2015 Mitsubishi Lancer
Vehicle Specs & Maintenance Data
The 2015 Mitsubishi Lancer maintenance specs on this page cover the key fluids, torque values, and wear items you need for routine service. Use these numbers as a quick reference when performing oil changes, tire rotations, brake jobs, and other scheduled maintenance on your Mitsubishi Lancer.
For oil changes, the 2015 Mitsubishi Lancer takes 0W-20 Full Synthetic motor oil with a capacity of 4.5 quarts. Brake fluid type is DOT 3, the recommended coolant is Dia Queen Super Long Life Coolant (Green), and transmission fluid is Mitsubishi CVTF-J4. Always use the manufacturer-recommended fluids to maintain warranty coverage and engine longevity.
When mounting wheels on the Mitsubishi Lancer, torque the lug nuts to 80 ft-lbs using a calibrated torque wrench. Over- or under-torquing can lead to warped brake rotors or loose wheels. Re-torque after 50 to 100 miles on newly installed wheels.
Owners of the 2015 Mitsubishi Lancer have reported 5 common issues including "CVT Transmission Shudder and Failure", "AC Compressor Failure" and "Front Strut Mount and Bearing Noise". Scroll down to the Diagnostics tab for detailed descriptions, solutions, and estimated repair costs.
Specifications on this page are compiled from multiple publicly available sources including manufacturer documentation, NHTSA data, and automotive databases. Always cross-reference with your owner's manual or official factory documentation before purchasing parts or performing any service.

Common problems reported by 2015 Mitsubishi Lancer owners, with recommended fixes and estimated repair costs.
CVT Transmission Shudder and Failure
The Jatco CVT used in the Lancer develops shuddering during acceleration, hesitation from stops, and eventual failure. The transmission may enter limp mode, display a check engine light, and exhibit whining noises. Failures are common between 60,000 and 100,000 miles, and the CVT is not rebuildable by most shops, requiring complete replacement.
Perform regular CVT fluid changes every 30,000 miles using genuine Mitsubishi CVTF-J4 fluid. If shuddering has developed, a fluid change and TCM reprogram may help temporarily. For severe cases, the CVT assembly must be replaced with a new or remanufactured unit. Check if Mitsubishi's extended CVT warranty applies to your vehicle.
Est. Cost: $300 - $4,500AC Compressor Failure
The AC compressor can fail prematurely, with the clutch bearing being a common failure point. Symptoms include a squealing noise with the AC engaged, intermittent cooling, and eventually no cold air output. The compressor clutch may also slip, producing a burning rubber smell. Some owners report the compressor seizing completely.
Replace the AC compressor, receiver/drier, and expansion valve as a complete system. If the compressor seized, flush the AC lines to remove metallic debris before installing the new compressor. Recharge with the correct amount of R-134a refrigerant and verify system pressures.
Est. Cost: $700 - $1,500Front Strut Mount and Bearing Noise
The front strut mount bearings wear out prematurely, producing a creaking, popping, or groaning noise when turning the steering wheel, especially at low speeds or when parking. The noise is most noticeable in cold weather. Worn strut mounts also affect alignment angles, causing uneven tire wear.
Replace the front strut mounts and bearings. Most technicians recommend replacing the complete strut assembly (strut, mount, and bearing) rather than just the mount, especially if the struts have high mileage. Perform a four-wheel alignment after strut replacement to correct camber and caster angles.
Est. Cost: $300 - $700Rear Drum Brake Self-Adjuster Issues
The rear drum brakes on non-Evolution models can develop self-adjuster issues where the adjuster mechanism seizes or fails to properly adjust the brake shoes. This results in excessive pedal travel, rear brakes that do not engage properly, and a parking brake that does not hold the vehicle. The drums can also become scored from contact with the worn shoes.
Remove the rear drums and inspect the self-adjuster mechanism, brake shoes, and hardware. Clean and lubricate the adjuster mechanism or replace it if seized. Replace the brake shoes and hardware kit. Machine or replace the drums if they are scored. Manually adjust the brake shoes before reinstalling the drums.
Est. Cost: $150 - $400Engine Oil Leak from Valve Cover Gasket
The valve cover gasket on the 2.0L and 2.4L engines can begin to leak oil onto the exhaust manifold, producing a burning oil smell. The gasket hardens and shrinks with age and heat exposure. Oil may drip onto the ground or accumulate around the spark plug wells, potentially causing misfires.
Replace the valve cover gasket and the spark plug tube seals included in the gasket set. Clean the mating surfaces of the valve cover and cylinder head. Apply a small amount of RTV sealant at the cam cap/head junction points per Mitsubishi procedure. Replace spark plugs if they are oil-fouled.
