Purchased this vehicle from a reputable independent dealer in May 2015. Love the vehicle and the Mars red color. After a couple days noticed problems on the truck with the discoloration under the clear coat. Had it checked out to be sure the car had not been painted. Took to two collision centers who confirmed that the problem was a factory/paint defect. The factory warranty ended on December 30, 2015. My vehicle has 22000 miles currently and Mercedes position is that my warranty has expired and although there are no recalls other vehicles which are the Mars red color have been repainted by Mercedes because of a factory defect and my vehicle which was purchased 5 months after the warranty expired will not be covered totally or partially for a repaint at all by Mercedes USA. So much for their adds of "Excellence or Nothing". If you have a similar problem please post you problem as this will help our lawyers help us!
