My 2017 Prime Cabrio makes a high pitched whistle that is so loud it drowns out the radio and drives my dog crazy. It happens at freeway speeds in a side wind. I asked the dealer to check the seals and the top generally to make sure everything was in order and they said it was fine. Is this normal? Does anyone know of a fix other than just getting ear muffs for the dog? 馃ぃ

Our 2017 Cabrio is relatively quiet at speed with the top down or up .. yes must have a bad seal somewhere allowing wind to do the whistle effect .

You may still be under warranty. Take it to a MBZ dealership service dept. that also services smart cars. If the warranty recently expired, call the mothership and see if they will offer you good faith warranty coverage. Hopefully, that little wind deflector the sits on the center of the windshield header is still in place?

My 453 Cabrio 2019, is very quiet with the roof up, so you definitely have a problem with seals. You did not say where the noise is coming from , above? to left or right, front or back of side doors? or rear? That would help narrow it down for us to say what seal is causing the problem. as said try to get it done under warranty. In the past on other makes of convertibles I have used silicon grease on dodgy seals to stop rain ingress and wind noise.

I have solved this issue with a plastic strip that made by a Japan company, look it up on my 451 posts.
I have just purchased a 453, same issue.....gonna put it on this weekend.
