Known Problems

The Check Engine Light may illuminate because of a failed knock sensor. Although the sensor often tests okay, it can fail intermittently, while the vehicle is being driven.

The front oxygen (air fuel ratio) sensor element may develop a crack, causing the Check Engine Light to illuminate. Subaru has recalled certain models to replace sensors that may fail. The Subaru service program number is WXW-80, this is not a government mandated recall.

 

There have been reports of "clutch chatter," particularly when driving the vehicle from a cold start. If the issue was reported by the owner while the vehicle was still under warranty, the dealer may replace the clutch with improved parts.

A noise in the clutch called "clutch chatter" is common if the car is driven without allowing it to warm up.

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.

Sometimes the Check Engine Light illuminates because the computer detects misfires. Subaru released an improved spark plug wire set to solve the problem. The ignition coil should also be inspected for carbon tracks or short circuits between the contacts

Rear engine oil leaks may occur because Subaru used a plastic oil baffle plate that failed. This issue is often misdiagnosed as a crankshaft rear oil seal leak or an oil pan gasket leak. Subaru released an updated design of the baffle plate made from aluminum that stops the oil leak.

A failure in the anti-lock brake system (ABS) causes the ABS pump to continuously run, which will eventually wear down the battery. An improved ABS relay is available to solve the problem.

Premature timing belt failure is not uncommon. The recommended service interval is 60K, but belt failures before that mileage have been noted. This 1.8L engine is considered "free-wheeling", therefore the chances of valve damage if the timing belt fails is minimal.

Electrical issues are not uncommon, often they can be traced to corrosion inside electrical connectors exposed to the elements. Any corrosion found should be completely cleaned and the affected connector packed with dielectric silicone grease.

A rattle type noise may be noted from the tailgate area. This can commonly be repaired by modifying or changing the tailgate weather seal.
