Flapping noise with convertible top

The day I picked up my new cabriolet, I noticed a flapping noise at the upper rear corner on the passenger side of the vehicle at highway speeds. I have brought the vehicle back to the the place of purchase. They have attempted twice to correct the problem by tightening the "tension strings" but to no success. I still have the same noise, a little less at best. I am waiting for the dealer to call me back when they have a loaner vehicle so that I may bring it back to them to see if they are able to finally correct the situation. Has anyone had a similar problem?

Still waiting for the dealer to call me to supply me with a loaner while I bring back my cabriolet to have them look at that "flapping" noise again. They promised me this about two months ago...

Hey Karl. I posted a response on your page. Good luck!

Well you're right about it being a predominantly passenger side kind of thing. The flapping got kind of annoyiing one day, so I leaned over to look out of the rt. rear view mirror to find the Brabus B decal flapping away ready to escape like a frisby from the gas tank door.. I rescued it and a replacement is supposed to be on order. Back to Cabrio top.... I plan to do a little small scale wind tunnel study with my leaf blower. Some of the flapping seems to be in the door panel. I will try to experiment before going to work at noon Saturday and let you know what I am able to blow up. :)

You're right...it is quite distracting and annoying, especially since my Smart currently has less than 1700 miles on it. For some reason, the tension on the passenger side is noticeably looser than the driver's side by feel to the touch. Could it be a defect in the ragtop for a select few? Can't be endemic because it's definitely not a problem for the smart cabriolet loaner. Besides, I don't notice too many complaints about this condition on this website.

Karl,
I had a cabrio loaner for a week now and it does the same as you say. I was disturbed by it but it is the dealers car not mine. The flapping is quite distracting when I am driving. I am glad I have a coupe. Hope your situation is fixed. Good luck!

Mine does it too, the dealer never could isolate the problem. It only rattles on the right rear ribs of the convertable top. Let me know if you discover the cure, it is annoying at times.

I would accept it as normal except that it NEVER occurs on the driver's side. Also, the flapping is fairly persistent even on calm days without wind. One final thing...when I had my smart serviced at the dealer I've been loaned "their" smart cabriolet which rarely (only during wind gusts) if ever experienced this flapping noise.

Carl,

I experience some noise in crosswinds, caused by the fact that the edges can lift away slightly, I suspect due to the slight lift caused by the air passage over the curved (like a wing) lift. It's never been serious, and I think it's endemic to the fabric top design.
