I love my 2020 Sierra Denali 1500 but one annoying problem. The power running boards do not always work. Sometimes they come out/sometimes they don't. Once out, sometimes they go in/sometimes they don't. When one side messes up usually the other side does too. The dealer cleaned the linkage but still they don't always work. It only has 5,000 miles so they cant be worn out. Has anyone else seen this issue?

thanks tmo! I did not realize that. Maybe I need to dig into the manual a bit more. I have done some more research, watching a lot of YouTube and it appears the marketing material for the safety systems is better than the system. So I wonder if the pedestrian detection system works? Bottom line is I love the truck but a little dissatisfied with the safety technology.

I bought a 2020 Sierra 1500 Denali 5 days ago and can't seem to get the lane change/lane departure function to work. I also noticed my forward collision warning is not working. For the lane change I have the white icon on the info center and the two white lines in my HUD when I turn lane departure button on. When driving at a constant speed on a lined road i see the HUD constantly change between white and green lines but not red when i slowly swerve over the line. I know my other car's lane warning works on these roads. For the forward collision alert I noticed when backing up and moving forward that I was not getting forward collision warnings. Rear beeps were loud and clear but nothing on the front until I was literally inches from an object. I set up a 3' X 5' piece of cardboard and drove down the driveway at about 15 MPH and had to apply brakes because there was no warning. As I inched up to the cardboard it sounded when I was less than a foot from hitting it. I have read the manual and gone over every setting I could find but nothing seems to help. I would just go to the dealer but I'm on vacation about 3 hours away so I thought I would reach out to the community and see if someone has a solution.
