Go to brake and the car will not stop. It will slow down, but the engine will race and will over power the brakes. The car will roll forward and you cannot stop it. This has happened three times since we bought the car in April. The first time I witnessed it happened; we were at a complete stop in line to cross over a toll bridge. He went to move up and the car started to race and he could not stop it. The last time was yesterday as we were coming home. He was slowing down to pull into the driveway. We had spent the day driving all over. As we turned to go into the driveway he said, “Look, it is doing it again.” The engine RPM indicator was pegged at 5 and you could hear the engine racing. He calmly put the car in neutral, which allowed the brakes to grab and then the engine stopped racing.
