Hi my 2020 Silverado Lane Assist is unavailable also. I’ve had this truck a little over a year and so far the power went out 3 times. Absolutely no power. Couldn’t even open the doors without the key. Now I keep a power pack inside the truck at all times. The dealer found nothing, after 3 days I had to take my truck home. Now the lane assist and cruise control are off and it’s 2 weeks to have a mechanic look at it. smh. I’ve been driving Chevy’s since 1976 and never had so much trouble from a new vehicle. idk
