2004 Subaru Baja Q&A
2004 Subaru Baja Question: Engine Cooling/Head Gasket Problem
Comments show that this head gasket problem is a known and recognized problem on 2004 Bajas. As such, system indicates warranty extension on "some models" with fewer than 100,000 miles and under 8 years old. How do I find out if my vehicle is covered and if the extended warranty is offered to owners other than original owners? - Barney2009
call your local dealer and have them run your vin number to determine if there is any extended warranty. Roy - mastertech6371
The head gasket has a high failure rate due to cooling system problems. Subaru is aware of the problem and has extended the warranty to 8 years/100k miles on many vehicles.
