DETROIT >> Honda is recalling nearly 46,000 Odyssey minivans because the rear doors can fall on people unexpectedly, and have on at least two occasions.

The problem affects minivans from the 2008 and 2009 model years that have power lift gates.

The National Highway Traffic Safety Administration says on its website that gas can leak out of the struts that support the lift gates. The doors could close unexpectedly, increasing the risk of injuries.

Honda says the problem has caused two minor injuries. The company will replace both power liftgate struts for free.

Honda will send letters to van owners next month with instructions about the recall.

Owners with questions can call Honda at 1-800-999-1009.
