One problem related to car throttle stuck has been reported for the 2010 Ford Focus. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2010 Ford Focus based on all problems reported for the 2010 Focus.
Experiencing rough idle and complete loss of power at normal speed, engine check and wrench light comes on at time of issue. Had a diagnostic check at advance auto and error code p2135 throttle position sensor/switch a/b voltage correlation and also error code p2111 throttle actuator control system stuck open. I believe this to be a safety issue due to complete lose of power at normal driving speed and just enough time to pull over or almost getting hit from behind.
