2009 Subaru Forester: Buy or Avoid?
The 2009 Subaru Forester offers impressive all-weather capability and a reputation for safety, making it a compelling choice for many. However, prospective buyers must be acutely aware of a few significant engine-related vulnerabilities that can lead to costly repairs if neglected or unaddressed. Approach with caution and a thorough pre-purchase inspection to ensure you're getting a well-maintained example.
While the 2009 Subaru Forester is a capable and safe vehicle with an excellent AWD system, the well-documented head gasket issues on the naturally aspirated 2.5L engine demand a cautious approach. If you find one with documented head gasket replacement or are prepared to address it, it can be a good value. Otherwise…

2009 Subaru Forester — Known Trouble Spots
The systems that tend to fail first on the 2009 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.
The naturally aspirated 2.5L EJ253 engine is notorious for external head gasket leaks, typically manifesting as oil or coolant seepage. If not addressed, this can lead to overheating, misfires, or internal engine damage. While not as com…

2009 Subaru Forester Mileage Danger Zones
The mileage windows when the 2009 Subaru Forester most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Low Risk Zone
At this mileage, the Forester is still relatively new. Focus on routine oil changes, tire rotations, and general fluid checks. Address any minor issues under warranty if applicable.
Maintenance Zone
This is a critical service interval. Ensure spark plugs, air filter, fuel filter (if applicable), and all fluids (differential, transmission, coolant, brake) are changed. Keep a close eye on the engine for any signs of oil seepage around…
Elevated Risk Zone
Head gasket failure risk significantly increases for the naturally aspirated engine. Suspension components, including struts and bushings, are likely nearing the end of their service life. Be prepared for potential larger repairs.
High Risk Zone
Beyond 120,000 miles, the 2009 Forester enters a period where major component failures, particularly related to the engine (head gaskets, excessive oil consumption), are more probable. Budget for significant maintenance and potential rep…
2009 Subaru Forester Ownership Cost Outlook
What it typically costs to keep the 2009 Subaru Forester on the road. Full 5-year cost-of-ownership projection and major-failure-risk forecast are in the report.
Annual Maintenance
$400-600
Moderate Repairs
$500-1,500 occasionally
How Long Does the 2009 Subaru Forester Last?
Given the engine's vulnerabilities, a Forester with meticulously documented service records, especially confirming head gasket replacement or very low mileage, is preferable. Higher mileage examples (100k+) without this critical repair should be approached with a budget for immediate head gasket service.
