I have a 22 at4 with about 15,000 miles now and for two weeks now my adaptive cruise control and lane assist among a few other features have completely quit working. I figured I’d give it a bit of time to cycle but nothing has changed. All sensors are intact and I see no issues. Taking it to dealership Friday and will update if I actually get an answer. New to the thread but I put on about 1000 miles or more a week for work so I’ll definitely be testing the longevity of the truck as the miles rack up sooner than most others.
