A week after I purchased my new QX56 I took it to the car wash. The day after that I was looking at the car and spoted to marks on the side of the truck! I took it back to the car wash show them and they promised me that these were not marks made by their wash. They buffed it out anyway free of charge. They told us to go through the wash again and take a picture before and after. Just like the first time the same mark appeared after the wash, they appologized and buffed it out again! W do not get the truck washed there anymore. I am very careful of where I get my truck washed now. Did anyone else have this happen to them in their QX56?
