2010 MITSUBISHI GALANT

Typical onset: 60,000-120,000 mi

Symptoms: Burning 1+ quart every 500-1,000 miles with no visible external leaks, Blue smoke from exhaust on startup or acceleration, Check engine light for lean codes (P0171/P0174) as oxygen sensors foul, Eventually: rod knock, seized engine if oil level drops unnoticed

Fix: Root cause is defective piston rings allowing oil into combustion chambers. Proper fix requires complete engine teardown, new rings and pistons, honing cylinders—basically a full rebuild. Many owners run it on a quart-per-week regimen until catastrophic failure, then either replace engine or scrap car. Engine rebuild: 18-24 labor hours. Short block swap: 12-16 hours.

Estimated cost: $3,500-6,500

Typical onset: 70,000-130,000 mi

Symptoms: Pink or milky transmission fluid (coolant contamination), Transmission slipping, delayed engagement, or shuddering, Overheating transmission temp gauge if equipped, Coolant level mysteriously dropping, strawberry-milk appearance in overflow

Fix: Internal cooler in radiator corrodes, allowing ATF and coolant to mix—kills the CVT quickly. Requires radiator replacement, complete transmission flush (often too late), and new cooler lines. If contamination has circulated, CVT rebuild or replacement needed. Radiator + lines + flush: 3-4 hours. Add 8-12 hours if transmission damaged.

Estimated cost: $800-1,200 (if caught early); $3,000-5,000 (with CVT replacement)

Typical onset: 80,000-140,000 mi

Symptoms: Clunking when shifting from Park to Drive or Reverse, Excessive engine movement visible when revving in Park, Vibration through shifter and floor at idle, Harsh engagement on acceleration from stop

Fix: Rubber in rear transmission mount deteriorates, allowing powertrain to rock excessively. Common failure point on all Mitsubishis of this era. Replace mount and inspect front engine mounts while you're under there. 1.5-2 hours labor.

Estimated cost: $250-400

Typical onset: 90,000-150,000 mi

Symptoms: Hard starting, especially when hot, Loss of power under acceleration or uphill, Intermittent stalling at idle after driving, Check engine light with fuel trim or fuel pressure codes

Fix: The high-pressure filter inside the fuel tank clogs from debris or degraded tank liner. Mitsubishi calls it 'lifetime,' but it's not. Requires dropping fuel tank to access pump module. Often find rusty tank internals. 2.5-3.5 hours labor, more if tank straps are rusted.

Estimated cost: $400-700

Typical onset: 50,000+ mi

Symptoms: Rattling or ticking noise from engine bay on cold start, Noise disappears or changes pitch as engine warms up, Sound is metallic, distinct from valve tick

Fix: Heat shields on exhaust manifold crack or lose mounting tabs. Technically covered under recall 13V-527 for fire risk, but many dealers won't honor it past 10 years. Can remove shield entirely if not in a fire-prone area, or weld/secure with high-temp wire. 0.5-1 hour labor if removing.

Estimated cost: $80-200 (often free under extended recall coverage)

Typical onset: 80,000-120,000 mi

Symptoms: Check engine light with P0441, P0455, or P0456 (EVAP leak codes), Fuel smell near rear of vehicle when parked, Difficulty fueling—pump clicks off repeatedly

Fix: Purge valve sticks or canister cracks from road debris. Diagnose with smoke test. Purge valve replacement: 0.8 hours. Canister replacement (less common): 1.5 hours. Sometimes just a loose or cracked vapor hose.

Estimated cost: $200-500
