GM ordered a windshield wiper recall that was limited to Canada's "corrosion provinces" back in June. Well, turns out we use plenty of road salt here in the US of A as well, so the recall is expanding.
"The first trouble reports came from Canada in December 2015 when SUV owners were complaining about failing windshield wipers during the winter. Dealers said the reported failures involved the windshield wiper’s ball joints coming loose from corrosion and separating while the wipers were activated."
No recall date has been set and GM isn't exactly sure what they're going to do yet. All they know is the 2013 Chevy Equinox and GMC Terrain need to be repaired.
