Common Faults & Reliability

These are the most common documented problems for the Subaru Forester Mk3 (SH), sorted by their typical impact and frequency.

Boxer Diesel Crankshaft Failure

high severity

The EE20 diesel in SH Foresters is notorious for snapped crankshafts or spun main bearings, often turning the car into an uneconomic repair.

Est. repair cost:£3,000–£6,000

Rear Self-Levelling Suspension Failure

medium severity

Factory self-levelling rear dampers lose pressure and leak, leaving the back of the car sagging when unladen and especially when towing or carrying weight.

Est. repair cost:£500–£1,200

Rear Subframe and Mount Corrosion

medium severity

UK road salt can attack the rear subframe, suspension mounts and brake pipe area long before the body panels look especially rusty.

Est. repair cost:£400–£1,500
