General Motors shakes up management, names new chief of quality

General Motors has promoted its purchasing chief to be its head of quality as part of a management shakeup.

The move comes after all GM brands but Buick performed worse than average in this year's Consumer Reports auto reliability survey.

Quality and customer experience head Alicia Boler-Davis will remain a senior vice president, but will no longer lead quality.  She's now in charge of a department that handles GM's interactions with its customers.

Purchasing head Grace Lieblein takes over as vice president of global quality.

Both executives report to CEO Mary Barra.

Cadillac, GMC and Chevrolet all scored below average in the Consumer Reports survey revealed last month. GMC fell 10 places largely due to problems with the new Sierra pickup. Buick was the top brand from a U.S.-based automaker.
