Why's my 2016 Hyundai Sonata touch screen not working?

If the touch screen is not working in Your 2016 Hyundai Sonata the first thing that You should do is reset the screen by holding down the power button until it reboots. Usually this fixes most of the problems with it. You should also check the software version that You are running in Your car. There are software updates available for the touch screen that improve the reliability and remove bugs that can cause it to freeze up and not work. If Your screen will not turn on at all then the first thing that You should check are the fuses to it to make sure that they are in tact and free from any damage that would prevent it from working.
