I have have had my OT since 11/2024. Aside from the cabin noise that everyone (Myself included) has been complaining about, I have a new noise to add to my OT symphony. About a week ago I started to hear a hum and vibration noise coming from somewhere. This would happen between 28-35mph. Best way to discribe it is like a loud pager on vibrate if you are old enough to know what a pager sounds like. Here is what I found.. I got up on a ladder and tapped down with the palm of my hand on each crossbar, they all were solid except the third one from the front which slightly vibrated each time I would bang it with my palm. I used a couple of cable ties to run a test and the noise was gone, came back as soon as I removed the cable ties.. I will share my results with service so they can fix or replace. I hope this info helps!
