As being a GM truck person all the major part of my life I have never been so disappointed in my 2019 Chevrolet 1500 RST . As a former fleet/truck manager I should have known not to purchase the first year . Month old starter would not shut off . Fixed not sure what was done . Number two check engine light came on On Star told me I had 7 days to take to dealer or the truck would not start. Brake reprogram. And today the lovely 8 speed missed a shift and set a code not fixed. GM knows the lovely 8 transmission is troubled but they will not pay to have the transmission fluid to be changed to help correct a problem that they curated. Time of a change???
