Had posted this a few days ago. I have '23 tahoe z71 and noticed when driving at 60 mph or faster I get a whistle-like creaking noise coming from the driver side door. I took to my local chevy dealer and the service department saw there is a 'bulletin' from GM for similar trucks from 2020-2023 where customers are complaining about the same noise. The bulletin called for tightening the body harness pass-through and/or tighten the I/P tie bar bolts. No clue what this means but after the work was completed, the noise is still there! Lol, anyone know anything about this?
