I have a 2016 CLA45. It has 13,000 kms on it and hasn't gotten it's first oil change yet.

I'm having issus with the front left wheel area. When driving at 120 kmph which is around 80mph, it makes a low rumbling noise that vibrates the footwell area. It happens when going straight or zigzag. It's on and off as well. It will groan for 10 seconds and let off for like 5 seconds and start to groan again. It doesn't matter if the surface is smooth or bumpy either. At first I thought it was a original summer tires, but now I have winter tires on new rims and it still does it. It has happened since day 1, but it's finally getting on my nerves now that I know it's not the tires. What can it be? Wheel bearing? Suspension? Alignment?

Thanks!

You are talking to the wrong group-----you should be talking with a service rep at the dealer you purchased the car!!

Check the wheel bolt torque is correct to spec first...
This being low can make a similar noise.


Besides that back to dealer.


Once you know the fix do post back, it helps others..

Since it appears the wheels have recently been off, recommend you first check lug nut torque.

If lug nut torque is as specified my guess is a failing wheel hub bearing. As posted above you need to have the hub replaced before it fails completely and you find yourself immobile on the shoulder.
