2010 SUBARU EXIGA

Typical onset: 80,000-130,000 mi

Symptoms: white smoke from exhaust on cold start, coolant loss with no visible leak, milky oil on dipstick, overheating under load, bubbles in coolant overflow tank

Fix: Both heads typically need removal, deck surfacing, new gaskets, timing components while apart. Genuine Subaru multi-layer steel gaskets are mandatory. Budget 18-24 labor hours for a thorough job including cooling system flush and new thermostat.

Estimated cost: $2,800-4,200

Typical onset: 90,000-110,000 mi

Symptoms: sudden no-start with bent valves if belt snaps, squealing from belt area, visible cracking on belt if inspected

Fix: Interference engine—belt failure destroys valves. Replace every 105k mi or 10 years, whichever comes first. Full kit includes belt, tensioners, idlers, water pump, seals. If belt snaps, add valve job or head work. Prevention is 8-10 hours; post-snap repair adds 12-18 hours for head work.

Estimated cost: $900-1,400 preventive, $3,500-5,500 if valves bent

Typical onset: 100,000-150,000 mi

Symptoms: metallic ticking from valve covers at idle, worse when cold, ticking that persists after warmup, rougher idle quality

Fix: EJ engines use hydraulic lash adjusters that wear or clog with sludge. Full lifter replacement requires heads off or at minimum cam removal. If caught early, fresh oil and Subaru cleaner additive sometimes helps. Full replacement is 12-16 hours labor since it overlaps with timing belt/head work.

Estimated cost: $1,800-3,200 if heads come off, $600-900 for oil flush attempt

Typical onset: 70,000-120,000 mi

Symptoms: shuddering or lurching during acceleration from stop, whining noise under load, burning smell from transmission, limp mode or gear ratio fault codes

Fix: Early Lineartronic CVTs, especially behind turbo engines, suffer from overheating and valve body wear. Fluid changes every 30k mi help but don't prevent all failures. Replacement CVT is a used/reman unit; Subaru doesn't sell internals separately. 10-14 hours labor, plus transmission costs vary wildly on JDM availability.

Estimated cost: $3,500-6,500 with used unit, $5,500-8,000 reman

Typical onset: 60,000-100,000 mi

Symptoms: clunking when shifting into drive or reverse, excessive vibration at idle in gear, visible sagging or cracking of rubber mount

Fix: Rear transmission mount (pitch stopper) wears from engine torque. Aftermarket versions available but OEM lasts longer. 1.5-2.5 hours labor depending on access; turbo models with pitch mount require more disassembly.

Estimated cost: $250-450

Symptoms: transmission fluid leak at cooler lines near radiator, pink fluid dripping under front of vehicle, low transmission fluid warning or slipping

Fix: Steel lines rust through where they route under engine, especially in salt states. Lines are dealer-only parts on Exiga; some shops fabricate custom lines. 2-4 hours labor depending on corrosion severity and if subframe needs dropping.

Estimated cost: $400-850
