The last week of 2022, I bought a new Sierra 1500 Denali, 6.2L V8 engine. Salesperson showed me all functions, including setting up the gap for the adaptive cruise control. The adaptive cruise control would never work. I just returned from the dealership: "Oh, it was not installed, that is part of the high end package. So...all talk about high end Sierra trucks, such as the Denali, having "adaptive" cruise control: No, not correct. There is only old-fashioned cruise control. The feature to set up up the gap in 1-2-3 increments means NOTHING. $72,000 for old fashioned cruise control....what is wrong with GM ?
