While driving 25-30 mph rpms went up and vehicle started to accelerate. Consumer applied brake, then shifted to neutral. Rpms then went to 45000. Consumer applied brakes to slow down vehicle. Dealer could not find cause. This happened a second time on July 23, 2002. The problem of vehicle accelerating when brake was applied occurred again but the dealer was unable to find the cause.
