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 is being installed on certain model year 2011-19 Sonatas, 2010-2012 Santa Fes, 2013-18 Santa Fe Sports and 2019 Santa Fes, 2010-2021 Tucsons, 2012-2017 and 2019 Velosters, 2011-2015 Sonata Hybrids and 2016-2019 Sonata Hybrid/Plug-In Hybrids, 2014-2016 Elantras and 2014 Elantra Coupes and 2014-2020 Elantra GTs through a free software update performed by any Hyundai dealer.
