I own a 2019 Colorado Z71 4x4 (3.8L v6 gas). I did have the well known and documented transmission shudder, but it was resolved with a transmission flush and fill. The only other issues I've had with my truck are lights burning out, but after 60K miles, they start to do that. Maybe I was blessed with one of the very few good ones?
