2011 Subaru Forester Cruise Control Problems

Your car has experienced sudden, unintended backward acceleration without any driver input or warning. This has happened twice—once in a parking lot and once backing onto a major road—causing your car to accelerate rapidly in reverse, cross multiple lanes, and hit property. The issue appears to be a defect in the vehicle speed control system that could cause serious injury or death if another vehicle is in the path.

Your car suddenly accelerated to full throttle without any pressure on the gas pedal while driving slowly in city traffic, causing it to collide with the truck in front of you. Even slamming the brakes and pulling the hand brake were not able to stop the unexpected acceleration. This type of sudden unintended acceleration is a serious safety issue that requires immediate diagnosis of the fuel injection system, throttle control, and brake system.

While driving uphill with cruise control active, your car's transmission shifts down aggressively, causing the engine to rev high. When this happens, your check engine light, traction control light, and blinking cruise control light come on — and your accelerator stops responding entirely, even when pressed all the way down. This happened twice during mountain driving and created a dangerous situation where the car rapidly decelerated on a steep road. After turning the car off and back on, the issue temporarily stops. A diagnostic scan revealed code P2138, pointing to a throttle pedal position sensor problem. The fix will likely involve inspecting or replacing the throttle pedal position sensor and its associated wiring.
