Sonata I45 (LF 2015+) :: 2016 SE - Horn Does Not Chirp Upon Locking

I just purchased a used 2016 Hyundai Sonata SE. Inspected the car from top to bottom upon purchasing but failed to check one thing. I have discovered the horn does not chirp upon locking (pressing fob lock button twice). The system panel shows the car has this feature and the box is checked to do so. The doors do lock and the lights do blink. The panic button when pressed on the fob also makes no sound. Again, the lights blink on the car itself when the panic button is pressed. I have researched and have came up empty.

I can not seem to locate the hood switch or sensor on the car where older models seem to be. Dealer says it is in the latch on 2016's but I am uncertain this is correct as I called several dealers and got different answers each time. They all want me to bring the vehicle in but run the risk it is not covered under warranty depending on the issue. Car has 39K miles. Horn works fine. Carfax was clean so supposedly accident free. I'm focused on the hood switch because most of my research pointed in this direction.
