    I have a 2021-Silverado High Country with 3.0 Duramax with 42k miles. I am having the same issue described above. This is the second time this has happened. The first time, about 6 months ago the whistling sound finally went away after a full new tank of fuel. Not sure what is causing the whistling noise during acceleration.
