Engine Monitoring Technology

In an effort to continually improve our product, 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. The technology will be installed free of charge on 2011-19 Sonata, 2013-18 Santa Fe Sport, 2019 Santa Fe, 2014-15 & 18-19 Tucson, and 2019 Veloster N vehicles through a free software update performed by any Hyundai dealer.

Additional information can be found in the FAQ section.
