Blown Head Gaskets; once at 102,000 kilometers and both leaking now at 268,000 kilometers. First repair was warranty, still discussing with my dealer (and Subaru Canada) this time.
Faulty Knock sensor (check engine light) gone twice. First time about 3 years ago, now again in December, 2006.
Exhaust heat shields rattling when accelerating. Continually having them fixed by dealer at least a few times a year.
Strong smell of raw gasoline in winter time when car first starts up. Under some extreme conditions, smell will last for days. Dealer has identified the problem as leaking fuel lines that they re-tighten periodically.
Heated smell in car (like coolant or burning rubber) in hot summer months. Cause has never been pinpointed.
Oil sensor switch leaking now and just replaced at 268,000 kilometers.
In spite of the mechanical issues I had (and continue to have), this car offers a nice quiet and solid ride.
Well appointed options and interior have made long road trips very comfortable. No interior rattles, etc.
Even though it only is powered by a 2.5-liter engine, it still offers decent off the line acceleration and highway passing power.
Was broad-sided by a guy running a red light at 65 KPH (roughly 40 mph) and walked away without a scratch. Very safe car to drive.
