According to an article on CNNMoney.com, Subaru of America is recalling over 630,000 vehicles because water could get into lights on the side mirrors, possibly leading to a risk of fire.
The cars in the recall have “puddle lights,” or lights that shine down from underneath the doors to illuminate the ground at night when an occupant is entering or exiting the vehicle. But if the lights are exposed to “electrolytic moisture source”, most likely from water spray that contains road salts, the lights can short circuit, causing smoke or fire.
Models involved in the recall include certain 2009 to 2012 Subaru Forester SUVs, the 2010 to 2011 Legacy sedan, the 2010 to 2011 Outback wagon, and the 2006 to 2012 Tribeca SUV.
Subaru dealers are repairing the problem free of charge.
