2012 Subaru Legacy: engine and transmission complaints

VERY HIGH COMPLAINT SIGNAL
66%
50 of 76 relevant owner complaints are about the engine, transmission or fuel system

66% of relevant owner complaints filed with NHTSA on the 2012 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 88% of the 1,230 model years we track (2010–2023).

Excludes 14 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 56%).

too few complaints

Manufacturers fix things mid-generation. A bad year next to a clean one is common; the fix usually arrived in between.

Cleaner alternatives

Same car, a better year

Other midsize sedans with no elevated signal in 2012

The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.

When the engine shuts off without warning, power steering and braking assist are lost, creating a serious risk of collision. This is a known issue document…
