2020 GMC Sierra AT4 5.3L 2.7k miles squeaking behind steering wheel

[Endshine]

There’s a squeaking coming from behind or under the steering wheel at 20mph 2000 rpm and 40mph 2500 rpm. It sounds like plastic rubbing checked for any trim that would be lose and nothing. Any ideas? I can upload a small clip and try to record more if needed. Thanks

Here's the sound I'll get a better video after work. No turning involved btw

That sounds similar to an intermittent squeak our '21 Silverado gets (but hasn't done lately). It's usually attributed to driving over bumps at lower speeds. It's most likely a wiring harness shifting around a bit and I've read of others that had the dealer reroute or zip tie a transmission wiring harness that's on top of the bell housing to resolve it. On ours, I noticed it diminished after I re-clipped a heater hose the dealer did not re-secure after we had our lifters replaced, but it's possible that they are unrelated.

 

If there are any exposed T15 torx or 7mm bolts that secure any trim in the area, I'd check to see how tight they are to rule out one possibility, but sometimes a loose fastener may be hiding deeper behind another trim panel. I also lubed up all of the weather stripping on ours with silicone spray and put a tiny amount in the cracks where more flexible trim panels meet as another troubleshooting measure, but once again, I'm not certain it really made any difference in our case.

Not sure if this applies, but on my previous ‘14 there were four torx bolts that were loose behind the panel below the steering wheel.
