2010 Subaru Legacy Recalls

Windshield Wipers Stop Working

The components within the windshield wiper motor bottom cover may interfere with each other due to contamination. This can cause the motor to overheat, fail to operate and result in a fire hazard. Dealers will replace the windshield wiper motor bottom cover assembly free of charge to resolve the concern.

The Engine May Start Unexpectedly

On 2010-2013 Subaru models equipped with an automatic transmission and Audiovox accessory remote start system, if the key fob is dropped it may begin randomly transmitting a request to start the engine, causing the engine to unexpectedly start and run for up to 15 minutes. The engine may continue to start and stop until the battery in the fob goes dead or until the vehicle runs out of fuel. If the vehicle is parked in an enclosed area, there is a risk of carbon monoxide build-up which may cause asphyxiation. Original equipment keyless entry fobs integrated on the vehicle key are not affected. Dealers will replace the affected key fobs to correct this concern.

Puddle Lights May Melt or Catch Fire

The accessory lights that illuminate the area under the doors are referred to as "puddle" lights. An electrical short circuit can develop when either the puddle light or its connector are exposed to an electrolytic moisture source (such as road spray that has road salt in it) and it penetrates the circuit board of the puddle light or the pins of the puddle light connector(s). The short circuit can generate heat which may melt the plastic resulting in smoke or fire. Subaru dealers will install an additional fused-harness, to protect the puddle light system.

2010 Legacy GT 6spd manual, 2nd Subaru ( last one was a 2002 WRX Wagon ). I am a HUGE Subie fan, and have enjoyed fantastic experiences with both vehicles. In fact, my mother now drives a 2008 Outback v6, my father 2013 Legacy Premium, my sister-in-law 2013 Forester. The Legacy GT offers a much more mature and sophisticated ride, plush comfortable interior, and upscale styling to the WRX's...
Purchased a 2010 legacy limited. this is my 2nd subaru and I love it. Nice solid feel to the whole car. Rides like a dream! The brakes are just a little softer than what I'm use to.Got the 3.6 engine and mostly do freeway driving and first tank I averaged 29.0 mpg. Great car.
