2005 Subaru Legacy 4dr Wagon

turbocharged 250hp 2.5L H4 5-speed manual AWD

72000 mi US $40 Coolant overflow/failed rad cap problem fixed per TSB 09-52-08 
75000   Oil consumption >1L per 1000mi. Leakdown and compression test. 60% loss -- 105 psi (normal 175-145psi). Suspect piston ring failure. Note: passed later test, now suspect turbo. 
84000   Radiator had a blockage. Rodded out radiator and replaced coolant. Shop also found intercooler leaking ($800 of repair in parts, replaced with aftermarket part). This was likely caused by aftermarket parts. 
95000   Two blown up piston rings 
98000   Fluid filled mount was leaking. Replaced. Dealer had never seen anything like it. (Tracked car) 
108500   Replaced squealing AC tensioner. 
116000   Found oil leak in a hose. Put over to order parts. Possible warranty item from engine replacement. 
117000   Leak in hose repaired. Had to replace intake hose as well as it was looking rough. 
135000   During clutch job, dealer noticed a rear seal leak. 
135000   Leaky valve covers (both sides) 
44000   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   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 US $176 OBD reported "system too lean", inspected/cleaned injectors, checked/adjusted all intake connections and junctions. 
54000   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.

2005 Subaru Legacy 4dr Sedan

turbocharged 250hp 2.5L H4 5-speed manual AWD

42000 mi US $50 Faulty fuel injector, causing misfire in cylinder 3. 
29000   Originally brought car in for check engine light and the Turbo Fan Relay recall. The car ran rough at idle and studdered at 2800rpm. Dealer replaced the ECM(computer). 
34000   Rough idle again and poor performance. Dealer replace #2 injector, but did not solve the problem. Possibly another injector is defective along with a needed ECM reflash dealer didn't have time to complete last visit. Bringing back to dealer to fix again. 
37000 US $542 Rough idle and poor performance still exist, dealers dianostic computer was down and could not determine which injector was bad. Must go back to dealer, AGAIN! Rough idle and poor performance problem still. Different dealer(out of town) did not find anything wrong with the injectors but had fouled up plugs. Preformed 30,000 service which included new plugs, carbon cleaning, etc. Ran great for about 100 miles the 
41000   Replaced the number 4 injector and the car has been running great. 
51000   I had the turbo banjo bolt removed after reading a TSB that the banjo filter could become clogged and starve the turbo of oil causing it to seize. Dealer recommended removal of filter rather than cleaning every 3000 miles at a cost of $90 in labor. 
92000   Valve cover gasket leak. Typical expensive repair on all subaru's around 100k. Had them replaced along with I minor oil leak from the oil filter attachment.
