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 .

 

[jay42]

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

That's correct.

Is it a tire noise ? My noise is manageable until you get above 60 . Pretty sure it’s coming from the tread design on the tires. Thinking about going to a more street designed tire .

When you buy a basically convertible with sky panels, wind noise is "assumed risk". That said it's like living next to a rail road - you stop hearing it after a couple of weeks.

I get the buzzing noise too. It just started and I think its the passenger windshield wiper vibrating. I asked a person who had one and he said he took it to the dealership and they adjusted the wiper. Hope so. Its annoying.
