what it costs, and how to spot it on a test drive. Free, from Milo's research on this model.
6known failure points
613NHTSA owner complaints
3safety recalls
$5,500worst-case single repair
The 2.5i is one of the safest used-crossover bets on the road; the 2.0XT turbo is a CVT time bomb wearing a Forester badge
Every documented failure, earliest first
Ordered by the mileage the problem typically appears. VERY HIGH
confidence means it's tied to a documented NHTSA recall, and 1 of these are rated Critical.
0k–12k mi● Watch$0–$400VERY HIGH
Passenger airbag occupant classification sensor fault (SRS light, B1760/B1650 codes)
How to catch it: If the SRS light flickers, get the seat wiring harness inspected early — it's a known intermittent connector issue, not a wholesale airbag failure.
Source: documented (NHTSA recall)
40k–80k mi● Plan$1,500–$2,200MODERATE
Head gasket seepage on the FB25 2.5L (external coolant weep, less catastrophic than legacy EJ25 issues but still occurs)
How to catch it: Watch coolant level monthly and get any sweet smell or slow coolant loss checked immediately — catching it early avoids overheating damage.

50k–70k mi● Plan$250–$500MODERATE
Rear wheel bearing / hub stud corrosion and seizure, especially in rust-belt/salt states
How to catch it: Have a shop apply anti-seize to hub studs at every tire rotation — this single step prevents the classic snapped-stud nightmare.

60k–100k mi● Critical$3,500–$5,500MODERATE
CVT (TR580/TR690) shudder or failure, far more common on the turbocharged 2.0XT than the NA 2.5i
How to catch it: Do a proactive CVT fluid change every 30k miles with genuine Subaru High Torque CVTF — skipping this is the #1 cause of premature failure.

70k–110k mi● Plan$600–$1,800VERY HIGH
XT turbo (FA20DIT) high-pressure fuel pump and carbon buildup on direct-injected intake valves causing rough idle/misfire
How to catch it: Run top-tier fuel and consider a catch can early to slow carbon buildup on the direct-injection valves.
Source: documented (NHTSA recall)
90k–130k mi● Watch$60–$150MODERATE
Rear hatch lift support struts weakening/snapping their mounting pins
How to catch it: Replace both struts as a pair proactively once one feels weak — cheap insurance against a tailgate crashing down on you.
