2013 MITSUBISHI LANCER EVOLUTION

Typical onset: 60,000-90,000 mi

Symptoms: Harsh or delayed shifts, especially when hot, Transmission entering limp mode after spirited driving, Whining noise from transmission area, Burnt transmission fluid smell

Fix: The SST twin-clutch uses a high-pressure hydraulic pump that wears out, and the factory transmission oil cooler is undersized. Pump replacement requires transmission removal (8-10 hours labor). Upgraded external cooler is mandatory to prevent repeat failure. Many shops replace clutch packs simultaneously since trans is already out.

Estimated cost: $3,500-6,000

Typical onset: 80,000-120,000 mi

Symptoms: Loud metallic ticking at idle that worsens when cold, Check engine light with cam/crank correlation codes (P0016, P0017), Rough idle or hesitation on cold starts, Rattling noise on startup that fades after a few seconds

Fix: The 4B11T uses a timing chain that stretches over time, particularly if oil changes were extended or low-quality oil used. Lifters can also collapse. Full timing chain kit, guides, tensioner, and lifter replacement requires 12-16 hours labor with head removal to access lifters. Must inspect cam phasers and oil control valves simultaneously.

Estimated cost: $2,800-4,500

Typical onset: 50,000-80,000 mi

Symptoms: Excessive driveline clunk during acceleration or deceleration, Vibration felt through shifter or steering wheel, Engine visibly rocking side-to-side under throttle, Difficulty engaging gears smoothly

Fix: The aggressive engine torque destroys OEM rubber mounts quickly, especially the passenger-side transmission mount. Most owners upgrade to polyurethane or solid mounts (expect more NVH). Transmission mount replacement is 2-3 hours, full set of four mounts is 4-6 hours. Alignment check recommended after.

Estimated cost: $600-1,200

Typical onset: 70,000-110,000 mi

Symptoms: Metallic rattling from engine bay at idle or light throttle, Overboost codes or limp mode under hard acceleration, Boost gauge showing higher-than-stock pressures, Hissing or fluttering noises during spool-up

Fix: The factory IHI turbo's internal wastegate actuator rod wears and rattles, or the wastegate flapper doesn't seal properly causing uncontrolled boost. Turbo replacement or rebuild required (6-8 hours labor). Many owners upgrade to aftermarket turbos at this point. Must inspect all boost hoses and diverter valve simultaneously.

Estimated cost: $1,800-3,500

Typical onset: null

Symptoms: Rough running or misfires under boost, Fuel trims showing overly rich or lean conditions, Loss of power at high RPM, Check engine light with fuel pressure or injector codes

Fix: The in-tank strainer/filter can collapse or become clogged, starving the high-pressure fuel pump and injectors. Requires fuel tank drop (3-4 hours labor) to replace filter and inspect pump. Often find rust or debris in tank from old fuel or poor storage. Clean injectors and replace main fuel filter while you're in there.

Estimated cost: $800-1,400

Typical onset: 80,000-130,000 mi

Symptoms: AYC warning light on dash, Whining or grinding noise from rear differential, Pulling to one side under acceleration, Rear diff fluid contaminated with metal shavings

Fix: The electronically-controlled rear diff uses a hydraulic pump to vary side-to-side torque split. Pump seals fail, contaminating fluid and eventually grenading the diff internals. Requires complete rear diff replacement (6-8 hours labor). Mitsubishi discontinued the AYC unit; used or aftermarket only. Some owners convert to standard mechanical diff.

Estimated cost: $3,000-5,500
