Subaru Impreza Years to AvoidThe weakest years — and the one you should buy instead
After reviewing every Subaru Impreza we've analyzed (33 years), these are the 3 weakest. Each one has either an absolute low reliability score, chronic repair issues, or unusually high ownership costs relative to other Impreza years.
Proceed with caution
1994 Subaru Impreza
The 1994 Subaru Impreza, particularly with its all-wheel-drive system, offers tenacious traction and surprising durability for its age. However, its classic EJ-series engine head gasket failures and susceptibility to rust in northern climates prevent a full endorsement, making careful inspection and proactive maintenance absolutely crucial for a positive ownership experience.
Why this year scores low
The non-turbo EJ-series engines are notorious for external oil and coolant leaks from the head gaskets, eventually leading to overheating, mixing fluids, or catastrophic failure. This is often due to the original gasket material degradation.
Especially in regions with road salt, the rear wheel arches, rocker panels, subframe, and suspension mounting points are highly susceptible to severe rust. This can compromise structural integrity and make repairs difficult.
Due to age and often harder driving conditions associated with AWD, worn bushings, ball joints, tie rod ends, and leaky power steering racks are common. Struts can also wear out, impacting ride quality and handling.
Proceed with caution
2005 Subaru Impreza
The 2005 Subaru Impreza offers commendable all-wheel-drive capability and engaging driving dynamics, making it an attractive option for those facing adverse weather or seeking a sportier compact. However, its Achilles' heel remains the well-documented head gasket issues on the 2.5L naturally aspirated engine, requiring diligent pre-purchase inspection and a readiness to invest in preventative maintenance to avoid significant repair costs and ensure long-term reliability.
Why this year scores low
The 2.5L SOHC naturally aspirated EJ25 engine (non-WRX/STi) is highly prone to external or internal head gasket leaks. This manifests as oil weeping, coolant consumption, white smoke from exhaust, or engine overheating due to coolant entering combustion chambers. If neglected, it can lead to catastrophic engine damage.
The timing belt, tensioner, and idler pulleys are critical wear items, particularly on the DOHC turbo engines (WRX/STi) but also present on SOHC NA engines. Failure to replace these components on schedule (typically every 105,000 miles or 105 months) can result in snapped belts, bent valves, and complete engine destruction.
Subarus of this era, especially those in regions with heavy road salt use, are highly susceptible to rust. Common areas include rear wheel arches, subframes, suspension components, brake lines, and fuel lines. This can compromise structural integrity and lead to expensive repairs or safety issues.
Proceed with caution
1998 Subaru Impreza
The 1998 Subaru Impreza, especially models equipped with the EJ22 engine, offers a compelling all-wheel-drive package with a solid chassis that's hard to beat in its class for winter driving and spirited handling. While it's a capable and fun compact, its age brings significant reliability concerns like head gaskets (especially on the EJ25) and pervasive rust, making a pre-purchase inspection absolutely critical to avoid costly surprises.
Why this year scores low
The EJ25 DOHC engine in the 2.5RS models is notorious for internal and external head gasket failures, leading to coolant leaks, oil consumption, and potential overheating. The EJ22 is less severe but often develops external oil leaks. Causes include design flaws and material degradation over time.
Common in salt-belt regions, rust can aggressively attack rear wheel wells, rocker panels, subframes, fuel lines, brake lines, and suspension mounting points. This is a severe issue that can compromise safety and lead to costly repairs or render the vehicle unusable.
Due to age and typical driving conditions, rubber bushings in control arms, strut mounts, and sway bar links commonly degrade, leading to clunking noises, reduced handling, and accelerated tire wear. Power steering pumps are also known for leaks.
