In early October, Fuji Heavy Industries issued a recall with the Japanese Ministry of Land, Infrastructure, Transport and Tourism for 4 models including the Subaru Legacy over a defect in the secondary air pump relay. It has now expanded the recall to the United States.
The recall is due potentially insufficient pressing force on a contact point inside the relay that controls the emissions prevention secondary air pump. When this contact point is turned on, it could cause an arc discharge and the welding could continue to be live. As a result, the pump motor could rotate and if the internal pressure rises and the pilot light comes on, the pump can get hot, leading to plastic parts eroding, offensive odors and smoke. There could be a fire in the worst-case scenario.
The United States National Highway Traffic Safety Administration has reported that it received a recall over the same defect from Subaru Of America. The recall applies to a total of 100,217 2007-2009 Subaru Legacy and Outback models, 2008-2014 Impreza models, and 2009-2013 Forrester models.
Subaru Of America is contacting owners of the effected vehicles. Secondary air pumps are being replaced at dealerships.
