2015 GMC Sierra cold start issue

I just purchased a 2015 Sierra. But I’ve noticed that after it sits for a while, especially overnight, when I try to start it, it has to crank several times to fire off. The dealership says nothing is wrong with it. Thoughts?

It's much colder where I live and with the DI trucks mine cranks for several seconds when it's really cold. When it was -15 to -20 it was probably 5 seconds at least before it started.
