I have an 09 granturismo and had the sticky button issue like everyone else. Maserati finally acknowledged it and will be paying 3500 of 3800 to fix this issue i had to initially go by the dealer to have them submit to maserati. Maserati took a week for approvals and I dropped off today. I will post before and after pics as soon as I get it back. I haven't heard anyone else getting this done so I thought I would pass along. FYI it was not under any kind of warranty and I did not buy from dealer. Thought I would pass along the good news!
