2010 Subaru Legacy problems: engine and transmission complaints and recalls
65% of relevant owner complaints filed with NHTSA on the 2010 Subaru Legacy are about the engine, transmission or fuel system. Well over half of everything owners reported is the drivetrain. That is a severe model-level pattern; every model year we track at this level has a documented failure behind it.
Worse than 87% of the 1,790 model years we track (2010–2023).
Excludes 38 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 49%).
Does the 2010 Subaru Legacy have transmission problems?
Owner complaints say yes, heavily, as a model-year pattern. 73 of 112 relevant complaints filed with NHTSA about the 2010 Subaru Legacy concern the engine, transmission or fuel system (65%), and the largest group is filed under power train (50). For comparison, the 2011 scores 54%. On a test drive, check for shuddering, slipping, delayed or harsh shifts, or a whine at speed. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.

Are there engine or transmission recalls on the 2010 Subaru Legacy?
Yes. NHTSA lists 2 recall campaigns on the 2010 Subaru Legacy involving the engine, transmission or fuel system, out of 18 in total. A recall is the manufacturer admitting a defect and paying to fix it; whether a specific car still has one open depends on its VIN, which the full report checks. The owner complaints above are a separate record and often point at problems that never became a recall.

Should I buy a 2010 Subaru Legacy?
That depends on the car in front of you, not just the model year. The 2010 Subaru Legacy has an elevated transmission complaint pattern, so treat it as a car that needs proof: service records showing transmission work, a cold-start test drive, and an independent pre-purchase inspection focused on the transmission. A well-kept or already-repaired example can be a fine car; an unknown one is a gamble.
