US auto giant, General Motors will recall more than 2 million vehicles produced through a joint venture in China. The venture between GM and Shanghai-based SAIC will recall 2.16 million Buick and Chevrolet branded vehicles because their engine valves could corrode after extended use, the company said. The recall affects some Buicks produced between 2009 and 2015 and Chevrolet cars made between 2009 and 2016.
