2016 sierra 1500. Ac leaks, transmission went out (transfer case exploded), head light problems,fog lights suddenly stay on all the time, violent shaking (death rattle) when up in speed changed 3 sets of tires new suspension lift kit nothing helps that, transmission clunked when shifting from part to reverse, brakes had to stand up on at times to stop, it will shut off on you all of sudden too or every dial and control goes crazy you slow down not by choice then it corrects itself in a few. It happens more than you like.
