at a high rate of speed. I was going too fast to make the right turn and the brakes did not stop the car. I ended up running through the stop sign up an incline and into the woods hitting multiple trees before coming to a stop. This caused over $18,000 damage to the vehicle (not including damage to the under carriage). Not only was this pretty frightening but what could have happened if I wasn't in my neighborhood when this took place could have killed somebody. It really shook me up. Thank goodness there were no kids at the bus stop. I was also surprised that the air bags did not deploy. The insurance company totaled the car so no one really seems too concerned about the cause of the unintended acceleration that totaled my car while driving in my own neighborhood! this should not have happened. I hope someone will care enough to try and determine what happened so this doesn't happen to someone else.

I was in a collision in which I rear ended another SUV. The speed control did not enable and I hit the other vehicle hard enough to cause $20,000 worth of damage to my car. I believe the car braking response was slow and the airbag should have deployed in a crash that significant, but it did not.

The vehicle sensors all started flashing, including the stability control system, parking brake, temperature gauge, etc. The speedometer fluctuated wildly, the car would not shift out of drive and would not shut off. I was trapped in the vehicle, unable to shift the car out of gear into park or neutral and the car would not shut off. I had to keep my foot on the brake, but I obviously could not get out of the car while it was in gear and running. After about 3 minutes of trying to get the car into park I was able to turn off the engine. It was extremely scary. This vehicle is unsafe.
