24 Tahoe RST 5.3 cold start noise

[DwDrummer]

Just bought a brand new RST about 5 weeks ago and noticed on a cold start it has this ticking sound, it will go away once warm but was wondering if this is normal or do I need to take the truck to the dealer? The truck only has 395 miles hoping they don't have to tear into it this soon

Thanks,
DW
