"The department investigates evidence of safety defects and non-compliances with Australian Design Rules and provides advice to the Australian Competition and Consumer Commission on automotive product recalls," the statement said. The ACCC is yet to issue a recall. A statement from Hyundai says: "Hyundai Motor Company of Australia is in touch with the vehicle safety standards division of the Department of Infrastructure and Transport regarding the electrical switch issue. Hyundai will co-operate fully with the department in assisting with their enquiry." Hyundai says the fault is not a safety issue because the brakes still work. Hyundai has so far refused to reveal how many cars may be affected, but it sold more than 70,000 vehicles between August 2011 and May 2012. The company told News Limited only four models were fitted with the faulty part but the dealer bulletin says it relates to "all" models.
