2021 Suburban RST Diesel
The vehicle makes a rubbing noise when turning the wheel. The tires are not rubbing. The dealership has stated that the power steering lines are getting pressed, and GM has no fix. Also, ball joints are rubbing but waiting for new ones to be invented out of a different type of metal. Anyone with this same issue?

I am taking mine to the dealership tomorrow for this same thing! So TBD

Anna - was the dealership helpful? Mine wasn't. Claimed they couldn't hear the sound/get it to replicate. Mine is most obvious when the truck is cold in the morning. After driving a while the issue goes away. Frustrating and makes me concerned for possible long term issues.

Having a similar problem with mine. Especially when it's cold out, but eventually goes away when the vehicle warms up.

Reminds me of a past problem with some earlier GM products and was called "Morning sickness" , solution was to replace the steering rack assy.

Any solutions yet to this issue? I have the same problem.

I have had mine back twice now. Next step they say is to replace the rear differential. Unfortunately they say they are on back order and have no idea when they will get one. Mine also used to be worse in the morning and when cold but after 3 months it does it all of the time. I have contacted GM directly and they did nothing.
