The agency said Friday the recall affects 1.2 million Buick Excelles made from 2006 through part of 2012 and 250,000 Chevrolet Sails produced between April 2009 and October 2011 and some made last year.
The bracket to be replaced might crack and in extreme cases cause a fuel leak, the Administration for Quality Supervision, Inspection and Quarantine said in a statement.
The recall is GM's second this year in China. In May, the government announced a recall of 2,653 imported Cadillac SRX sport utility vehicles to adjust nuts on wheels that said might loosen due to torque.
