How Subaru schedules service

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.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE (PCV)

Campaign #19V744000 · Oct 17, 2019

Issue: Subaru of America, Inc. (Subaru) is recalling certain 2017-2018 Impreza and 2018 Crosstrek vehicles equipped with an aluminum Positive Crankcase Ventilation (PCV) valve. The PCV valve may come apart, allowing the separated components to enter the engine, possibly resulting in a loss of power while driving.

Risk: An unexpected loss of power while driving can increase the risk of a crash.

Fix: Subaru will notify owners, and dealers will inspect and, if necessary, replace the PCV valve, free of charge. If the PCV valve has separated and the components cannot be found, the engine will be replaced, free of charge. The recall began December 2, 2019. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WUP-01.

Issue: Subaru of America, Inc. (Subaru) is recalling certain 2018-2019 Subaru Crosstrek, 2019 Crosstrek Hybrid, and 2019 Forester vehicles. The rear stabilizer bracket bolts may loosen and detach.

Risk: Missing bolts may allow the rear stabilizer bracket to shift, increasing the risk of a crash.

Fix: Subaru will notify owners, and dealers will retorque and replace any missing bolts, free of charge. Owner notification letters were mailed May 17, 2021. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WRD-21.

Issue: Subaru of America, Inc. (Subaru) is recalling certain 2017-2019 Subaru Impreza and 2018-2019 Crosstrek vehicles. The Engine Control Module (ECM) may continue to power the ignition coil after the engine is shut off, causing a short circuit.

Risk: A short circuit in the ignition coils may cause a stall, increasing the risk of a crash.

Fix: Subaru will notify owners, and dealers will update the ECM software, replace the ignition coils and, if necessary, the front exhaust pipe, free of charge. Owner notification letters were mailed beginning June 1, 2021. Owners can contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WRE-21. Note: This recall includes all vehicles previously repaired under Recall 19V743.

ELECTRICAL SYSTEM:SOFTWARE

Campaign #19V743000 · Oct 18, 2019

Issue: Subaru of America, Inc. (Subaru) is recalling certain 2017-2019 Impreza and 2018-2019 Crosstrek vehicles. The Engine Control Module (ECM) may continue to power the ignition coil after the engine is shut off, which could result in a short circuit and blown fuse.

Risk: If a short circuit occurs while driving, the vehicle may stall, increasing the risk of a crash.

Fix: Subaru will notify owners, and dealers will update the ECM software and inspect and replace the ignition coil, as necessary, free of charge. In addition, on vehicles with confirmed ignition coil damage and a certain stored diagnostic trouble code (DTC), Subaru will replace the front exhaust pipe, free of charge.

SERVICE BRAKES

Campaign #17V701000 · Jul 11, 2017

Issue: Subaru of America, Inc. (Subaru) is recalling certain 2018 Crosstrek vehicles. These vehicles may be equipped with an incorrect floor mat retention bracket, allowing the floor mat to move out of position and interfere with the accelerator or brake pedal operation.

Risk: If the floor mat moves out of position and interferes with the accelerator or brake pedal operation, it can increase the risk of a crash.

Fix: Subaru has notified owners, and dealers will inspect the floor mat retention bracket and replace it if necessary, free of charge. The recall began November 14, 2017. Owners may contact Subaru customer service at 1-800-782-2783. Subaru's number for this recall is WTR-77.

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.
