thats not even close to part of PDI.
PDI = pull the plastic wrap and cardboard out of the interior, remove paint guard film, drive it around the block to make sure the wheels don't fall off. most dealers don't even set the tire pressure during PDI.

I was being tongue in cheek implying they get paid for it but don't go through the trouble of checking. ;-)

To a big part of this but then again I would say also it is alot up to the dealership & really getting the tech guys to do what need to be done on every new car that comes into the dealership.

This generally applied to the first batch of deliveries in 2013, including my own.
The bulletin was actually upgraded to a recall in early 2014, and you will be able to see if your vehicle was affected by this by visiting https://recalls.gm.com/ and typing in your VIN.

I bought a new silverado in 05, with any new vehicle I check the fluids the rear was down 1 quart.
A year or so later I was checking out the ODI page about my vehicles, I do this for recalls and TSB's.
There it was a TSB on my truck stating that trucks were experiencing pinion bearing failures due to not enough fluid being put in at the build.

My 2014, delivered in April 2014, was low a little over half a quart...
I checked, added fluid, and have not had any problems.
It was about 1/2 inch below the fill hole, so not low enough to cause damage.
I think I read where the differentials are filled by manufacturer when they are assembled, so they are probably never checked after that.

As a chevy dealer svc mgr, I was responsible for my tech's shortcuts. If a new car came into the shop with a problem that was pure and simple neglect on the tech's part, the tech ended up pushing his/her tool box out the door.

The best way to check if the rear is full is to run the car, get the rear up to operating temperature.
Then check the fluid, you might find when you open the plug some fluid will flow out, if it was my car I would let that little bit out.
It's OK to be 1/2" or so low cold, the fluid expands when hot.
We do need to be careful because most of us only jack up one end of the car, the incline can make the fluid appear low, when it would be at the correct level on a level surface.
