Subaru Forester: Best and worst years for reliability
The most reliable Subaru Forester model years are 2016 through 2018 and 2020 to 2024, while the years to avoid are 2003–2010 and 2014–2015. Reliability ratings for the Forester vary significantly by generation, primarily due to mechanical shifts in engine design and transmission technology. While newer models offer advanced safety and better fuel economy, earlier versions are often cited for specific, costly engine defects.
Years to Avoid
- 2003–2010: These models are prone to head gasket failure, which typically occurs near the 100,000-mile mark and requires an expensive engine teardown to repair.
- 2014–2015: These years are known for excessive oil consumption and issues with the Continuously Variable Transmission (CVT), including shuddering and premature failure.
- 2019: As the first year of a new redesign, this model had frequent reports of windshield cracking and electrical issues related to battery drainage.
Most Reliable Years
- 2016–2018: These represent the final years of the fourth generation; Subaru resolved the majority of the oil consumption and CVT issues by this time.
- 2020–2024: These fifth-generation models have consistently high reliability scores from Consumer Reports, featuring a more refined powertrain and fewer mechanical complaints.
Key Issues by Generation
| Generation | Years | Primary Concerns |
|---|---|---|
| 2nd Gen | 2003–2008 | Engine head gasket leaks, timing belt failure |
| 3rd Gen | 2009–2013 | High oil consumption (2011+), head gaskets (2009-10) |
| 4th Gen | 2014–2018 | CVT transmission issues, suspension bushings |
| 5th Gen | 2019–Present | Windshield durability, thermal control valve (2019-21) |
Maintenance Tip: If purchasing a used Forester from the 2011–2015 range, verify if the vehicle underwent the manufacturer’s oil consumption test or had the piston rings replaced under warranty.
