(USA TODAY) -- General Motors is recalling nearly 200,000 mid-size SUVs because the master power door and window module in the driver's door can short out and catch fire.
Because the risk is serious enough -- and can happen when the truck is not in use -- GM says owners should park the truck outdoors until the module is repaired, according to documents posted by the National Highway Traffic Safety Administration.
The recalls expands a GM recall last August of 249,260 of the same trucks, but only those sold or registered in 20 Snow Belt states where salt is used on the roads.
The recall covers the remaining 193,652 of the mechanically similar 2006 and 2008 SUVs sold under five nameplates:
* 2006-07 Chevrolet Trailblazer, GMC Envoy, Buick Rainier, Saab 9-7x and Isuzu Ascender
* 2006 Chevrolet Trailblazer EXT and GMC Envoy XL
In the new action, GM also is recalling more than 38,000 of the trucks in use outside the U.S.
The problem is one that has prompted several recalls by multiple makers over the years -- moisture gets into the driver's door and corrodes the connections and electronics in the module that controls power locks and all the power windows.
That can cause a short circuit and overheating, which can lead to an electrical melting smell, smoke from the door or, worst case, a fire. As of last August, GM knew of 27 incidents and no injuries. The documents did not specify the number of complaints or incidents.
GM is notifying owners and dealers will check the module. If it's working, they'll put a moisture protection coating on the electronics; if not, they will replace it.
