My truck is a 2016 Sierra SLT 2wd. The drivetrain has " hopped" or "lunged" between gears since the first week I had it. I have reported it at every service to Williams Buick GMC in Charlotte, NC. I really am concerned as I pulled off the interstate into a rest area, as I parked the truck lunged so hard that it jumped onto the sidewalk. Had someone been there, they could have been killed.
I have spoken to several Sierra owners with the 8 speed transmission. This is an issue with a majority.
GMC needs to fix this before someone is hurt and/or killed.
