Took my 2019 Sierra Denali in for an oil change and tire rotation. They told me there were several service bulletins including a software update. I started complaining after 3 1/2 hours as they said it would take about 1 1/2 hours. Finally got the truck back with not explanation of why it took so long. Now the lane assist and forward collision alert doesn't work when there were no problems prior to me taking it in for service. This is the first bad experience I have had with this dealer.
