Just received my 2019 sierra 1500 Denali ultimate back from the dealer yesterday after fixing multiple recalls. One of them being the brake assist feature and I am having the same issue as everyone else in this post. The lane keep assist is not working along with the intellibeam. I have also notice that when I go into vehicle settings on the main display under collision system settings ( something like that) all the safety settings were off... so I turned them on, exited out, went back into the settings to double check and found that it keeps defaulting to the off setting. I did this multiple times same result. Just a heads up to double check your settings because there may be more safety features not working than you may be aware of. Obviously not safe!! The worst part is everything was working great before I brought it to the dealer.
