NHTSA Complaint #11567173 — 2013 FORD EXPLORER

Driving on a two lane highway with the cruise control set, tapped brake to eliminate the cruise as a truck had pulled onto highway ahead of us. Accelerated to pass the truck and resumed the cruise control to maintain previous speed. The vehicle began increasing speed as if the gas pedal was floored. Tapping brakes didn’t stop it nor did shutting the cruise off on the steering wheel, car was going 80-90 mph. Had to ride the brakes while the throttle seemed to be wide open until we could get it in neutral and pull of on the shoulder. Restarted the vehicle after it was shut off and the throttle was wide open again. The third time I started it, it appeared to be running normal. I did not engage the cruise control after that. At the time there was no engine light or warning light on. About a week later the engine light came on then a couple days later it was not on. Then it randomly would come on. I had scheduled an appt and it was determined the throttle body, gasket and purge valve needed replaced. This was an extremely scary situation and I would like to know if this has been an issue and could it possibly happen again? This could’ve caused a serious accident when you have zero control of the speed and it’s approaching 90mph on a highway. I did get repairs that were an expense over $500. Is there an explanation as to why this happened and can it randomly occur again??
