170-horsepower 2.5L H4 4-speed shiftable automatic AWD

45500 mi   Check engine light, ABS light, Traction control light all illuminated. 
59000   Timing chain tensioner was leaking down overnight. 
28500   cam engine seals leaking resulting in oil leak and low oil levels 
32700   car is still leaking oil, has to go back to shop 
35000   Car leaks oil. Dealer repeated major repair of cam gasket seals. Hopefully this fixes the problem once and for all 
45000   Oil level read below minimum level, suspecting oil is burning off. Dealer has started an oil consumption test. Vehicle seems to burn off all oil in between oil changes. 
12700   oil leaking from valve cover gasket. 
13000   valve cover gasket replaced (warranty) 
14000   4th Trip to Dealer for the same oil leak. Dealer unable to correct problem. After last trip to Dealer on 12/07 I found RTV sealant glopped over valve cover gasket to attemopt sealing the leak. Improper repair, returned to Dealer for repair 
22000   Started oil consumption test with dealer. Oil consumption is higher than expected, using approx. 1 qt. for every 3000 miles. 
68700   Start test to determine how much oil is leaking at valve covers. Oil is dripping on exhaust, burning and creating smoke. When car is stopped it enters the cab through a/c. Have to keep a/c on recirc. 
19000 US $80 Going thru a 1/2 to 3/4 of oil every 1000 miles.... 
30000   oil consumption test. Dealing w /subaru of america directly on resolution of problem. 
13000   Left side timing chain tensioner replaced with revised part per TSB. Caused a loud knocking sound on cold start up since new. Issue resolved. 
16000   Previous replacement of timing chain tensioner. Dealer did not seal timing cover properly so it was leaking oil on to the exhaust. Brought back to dealer and they removed and resealed the timing cover. Seems to be fixed for now.  
32000   Engine and/or transmission hesitation when turning corners and accelerating. Doesn't respond for a couple seconds, then usually... 
45000   Oil leak on driver side cylinder head area. Dealer found leaking valve cover gasket. Replaced gasket. They found there was still an oil leak. Found cam "cap" was was cracked. Replaced cam cap. Brought car home and found it still leaking. Returned car to dealer due to continuing oil leak. Dealer took apart valve cover and cam cap and resealed everything. Seems to be fixed now. 
56700   Oil leak from timing cover. Removed timing cover and installed a new one. Car still leaking oil from left cylinder head area. Also repaired previously. Has been to the dealer for both leaks multiple times. 
4000   Engine was making noise like a sewing machine. The vehicle was admitted for TSB 02-117-11 Left side cylinder head, intake camshaft, intake valves and rocker arm pivots needed to be replaced. Vehicle replaced, due to manufacture defect. 
1860   CEL on, same as last visit. Dealer discovered condensate in the fuel vapour recovery line from the gas tank - dealer thinks either faulty installation or bad design as there is a low spot in line before the drain. Dried out, CEL off now. 
19840   Engine sometimes made noise on cold-starts; determined was covered by TSB for timing chain tensioner. Replaced tensioner, does not make noise anymore. 
1800   ECM reflashed. Oil consumption test started as no sign of oil leaking/burning could be detected. 
2300   Rattle from the spare tire area of the vehicle. Oil consumption check. Developed engine knocking. It was explained to me that the knocking is typical of the boxer engine; some louder than others. 
3700 US $40 Oil consumption check plus oil change. Dealer says the fresh oil change should resolve the oil consumption now that the engine has been broken in. No start. Towed to dealer. Very rough idling at start up after the no-start repair. Smell of raw fuel. Occasional stall. Oil consumption issue not resolved. Dealership says contact Subaru of America as they cannot fix the issue. 
5000   Very rough idle; vehicle would not stay running. Smell of raw fuel, enough to cause eyes to burn.
