One problem related to accelerator stuck has been reported for the 2005 Subaru Forester. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2005 Subaru Forester based on all problems reported for the 2005 Forester.
When it is below 30 degrees out and heater or defroster is on and the vehicle is moving between 25-65 mph, the accelerator sticks and does not decelerate. When the clutch is applied to disengage the engine the rpms advance 1,000 to 1,500 rpms(sometime taking the rpms to 4,500 rpms). Vehicle has no engine warning lights on the dashboard and no error codes on the ecu. The maf, map and pcv sensors are all function correctly. The throttle body is also perfectly cleaned. Vehicle idols fine and passes all emissions tests. I have been informed that the drive-by-wire (dbw) mechanism is most likely the problem and this component should be replaced.
