Hill start assist holds the brakes for a couple of seconds after taking your foot off the brake pedal ,or until you touch the throttle, whichever comes first, on a steep incline, then eases off the brakes gradually.
If you are not aware of the system you can be too quick to let go of the clutch and may stall the engine.
I have done it myself. (I have a manual transmission).
Maybe hill start assist is stalling the engine?
I have the same clacking noise from the cardan shaft. I think it is coming from inside the transfer case, where there is gear lash between the gear in the transfer case an the gear seen on the pictures. Dont know if it is excessive or normal.

Yes. As far as I can see, the leading edge is the most important one.

I have the blower motor chirp problem too. Found this on another forum. Will probably try it out later on.

The reason for the squeak is the brushes that ride on the motor
shaft, that is why it ticks every revolution and the fast it turns the
faster it ticks. if you remove the fan and then take off the metal back
cover of the motor it will expose the brushes (carbon pieces with the
springs behind them that are wired to where the electrical connection
plugs in.)
The reason that all the previous suggestions work for a while and
then come back is because you end up adjusting the bushes slightly so
that they dont make noise but eventually it wears back in and ticks
again. The same thing happens when you get the blower replaced under
warranty. It will be quiet until the brushes wear in all the way around
the motor shaft and the edges start to catch, making the ticking
sound.
To fix this, remove the brushes from the motor and use a file to file
off the leading edges of the brushes to a 45 degree angle. the brushes
are very soft and this is ease to do. reinstall and put back into
service and you will have silence finally.
I almost sold the truck I was so annoyed with this but silence is
golden. I actually had to hit the switch the other day to see if the fan
was on because i was just so used to hearing it all the time.
good luck and there are pictures of the brushes in the first post on this forum which show them very well.
Hey guys, 3 months now and all still quiet. This is with the fan running every day.
To get rid of the noise i filed the leading edge of the brushes and i
didnt write it in the first mail but i actually filed the back edge
also. I would say that i filed it to a 45 deg angle about 1/8" to 3/16"
down and then also streached the springs about an extra 1/4" to put a
little more force on the brushes.

Es muss reparierbar sein.

Excuse me for writing this in english. Run it through a translation site if you like.
It seems like GM has changed the dafault manual gearbox fluid being used in all of their vehicles from BOT 0402 to BOT 303 (around year 2012). The new fluid has a viscosity rating that is half the thickness of the old.
(BOT 0402 Viscosity @ 40°C : 75.6 / BOT 303 Viscosity @ 40°C : 31) I suppose this has to do with fuel efficency. I don't know if this is the case, but could the gearboxes be more "clunky" due to the fluid viscosity being lower?
