Overview

The 2020 Subaru Forester is usually easy to live with, but wheel-end hum, tire noise confusion, and battery reserve complaints are the kinds of ownership issues that tend to get noticed first.

Common problems
These are the issues owners usually notice first before the repair turns into a bigger annoyance.
- Road-speed hum that gets blamed on tires before hub wear is confirmed
- Battery complaints after colder-weather starts or shorter-trip use
- Brake and suspension refinement issues that make the Forester feel older early
Fitment and model notes
Use these notes to avoid applying the same advice across trims, phases, or powertrains that behave differently.
Which trims this applies to
- Most 2020 Subaru Forester daily-driver trims in this generation.
When this does not apply
- Do not treat these notes as final fitment guidance for special trims, market-specific variants, or modified suspension setups without confirming the actual hardware.
Pre-facelift vs facelift differences
- Keep the SK-era Forester ownership pattern grouped while still requiring trim and package confirmation before parts are ordered.
Hybrid vs gas differences
- The broad ownership logic still applies, but exact diagnosis and part choice can change with drivetrain, wheel size, and package differences.
Recommended parts
These are the parts worth looking at first if you are trying to solve a common issue or stay ahead of wear.

View productMaintenance tips
These are the maintenance habits most likely to keep the common complaints from getting expensive.
- Separate tire noise from hub noise cleanly before ordering parts.
- Treat battery weakness early because cold-weather ownership makes the complaint more obvious fast.
- Keep tires rotated and matched because the Forester’s overall refinement depends on it more than people think.
