I have a 2021 Silverado High Country. Great truck. But the ACC has tweaked on me as well but only when going uphill. It's as if the computer is interpreting the road as captured by the camera as a collision threat and then braked very hard causing me to have to turn the cruise off as quickly as possible to regain speed and actually avoid someone from colliding with me from behind! Then...the ACC won't rearm for several minutes thereafter for some reason. It's frustrating since I do like the feature even though I don't rely on it to text or otherwise not stay alert. There are too many "non-alert" drivers out there already to do that! It doesn't sound like there is a universal diagnosis of the problem or fix either. Someone mentioned using cruise control without ACC. I guess I didn't realize that was possible on a vehicle equipped with ACC. How exactly is that done? Thanks!
