According to this article from Automotive News, GM will no longer use the “GM Goodwrench” or “Mr. Goodwrench” brands when referring to dealership service and maintenance beginning next year. Instead, each of GM’s four remaining brands (Chevrolet, Buick, Cadillac and GMC) will have its own “Certified Service” (i.e. “Chevrolet Certified Service”).
The article does note that GM will continue to use the Goodwrench brand in Canada, where it has more cachet.
