I have a 2010 3500HD with the 6.0 liter. I bought this used with 12,000 miles and am having a problem GM says is normal and there is no fix. On a cold (60 degrees - summer) start, when starting to accelerate the motor hesitates and runs rough for about the first 1/4 mile and then everything is normal. I've had it to the GM Dealership 2 times and they can not find a code or anything. The last time the mechanic did some research and found a bulletin wherein it talks about this problem with the 2009-2011 Silverados, Express vans, GMC Sierra.
The bulletin says this is normal and the fix is tow warm the motor up for at least 2 minutes. No other fix advised.
Wow, for the money they get for these rigs, this is not an acceptable answer if you ask me.
Does anyone else with the 2009-2011 6.0 liter have this problem, I can't find any info while searching the internet.
