My cars is only five months old, but the top has started to squeak much more than what I consider to be acceptable. Over rough roads with the top up, it can actually be heard at 70mph with the radio on.

Has anyone else experienced this problem? It's not just the latch rattling... it's the entire frame of the roof. Would this be covered under warranty?

 

should be covered without a doubt IMO

 

Probably,only needs an adjustment.!

 

Get a tube of Shin-Etsu grease from your dealer or, better yet, H&A (cheaper).
Works wonders on all the rubber seals. I use it occasionally on the windshield header and it's been quiet ever since. Your car is new so the dealer should take care of it for you anyway. Assuming, of course, that that's your problem. It's a handy thing to have for any car.
