General Motors Co. said Thursday it has recalled 8,590 Buick and Chevrolet sedans in North America to address a potential braking problem, Reuters reported. The automaker said it recalled cars because rear brake rotors may have been installed in the front brake assembly, which could shorten the life of the front brake pad and increase the risk of a crash. However, GM expects a very small percentage of the recalled vehicles will contain the front brake assembly misbuild.
