 I brought this car brand new in 2006.  Around 40,000 miles the transmission started to slip.  I called the dealership and of course they said there are no issues with the transmission, this is the first time we've heard of this, yeah right.  Called 1-800-Nissan but they weren't any help either.  I had all my service records but I just didn't get the car serviced at the dealership so they said there was nothing they could do since the dealership didn't service the car.  82000 miles in rush hour traffic the transmission goes completely out.  The car was towed to the dealership who gave me a discount and put in a new transmission for $3,200.
