Industry analysts said the recall was significant because of the sheer number of Buick and Chevrolet cars involved, but GM's reputation in the country was relatively safe, as there were no casualties associated with the problem, the Wall Street Journal reported.
The issue may impact sales. GM and SAIC in the first 11 months of 2013 sold 2.89 million vehicles in the country, second to Volkswagen, which has sold 2.96 million.
About 30 percent of GM's sales were in China January through November, making it a critical market for the company, which represents the world's largest automobile market with more than 16 million sold through November.
The China Association of Automobile Manufacturers said 16.2 million vehicles were sold in China through November.
The fuel pump brackets will be replaced for free, a service that normally costs about $80, the Journal said.
The recall involves 1.2 million Buick Excelles produced from 2006 to 2011 and 243,297 Chevrolet New Sails produced from 2009 to 2011.
China's General Administration of Quality Supervision, Inspection and Quarantine also announced a recall of more than 80,000 Kuga kugasport-utility vehicles produced by Ford and its partner, Chongqing Changan Automobile Co.
The Ford recall was due to substandard steering knuckles, the Journal said.
