The 2010 Lancer is generally a solid commuter car with good bones, but the CVT transmission and certain engine internal failures are the major reliability concerns that can turn expensive quickly.
CVT Transmission Failure (F1C1A CVT)
Common · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Shuddering or jerking during acceleration, especially from a stop, Whining or grinding noises under load, Hesitation when shifting between drive ranges, Check engine light with P0868 (line pressure low) or P0841 codes, Transmission overheating warnings
Fix: CVT fluid and filter service may buy time if caught early (2-3 hours labor), but most need transmission replacement or rebuild. Mitsubishi issued a warranty extension to 10yr/120k on some units. Replacement is 8-12 hours labor.
Estimated cost: $3,500-5,500
Piston Ring Land Failure (2.0L and 2.4L engines)
Occasional · high severity
Typical onset: 90,000-150,000 mi
Symptoms: Excessive oil consumption (1 qt per 500-1000 miles), Blue smoke from exhaust on startup or acceleration, Loss of compression in one or more cylinders, Misfires and rough running, Check engine light with P0301-P0304 misfire codes
Fix: Requires engine rebuild with new pistons and rings, or short block replacement. Root cause is often carbon buildup from lack of direct injection cleaning or aggressive driving on cold engine. Full rebuild is 18-24 hours labor.
Estimated cost: $3,800-6,000
Serpentine Belt Tensioner and Idler Pulley Failure
Common · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Squealing or chirping noise from front of engine, especially on cold starts, Belt wear on one edge or center, Visible wobble in pulley when engine is running, Battery light or overheating if belt snaps
Fix: Replace tensioner assembly and any worn idler pulleys as a set along with new belt. The tensioner spring weakens over time. 1.5-2 hours labor. NHTSA recall 13V-374 covered some units.
Estimated cost: $250-450
Transmission Oil Cooler Line Leaks
Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Red transmission fluid puddles under vehicle, Fluid leaking near radiator area, Low transmission fluid warnings, Transmission slipping or overheating
Fix: The rubber lines and metal fittings crack from heat cycling. Replace both cooler lines and inspect radiator-mounted cooler for cross-contamination. 2-3 hours labor plus fluid refill and flush recommended.
Estimated cost: $400-700
HVAC Blower Motor Failure
Occasional · low severity
Typical onset: 80,000-130,000 mi
Symptoms: Blower only works on high speed setting, No air flow from vents at any setting, Squealing or grinding noise from dashboard, Intermittent blower operation
Fix: Usually the blower motor itself or the resistor module. Motor is behind glove box, 1.5 hours labor. Resistor is 0.8 hours. Test resistor first as it's cheaper. NHTSA recall 17V-355 covered some blower motors.
Estimated cost: $200-450
Front Lower Control Arm Bushings
Common · low severity
Typical onset: 70,000-120,000 mi
Symptoms: Clunking noise over bumps from front end, Steering wander or imprecise handling, Uneven front tire wear (inside edge), Vibration through steering wheel
Fix: Rear bushings in the lower control arms deteriorate and crack. Replace control arms as complete assemblies (bushings alone are not serviceable). 2.5-3 hours labor plus alignment.
Estimated cost: $450-750
Evaporative Emissions System Leaks
Occasional · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Check engine light with P0455 (large EVAP leak) or P0456 (small leak), Fuel smell near fuel tank or engine bay, Difficulty filling fuel tank (pump clicks off early), Hissing sound when opening fuel cap
Fix: Common culprits are cracked purge valve, deteriorated hoses, or faulty fuel tank pressure sensor. Smoke test required to pinpoint. Purge valve is 0.8 hours, sensor is 1.5 hours (requires tank drop).
Estimated cost: $150-600
Owner tips
Change CVT fluid every 30,000 miles with Mitsubishi SP-III or equivalent — this is critical and often neglected
Use top-tier gasoline and add fuel system cleaner every 5,000 miles to prevent carbon buildup on intake valves (non-GDI engines)
Inspect serpentine belt system at every oil change after 50,000 miles — preventive replacement is cheap insurance
Address any oil consumption early — continuing to drive with low oil accelerates piston ring damage
Buy one with documented CVT fluid changes and no history of oil consumption; budget $1,000-1,500 for deferred maintenance on any 100k+ example.

ELECTRICAL SYSTEM · 15V232000
2015-04-20
Mitsubishi Motors North America, Inc. (Mitsubishi) is recalling certain model year 2009-2010 Mitsubishi Lancer vehicles manufactured January 12, 2009, to July 6, 2010, 2009-2010 Outlander vehicles manufactured January 12, 2009, to August 27, 2010, 2010 Lancer Sportback vehicles manufactured June 17, 2009, to June 8, 2010, and 2010 Lancer Evolution vehicles manufactured July 14, 2009, to August 4, 2010. The affected vehicles have an electronic control unit (ECU) that controls the head lights, tail lights, and windshield wipers. Due to a manufacturing error, the voltage inside this ECU may be unstable.
Consequence: Unstable voltage could result in intermittent failure of the vehicle's head lights, tail lights, and windshield wipers. If the headlights and/or windshield wipers fail, the driver could have reduced visibility. If the tail lights fail, the vehicle could be less visible. Either condition increases the risk of a crash.
Remedy: Mitsubishi will notify owners, and dealers will replace the affected ECU, free of charge. The recall began on June 15 ,2015. Owners may contact Mitsubishi customer service at 1-888-648-7820. Mitsubishi's number for this recall is SR-15-002.

(Mitsubishi) is recalling certain model year 2009-2011 Lancer vehicles manufactured March 16, 2009, to March 30, 2011, 2010-2011 Lancer Sportback vehicles manufactured June 17, 2009, to December 1, 2010, 2010-2011 Lancer Evolution vehicles manufactured July 14, 2009, to January 7, 2011, 2009-2011 Outlander vehicles manufactured February 10, 2009, to June 22, 2011, and 2011 Outlander Sport vehicles manufactured August 26, 2010, to November 19, 2010. In the affected vehicles, the blower motor may fail.
Consequence: Failure of the blower motor may reduce the performance of the windshield defroster, diminishing the driver's visibility and increasing the risk of a crash.
Remedy: Mitsubishi will notify owners, and dealers will replace a suspect blower motor, free of charge. The recall began on June 15, 2015. Owners may contact Mitsubishi customer service at 1-888-648-7820. Mitsubishi's number for this recall is SR-15-003.
ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:BELTS AND ASSOCIATED PULLEYS · 14V562000
