Does the 2010 2500 HD stability control have HILL-HOLD function? This type function seemed to work when new, but now will not hold.

GM dealer maintenance shop states its NOT part of my stability control system. Yet I read threads there was a software problem, but no model years were listed.

I pull a 30 ft 5th wheel and miss this function if it existed.

I think you were misinformed Don....read away!

GM discovers flaw with HD pickup hill-hold assist, fast-tracks fix

Yes, Mike I have seen this before. But the testing date was July 10, 2010. So this would most likely be for the 2011 model year. Where is the cut-off date for having the hill-hold function?

I don't know when the cutoff date would be.

I wonder how much luck you would have if you went to another dealer and asked them about it. It seems its just a software update.
