Just got my 2019 Silverado ltz out of the dealership after having 5 recalls addressed, oil change and tire rotation. My lane assist switch will not work. No DIC warning but the system is definitely inoperable. The service manager is test driving it right now. He is telling me it has to recalibrate after every oil change. I have had 2 previous oil changes and nothing needed to be recalibrated. We'll see when he returns.
