Hyundai and Kia are recalling 1.4 million vehicles due to a safety issues presented by faulty engines.
The Korean automakers said in a document posted Friday by the U.S. National Highway Traffic Safety Administration that debris from manufacturing can restrict oil flow to connecting rod bearings, which can increase temperatures and cause bearings to wear and fail. This can cause the engines to stall, thus increasing the risk of a crash.
Hyundai spokesman Jim Trainor said that owners of these vehicles will hear a knocking sound from the engine that will become more frequent as the engine speed rises, adding that engine warning lights may appear on their dashboards. He noted that the company has yet to receive reports of any crashes or injuries related to the problem.
The recall covers vehicles in the U.S., Canada and South Korea and includes the 2013 and 2014 Hyundai Santa Fe Sport and Sonata, the 2011-2014 Kai Optima, the 2011-2013 Kai Sportage, and the 2012-2014 Kai Sorento.
SUVs covered in the recall have either 2-liter or 2.4-liter gasoline engines, the U.S. versions of which were made at Hyundai’s engine plant in Alabama.
Hyundai and Kia will begin the recall on May 19, and the companies will contact owners and have dealers inspect their vehicles.
