Common Faults & Reliability
These are the most common documented problems for the Subaru Outback Mk2 (BH), sorted by their typical impact and frequency.
Head Gasket Failure (EJ25 Engine)
high severityThe 2.5L EJ25 engine often develops external oil and coolant leaks from the head gaskets, or internal leaks leading to overheating. Fault reports and UK MOT data both record engine oil/coolant leaks and exhaust leaks as recurring issues on this generation.
Rear Wheel Bearing Wear
medium severityA common failure on this generation, often starting as a faint drone that many owners ignore until it becomes a roar. Suspension and wheel-bearing faults are a regularly recorded MOT area on the BH Outback.
Front Suspension Knocking (Strut Mounts, Bushes)
medium severityKnocks and clunks from the front end over bumps and on full-lock turns are commonly traced to worn strut top mounts or suspension bushes. Suspension is the second most common MOT failure area on the Outback, so front-end knocks should be taken seriously on a viewing.
