General Motors has issued a recall for 2011 and 2012 models of the Buick Enclave, Chevrolet Traverse, and GMC Acadia. However, the recall is limited to owners in northern states, since it's associated with problems with snow and ice buildup.
According to a bulletin from the National Highway Traffic Safety Administration, the recall of the Enclave, Traverse, and Acadia is linked to a problem with the nuts that hold the wiper arms in place. NHTSA says that the snow and ice can restrict the movement of the wiper arms, and over time, "the wiper arm may loosen and cause the wiper to become inoperative".
The recall affects owners in Alaska, Colorado, Connecticut, Delaware, Idaho, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Montana, Nebraska, New Hampshire, New Jersey, New York, North Dakota, Ohio, Pennsylvania, Rhode Island, South Dakota, Utah, Vermont, West Virginia, Wisconsin, Wyoming, and the District of Columbia. In all, 50,001 vehicles are included in the recall.
GM says that it will begin notifying owners of those vehicles about the recall by April 16. At that time, they'll be able to take their vehicles to a local dealer, who'll tighten the wiper arm nuts free of charge.
