I am hearing a humming noise that seems to be coming from the right rear.
At first I thought it was just road noise, but it is not.
Anyone else have or heard this?
Taking car to dealer tomorrow and hope they can find and correct this.
2019 Envision P2 with 26000 miles.
Thanks for any assistance.

Could be a failing wheel bearing.

Thanks for the info.
I will be sure to ask them to check that out.

Well all turned out ok. The front clunking was caused by a loose facia bolt!
And the rea humming was resonance from the exhaust. Tail pipe was moved a bit and all good now.
I know that this is a weird outcome ,but problem solved.

However when I got home I discovered the look of the gauge cluster had changed.
Brighter on the oil temp side than the tach side. And brighter on the amps side than the fuel and temp side.
Almost like the the whole assembly had become smaller.
Call into the dealer today.
Has anyone else ever see this?

Glad they fixed your humming....not sure what to make of the gauge cluster issue.

The local Buick Service manager called and told me to bring in on Wednesday.
My son is the service manager for a Buck/GMC dealer in the Minneapolis area. I don't live their so not my dealer.
He had never seen or heard this happening either.
He will check with his techs and GM spec sheets about this.
I bet it is something as simple as disconnecting the negative battery cable!
More to come.

Well today the techs checked everything they could think of.
Ran computer scan, called GM tech support.
Results all agreed that this is something that changed on the newer models and was somehow changed on existing models also.
I had an idea that since there was only one new Buick in the showroom that we should check it's display out.
The SUV was a 2022 Enclave Avenair. The service manager and I checked out the display and it looked the same as mine.
The consensus was that somehow a change was flashed to existing units.
Methinks we will never know.
An interesting sidelight to all this was that they offered me $2,500.00 more that I paid for my car in 2021. It is a 2019 model.
But there is nothing to buy.

Interesting... My 2018 Envision has developed a subtle clunking in the suspension, I think from the front passenger side. I took it in about 6 months ago and they couldn't find anything, but I think it's gotten a bit worse and I'm planning to take it in again before the 4-yr warranty expires. Can you describe the location of the loose bolt you had?

I didn't see where it was.
But the clunking noise is back so that wasn't the problem.
Like you I am taking it back again.
Maybe this time I will take it to a different dealer.

After the second dealer checked out my noise concerns they could not find anything wrong.
Said they checked all the strut mounts, engines mounts, ball joints, and suspension throughout.
No idea what could be causing the noise it seems only I can hear.

I have a feeling the same thing is going to happen to me.

I took it back in about a month ago and they said the front passenger side strut was bad. They replaced it and the noise is gone.

Wel we just bought a brand new 2023 Avenir, and any speed after 55 mph the underside passenger and drivers side has a noise from the rear mounting area of the front seats up to the front footwell, also the push button start switch metal cover came off, looks like the 'PINS" were not pushed down. Hopefully we are not sorry for buying this Buick
