Most days when I'm using cruise control with lane centering enabled it's problem free and I just have to remind it my hands are on the wheel with a little tug on the wheel here and there.
A couple times now the entire trip is plagued by the truck steering over the line on both the left and right side every minute or two and then giving the over the line warning. On these trips I'll also occasionally get the yellow "Cancelled" warning when I haven't hit cancel or the brakes or a red warning that looks more serious but has no text on it.
Does this sound like something I need to wait on a software update or is it a dealer issue where something is out of alignment or calibration?
I believe there is a setting for the strength of the lane centering.
My dealer was walking me through the settings when I first bought mine. We set it to high. High is overpowering and actively fights against you, but it is accurate if you give it the reigns.
It is sometimes sketchy on sharper turns on the highway when 80mph+. If I know the corner is rather sharp, I will cancel and do the turn my self.
Default was for sure not high - i don't remember if low or medium. Either way, it was not high. Change it and keep the strength of the lane keeping system on High.
