Common Problems & Known Issues

The 2013 Forester with the 2.5L naturally-aspirated FB25 engine is generally more reliable than older EJ-series Subarus, but it still suffers from oil consumption issues leading to eventual internal engine damage, plus typical Subaru CVT vulnerabilities and a notable Takata airbag recall.

Excessive Oil Consumption / Piston Ring Failure (FB25 Engine)

Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Burns 1+ quart oil every 1,000-1,500 miles without visible leaks, Blue smoke on cold start or acceleration, Check engine light with misfire codes (P0301-P0304) once oil starvation worsens, Knocking or ticking from low oil between changes
Fix: Subaru issued extended warranty coverage through 2016 for some VINs, but most are now out of warranty. Fix requires complete short-block replacement or full engine rebuild with updated pistons and rings. 12-16 labor hours for short-block swap at an indie shop.
Estimated cost: $4,500-7,000

CVT Transmission Cooler Line Failure

Occasional · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Transmission fluid puddle under vehicle (red/pink fluid), Transmission overheating warning light, Harsh shifting or slipping if fluid level drops significantly, Cooler lines corrode at crimped fittings near radiator
Fix: Replace both CVT cooler lines and top off fluid. If trans ran low on fluid before discovery, internal damage may already be done. 2-3 hours labor for just the lines; CVT replacement is 8-10 hours if damaged.
Estimated cost: $400-800 (lines only), $4,000-5,500 (full CVT if damaged)

Takata Airbag Inflator Recall (Passenger Side)

Common · high severity
Symptoms: No symptoms — this is a latent safety defect, Inflator propellant degrades over time in humid climates, Can explode with excessive force, sending metal shrapnel into cabin during deployment
Fix: Free recall repair at any Subaru dealer (NHTSA campaigns). Takes 1-2 hours. Check VIN at NHTSA.gov or Subaru's recall site — many 2013 Foresters still have unrepaired airbags in circulation.
Estimated cost: $0 (recall repair)

Transmission Mounts Collapse

Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Clunk or thud when shifting from Park to Drive or Reverse, Excessive vibration at idle in Drive, Visible sag of transmission when inspecting from below
Fix: Replace rear transmission mount (most common failure point). Sometimes front mount also needed. 1.5-2 hours labor. OEM mounts preferred — aftermarket ones wear faster.
Estimated cost: $250-450

Head Gasket Seepage (Less Common Than Older EJ Engines)

Occasional · medium severity
Typical onset: 100,000-150,000 mi
Symptoms: Small external coolant leak at head-to-block mating surface, White crusty residue on outside of engine block, Slight coolant smell after driving, no overheating yet, Not the catastrophic failure seen in EJ25D engines, but still needs attention
Fix: Replace both head gaskets, resurface heads if warped, new timing components while in there. 10-12 hours labor. Catching it early prevents overheating damage.
Estimated cost: $2,200-3,200

Brake Line Corrosion (Rust Belt / Salt States)

Occasional · high severity
Typical onset: 80,000+ mi
Symptoms: Soft or spongy brake pedal that doesn't improve with bleeding, Visible rust perforation on steel brake lines near rear subframe, Brake fluid leaking along undercarriage, Fails state safety inspection
Fix: Replace affected steel lines — sometimes all four corners if corrosion is widespread. 4-6 hours labor depending on how many lines need replacement. Use coated or stainless lines in salt states.
Estimated cost: $600-1,200
Owner tips
  • Check oil level every 500-1,000 miles religiously — oil consumption can creep up suddenly and starve the engine before the low-oil light comes on.
  • Use Subaru OEM or high-quality 0W-20 synthetic oil; cheap oil accelerates ring coking on the FB25.
  • Service CVT fluid every 30,000-40,000 miles (Subaru says 'lifetime' but that's optimistic for longevity).
  • Verify Takata airbag recall completion before purchase — it's a legit safety hazard and free to fix.
  • Undercoat or fluid-film the undercarriage annually if you're in a salt state to slow brake line corrosion.
Decent used buy if oil consumption has been monitored and the Takata recall is done, but budget for a possible short-block around 100k miles — many FB25 engines don't make it to 150k without a rebuild.
