General Motors is to phase out its Goodwrench brand name from 1 February next year and will provide its Chevrolet, Buick, GMC and Cadillac customers with their own Certified Service brands.

Chevrolet Certified Service, Buick Certified Service, GMC Certified Service and Cadillac Certified Service are being launched as part of a larger strategy by the company to strengthen the relationship between the customer and the four brands.

"Our number one priority is providing an ownership experience that creates long-lasting relationships with our customers," said GM vice president and general manager, customer care and aftersales, Steve Hill.

"Certified Service supports GM's strategy to focus on the four  brands - Chevrolet, Buick, GMC and Cadillac - and is an extension of the customer's vehicle purchase experience at the dealership.

"This is more than a name change - it is a declaration of our commitment to our customers, with exclusive vehicle diagnostics and connectivity via OnStar, competitively priced services and parts, increased  advisor and technician training and working jointly with our dealers to focus on customer satisfaction."

As an extension of this strategy, GM will phase out the Goodwrench brand name effective 1 February.
