Took my 2011 GMC Sierra Duramax into dealer for warranty work, "Poor Exhaust Fluid". Dealer loaned me a 2015 Chevy 1500 to use till my truck was fixed. Drove the loaner on the freeway at 65 MPH. Could feel the vibration at 65 and above. Mentioned it to the service writer when I took the loaner back. He said "Keep it quite as we are a where of some of these trucks vibrating". I also own a 2014 GMC Sierra 1500 All Terrain that DOES NOT VIBRATE. Lucky so far I guess. Happy New Year!!

Yes, it seems to be okay now. Your welcome. I talked to the sales person that sold me the truck, and he has one just like mine, and he knew nothing about the headlight replacement. Good communication GM!

Dealer called me today and said to bring it back. They think they have a solution but didn't get into details. I take it back next Tuesday.

I had my bulbs replaced last week and the BCM update done. I now notice that the outside temperature reading is not reading the right degrees. Over on the Duramax Forum they are saying the IPC needs a software update also. Has anyone noticed that their outside temperature is off? Mine is off by about 5 degrees and was always right on before the BCM update.
