It's 99% certainly a wheel bearing and hub. Need to verify which. Get new replacement wheel-hub-screws too.

It's DIY do-able in the garage and there are year-specific youtube help videos so search your specific and you'll notice the model year range for the work.

Or a shop can do it. Not saying your oil change shop can do it. You know what I mean.

Griz, would acceleration make it worse, make the noise louder? Sounds like a scraping when I hit the gas.
I will mention this next shop visit.

The guy I talked to last shop visit said it's a huge job and exciting naive and said to not do it unless it's impacting the feel and handling.
Not saying that's right or a good Idea, but that's what he said.
 
From your posts over these two months it certainly sounds like acceleration is efficiently grinding it's way further into your wallet.
 
I'll see the mechanic next week.
It seems odd it would be something with wheel since tapping the gas pedal, makes the sound so loud and exaggerated

What's odd is this is totally different, the target is moving so I'm tapping out.

It's not a whine or a growl.
If anything it's a grinding or rubbing noise that gets much word when you hit the gas. Best I can do is have them listen again.
Last time they said it's common on the Impala. No idea beyond that. :(
I know I'll never buy one again and makes me nervous about Chevy since they say it's a known problem with the bearings.

I just thought of this...MAYBE it's the interior brake pads are wearing out evenly. I remember many years on my '15 LTZ I had an issue kinda what you had, I couldn't figure out this odd grinding sound and just thought it was a small rock (like gravel) that was stuck between the pads and rotors. I checked all the rotors and brake pads for damage but nothing. The sound got worse and one day the front wheels seized. Well it ended up being there was damage on inside rotors. I never bothered to check the inside pads and rotors for any damage and unbeknownst to me the inside brake pads were wearing out because the old grease on the calipers slider pins caused them not to retract and the pads wore down to the metal. Check the inside of the rotors and pads for any damage and also check the pads for even wear. If you find any abnormal wear clean and re-grease the caliper pins. Possibly get new pads if it's really bad. Hope this info helps.
 
@Guitarguy14 Hi, so I’m experiencing the same exact thing right now with my 16 Impala. The sound is hard to describe but kinda sounds like a truck with big tires kinda. When i decrease speed you can here in wind down and almost sound like exhaust but i doubt it. Did you ever find out what the issue was? Thanks!

I’m buying one (cheap) that’s been making this noise for the last two years. It can’t be a wheel or hub bearing if it’s making this noise without failing over that time. The transmission fluid looked pretty worn and my best guess is an internal transmission bearing (3.5l FWD) because the sound isn’t directional either.
