2022 Subaru WRX Maintenance Schedule
The 2022 WRX launched the all-new VB generation with the 2.4L turbocharged FA24 boxer, replacing the previous 2.0L FA20 and bringing more torque. It paired the engine with a new high-torque CVT — the Subaru Performance Transmission (SPT) — which replaced the earlier WRX's Sport Lineartronic CVT rather than introducing a CVT for the first time. Because the FA24 is a turbocharged, direct-injection engine, disciplined oil changes and clean airflow matter more than on a naturally aspirated Subaru. This schedule follows Subaru's factory intervals; most WRX owners drive under the 'severe' definition (short trips, spirited driving, cold starts), so shorter oil intervals are the safer default. Note the engine is timing-chain driven, so there is no timing belt service to budget for.
Service Intervals
| Service | Interval | Est. Cost |
|---|---|---|
| Engine Oil & Filter0W-20 full synthetic. Subaru specifies 6,000 mi / 6 months, but many owners shorten to ~3,750 mi under hard or track use since the turbocharged FA24 is sensitive to oil condition. | 6,000 mi / 6 mo | $80-$130 |
| Tire Rotation & InspectionSymmetrical AWD demands even tread depth across all four corners; mismatched wear can bind the center differential and stress the driveline. | 6,000 mi / 6 mo | $40-$70 |
| Brake Fluid FlushSubaru calls for fresh brake fluid every 30,000 mi or 30 months; moisture-laden fluid fades under repeated hard braking and corrodes ABS/VDC hydraulics. | 30,000 mi / 30 mo | $90-$150 |
| Spark PlugsIridium plugs on a 60,000 mi interval; the turbocharged FA24 misfires and loses boost response quickly on worn or incorrectly gapped plugs. | 60,000 mi | $150-$250 |
| Engine Air FilterA clean filter protects the turbocharger and preserves boost; replace sooner in dusty climates or after track days. | 30,000 mi | $40-$70 |
| Cabin Air FilterSimple glovebox-access filter; clogging reduces HVAC airflow and can fog the windshield in humid weather. | 12,000 mi / 12 mo | $30-$60 |
| Transmission Fluid (SPT/CVT or 6-Speed Manual)The SPT is a high-torque CVT; Subaru labels its fluid long-life, but exchange near 60,000 mi (sooner if tracked) protects the valve body. Manual cars use 75W-90 gear oil on a similar interval. | 60,000 mi | $200-$400 |
| Front & Rear Differential Gear OilUnder Subaru's severe schedule the front and rear diffs get fresh gear oil around 30,000 mi; AWD hardware runs hot under spirited driving. | 30,000 mi | $120-$200 |
| Engine Coolant (Subaru Super Coolant)Factory-fill Super Coolant is good for the first ~137,500 mi / 11 years, then every ~75,000 mi / 6 years thereafter. | 137,500 mi / 132 mo | $120-$180 |
| Brake Pads & Rotor InspectionInspect pad thickness and rotor condition; hard driving and the car's weight can wear front pads by 30,000-45,000 mi. | 20,000 mi | $60-$100 |
2022 Subaru WRX Oil Change Interval
The 2022 Subaru WRX oil change interval is every 6,000 miles or 6 months, whichever comes first (estimated cost $80-$130). 0W-20 full synthetic. Subaru specifies 6,000 mi / 6 months, but many owners shorten to ~3,750 mi under hard or track use since the turbocharged FA24 is sensitive to oil condition.
What Happens If You Skip It
- Stretching oil changes on the turbocharged FA24 accelerates turbo bearing wear and oil coking, risking a $1,500-$2,500 turbocharger replacement.
- Skipping brake fluid flushes lets absorbed moisture boil under repeated hard stops, causing a soft pedal and eventual corrosion of the ABS/VDC unit.
- Neglecting differential and AWD fluid service leads to whining, gear wear, and driveline binding that can escalate into costly center-diff or differential repairs.
- Ignoring worn spark plugs on the direct-injection turbo engine causes misfires, rough boost delivery, and can foul ignition coils, hurting both performance and fuel economy.
- Running the SPT/CVT on old fluid promotes overheating and valve-body wear, and a failed CVT is a $4,000+ replacement far exceeding the cost of a fluid exchange.
- Letting intake-valve carbon accumulate without cleaning on this direct-injection engine causes hesitation, misfires, and eventually an $800-$1,200 walnut-blasting service.
Common Issues at Higher Mileage — 2022 Subaru WRX
Early VB cars showed Starlink 11.6-inch infotainment freezes, reboots, and Apple CarPlay dropouts; most are resolved by software updates at the dealer.
Front-tire wear runs fast on AWD summer/performance tires; skipped rotations produce uneven wear and steering-wheel vibration.
Direct-injection intake-valve carbon buildup begins to cause rough idle and cold-start stumble; periodic intake cleaning or walnut blasting restores smoothness.
Wheel-bearing hum is a known Subaru weak point; a growl that changes with cornering load usually points to a front bearing.
Clutch wear and shudder appear early on manual cars driven hard or launched aggressively; slipping under boost signals a worn disc.
Some FA-series boxers develop measurable oil consumption; check the dipstick between changes and top up with the correct 0W-20.
Suspension bushings and control-arm components loosen on rougher roads, producing clunks and vague steering that warrant a chassis inspection.
