2019 Subaru Impreza Maintenance Schedule
- Generation
- 5th generation (2017-2023)
- Engine
- 2.0L naturally aspirated flat-4 (FB20)
- Intervals
- 12
The 2019 Subaru Impreza (5th generation) features a 2.0L FB20 flat-4 engine with a timing chain, paired with either a 5-speed manual transmission or Subaru's Lineartronic CVT, and standard Symmetrical AWD. This schedule addresses the unique needs of the CVT transmission (where equipped), AWD system components, and the horizontally-opposed engine configuration that requires specific maintenance attention to prevent head gasket and oil consumption issues common to this platform.
Service Intervals
Where is your Impreza right now?
Type the odometer and the table below re-sorts by what's closest. It works from the reading alone — it can't see what you've already had done.
Est. costs are US-typical, in USD.
| Service | Interval | Est. Cost |
|---|---|---|
| Engine Oil & FilterSafety itemSubaru recommends 0W-20 synthetic oil; the FB20 flat-4 is sensitive to oil quality and level due to horizontal cylinder layout. | 6,000 mi / 6 mo | $45-$75 |
| Tire RotationSafety itemEssential for AWD system health; uneven tire wear can damage the CVT and center differential on Symmetrical AWD. | 7,500 mi | $25-$50 |
| Cabin Air FilterLocated behind glove box; affects HVAC performance and air quality in the cabin. | 12,000 mi / 12 mo | $20-$45 |
| Engine Air FilterSubaru specifies replacement at 30k miles under normal conditions; inspect more frequently in dusty environments. | 30,000 mi | $25-$50 |
| Brake Fluid FlushSafety itemSubaru mandates every 3 years regardless of mileage; hygroscopic fluid degrades braking performance and ABS function. | 36 mo | $80-$120 |
| Brake Pad Inspection & ReplacementSafety itemInspect at 30k intervals; typical pad life is 40k-60k miles depending on driving style and terrain. | 30,000 mi | $200-$400 |
| CVT Transmission FluidCVT models: Subaru does NOT require CVT fluid replacement under normal driving conditions (inspect-only). Replacement at 60k miles is specified only for severe/special operating conditions (towing, commercial use, mountain driving, dusty/muddy conditions). Many owners choose preventive replacement to extend CVT life. Manual transmission models: inspect at regular intervals. | 60,000 mi | $180-$280 |
| Engine Coolant FlushSubaru Super Coolant is rated for 11 years/137,500 miles on first fill; subsequent changes every 6 years/75k miles. | 137,500 mi / 132 mo | $120-$180 |
| Spark PlugsIridium plugs specified at 97,500 miles under normal service (60k miles under severe conditions); horizontal engine layout makes access more labor-intensive than inline engines. | 97,500 mi / 78 mo | $180-$280 |
| Rear Differential FluidInitial service at 30k miles, then every 30k under severe conditions (towing, mountain driving, extreme temps); normal use may extend intervals. Uses 75W-90 gear oil. | 30,000 mi | $80-$130 |
| Battery Inspection & ReplacementTypical lifespan 4-6 years; Eyesight system and electronics are sensitive to voltage drops. | 48 mo | $150-$250 |
| Valve Cover GasketsFB20 engines may develop oil seepage from valve covers at higher mileage; preventive replacement avoids oil leaks onto exhaust. | 100,000 mi | $400-$700 |
2019 Subaru Impreza Oil Change Interval
The 2019 Subaru Impreza oil change interval is every 6,000 mi or 6 months, whichever comes first (estimated cost $45-$75). Subaru recommends 0W-20 synthetic oil; the FB20 flat-4 is sensitive to oil quality and level due to horizontal cylinder layout.
What Happens If You Skip It
- Neglecting CVT fluid changes can lead to shuddering, slipping, and premature transmission failure; CVT replacements cost $4,000-$7,000.
- Uneven tire wear from skipped rotations will damage the AWD system's center differential and potentially the CVT, requiring costly drivetrain repairs.
- Deferred oil changes accelerate oil consumption issues inherent to the FB20 engine, potentially causing piston ring damage and requiring engine rebuild.
- Ignoring brake fluid flushes degrades ABS and stability control performance, increasing stopping distances and compromising Eyesight safety features.
- Skipping differential services causes metal shavings to circulate, wearing AWD clutch packs and leading to binding or complete AWD failure.
- Delayed spark plug replacement causes misfires that can damage the catalytic converter ($1,200-$2,000 replacement) and trigger Check Engine lights.
Common Issues at Higher Mileage — 2019 Subaru Impreza
CVT judder or hesitation during acceleration, often resolved by fluid change or software update; some units require replacement under extended warranty.
Increased oil consumption between changes; FB20 engines may consume up to 1 quart per 1,200 miles, requiring frequent top-offs.
Valve cover gasket and cam carrier seepage causing oil smell and potential exhaust smoke; common on flat-4 engines due to horizontal orientation.
Rear wheel bearing noise or hum; AWD system places additional stress on bearings, particularly in harsh climates with road salt.
Eyesight camera calibration drift or windshield-mounted sensor issues requiring recalibration after windshield replacement or alignment changes.
Head gasket weepage may appear on some FB20 engines, though less common than older EJ-series; monitor coolant levels and watch for external leaks.
Common questions about the 2019 Subaru Impreza
How often does a 2019 Subaru Impreza need an oil change?
The 2019 Subaru Impreza oil change interval is every 6,000 mi or 6 months, whichever comes first (estimated cost $45-$75). Subaru recommends 0W-20 synthetic oil; the FB20 flat-4 is sensitive to oil quality and level due to horizontal cylinder layout.
What maintenance does a 2019 Subaru Impreza need?
The services not to skip on a 2019 Subaru Impreza: engine oil & filter every 6,000 mi / 6 mo; tire rotation every 7,500 mi; brake fluid flush every 36 mo; brake pad inspection & replacement every 30,000 mi. The table above lists every service with its interval and an estimated cost.
What goes wrong on a Subaru Impreza at higher mileage?
What owners report as the miles add up — 60,000+ mi: CVT judder or hesitation during acceleration, often resolved by fluid change or software update; some units require replacement under extended warranty. 80,000+ mi: Increased oil consumption between changes; FB20 engines may consume up to 1 quart per 1,200 miles, requiring frequent top-offs. 100,000+ mi: Valve cover gasket and cam carrier seepage causing oil smell and potential exhaust smoke; common on flat-4 engines due to horizontal orientation. 70,000+ mi: Rear wheel bearing noise or hum; AWD system places additional stress on bearings, particularly in harsh climates with road salt. 90,000+ mi: Eyesight camera calibration drift or windshield-mounted sensor issues requiring recalibration after windshield replacement or alignment changes. 120,000+ mi: Head gasket weepage may appear on some FB20 engines, though less common than older EJ-series; monitor coolant levels and watch for external leaks.
