As many as 3.2 million vehicles were recalled in 2012 for being faulty, up 75 percent from a year earlier, the country's top quality supervisor said Monday.

The General Administration of Quality Supervision, Inspection and Quarantine received 9,640 vehicle complaints last year, up 9 percent from 2011, said Fu Wenbiao, a deputy director-general with the administration.

China set up a recall system for faulty cars in 2004.

Vehicle manufacturers and dealers could face tougher financial penalties if they violate newly amended automotive recall rules, which took effect on Jan. 1.

Industry insiders said the new rules will help raise the standards of vehicle safety and the after sales service for all cars, including imported ones.
