Hello, have a 2018 Chevy Tahoe LT, 5.3l with 56k on it. 22" wheels 4x4. Have been chasing a interior noise/ drone. From 37mph and up while in driver seat it sounds like a window is open with the ear pulsating noise. Did it with old tires and new tires. Recent shocks, and brakes. Tried different wheel set ups. Sometimes it's not there when cold, after driving then sitting for some time it gets loud and worse. Any suggestions?
I would inspect underneath for anything unusual. Loose parts, exhaust, driveline etc.
But isn't your car still covered by warranty?
Thanks for the advice I have been looking at everything. Unfortunately it's not under warranty.

Typical powertrain warranties last for 5 years or 60,000 miles
@mountainmanjoe You're right course it just ran out in April 🙁
aw shucks. It's disappointing to have a noise with only 50k. But maybe it's something very minor.
Give a it a thorough inspection. Could just be a loose exhaust heat shield or something.
