2019 GMC sierra with 56k miles when accelerating transmission seems to get stuck in first gear makes idol sounds rpms jump up then hard shift into second, makes the truck jerk when it happens, since the issue started it happens every time I drive it. I took it to local GMC dealership on 2/9/21 manager said �yes it's a known issue with GMC & that year model trucks� 2 days later called to see status of truck manger said his transmission guy found the issue and fixed it said computer and transmission not talking to each other did a �transmission relearn� was covered under power train warranty. I had the truck back less than 24 hours and now back to having the same issues again! clearly it's not fixed and concerning this is going to be a safety issue while driving! GMC �known� issue then issue a recall and fix it right the first time!.
