Subaru Legacy GT Problems

The mid-sized Subaru Legacy GT was unveiled in 1989. The vehicle was specially designed to offer a Subaru variant to North American car buyers. It was hoped these would compete with the Toyota Camry and Honda Accord in the mid-sized car market. The Legacy is Subaru’s flagship car. High performance variants of the Legacy have been built to compete with the Alfa Romeo 159, Audi A4 and the BMW 3 Series. Another sport-utility variant called the Outback became a runaway success. Below are frequently asked questions on issues regarding Subaru Legacy GT that have been answered by the Experts.

What could cause a Subaru Legacy GT check engine light to come on and temperature gauge to rise after two rough starts and the engine stopped when idling

Check the coolant level once the engine has cooled down letting the radiator pressure release. Low coolant could be a possible cause of engine heating, but there are several others. To be certain about the source of the problem, have a computer scan done on the engine which will generate a failure code.

Why would a 2005 Subaru Legacy GT wagon not start after a battery change, the engine cranks but doesn’t fire?

Since the keys were lost and replaced and all the fuses in the car are good, its possibly a faulty key or an immobilizer issue. Try starting the car with another set of keys. If it starts, replace the faulty key for which the security code will be needed. This is usually embossed on a metal tag with the original keys that came with the car.

After changing the hub on a 2005 Subaru Legacy GT the cruise control light flashes but the check engine light remains off. What could the cause be?

When in cruise control the speed is controlled by feedback from wheel sensors. The cruise module will have its own stored code. Since the problem started after changing the hub,, there is possibly an issue with the air gap. This would be between the bearing and speed sensor, or with the sensor itself. To be certain have the car scanned by a Subaru dealer to check the codes in all modules.

What is the best way to troubleshoot a 2010 Subaru Legacy as the power windows have stopped operating though the fuses are good?

The first step is to inspect the slow blow fuses (SBF). These are 30-40 amp fuses located in the fuse box in the engine compartment. If the fuses and fuse links are good locate the relays and swap them. The problem could lie here.

What could be wrong with a 2005 Subaru Legacy it is leaking engine oil fast without leaving any visible signs and has a continuous knock?

Turbo engines are particularly sensitive to fresh oil and coolant. A continuous knock and no signs of a leak, signifies the engine or the turbo is burning oil fast. This should be evident by smoke from the exhaust while accelerating, a sign of bad turbo seals. This might suggest that the motor will have to be replaced or overhauled, and the turbo inspected.

The Subaru Legacy GT is considered by many to be one of the finest cars produced by the company. One of its USPs is the all-wheel-drive which is a standard feature. Generally if well maintained this is a reliable car. However there are times a user might come across a problem which is best discussed with an Expert on Subaru vehicles.
