They can probably replace the front side windshields with double-paned glass, and switch out your tires to non-run flats when the time comes. I have to say that a lot of the random noise issues have disappeared now that I've put ~8,000 miles on the car.

Yes these run-flat tires are very loud and not very reliable. I have a 1999 C280 with over 208K miles. I have only had two flat tires due to nail for the last 20 years I have had the car. On the 2015 C300, I have already had three flats, twice the windshield cracked from rock on the highway.

I took my 2015 C300 to the same dealer. They test drove my car and said the noise level is normal for these cars. I am thinking of investing in a noise-level meter and measure the noise in the car and then do some research to see what is considered accepted decibels in a luxury car.

Any thoughts and recommendations are welcome.

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.
Dealer replaced the front driver and passenger windows with acoustic glass at no cost. Major difference - car is now driveable at highway speeds. There is a TSB for this repair.

Thank you for the update. Do you have the TSB number for this repair? Does anyone know how to get the TSB number. Two dealers here in the Bay Area have now told me that this noise is normal.

I contacted the same dealer again and told him about the TSB. He was aware of the TSB and said that TSB only applies if the noise is excessive. He said that the head foreman tested my car and the noise level is within acceptable range so the TSB does not apply. He said I could try a different dealer....

I went to a different dealer in the Bay Area. The foreman rode with me and did find the noise excessive. They kept the car for two days and claim to replace the front driver and passenger side window glass and some other work.

It has made a big difference but still lot of road noise due to run-flat tires. There is still some wind and ambient noise, which in my opinion should not be acceptable in a high-end luxury car, especially a German car. Next time I am going to get a Lexus, I have heard very good things from the owners.

So it turns out that it is up to the discretion of the dealer. The TSB is not a recall. The Dealer guy decides if your car meets the criteria or not.

This is a perfect ground for class action suit, if there are any attorneys here!
