2022 Subaru Legacy
Vehicle Specs & Maintenance Data
The 2022 Subaru Legacy 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 Subaru Legacy.
For oil changes, the 2022 Subaru Legacy takes 0W-20 Full Synthetic motor oil with a capacity of 5 quarts. Brake fluid type is DOT 3, the recommended coolant is Super Long Life Coolant (Blue), and transmission fluid is Subaru ATF. Always use the manufacturer-recommended fluids to maintain warranty coverage and engine longevity.
When mounting wheels on the Subaru Legacy, torque the lug nuts to 89 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 2022 Subaru Legacy have reported 5 common issues including "Excessive Oil Consumption (FB25 Engine)", "CVT (Lineartronic) Shudder and Hesitation" and "Windshield Cracking Without Impact".

Excessive Oil Consumption (FB25 Engine)
The 2.5L FB25 engine is prone to excessive oil consumption, with some owners using a quart or more every 1,000-2,000 miles. Subaru faced a class-action lawsuit over this issue. The root cause is piston ring design that allows oil to pass into the combustion chamber, and the issue tends to worsen with mileage.
Subaru extended the powertrain warranty to 8 years/100,000 miles for oil consumption issues on certain FB-series engines. The dealer will perform an oil consumption test, and if the vehicle consumes more than one quart per 1,200 miles, Subaru will authorize piston ring replacement or short block replacement at no cost under the warranty extension.
Est. Cost: $0 (warranty extension) / $3,000 - $5,000 if not coveredCVT (Lineartronic) Shudder and Hesitation
The Lineartronic CVT can develop a shuddering sensation during light acceleration, delayed response from a stop, and a general lack of refinement. The transmission may exhibit a hunting behavior where the engine RPM rises and falls as the CVT searches for the correct ratio. Fluid degradation contributes to the issue over time.
Perform a CVT fluid replacement using genuine Subaru CVT fluid at 60,000-mile intervals. A valve body replacement or TCM software update may address shuddering issues. Subaru extended the CVT warranty to 10 years/100,000 miles on certain model years. If complete failure occurs, a new or remanufactured CVT is required.
Est. Cost: $300 - $5,000Windshield Cracking Without Impact
Subaru Legacy and Outback windshields are prone to spontaneous cracking without any visible impact point. Cracks often originate from the edge of the windshield near the base or A-pillar area and spread rapidly. Owners suspect that the windshield mounting or body flex contributes to stress cracking. EyeSight-equipped vehicles require a Subaru dealer to recalibrate the cameras after replacement.
Replace the windshield and have EyeSight cameras recalibrated at a Subaru dealer. Use an OEM or equivalent windshield to ensure proper EyeSight function. Some owners have had success getting Subaru corporate to cover replacement through goodwill claims. Glass insurance coverage that includes calibration costs is recommended.
Est. Cost: $500 - $1,200 (including EyeSight recalibration)Battery Drain and Electrical Issues
The Legacy can experience parasitic battery drain, causing a dead battery after sitting for several days. The issue is often attributed to the infotainment system not fully shutting down, the trunk latch actuator remaining powered, or the security system. Bluetooth and Starlink connected services may also prevent proper sleep mode.
Have the dealer check for applicable software updates for the infotainment system and BCM. Perform a parasitic draw test to identify the offending circuit. TSB 11-192-17R addresses certain battery drain issues with an updated head unit software. A trickle charger or battery maintainer is recommended if the vehicle sits for extended periods.
Est. Cost: $0 - $300Rear Suspension Clunk Over Bumps
A clunking or knocking noise from the rear suspension over bumps and uneven road surfaces is commonly reported. The noise is typically caused by worn rear stabilizer bar end links or rear lateral link bushings. The symmetrical AWD system's rear differential mount can also contribute to rear-end noise.
Inspect and replace worn rear stabilizer bar end links, which are the most common source of rear clunking. Check the rear lateral link bushings and trailing arm bushings for cracking or play. Inspect the rear subframe mounting bushings and differential mount. Replace worn components and torque all fasteners to specification.
Est. Cost: $200 - $600
