Shanghai GM, a joint venture with General Motors, is recalling 7,056 Buick cars in China due to front brake problems, China's top quality watchdog said.

Involved are some of the Buick LaCrosse sedans made between March 10, 2006 and March 22, 2007.

"The problem may cause vehicle vibrations in a minority of cases, affecting manipulation and comfort," the General Administration of Quality Supervision, Inspection and Quarantine said.

Shanghai GM will contact the buyers and repair the problematic parts free of charge.

Shanghai GM, the Detroit-based automaker's venture with Shanghai Automotive Industry Corp., China's biggest carmakers, also produces the Cadillac and Chevrolet cars.

The joint venture was China's No. 1 passenger vehicle producers last year, with sales of 413,400.
