Is the 2010 Subaru Legacy reliable?

It can be reliable with consistent maintenance, especially regular oil checks and timely fluid service, but buyers should be aware of potential oil consumption and CVT-related issues on higher-mileage cars.

What are the most common 2010 Subaru Legacy problems?

Frequently reported issues include oil consumption on the 2.5L engine, CVT shudder/whine or hesitation on 4-cylinder automatics, wheel bearing noise, and suspension/brake wear such as clunks or rotor vibration.

Are maintenance costs high for a 2010 Legacy?

Costs are usually moderate for a midsize AWD sedan, but repairs can become more expensive if a CVT develops problems or if oil consumption leads to engine-related work. Routine items like brakes, tires, and fluids are comparable to other AWD vehicles.

What are the best years of Subaru Legacy to buy?

Many shoppers look for years with strong maintenance history and fewer powertrain complaints; later years within a generation and well-documented service records tend to be the safest bet. For the Legacy overall, verifying the specific engine/transmission combination and service history matters more than the badge year alone.

What should I check before buying a used 2010 Subaru Legacy?

Review service records, confirm oil change intervals, check for signs of oil burning, and test drive for smooth CVT operation (or clean shifts on the 5-speed auto). Inspect for wheel bearing hum, suspension clunks, even tire wear, and ensure all four tires match closely in brand/model and tread depth.
