I just took my vehicle in for its 20k maintenance at the dealership Monday, I get my car back and there is a loud humming (possibly slight grinding) noise coming from the front driver side wheel I can hear while driving at all speeds that started after the appointment. They rotated the tires and from what I’ve been reading it could be a wheel bearing, calipers touching, or my car has cancer... has anyone had any issues or insight.

Thanks

You should've taken the car back and tell them what you are experiencing/hearing, they should be able to resolve since it sounds like it was apparent only after they messed with it. Don't wait too long.

Is it constant or based on rotation speed? I have similar experience but mine's more of a wuwuwuwu or whomwhomwhomwhom, however you can phonetic that out.

Take it back ... the may have overtightened .. somthng got under the wheel hub ... lots of things can happen

I have the same exact rotational sound. Did you ever figure out what it’s from? I’m thinking it’s the tires…

Did your noise start right after a shop had it as that was the issue above. Otherwise it is usually from either tires, or bad wheel bearings, or other suspension wear or damage. How old and how much wear is on your tires? Do they have uneven wear?
It helps to provide the model year and mileage on your CT.
A good independent repair shop should be able to diagnose this problem. Don't go to the dealer.
