Subaru Outback Years to AvoidThe weakest years — and the one you should buy instead
After reviewing every Subaru Outback we've analyzed (31 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 Outback years.
Proceed with caution
1996 Subaru Outback
The 1996 Subaru Outback offers legendary all-wheel-drive capability and utility, making it a compelling choice for outdoor enthusiasts. However, its significant Achilles' heel is the prevalent engine head gasket issue, demanding diligent pre-purchase inspection and budget allocation for preventative maintenance. Proceed with caution, but with the right care, it can be a highly rewarding vehicle.
Why this year scores low
External oil leaks or internal coolant/oil mixing from failed multi-layer steel (MLS) head gaskets. Leads to overheating, loss of power, and potential catastrophic engine damage if neglected.
Common leaks from the power steering pump, high-pressure lines, or rack and pinion. Can lead to a noisy pump, loss of assist, and expensive repairs if allowed to run dry.
Wear and tear on front and rear control arm bushings, strut mounts, and sway bar links. Results in clunking noises, reduced handling, and accelerated tire wear.
Proceed with caution
1998 Subaru Outback
The 1998 Subaru Outback is a practical, go-anywhere wagon, but its specific engine generation presents a significant reliability hurdle. While its AWD system and versatility are compelling, only proceed with caution and a thorough pre-purchase inspection focusing on the notorious head gaskets and potential rust issues. Ignoring these can quickly turn an affordable purchase into an expensive burden.
Why this year scores low
The 2.5L EJ25 Phase I engine is prone to external head gasket leaks (oil and coolant) and internal failures, leading to overheating, mixing fluids, and eventual engine damage. This is the single biggest issue for this model.
Subframes, brake lines, fuel lines, rocker panels, and rear wheel arches are highly susceptible to severe rust, especially in areas using road salt. This compromises structural integrity and safety.
Ball joints, control arm bushings, tie rod ends, and steering rack leaks are common wear items, leading to loose steering, clunking noises, and compromised handling.
Proceed with caution
2001 Subaru Outback
The 2001 Subaru Outback is a capable and versatile AWD wagon, making it an appealing used vehicle. However, it requires careful scrutiny due to well-documented engine reliability concerns, primarily related to its head gaskets. If you find a well-maintained example with proof of specific critical repairs, it can still deliver reliable service; otherwise, prepare for significant potential costs.
Why this year scores low
The 2.5L SOHC EJ25 engine is notorious for external oil leaks and internal coolant leaks from the head gaskets. External leaks manifest as oil stains, while internal leaks can lead to overheating, misfires, and potential catastrophic engine damage if not addressed. This is a design flaw that was partially addressed in later generations.
Due to age and often exacerbated by oil burning from head gasket leaks, the catalytic converter can fail, triggering P0420 check engine light codes. Oxygen sensors (front and rear) are also common failure points, leading to poor fuel economy and emissions issues.
While not a failure, the timing belt in the 2.5L engine has a strict replacement interval of 105,000 miles or 105 months. Neglecting this maintenance leads to catastrophic engine failure (bent valves, piston damage) as it's an interference engine. The water pump, idlers, and tensioner are typically replaced concurrently.
