Imprezas are highly susceptible to premature wheel bearing failure, often at 40,000-80,000 miles. The full-time AWD system adds constant load to all four wheel bearings. Rear bearings fail more frequently than fronts. Road salt, water, and debris accelerate bearing wear. Symptoms… Repairs typically run $250-$700. Severity: medium.
The rear trailing arm bushings on Imprezas corrode and fail, particularly in salt-belt states. The steel sleeve inside the rubber bushing rusts and expands, tearing the rubber apart. This causes clunking noises, vague rear-end handling, and uneven rear tire wear. In severe cases,… Repairs typically run $250-$700. Severity: medium.
