2006 Subaru Forester 4dr SUV

173-horsepower 2.5L H4 4-speed automatic AWD

61000 mi Not exactly a repair, more like a diagnosis + wait and see. Slight leakage of oil AND coolant from one cylinder head. Engine has leaked coolant from new. Amount varies with season. Subaru dealer(s) always denied any problem. My independent guy says it's quite common with (older?) Subarus. Keep an eye on it! 
157000 mi

US $1000
Check engine light with Cylinder 4misfire. Could be rings or head gasket (again). Mechanic suggested new engine or sell it. I have already put 2 head gaskets in it. Decided to sell it currently shopping for a new vehicle.

Faulty Catalytic sensor fixed by spacing outside exhaust stream. 
154000 mi Diagnosed oil leak from engine to be leaking oil drain plug. Replaced with Fumoto F-105N Engine Oil Drain Valve which has resolved that leak. Additional oil leak from the valve covers not resolved due to amount of work needed to repair that on this type of engine.

117800 mi OIL LEAK! This car has used inordinate amounts of oil from the beginning of my ownership. I have spent many hundreds of dollars having it checked and tuned up, at two different dealers (Napleton in Rockford IL and Dahl's in La Crosse WI). 
139300 mi

Smelled burning oil, turned out the gasket was leaking. The dealer replaced the timing belt, too, as it was getting worn and it has to be removed for the gasket job anyhow.

US $2000
Not sure what the exact problem was but check engine light was flashing. 
68200 mi

US $500
Replaced oxygen sensor 
101000 mi

US $40
A weld on the exhaust system had separated. Car was loud. A new weld was made and car sounds normal again. No functional issues with the repair. I also don't believe it was damage from driving, just from rust. 
93400 mi

US $100
Minor vapor leak. Re-set fault. Happened again. New has cap installed in January. Still problematic. 
104200 mi

US $1477
105 month timing belt change and small oil leak from head gasket repaired. Price is misleading as it is a 10 hr job for the oil leak and timing belt change was preventative/scheduled maintenance and comes off for the repair anyway. 
122000 mi

US $975
The car has had a minor vapor leak for some time and finally got it diagnosed and repaired - required dropping the fuel tank to access the part that was bad (I don't recall what it was). Radiator replaced because of crack found during pressure check after replacing part for vapor leak. 
10000 mi Faulty fuel pump replaced under warranty. The pump was making excessive whine. Dealer determined pump should be replaced. I still think the new pump is a little noisy.
