The EJ25 2.5L horizontally-opposed engine in 1998-2010 Foresters is notorious for external head gasket failure. Unlike typical blown head gaskets that cause overheating, the Subaru EJ25 gaskets fail externally, leaking coolant and oil down the sides of the engine. The failure is… Repairs typically run $1,800-$3,500. Severity: high.
The turbocharged EJ255 has thin, cast-piston ringlands that crack under detonation. The large bore, high cylinder temperatures and a flat oil pan that lets oil slosh away from the pickup under cornering make the engine vulnerable: a single knock event (low-octane fuel, poor tune,… Repairs typically run $4,000-$8,000. Severity: high.

The EJ-series front-mounted oil pump has a rotor cover (backing plate) held on by five small screws installed without thread locker at the factory. On high-mileage engines these screws routinely work loose. Pressurized oil then escapes past the rotor cover into the pump body behi… Repairs typically run $150-$900. Severity: medium.
On automatic-transmission Foresters with the 4EAT gearbox, all-wheel drive is managed by an electronically controlled multi-plate transfer (MPT) clutch on the tail of the transmission, modulated by the 'Duty C' solenoid. When the solenoid sticks or the clutch pack glazes, the clu… Repairs typically run $250-$1,800. Severity: medium.
The single knock sensor bolted to the top of the EJ block on SF- and early SG-generation Foresters has a brittle plastic/resin housing that cracks after years of heat cycling directly on the block. Once cracked, the piezo element's circuit reads out of range and the ECU sets P032… Repairs typically run $80-$250. Severity: low.
The wiring that feeds the tailgate runs through a flexible rubber boot between the body and the gate on the passenger side. Every open and close flexes those conductors, and over years the copper work-hardens and fractures inside the insulation, so the wire looks intact from outs… Repairs typically run $50-$450. Severity: low.
The rear differential on SF and SG Foresters hangs on rubber bushings — a large front mount bushing plus rear outrigger bushings tying the diff nose and carrier to the body. The rubber dry-rots and cracks with age, letting the differential rotate and move vertically before it tra… Repairs typically run $150-$700. Severity: low.
