I took my roadster in to Cherry Hill Nissan (NJ) for an oil change and some warranty work. I complained about an intermittent problem with the left channel of the CD player dropping out. They replaced the CD player without question and without being able to get the unit to duplicate the problem. Then they spent a day and a half chasing down and eliminating several rattles, all under warranty. My thanks to Jeff and the tech and I hooked them each up with a bottle of wine.
