Its completely normal everyone. Some do it, some don't. My 2015 has been doing it since new and it is now tuned. Runs better than new.
I have a fleet of these Tahoe/Sub 5.3's at work and it is hit or miss with the ticking. We run the dog **** out of these things and they do not skip a beat.
I would replace the battery and the ground cable that is on the battery. Known issues with the ground cable internally going bad. Batteries can do weird things to electronics, even if they show a good charge.

I just replaced my postive battery cable. I had problems with slow starts/intermittent electrical problems. The nail in the coffin was when I put it in park and it would die as if someone unplugged it. It is a cheap part and you can try yourself without dealing with the dealer. Give that a try...
