Hi
We have 2013 C300. From day one the fan noise when the car is stopped goes from loud to extremely loud. The weather outside can as low as 60-70 degree Fahrenheit when it does it. We brought it back to dealership the day after we picked it up and they told us that it is normal, but I have never had or heard another car with fan noise this loud.

Am I getting BS from the dealer?

Thanks for any help,
Jay
