2015 Subaru Legacy

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.

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.

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.

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.

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.

Subaru of America, Inc. (Subaru) is recalling certain model year 2015 Legacy and Outback vehicles manufactured on July 20, 2015. The brake fluid used in these vehicles may contain excess moisture which may adversely affect the performance of the electronic stability control system. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 126, "Electronic Stability Control Systems."

Poor performance of the electronic stability control system when it is activated may result in a loss of vehicle control, increasing the risk of a crash.

Subaru will notify owners, and dealers will perform an ABS activation, then flush and replace the brake fluid, free of charge. The recall began on May 20, 2016. Owners may contact Subaru customer service at 1-800-782-2783. Subaru's number for this recall is WTC-64.

Subaru of America, Inc. (Subaru) is recalling certain 2015 and 2016 model year Subaru Legacy 4-Door and Outback vehicles manufactured July 3, 2015, to July 27, 2015. Transmission oil may leak from a deformed seal cap on the propeller shaft yoke.

If the transmission oil leaks onto the exhaust pipe, there is a possible risk of fire.

Subaru will notify owners, and dealers will replace the propeller shaft, free of charge. The recall began on August 28, 2015. Owners may contact 1-800-782-2783. Subaru's number for this recall is WQU-56.

Subaru of America, Inc. (Subaru) is recalling certain model year 2015 Legacy vehicles manufactured March 10, 2014, to April 16, 2015, Outback vehicles manufactured February 24, 2014, to April 16, 2015, Impreza vehicles manufactured September 9, 2014, to April 14, 2015, XV Crosstrek vehicles manufactured October 16, 2014, to April 15, 2015, and 2016 WRX vehicles manufactured March 23, 2015, and equipped with the Eyesight Driver Assist System. If the switch that activates the brake lights fails, the automatic pre-collision braking component of the driver assist system will not function.

If the automatic pre-collision braking system does not function as intended, the vehicle will not react to an obstacle in its path, increasing the risk of a crash.

Subaru will notify owners, and dealers will reprogram the driver assist system, free of charge. The recall began on July 20, 2015. Owners may contact Subaru customer service at 1-800-782-2783. Subaru's number for this recall is WQS-54.
