What happens if you skip it
- Skipping CVT fluid changes leads to transmission slipping, overheating, and potential $3,000–$5,000 replacement costs by 100,000 miles.
- Neglecting tire rotation on AWD accelerates uneven wear and forces the CVT and differentials to compensate, reducing drivetrain lifespan.
- Delaying brake fluid flushes allows moisture to corrode brake lines and reduce stopping power, especially in humid climates.
- Missing differential fluid changes causes gear noise, whining, and eventual bearing failure in the front and rear differentials.
- Skipping spark plug replacement at 60,000 miles increases misfires and reduces fuel economy.
- Ignoring coolant flushes allows corrosion in the aluminum engine block, risking head gasket failure—a known Subaru weak point.
Common issues at higher mileage
- 60,000+ mi
- CVT shuddering or hesitation during acceleration; fluid degradation is the primary cause and requires immediate fluid change.
- 80,000+ mi
- Head gasket seepage or coolant loss (far less common on the FB25 than older EJ-series Subaru engines); monitor coolant level closely.
- 100,000+ mi
- Timing chain rattle on cold starts; while chains rarely break, noise indicates wear and warrants inspection by a Subaru specialist.
- 90,000+ mi
- Differential whining or grinding in turns; worn bearings or low fluid are common; check differential fluid level and condition.
- 120,000+ mi
- Transmission hesitation or delayed engagement; worn CVT pulleys and belts require professional diagnosis and possible rebuild.
Common questions about the 2020 Subaru Forester
How often does a 2020 Subaru Forester need an oil change?
GarageHub estimates the 2020 Subaru Forester oil change interval at every 6,000 mi or 6 months, whichever comes first (estimated cost $35-$75); this is not the manufacturer's figure, so check your owner's manual.
What maintenance does a 2020 Subaru Forester need?
GarageHub's estimate of the services not to skip on a 2020 Subaru Forester: engine oil & filter every 6,000 mi / 6 mo; brake fluid inspection & flush every 24 mo; brake pads & rotor inspection every 30,000 mi; cvt fluid (lineartronic transmission) 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 Forester at higher mileage?
What owners report as the miles add up — 60,000+ mi: CVT shuddering or hesitation during acceleration; fluid degradation is the primary cause and requires immediate fluid change. 80,000+ mi: Head gasket seepage or coolant loss (far less common on the FB25 than older EJ-series Subaru engines); monitor coolant level closely. 100,000+ mi: Timing chain rattle on cold starts; while chains rarely break, noise indicates wear and warrants inspection by a Subaru specialist. 90,000+ mi: Differential whining or grinding in turns; worn bearings or low fluid are common; check differential fluid level and condition. 120,000+ mi: Transmission hesitation or delayed engagement; worn CVT pulleys and belts require professional diagnosis and possible rebuild.
