All,
I have a 2020 Silverado 3500 High Country.
I was recently towing my 5th wheel, and the dashboard flashed a message "Tailgate Open" and chimed 4 times. It wasnt open. I hit the "OK" button and it went away. Over the course of a 100 mile trip, it must have went off at least 100 times. I navigated the menus and couldnt find a way to disable this warning message.
When closed, there is a decent amount of play in the tailgate. I used a T40 torx bit and tried adjusting the knobs that the tailgate latches onto to see if that would help. We just went on another 100+ mile trip and the same thing happened. So that didnt help.
It only seems to happen at highway speeds. And not only when hitting a bump - the road can be perfectly smooth and it will still go off. And it also seems to only happen when I am towing (I have hit the interstate for 25-30 miles at a time without towing and never had it go off).
Anyone had this issue? I am going to schedule a dealership appointment, but based on the circumstances, I suspect it is going to be a difficult one to diagnose.
Thanks in advance!
