Engine Monitoring Technology And Extended Warranty

In an effort to continually improve our 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 certain model year 2011-19 Sonatas, 2013-18 Santa Fe Sports, 2012 and 2019 Santa Fes, 2014-15 and 2018-19 Tucsons, 2015-2016 and 2019 Velosters, and 2011-2013 and 2016-2017 Sonata Hybrids through a free software update performed by any Hyundai dealer.

Knock Sensor Detection System: How It Works

Hyundai has extended the warranty of these vehicles for both original and subsequent owners for certain engine repairs. If your vehicle experiences an engine issue, please contact the nearest Hyundai dealer for evaluation and determination of warranty coverage or visit Hyundai’s online Customer Assistance Center at
