I just purchased a 2015 C300 4matic 3 weeks ago. At speeds above 70 the wind noise is very problematic, to the point that I now wear earplugs when Iím on the highway. Car has 15,000 miles.
I downloaded a noise level app on my phone. Recorded 84.7 dB at 76 mph. Ridiculous.
I commute 150 miles r/t, 90% at highway speeds, and have driven a Honda Fit, BMW 1 Series, and a Porsche Macan S on this route for the last eight years. None even approach this C300 in terms of wind noise. I even rented a Nissan Sentra last week on a trip and it was significantly quieter than this car.
Dealer said they will fix it. If not, Iíll need to return the car for something better. Iíll report what happens.
