2015 Silverado has developed a rough idle while in drive. When truck is stopped but in Drive there is a noticeable engine vibration at idle. Almost like the idle is too low. There is actually a GM service bulletin, PIP5211E, about the issue. I have taken to my local dealer and they cannot find anything and don't see any trouble codes. They didn't know about the service bulletin. Now I need to waste my time trying to get this resolved for a 2 year old $50K truck.
