There are different ways to reset the check engine light on the 2018 Hyundai Sonata but sometimes it will just go off by itseLFAfter driving for a while. Another way that You can reset the check engine light on the vehicle is to unplug the battery, wait for about 20 minutes and then plug it back in. If neither of those work then You will have to use an electronic scan tool to find the problem and fix the issue. One of the common problems why the light might be on is because of a loose gas cap, You can see if that is the problem without using a scanner. If that is not the problem then You need to use the scanner, find the problem, fix it and then reset it through the scanner.
