Hello, my Colt has a strange driving behaviour when driving open. In unevenness the car trembles, which is also noticeable on the steering wheel. As if one or more shock absorbers are completely worn out. But can’t actually be, the car is new. If the roof is closed, it drives quite normal. Today, after some re-checking on my part, new tires have been installed. It may be that the driving behavior has improved a little bit. But the way is not trembling. Do you have other convertible driving he did the same with your Colt???
