What happens if you skip it
- Neglecting CVT fluid changes can cause shuddering, slipping, and premature transmission failure requiring $4,000-$7,000 replacement.
- Delaying tire rotation on AWD models creates uneven tread wear that forces the CVT and differentials to work harder, risking expensive drivetrain damage.
- Skipping brake fluid flushes allows moisture buildup that corrodes ABS components and reduces braking performance in emergency stops.
- Ignoring spark plug replacement at 60,000 miles leads to misfires, poor fuel economy, and potential catalytic converter damage on the FB20 engine.
- Failing to change differential fluid causes increased wear on AWD components, leading to whining noises, vibration, and eventual differential failure.
- Overdue engine oil changes in the FB20 boxer engine accelerate piston ring wear and oil consumption, a known issue that worsens with neglect.
Common issues at higher mileage
- 60,000+ mi
- Excessive oil consumption may develop in FB-family engines due to piston ring design; monitor oil level between changes and address early under warranty extension if applicable.
- 80,000+ mi
- CVT judder or hesitation during acceleration can occur if fluid changes are delayed; early fluid service often prevents costly transmission replacement.
- 70,000+ mi
- Front wheel bearing noise (humming or grinding) is common in AWD Subarus; replacement typically needed at 70,000-100,000 miles depending on road conditions.
- 50,000+ mi
- Rear brake pads wear faster than fronts due to AWD weight distribution; inspect rears closely during routine brake checks.
- 100,000+ mi
- CV axle boots may crack and leak grease, leading to clicking noises during turns; inspect boots at every service and replace before joint damage occurs.
- 90,000+ mi
- Oxygen sensor failures can trigger check engine lights and reduce fuel economy; replacement is routine maintenance on high-mileage FB20 engines.
Common questions about the 2020 Subaru Impreza
How often does a 2020 Subaru Impreza need an oil change?
GarageHub estimates the 2020 Subaru Impreza oil change interval at every 6,000 mi or 6 months, whichever comes first (estimated cost $45-$75); this is not the manufacturer's figure, so check your owner's manual.
What maintenance does a 2020 Subaru Impreza need?
GarageHub's estimate of the services not to skip on a 2020 Subaru Impreza: engine oil & filter every 6,000 mi / 6 mo; tire rotation every 7,500 mi; brake fluid flush every 36 mo; brake pads & rotor inspection every 30,000 mi; cvt transmission fluid every 60,000 mi. These intervals are estimates, not the manufacturer's maintenance schedule. Check your owner's manual for the exact figures.
What goes wrong on a Subaru Impreza at higher mileage?
What owners report as the miles add up — 60,000+ mi: Excessive oil consumption may develop in FB-family engines due to piston ring design; monitor oil level between changes and address early under warranty extension if applicable. 80,000+ mi: CVT judder or hesitation during acceleration can occur if fluid changes are delayed; early fluid service often prevents costly transmission replacement. 70,000+ mi: Front wheel bearing noise (humming or grinding) is common in AWD Subarus; replacement typically needed at 70,000-100,000 miles depending on road conditions. 50,000+ mi: Rear brake pads wear faster than fronts due to AWD weight distribution; inspect rears closely during routine brake checks. 100,000+ mi: CV axle boots may crack and leak grease, leading to clicking noises during turns; inspect boots at every service and replace before joint damage occurs. 90,000+ mi: Oxygen sensor failures can trigger check engine lights and reduce fuel economy; replacement is routine maintenance on high-mileage FB20 engines.
