NHTSA Complaint #11546178 — 2015 FORD F-150

During normal highway driving, the vehicle abruptly went into "limp mode" with a complete loss of throttle control. The engine remained running, but I was unable to increase the speed of the vehicle. Once stopped, the vehicle showed several alerts on the dashboard: "Service Advancetrac," "Hill Assist Not Available," and "See Owners Manual." I was able to scan for fault codes and returned DTC P2112: Throttle Actuator Control System Stuck Closed. Upon further research, there is a Ford Technical Service Bulletin # TSB 16-0193 which states the vehicle may exhibit an intermittent loss of power and/or an illuminated powertrain malfunction (wrench) lamp with diagnostic trouble codes (DTCs) P2111, P2112 and/or P2119 stored in powertrain control module (PCM) memory." After restarting the vehicle, it returned to normal operation with the dashboard errors remaining. A Ford dealer is scheduled to look at the vehicle. I have been told they expect to diagnose and replace a faulty Electronic Throttle Body. Losing complete throttle control while driving on a busy highway is dangerous for many obvious reasons.
