China's quality watchdog said Friday that Chongqing Chang'an Suzuki Automobile Co., a sino-Japanese joint venture, would recall 10,326 Alto vehicles due to gas filter problems on the Chinese mainland as of Feb. 5. Oil leaks may occur due to gas filter faults caused by improper manufacturing techniques, and will post potential safety risks, the General Administration of Quality Supervision, Inspection and Quarantine (GAQSIQ) said in a statement on its website. The recall involved Alto models produced from July. 6, 2009, to Jan. 17 this year, and the manufacturer would fix the problems for free, said the statement. Owners can contact Chongqing Chang'an Suzuki Automobile by phone on 400-1077988 or contact the GAQSIQ on 010-65537365.
