I have had mine replaced twice under warranty due to the fogging on the inside of the lens. The lights are sealed units and unfortunately can not be taken apart. The dealer and so far Maserati can not figure out what the cause of the problem is.
So if the car is no longer under warranty I would think Maserati is not continue to back their incorrectly engineered product. Has anybody ever tried to contact Maserati directly on certian items like this with any support?
