Hyundai Canada will recall 255,370 cars and sport utility vehicles to perform an update to the engine control unit (ECU) to detect potential problems before the engine fails. The models that need update engine software are the 2013-2018 Santa Fe Sport, 2014-2015 Tucson SUVs and the 2011-2018 Sonata sedan.
