Overview

The 2008 Subaru Legacy is a midsize sedan (also offered as the Legacy wagon in some markets) known for standard all-wheel drive and confident all-weather handling. It’s a strong fit for drivers who want a practical daily commuter with secure traction, available turbo power, and a more “driver’s car” feel than many family sedans of its era. For 2008, the Legacy remained in the fourth generation (2005–2009), benefiting from the refinements Subaru made after the 2005 redesign. In the used market, it’s often cross-shopped with the Honda Accord and Toyota Camry, but stands out with AWD and a more planted road feel.

Key Features

1) STANDARD SYMMETRICAL ALL-WHEEL DRIVE: A major selling point for the 2008 Legacy is that AWD is standard across trims, making it appealing in snow and rain without stepping up to an SUV. 2) ENGINE OPTIONS: Most models use a 2.5-liter flat-four (boxer) engine, while certain trims offer a turbocharged 2.5-liter (often referred to as 2.5GT) for stronger acceleration. A 3.0-liter flat-six (3.0R) was also available on some models, offering smoother power delivery. 3) SAFETY AND STABILITY: Many 2008 Legacy models include strong crash-test performance for the era and available stability/traction control depending on trim and equipment. 4) COMFORT AND PRACTICALITY: A roomy back seat for a midsize sedan, a usable trunk, and supportive seating make it a solid choice for commuting and road trips. 5) DRIVING CHARACTER: Compared with many midsize competitors, the Legacy is often praised for steering feel, balanced handling, and composed highway manners, especially with AWD and the boxer engine’s low center of gravity.

Common Issues & Reliability

Shoppers researching “2008 Subaru Legacy problems,” “2008 Subaru Legacy reliability,” and “2008 Subaru Legacy common issues” will find the model can be dependable when maintained, but there are a few repeat trouble spots to know. 1) HEAD GASKET COOLANT/OIL LEAKS (2.5L NON-TURBO): The naturally aspirated 2.5L boxer is known for potential external head gasket seepage. Some owners report coolant smell, slow coolant loss, or oil residue around the engine at higher mileage, often around 90,000–140,000 miles, though it can vary widely. Not every car is affected, but it’s a key inspection point. 2) TURBO MODELS: OIL SUPPLY AND TURBO WEAR: On 2.5GT turbo models, oil quality and change intervals matter. Neglected oil changes can contribute to turbo wear, oil consumption, or bearing issues as mileage climbs (commonly reported after 100,000 miles on poorly maintained examples). Evidence of consistent oil service and proper warm-up habits is especially important here. 3) COOLING SYSTEM AND OVERHEATING RISK: Like many older vehicles, aging radiators, hoses, thermostats, and water pumps can become weak points around the 100,000–150,000 mile range. If the cooling system is not kept healthy, overheating can accelerate gasket or engine problems. 4) SUSPENSION AND WHEEL BEARINGS: Owners commonly report wear items such as wheel bearings, struts, and control arm bushings as the car ages. Symptoms include humming noises that rise with speed (wheel bearing) or clunks and loose steering feel over bumps (bushings/struts), often appearing after 90,000+ miles depending on roads and climate.
