The recall applies to certain 2006 and 2007 models of the Chevrolet Trailblazer, the GMC Envoy, the Buick Rainier, the Saab 9-7X and the Isuzu Ascender. According to the Michigan-based automaker only vehicles sold in Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin and the District of Columbia are affected by the problem.
A document posted on the website of the U.S. National Highway Traffic Safety Administration explains that the fires have been traced to the presence of salt and other chemicals used to clear the roads inside of the driver's door. The chemicals corrode the connections of the power window and power lock switches and can create a short circuit over time.
"A short may cause the power door lock and power window switches to function intermittently or become inoperative. The short may also cause overheating, which could melt components of the door module, producing odor, smoke, or a fire," said the automaker in a statement.
Over the last couple of years 28 owners have reported door fires as a result of the electrical bugs but there have been no injuries.
GM will replace the power window switch of all of the aforementioned SUVs, not just the ones located in northern states where salt and other chemicals are used during the winter. Owners of affected vehicles will be notified by mail.
