General Motors is recalling certain model year 2011 Chevrolet Colorado and GMC canyon vehicles manufactured from September 22, 2010, through November 5, 2010. Some of these vehicles have the condition in which the windshield wiper motor crank arm nut may not be tightened to specification. When the wipers are operated with a build-up of snow or ice, or if the wipers are operated on a dry windshield, the nut could loosen. If there is sufficient loosening of the nut, the wipers could become inoperative.
Dealers will secure the wiper motor crank arm nut free of charge. The safety recall is expected to begin on or before May 11, 2011. Owners may contact Chevrolet at 1-800-630-2438, GMC at 1-866-996-9463 or www.gmownercenter.com.
