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.

Front engine oil leaks can develop from the camshaft seal and the crankshaft front seal. If one or more seals require replacement, it may be wise to consider replacing the timing belt as well. These seals are commonly inspected and replaced as needed as part of a timing belt service.

Subaru issued a recall (WWG-90) because the mass air flow sensor has a manufacturing defect.

The leak may develop from the oil pump seal. Our technicians prefer to use thread locker when replacing the seal to prevent the bolts from becoming loose again.

I had the battery replaced over summer, but it died immediately. It needed an alternator. The alternator failed and I had it replaced again - but it was a warranty repair. Went to a good mechanic for the work.
