Took my 05 Legacy GT to get diagnosed to find out why. Was told a load of BS. Had to take it to a Master Certified Subaru mechanic who diagnosed it had a clogged up pipe. Because, it was misdiagnosed It fried my exhaust valve and killed my motor. $4000 to rebuild it. I just want Subaru to do better on diagnostics so this doesn't happen to anyone else. Misdiagnosed by Mid Hudson Subaru of Wappingers Falls NY, 12601.
