| Description of the problem | Tl* the contact owns a 2004 subaru legacy. The contact was driving approximately 30 mph when the vehicle decelerated independently. The check engine warning light was illuminated as the cruise control warning light began flashing. In addition, the vehicle would not accelerate over 10 mph. The vehicle was taken to the dealer for diagnostic testing where the technician advised that the throttle position sensor would have to be replaced. The vehicle was repaired however, the failure recurred six times. The throttle was replaced twice. The electronic control module was replaced and the manufacturer was made aware of the failure. The vehicle was not repaired. The approximate failure mileage was 20,000. The consumer stated the throttle ceased to function normally and the check engine light illuminated. The vehicle, would then slow down immediately and would only move at a speed of approximately 10 mph. The consumer stated he learned if he came to a full stop and restarted the vehicle three or four times, the throttle would re-engage and he would be able to resume normal speed, sometimes for some distance , and other times for only a short distance before it failed again. When the vehicle's electronic control module was checked by a mechanic, it showed a code p2138. It appeared that the engine computer unit was involved because when it rest the throttle worked again, briefly. The mechanic reset and it ran normally for three days before failing.
