MX_master, here are a few. I don't currently have any directly from the side or behind.

Clearly a big issue! Most dealers don't seem to have a clue about this and GM needs a service bulletin for this soon.

Here is my 2020 AT4 with a CST 4" lift, Fox Shocks, Fuel Blitz -18, Nitto 35x12.50r20. Zero rubbing and full lock with only very minor initial trimming on the front.

I have a 2020 AT4 2500 Duramax that I have had for about 6 months. This issue started around 6k miles. At first I only noticed it in the mornings when temps were below 50 degrees F. The noise is a clicking noise when you move the steering wheel left to right or just off center at slow speeds. You can even do it in park just shimmying the steering wheel. When temps are warmer the clicking isn't as noticeable. I finally took mine into the dealer yesterday and they claim "normal". Clearly not normal as it didn't do it the first 6k miles. Obviously GM doesn't know what is wrong yet, nor have a service bulletin to fix it. I also had a second clunking noise randomly occurring at cold temps as well from somewhere underneath the cab. There is a service bulletin to loosen and retorque the rear leaf springs. The dealer did do this yesterday and that does appear to help with the clunking noise but nothing yet on the steering wheel clicking noise. Love the new Duramax but coming from Tundra's I have already had more annoying issues in 8k miles than I ever did in my last two Tundra's over 10 years.
