Best Model Years

2019, 2020, 2021, 2022 (part of the SK generation, which saw significant improvements)

Years to Avoid

Biggest Strengths

  • Exceptional safety features (EyeSight)
  • Standard Symmetrical All-Wheel Drive
  • Robust and fuel-efficient Boxer engine

Top Risk Areas

The systems that tend to fail first on the 2021 Subaru Forester, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.

1
Transmission (CVT)major~60,000-100,000 mi

While generally reliable, the Lineartronic CVT can develop issues like shuddering, delayed engagement, or eventual failure if the fluid is not changed proactively. Subaru often specifies 'inspection' rather than 'replacement,' leading so…

2
Catalytic Convertermajor~80,000-120,000 mi

Subaru engines, historically, can be susceptible to catalytic converter issues, often exacerbated by minor oil consumption or misfires. While less prevalent in the FB25D engine, premature catalytic converter failure can still occur, lead…

3
Electrical/Infotainment Systemmoderate~15,000-60,000 mi

Owners frequently report minor annoyances such as the infotainment system freezing, Apple CarPlay/Android Auto disconnecting, or occasional Bluetooth issues. Less commonly, HVAC blower motors can fail prematurely, leading to no cabin fan…

Full repair-cost ranges, fix-before-you-buy notes, and inspection checklists are in the report.

2021 Subaru Forester Mileage Danger Zones

The mileage windows when the 2021 Subaru Forester most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.

30,000

Low Risk Zone

At this mileage, the vehicle is still relatively new. Focus on routine oil changes, tire rotations, and cabin/engine air filter replacements. This is also a good time to get any minor infotainment glitches addressed under warranty.

60,000

Maintenance Zone

This mileage often marks a significant service interval. Proactive CVT fluid replacement is highly recommended, regardless of official service schedules, to ensure long-term transmission health. Spark plugs, brake inspection, and suspens…

90,000

Elevated Risk Zone

Beyond 90k miles, wear items become more prominent. Expect to evaluate suspension components like control arm bushings, further brake service, and potentially the catalytic converter, especially if check engine lights appear. Continued d…

120,000+

High Risk Zone

At this point, you're entering the territory where major component failures, if not properly maintained, are most likely. A neglected CVT could fail, and the engine may show signs of wear or minor leaks. Budget for potential larger repairs.

2021 Subaru Forester Ownership Cost Outlook

What it typically costs to keep the 2021 Subaru Forester on the road. Full 5-year cost-of-ownership projection and major-failure-risk forecast are in the report.

Annual Maintenance

$500-700

Moderate Repairs

$600-1,800 occasionally (e.g., CVT fluid service, catalytic converter, suspension work)

How Long Does the 2021 Subaru Forester Last?

Proactive maintenance is the cornerstone of Forester reliability. Don't strictly follow Subaru's 'inspect' guidance for CVT fluid; instead, plan for a fluid replacement every 60,000 miles to safeguard the transmission. Regular oil level checks are also critical.
