Bought a 2017 C300 with 4.5k miles on it. It was a loaner vehicle. Whenever the fan is at more than medium speed it is loud with fast vibrations resonating through the dashboard and steering wheel. After the car cools down it slows and goes away but its quite obnoxious.

Anyone else experience this? My dealer said its normal and my loaner did the same thing.

Thoughts? Am I crazy?

Normal - turn fan down to 5 - then 4 - lower speeds noise/vibration goes away
