Audi is recalling about 1.2 million cars and SUVs worldwide because the electric coolant pumps can overheat and possibly cause a fire. The recall covers the 2013 to 2016 A4, the 2013 to 2017 A5, the 2012 to 2015 A6, and the Q5 SUV from 2013 to 2017. All have 2-Liter turbocharged engines. The Volkswagen luxury brand says in U.S. government documents that the pumps can become blocked with cooling system debris, or moisture in the pump can cause an electrical short. An Audi spokesman in the U.S. said there have been reports of fires but he had no details.
