When I drive with the drivers window open and the passengers window closed or put the convertible top down, the headliner pops out of the gasket that hold it in place. When visiting the Studio today, I found out that this is also happening on one of the demo convertibles. I have an appointment with the Studio on Monday to get both the headliner and the gasket replaced. I hope this solves the problem. Are any of the other Cabrio owners experiencing this same issue. I have also reported it to Fiat Customer Service and they have asked that I report back to them when the new liner is installed to make sure that solves the problem.
