Subaru of America is recalling more than 47,000 cars and SUVs with remote starters because the engines can start on their own.

The recall affects some Legacy and Outback cars from the 2010 to 2013 model years. Also covered are the Impreza from 2012 and 2013 and the XV Crosstrek from 2013.

Subaru says that if the key fob is dropped, it can malfunction and start the engine. The motor will run for up to 15 minutes, but could continue to start and stop until the car runs out of gas or the fob battery dies. If the cars are parked in a garage, there's a risk of carbon monoxide buildup.

The cars all have automatic or continuously variable transmissions. Subaru dealers will replace the fobs free of charge.

There was no mention of injuries related to the recall. Calls to Subaru early Thursday were not immediately returned.

Meanwhile, Ford is recalling 230,000 minivans in 20 cold-weather states and Washington, D.C., to fix rust problems that can cause the third-row seats to come loose.

The company says the recall affects Ford Freestar and Mercury Monterey minivans from the 2004 through 2007 model years. They were sold mainly in Canada and U.S. states where salt is used to clear roads in the winter.

Ford said Thursday that rust can weaken the mounting brackets that hold the removable seats to the van floor. The company says no crashes or injuries have been reported from the problem.

Dealers will install new seat mounting brackets, placing them outside of the area that can rust. They'll also install panels above the rear wheels to prevent water from entering, Ford spokeswoman Kelli Felker said. Owners will be notified of the recall by letter during the last week of March.

"The panels will protect that area so that it won't get any other exposure to corrosive elements," Felker said.

The U.S. National Highway Traffic Safety Administration began investigating the vans from the 2004 model year in December, and added 2005 through 2007 to the probe in April because they all have similar seat designs.

The recall covers 196,500 minivans in the U.S. and another 33,500 outside the U.S., mainly in Canada, Felker said.

Vans in Connecticut, Iowa, Minnesota, Ohio, Wisconsin, Delaware, Maine, Missouri, Pennsylvania, Maryland, New Hampshire, Rhode Island, Illinois, Massachusetts, New Jersey, Vermont, Indiana, Michigan, New York, West Virginia and Washington, D.C., are being recalled.
