GMGeneral Motors will phase out its Goodwrench maintenance brand in the United States as it seeks to focus marketing efforts on four key brands.

Goodwrench, used by GM dealers to advertise maintenance and repairs for more than 30 years, will be replaced with brand-specific labels such as Chevrolet Certified Service and Buick Certified Service, The Detroit News said.

"Our No. 1 priority is providing a world-class ownership experience that creates positive long-lasting relationships with our customers," said Steve Hill, GM's vice president for customer care and after sales.

Goodwrench will officially die on Feb. 1 of next year.

Goodwrench was created in the mid-1970s to promote GM's parts and service dealerships. The brand was a major sponsor of NASCAR racing.
