Subaru Forester Years to AvoidThe weakest years — and the one you should buy instead
After reviewing every Subaru Forester we've analyzed (28 years), these are the 3 weakest. Each one has either an absolute low KeepScore, chronic repair issues, or unusually high ownership costs relative to other Forester years.
Proceed with caution
1998 Subaru Forester
The 1998 Subaru Forester is a highly capable and practical compact SUV, beloved for its legendary Symmetrical All-Wheel Drive, but it carries a significant reliability Achilles' heel with its engine's head gaskets. While the rest of the vehicle is generally robust for its age, buyers absolutely must verify head gasket service history to avoid a major and costly repair, transforming a potentially excellent value into a financial headache.
Why this year scores low
The EJ25D 2.5L DOHC engine is widely known for premature head gasket failure, often leading to external oil leaks, coolant leaks, and internal coolant consumption. Neglecting this leads to overheating and engine damage.
Common in areas with road salt, rust affects rear wheel arches, subframes, suspension components, brake lines, and fuel lines, compromising structural integrity and safety.
Aging wiring and sensors, particularly oxygen sensors and crankshaft/camshaft position sensors, can cause rough running, check engine lights, and reduced fuel economy. Power window regulators also commonly fail.
Proceed with caution
2001 Subaru Forester
The 2001 Subaru Forester offers remarkable utility and legendary Symmetrical All-Wheel Drive, making it a capable and versatile compact SUV. However, its reliability hinges entirely on the condition of its critical engine components, specifically the head gaskets. For the prepared owner, it remains a fantastic value, but bypassing a thorough pre-purchase inspection could lead to significant financial regret.
Why this year scores low
The 2.5L SOHC EJ25 engine is notorious for external oil leaks or internal coolant leaks (or both) from the head gaskets. This can lead to coolant consumption, overheating, or oil contamination.
Critical wear item including the belt, water pump, and idlers. Failure to replace at specified intervals (typically 105,000 miles) can lead to catastrophic engine damage.
These are common wear items that fail, often presenting as a humming or grinding noise from the rear. While not critical, they require replacement for safety and comfort.
Proceed with caution
2005 Subaru Forester
The 2005 Subaru Forester stands as a highly capable and practical compact SUV, renowned for its symmetrical all-wheel-drive system and sturdy construction. However, its otherwise solid reputation is marred by the prevalent head gasket issues common to its 2.5L engine, which necessitates a cautious approach for any prospective owner. With proper, proactive maintenance and a thorough pre-purchase inspection focused on these known weak points, this Forester can still offer many years of reliable, adventurous service.
Why this year scores low
The 2.5L SOHC EJ25 engine (non-turbo) is highly prone to external oil leaks and internal coolant leaks from the cylinder head gaskets. This can lead to coolant loss, overheating, and oil contamination, eventually causing catastrophic engine damage if ignored.
The timing belt, tensioners, idlers, and water pump are critical components requiring replacement at specific intervals (typically 105,000 miles). Failure to do so can result in belt breakage, leading to severe engine damage due to valve-piston collision.
In regions exposed to road salt, the rear subframe, control arms, brake lines, and fuel lines are susceptible to significant corrosion. This can compromise structural integrity, brake performance, and lead to costly repairs for rusted components.
