I have gone through one head gasket on Jan 2003. The head gasket went out in Dec of 2003 and the whole engine had to be replaced. In January of 2004 I had the overhead camgaskets go out on the car as well as the the oxygen sensor. I have had more issues but it would be a small book. Subaru has been relativly unresponsive even after many phone calls and letters to my concerns. Every part was replaced however there seems to be a poroblem with my new engine since there is now an investigation within Subaru. They refuse to pay the dealership for the new engine replacement which raises the question of was this a new engine or what is wrong with the new engine.

Told by dealer that left head gasket is leaking coolant. $1,600 to have head removed, planed and regasketed, and reinstalled. 75,000 highway miles on very well kept vehicle. I did not smell coolant until after a service in mid Aug. 03 during which they flushed my coolant system.
