i have the same noise on my 2019 Silverado (only 9500 miles) but mine's not during cold start. I hear it after driving about 20 miles at freeway speeds, not heard during in-town driving. To me more like a wheel bearing. Doesn't do it at any time when stopped or going less than 20 MPH. Was told today from dealer that engineers can't replicate noise and are trying to figure it out.
