135000 mi

Leaky valve covers (both sides) 
44000 mi Blown turbo due to clogged oil filter on line leading to turbo. Apparently common problem on the 2005 Legacy GT's. Replacing unit with aftermarket turbo. 
20000 mi Black sooty buildup at exhaust pipe tips. Dealer said this is normal. Our other car, with a turbocharged engine alos, does not have any evidence of soot at the tail pipe. After driving ~ 15-20 minutes to get to interstate, exhaust smokes so you can't see out the rearview mirror accelerating onto the freeway in cold weather. Dealer says this is normal. Car hesitates or misses, occaisionally when driving 35-40 mph in 3rd gear, cruise on or not. They reflashed the engine contol module. It helped decrease the frequency, but did not eliminate the problem. 
42000 mi

US $176
OBD reported "system too lean", inspected/cleaned injectors, checked/adjusted all intake connections and junctions. 
54000 mi A bolt backed out of the tensioner for the accessory drive belt that runs the alternator and power steering. Alerted by belt squeal, I repaired this myself in a Wal-Mart parking lot because the bolt was still present, just loose from the tensioner.
