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%).
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.

POWER TRAIN,ENGINE12/23/2025
My 2012 Subaru Legacy experiences involuntary engine stalling when coming to a quick stop, such as in stop-and-go traffic or during sudden braking at intersections. 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…
Brakes malfunctioned and car spun out and hit deer

This does not say whether a particular car has an open, unrepaired recall. That depends on the VIN.
Before you buy a 2012 Subaru Legacy
Ask the seller whether the transmission has ever been repaired or replaced, and whether the car has shown shuddering, slipping, delayed or harsh shifts, or a whine at speed.
Drive it from a cold start and long enough to warm up. Many transmission faults hide once the car is warm.
Get an independent pre-purchase inspection from a mechanic you choose, and tell them to focus on the transmission.
16 recall campaigns on this model year. Whether a specific car still has one open depends on the VIN; the report checks that.
Ask for service records. A transmission already replaced under warranty is a different car from one that was not.
Have the VIN?Paste it and get the full report for that car. First report free, then a 30-day pass covers a whole car search.
