as with all mechanical/electrical parts, there is always someone who will get THAT part that fails. it inevitable, someone will have a problem. but its usually aftermarket sunroofs that have this problem. i used to install them, so i have had experience in this area. if components didnt fail, there would never be any recalls and all vehicles would last forever. things wear out and go bad, some quicker than others, and sometimes its a manufacturing defect. it happens. but in general, its always best to go with oem features such as this because that means the vehicle was designed for it.
