Is the 2010 Subaru Legacy a bad year?
151 owner complaints to NHTSA. Transmission complaints: 50, 5× a quiet Legacy year.
Keep it, but watch the transmission
The transmission draws 5× the complaints of a quiet Legacy year, spread over 63k–138k miles, so there's no single mileage to plan around.
The verdict moves with mileage: the same car reads differently at 30,000 and at 150,000 miles.

Recalls for the 2010 Subaru Legacy: 18
These vehicles had their passenger frontal air bag inflators previously replaced under a prior recall using inflators of the same design. The inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling. An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.

The inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling. An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
The ball spring inside the switch may break, reducing the strength of the ignition switch. If this occurs, the weight on the key ring and certain road conditions could cause the ignition switch to move out of the run position to the accessory position, turning off the engine. The engine turning off unexpectedly can increase the risk of a crash. If a crash occurs under this condition, the air bag may not deploy, increasing the risk of injury.
These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. An explosion of an inflator within the passenger frontal air bag module may result in sharp metal fragments striking the front seat passenger, driver or other occupants resulting in serious injury or death.

The electronic parking brake (EPB) may not engage as intended, allowing the vehicle to rollaway if the transmission is not in the proper gear when parked. A vehicle rollaway can increase the risk of a crash.

These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules, and used as original equipment or replacement equipment. An inflator rupture may result in metal fragments striking the vehicle occupants resulting in serious injury or death.
Due to contamination, components within the windshield wiper motor bottom cover may interfere with each other. If an obstruction, such as a buildup of snow or ice prevents the wiper arms from being able to stop in the parked position, the wiper motor may overheat and the bottom cover may melt. If the windshield wiper motor overheats, the wipers may fail, reducing driver visibility and increasing the risk of a crash. Additionally, the wiper motor cover may melt, increasing the risk of a fire.

If the RES fob is dropped, the fob may malfunction and randomly transmit an engine start request without pressing the button. The engine may inadvertently start and run for up to fifteen minutes. The engine may continue to start and stop until the fob battery is depleted, or until the vehicle runs out of fuel.
Up to 78,650 of these vehicles may have been equipped with accessory puddle lights that, when illuminated, brighten the area under the doors of the vehicle. Over time, migration of the moisture into the circuit board and/or into the connector cavity, may result in a short circuit of the puddle light system. This may generate heat which may melt the plastic resulting in smoke or fire.
Due to a programming error, a lubrication hole within the 6-SPEED manual transmission was omitted. If the transmission gears are not properly lubricated, a groaning sound may begin to develop alerting the driver of a problem.
The wiring in the steering column electrical roll connector located behind the vehicle's steering wheel may develop stress cracks and eventually break. If this were to happen certain electrical components may not operate as intended. Possible circuits affected are the driver's frontal airbag, paddle shifter function, cruise control, horn control and radio functions increasing the risk of a crash.
A crack or split can occur in the CVT cooler hose resulting in a fluid leak. If the fluid is completely leaked during driving, the vehicle will come to a stop, possibly resulting in a crash.
