2003 Subaru Legacy Problems

Engine -- Verified

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.

Engine -- Verified

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.

Engine -- Verified

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.

Brakes -- Verified

There is a technical service bulletin on the ABS control module. It is replaceable without having to replace the entire anti-lock brake hydraulic unit. Previously, the ABS control module was only available as a complete assembly that included the hydraulic unit.

2003 Subaru Legacy Reviews

I am the original owner of an 03 Legacy SE wagon that currently has 131,000 miles. The car has been reliable, but has cost a small fortune in repairs. Head gaskets, rear wheel bearing, 2 exhaust systems, the rear light cluster leaked and needed replacement, rear stabilizer bar broke, front control arm replaced, and today, one of the glass sunroofs shattered. Tires last around 30,000, and must be replaced in sets of 4, fuel economy is around 25mpg in suburban driving. Engine is noisy with a bad case of piston slap (normal according to Subaru), and it leaks oil. The head gaskets are leaking again, but using Subaru cooling syatem conditioner has slowed the leak to where I add coolant about once every two months.
