Well, if the engine is in cruise control at 75 mph plus or less and you step on the gas pedal the engine ROARS and Accelerates up to 4k rpm, my vehicle had accelerated to 90 mph but depressing the cruise control off button does nothing to stop the acceleration, stepping and continuous pressure on the brake does not stop the acceleration either. I had to turn the ignition off and pull over, waited up to an hour to be able to restart vehicle. This issue has occurred several times. Now I no longer use the cruise control. I'm po'd. This problem is liable for someone's death. thanks
