I have a 2019 Z71 and has had a hard shifting issue within a month of purchase. Sometimes it does it to 4th gear. every time i bring it up to the service department they say GM know about it and it is normal. This is the first GM truck I have had since 1998 and never had this many issues with any Ford. I am tempted to get in on the lemon law suit that is going on with GM.
