2017 sierra denali/ oil leak

Question

Any issues with rear main seal leaks on these motors 6.2, under 4k miles. Also when you do oil change/ free oil change for new vehicles thru dealership do they use synthetic oil?

What does happen allot is the grease monkey that didn't finish sixth grade and paid minimum wage spills oil all over the cross member and lower shield making it look like there is a hole in the pan. :thumbs:

Any advice on a sweating rear main, oil drops on small access plug by front of tranny. Not bad but not acceptable from a 55k truck with only 4k mile on it. Also running board motor leaking hydraulic fluid any news on that?

Go to dealership. Warranty.

Wouldn't change the oil until you have the dealer look at the leak.  Let them handle the oil change under warranty if the pan needs to dropped.  The leak could also be the pan gasket at the rear.
