Power steering rack leaks are common on 2005-2014 Subaru Legacy models, often leading to a loss of power steering assist if not addressed.

This is one of several documented Legacy problems we track, and it fits inside the broader Reliability & Common Problems guide. If you're weighing repair against replacement, cross-check the Subaru repair-cost database and any open NHTSA recalls on your VIN before booking a shop.
The power steering rack on these Legacy models often develops leaks from the seals, particularly at the boots where the tie rods attach. This allows power steering fluid to escape, leading to a low fluid level in the reservoir and ultimately a loss of hydraulic pressure for power steering assist. If left uncorrected, the pump may also be damaged due to running dry.
The seals within the power steering rack, particularly the pinion seals and inner tie rod seals, are prone to deterioration and failure over time due to age, heat cycles, and hydraulic pressure.
