“My wife and I had returned to the car after shopping. I started the car and drove to the first stop sign. We were on city streets in the town of nashville indiana. The car was normal. I went to the next stop sign and the car also acted normal. As I approached the third stop sign and was applying the brake the car started accelerating. The loud engine noise was also noticed by my wife. I said something is wrong with the car, the engine is racing all by itself while I am trying to brake the vehicle. …”

“I was driving up the hill & slowed down for the speedbump. I started applying the brakes to turn right into the driveway but the car lunged forward, causing me to miss the driveway & turn into the yard. As I stepped on the brake the car continued to speed up so I screamed at my husband james I can't stop the car! He yanked the handbrake up but it didn't stop or slow down and the engine made a continuous high pitched racing sound. We crashed into the house, damaging it & breaking my left arm! The car was totaled. All this occurred in just a matter of seconds. …”
