2015 Subaru Legacy Recalls, Issues & Maintenance

The 2015 Subaru Legacy carries 3 open NHTSA recalls — most recently covering electronic stability control (esc) and driveshaft. Owners report 6 recurring issue clusters, led by “Windshield spontaneous cracking without impact.” Subaru's symmetrical AWD system places unusually high demands on differential fluid and transfer case service — skipping these is the most common cause of premature drivetrain wear. Older Subarus with the EJ25 engine (pre-2011) require timing belt replacement; FB and FA engines (2011+) use a maintenance-free chain. Subaru's published intervals below align with the owner's manual Schedule II (severe) which most US drivers qualify for.

ELECTRONIC STABILITY CONTROL (ESC)

Campaign #16V251000 · Apr 27, 2016

Issue: 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."

Risk: 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.

Fix: 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.

POWER TRAIN:DRIVELINE:DRIVESHAFT

Campaign #15V502000 · Oct 8, 2015

Issue: 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.

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

Fix: 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.

FORWARD COLLISION AVOIDANCE: CRASH IMMINENT BRAKING

Campaign #15V366000 · Dec 6, 2015

Issue: 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.

Risk: 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.

Fix: 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.

Essential maintenance

Critical for safety and preventing major damage

Engine Oil & Filter

Every 6,000 mi

Replace 0W-20 full-synthetic oil and filter every 6,000 miles. WRX/STI 2.0L/2.5L turbo: 3,750 miles. Non-turbo FB engines: 6,000 miles severe / 10,000 normal.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

Shop

~$85–$115

DIY

~$25–$55

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.

Tire Rotation

Every 7,500 mi

Rotate tires every 7,500 miles. Critical on Subaru AWD — uneven tread depth across all 4 tires (>2/32") forces the center differential to bind, damaging the AWD coupling.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Often free at the shop where you bought the tires — worth asking before paying.

Brake Inspection

Every 7,500 mi

Inspect brake pads, rotors, calipers, and parking brake every 7,500 miles. Outback and Forester pads commonly last 35,000-50,000 miles depending on terrain.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.

Front Differential / Manual Transmission Fluid

Every 30,000 mi

Replace front differential and manual transmission fluid every 30,000 miles. CVT models use proprietary Subaru CVT fluid — a separate item.

Estimated cost — typical U.S. ranges

Dealer

~$150–$195

Shop

~$105–$135

DIY

~$20–$50

Rear Differential Fluid

Every 30,000 mi

Replace rear differential fluid every 30,000 miles. Use Subaru 75W-90 GL-5 — substitutes can cause whining noises within months.

Estimated cost — typical U.S. ranges

Dealer

~$150–$195

Shop

~$105–$135

DIY

~$20–$50

CVT Fluid (Lineartronic)

Every 30,000 mi

Subaru CVT models (Outback, Legacy, Forester, Crosstrek, Impreza, Ascent): replace Lineartronic CVT fluid every 30,000 miles severe / 60,000 normal. Subaru High-Torque CVT-II fluid only — incorrect fluid destroys the chain-and-pulley system.

Estimated cost — typical U.S. ranges

Dealer

~$360–$500

Shop

~$255–$355

DIY

~$80–$180

CVT fluid is manufacturer-specific and pricey — do NOT substitute conventional ATF.

Timing Belt (EJ25 engines, pre-2011)

Every 105,000 mi

Older Subarus with the EJ25 boxer engine (Forester, Outback, Legacy 1996-2010): replace timing belt every 105,000 miles. FB and FA boxer engines (2011+) use a chain — no scheduled replacement.

Estimated cost — typical U.S. ranges

Dealer

~$935–$1175

Shop

~$655–$825

DIY

Pro only

On interference engines, a snapped belt destroys valves. Worth doing on schedule. Bundle water pump + tensioner — labor is already there.

Brake Fluid

Every 30,000 mi

Replace DOT 3 brake fluid every 30,000 miles or 30 months. Subaru's brake hold and EyeSight automatic emergency braking depend on uncontaminated fluid.

Estimated cost — typical U.S. ranges

Dealer

~$180–$200

Shop

~$125–$140

DIY

~$10–$25

DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.

Important maintenance

Keeps your vehicle running smoothly and efficiently

Engine Air Filter

Every 30,000 mi

Replace engine air filter every 30,000 miles. WRX/STI: inspect every oil change due to the higher airflow demand of the turbo intake.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

5-minute job on most cars; the airbox lid usually has clips, no tools needed.

Spark Plugs

Every 60,000 mi

Iridium plugs every 60,000 miles on FB engines. WRX/STI 2.5L turbo: 30,000 miles due to higher cylinder pressures and EGT.

Estimated cost — typical U.S. ranges

Dealer

~$285–$390

Shop

~$200–$275

DIY

~$25–$100

Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.

Super Coolant

Every 30,000 mi

Subaru Super Coolant (blue): first change at 137,500 miles or 11 years, then every 30,000 miles. Do not substitute green or orange — head gasket sealing chemistry depends on the formula.

Estimated cost — typical U.S. ranges

Dealer

~$285–$330

Shop

~$200–$235

DIY

~$25–$60

Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.

Recommended maintenance

Extends the life of your vehicle and improves comfort

Cabin Air Filter

Every 15,000 mi

Replace cabin air filter every 15,000 miles. Behind the glove box on most Subaru models.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.
