Hum when turning at slow speed
I have noticed a deep humming noise when turning right into my driveway in my GL 63 (X166). We have 63k miles on this MY2015. Any guesses on what this might be?

Raise the suspension and try the same turn at the same speed. Also check your wheel well liners to see if there are any rub marks. Do you have aftermarket wheels or larger-than-stock tires? My tires are slightly larger than stock, and rub a tiny bit on sharp turns into driveways or parking lots.
Humming can be wheel bearings. I haven't had to replace mine yet on my GL, but I have on other cars and there was a definite hum at certain speeds. Listen for a stronger hum on one side than the other, depending on which way you're turning. Sit in the passenger seat while someone else drives the same turns and see if you can hear it better.
