We purchased a brand new 2010 Rogue on May 19, 2010. Recently noticed the muffler looking like it was rusted. Took the vehicle in for it to be looked at, was told by the service dept and by the manager that nothing could be done. It was not defective in anyway but only discolored and therefore was not considered a problem. WELL, this is a brand new vehicle and in my opinion with a price tag of near $26, 0000.00 that the muffler should not look old, trashy and used ! the muffler is not hid under the vehicle and can be seen from the rear. I was told it was stainless steel. I don't feel like stainless steel should show signs of discoloration on a car that is brand new. I have only had this vehicle for a little over a month. I feel that the muffler should have been replaced with a new one. The dealership would not do it, stating the dark areas are weld marks. THIS IS NOT TRUE. It is more than just dark areas !!! They said verbally it was discoloration. The form we states dark areas from welding. I was treated like royality until the papers were signed and the vehicle was mine.
