Dealer technician said that he couldn’t find any additional sound . He compared with other similar hummer EV and sound is same.

What's the current status?

 

[jay42]

dealer recognized the sound but says it’s by design of vehicle as others have it too .
Only GMC can help further .

We need more people to reach out to GMC .
I think they can’t improve the same without aerodynamics change in front .
