This week, Subaru recalled 47,419 of its Legacy, Outback, Impreza, and models because they could start themselves without human intervention.
An article on CNN.com reports that if the key fob with remove engine start is dropped, it could malfunction and send a message to the engine to start on its own, without pressing the remote start button.
The recall includes Legacy, Outback and Impreza models produced from 2010 to 2013 and also includes Crosstrek models from 2013.
In a letter to the National Highway Traffic Safety Administration, Subaru said, “The engine may inadvertently start and run for up to 15 minutes. The engine may continue to start and stop until the fob battery is depleted 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.”
The recall begins at the end of April. Owners can get their key fobs replaced by dealers, free of charge.
