Overview
The 2010 Subaru Legacy is a midsize sedan (also offered as the Legacy Outback wagon in this era, but the Legacy nameplate here refers to the sedan) known for standard Symmetrical All-Wheel Drive and a confident, all-weather driving feel. For 2010, the Legacy entered a fully redesigned fifth generation with a roomier cabin and a more comfort-focused ride than earlier models. It’s ideal for commuters in snow-belt states, small families, and drivers who want AWD without moving to an SUV. In the market, it competes with the Honda Accord and Toyota Camry, but stands out by offering AWD across the lineup.
Key Features
1) Standard Symmetrical All-Wheel Drive across all trims, a key reason many buyers choose the Legacy for winter traction and stability.
2) Engine options: a 2.5-liter horizontally opposed (boxer) 4-cylinder (commonly around 170 hp) or an available 3.6-liter 6-cylinder (often listed around 256 hp) for stronger acceleration and smoother power delivery.
3) Transmission choices typically include a 6-speed manual on select 2.5i models, a CVT automatic on many 4-cylinder trims, and a 5-speed automatic paired with the 3.6R.
4) Safety and structure upgrades with the redesign, along with a more spacious rear seat and a comfortable, long-distance-friendly ride quality.
5) Available upscale and tech features by trim, including leather seating, a power moonroof, and upgraded audio/navigation on higher packages.
Common Issues & Reliability
Shoppers researching 2010 Subaru Legacy reliability and 2010 Subaru Legacy problems should know that this model can be a solid long-term car when maintained, but there are a few recurring complaints to watch for.
1) Excessive oil consumption (primarily 2.5L 4-cylinder): Some owners report the engine using oil between changes, sometimes becoming noticeable around 60,000–120,000 miles. If oil level isn’t monitored, it can contribute to low-oil running and accelerated engine wear. Not every car is affected, but it’s one of the most discussed 2010 Subaru Legacy common issues.
2) CVT concerns (4-cylinder automatic models): The Lineartronic CVT can develop drivability issues such as shuddering, hesitation, or unusual whining. Problems may show up anywhere from 80,000–150,000 miles depending on use and fluid condition. A healthy test drive should feel smooth and consistent with no flare, jerk, or delayed engagement.
3) Wheel bearing noise: A humming or growling sound that changes with speed is a common sign. Owners often report front or rear wheel bearing replacement in the 70,000–130,000 mile range, especially in areas with rough roads or heavy winter salt exposure.
4) Suspension and brake wear items: Clunks over bumps can point to worn sway bar links or control arm bushings, and warped brake rotors can cause pedal pulsation during stops. These are typical wear issues, but they come up frequently enough to be worth checking during inspection.
