After receiving seven complaints of the rear liftgate unexpectedly closing on 2009 Honda Odyssey minivans, the National Highway Traffic Safety Administration's Office of Defects Investigation is looking into the alleged defect.

The vehicles, Odyssey Touring and EX-L models, were equipped with a powered rear liftgate system. The complaints indicate that the gas-filled liftgate struts failed and were unable to support the liftgate when it was in the open position.

Two of the seven complaints reported injuries due to consumers being struck by the closing liftgate.

Thus far, there are no similar complaints on model year 2008 and 2010 Honda Odyssey vehicles that are also equipped with power liftgates.
