2018 CLA250
Did you resolve your humming noise? We have a 2018 CLA250 that just started this noise - 50,900 miles. Once we hit 60mph, the noise starts and stays a constant humming sound/pitch regardless of rpm, gear, acceleration. Noise starts to go away when we slow down lower than 40mph, but picks back up once we accelerate again above 60. Any help is appreciated.

Hi There! I registered for this forum to problem solve a humming noise I am experiencing similar to what you have described. I use a Mac and am not able to view the humming clip by the OP. Was your humming noise anything like this?
The dealership so far is blaming it on the tires and suggesting I replace all 4 tires at my expense. The car has 20,000 miles and I have only put 6k on it since purchase last December.

It’s the exact same noise I heard on the attached movie clip. Only mine is very precise between 48-52 mph while coasting. The foot must be off the accelerator at this speed. Dealer claims all cars suffer in this regard. Not true. I have a 2018 GLC 300 which runs great. No noise
