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.
ELECTRICAL SYSTEM:SOFTWARE

EXTERIOR LIGHTING:HEADLIGHTS
Campaign #22V624000 · Dec 8, 2022
Issue: Subaru of America, Inc. (Subaru) is recalling certain 2017-2019 Impreza vehicles. The left and right side reflex reflector and left side low beam reflector may inadequately reflect light. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
Risk: Reflectors that do not provide adequate illumination reduce the driver's ability to see and increase the risk of a crash.
Fix: Dealers will replace the front headlamp assemblies, free of charge. Owner notification letters were mailed November 15, 2023. Owners may contact Subaru's customer service at 1-844-373-6614. Subaru's number for this recall is WRG-22.
Critical for safety and preventing major damage
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.
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.
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.
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
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
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.
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.
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.
Keeps your vehicle running smoothly and efficiently
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.
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.
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.
Extends the life of your vehicle and improves comfort
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.
