While in gear the throttle has accelerated uncontrollably without a foot on the pedal. It has happened twice now and both times resulted in significant damage. Applying the brake made no difference they were just overpowered by the motor. The vehicle is going to be towed to a body shop to get a repair estimate. Last time the damage was about $14,000. The vehicle is not safe if you cannot control the speed. They thought last time my foot slipped of the brake onto the throttle but I said no it had not. I was to busy trying to control the truck to notice if any warning lights went on. However earlier in the day the cruise control would not turn on.
