Thanks for this info. I filed a complaint with the NTSB. My 2014 Sierra 1500 w/86kis effected by this. The local dealership (AutoNation GMC) in Lakewood, CO quoted me $2900 for this job. I'm beyond pissed. To make matters worse, my A/C went out within the last couple months and apparently that's also a common issue on this platform.
In the past month, I've replaced my rotors/pads (for the second time), I'm on my 3rd battery, and I just had to have a wheel bearing replaced. This truck is anything but professional grade.
