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.

BACK OVER PREVENTION:DISPLAY FUNCTION

Campaign #20V766000 · Oct 12, 2020

Issue: Subaru of America, Inc. (Subaru) is recalling certain 2020 Legacy and Outback vehicles equipped with "high" grade and "mid" grade multimedia navigation. The August 2020 over-the-air software update may have timed out without completing the installation, corrupting the data, and causing the rearview display to shutoff intermittently. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."

Risk: The intermittent loss of the rearview image reduces the driver's visibility and increases the risk of crash.

Fix: Subaru will notify owners, and dealers will reprogram the software and, if necessary, replace the Cockpit Control Module, free of charge. The recall began January 22, 2021. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WRH-20.

POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM)

Campaign #21V955000 · Sep 12, 2021

Issue: Subaru of America, Inc. (Subaru) is recalling certain 2019-2020 Ascent, 2020 Legacy and Outback vehicles. A programming error in the Transmission Control Unit (TCU) may allow the clutch to engage before the drive chain is completely clamped.

Risk: An improperly secured drive chain may slip and break, causing a loss of drive power and increasing the risk of a crash.

Fix: Dealers will reprogram the TCU, inspect TCU data for chain slip, and visually inspect the chain guide. If evidence of chain slippage or damage is found, the transmission will be replaced. Repairs will be performed free of charge. Owner notification letters were mailed August 19, 2022. This recall includes all vehicles previously recalled under 19V-855. Vehicles previously recalled under 19V-855 will need to have the new remedy performed for this recall once available. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WRK-21.

FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP

Campaign #21V587000 · Jul 29, 2021

Issue: Subaru of America, Inc. (Subaru) is recalling certain 2019-2020 Ascent, 2018 Forester, 2018-2020 Impreza, Legacy, Outback, 2018-2019 BRZ, WRX, and Toyota 86 vehicles. The low-pressure fuel pump inside the fuel tank may fail.

Risk: Fuel pump failure can cause an engine stall while driving, increasing the risk of a crash.

Fix: Dealers will replace the low-pressure fuel pump, free of charge. Owner notification letters were mailed September 24, 2021. Subaru and Toyota owners may call customer service at 1-844-373-6614. Subaru's number for this recall is WRG-21.

SERVICE BRAKES, HYDRAULIC:PEDALS AND LINKAGES

Campaign #19V664000 · Sep 18, 2019

Issue: Subaru of America, Inc. (Subaru) is recalling certain 2020 Outback and Legacy vehicles. The brake pedal mounting bracket may have a missing or insufficiently tightened bolt.

Risk: A missing or loose bolt may cause the brake pedal mounting area to deform over time, which can reduce braking performance and increase the risk of a crash.

Fix: Subaru will notify owners, and dealers will inspect the brake pedal mounting bracket hardware and replace the hardware or brake pedal assembly, as necessary, free of charge. The recall began October 1, 2019. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WUL-97.

POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM)

Campaign #22V485000 · Aug 7, 2022

Issue: Subaru of America, Inc. (Subaru) is recalling certain 2020-2021 Outback and Legacy vehicles. A programming error in the Transmission Control Unit (TCU) may allow the clutch to engage before the drive chain is completely clamped.

Risk: An improperly secured drive chain may slip and break, causing a loss of drive power and increasing the risk of a crash.

Fix: Dealers will reprogram the TCU, inspect TCU data for chain slip, and visually inspect the chain guide. If evidence of chain slippage or damage is found, the transmission will be replaced. Repairs will be performed free of charge. Owner notification letters are expected to be mailed August 24, 2022. Owners may contact Subaru's customer service at 1-844-373-6614. Subaru's number for this recall is WRK-22. This recall is an expansion of previous recall number 21V-955.

AIR BAGS:SENSOR:OCCUPANT CLASSIFICATION:FRONT PASSENGER

Campaign #24V227000 · Mar 22, 2024

Issue: Subaru of America, Inc. (Subaru) is recalling certain 2020-2022 Outback and Legacy vehicles. A capacitor in the sensors for the Occupant Detection System (ODS) may crack and short circuit, which can prevent the front passenger air bag from deploying in a crash.

Risk: An air bag that does not deploy during a crash can increase the risk of injury.

Fix: Dealers will replace the ODS sensors on the front passenger seat, free of charge. Owner notifications were mailed February 3, 2025. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WRA-24.

Recall data refreshed Jul 19, 2026.

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.
