Hyundai - Knock Sensor Detection System - How It Works

In an effort to continually improve their product and as prompted in part by the recalls, Hyundai has developed new engine monitoring technology called a “knock sensor detection system.” The technology enables the detection of potential early engine issues caused by excessive bearing wear, and has been evaluated by one of the world’s leading engineering and scientific consulting firms. Customers are being notified through multiple points of contact. The technology is being installed on model year 2011-18 Sonatas, 2013-18 Santa Fe Sports, and certain 2014-15 and 2018 Tucsons through a free software update performed by any Hyundai dealer.
