General Motors' joint venture in China, Shanghai GM, will recall over 3.3m Buick, Chevrolet and Cadillac vehicles from 20 October because of a defect with the suspension system, Reuters quoted China's market regulator as saying on Saturday.

The recall includes cars produced between 2013 and 2018, the State Administration for Market Regulation said in a statement cited by the news agency.

GM will contact those affected and repair the vehicles free of charge, it said.

GM Shanghai told Reuters by text message the suspension arm may be deformed under extreme operating conditions but there are no known casualties related to the issue.
