Subaru is recalling 47,419 model-year 2010-13 vehicles due to a problem with the remote start system, according to the National Highway Traffic Safety Administration.
The affected vehicles use an Audiovox remote engine starter accessory and either a continuously variable automatic transmission or an automatic transmission. They include model-year 2010-13 Outbacks and Legacys, 2012-13 Imprezas and 2013 XV Crosstreks.
If the key fob is dropped, it could malfunction and randomly start the engine and continue to start and stop it until the battery in the fob is depleted or the car runs out of gas. According to Subaru, original equipment keyless entry fobs integrated on the vehicle key are not affected.
Subaru will notify owners starting in April, and dealers will replace the affected key fobs for free. Owners can call Subaru at 800-782-2783 or NHTSA's vehicle safety hotline at 888-327-4236 for more info.
