I don't blame you. I hate dealing with warrenty work. I've bought 3 Muranos, 2 350ZRoadsters and now the 370Z Roadster in the past 8 years from the same dealer. I have yet to have any warrenty work done. Maybe I've just been lucky, but I really have had good luck with Nissan's.
A couple of weeks ago, I had installed a cigar lighter in the Z and had used it a dozen times. One afternoon I got in the car abd drove off, but when i looked down, all the guages were dead. Just black, but the car was driving fine. I drove it straight to the dealer and they told me the cigar lighter was the culprit. Since it was my mod, the warrenty wouldn't cover it. They would give me a break and only charge $50. to change the fuse. I said, " seriously dude? This is the sixth car I've bought from you guys. Are you sure you want to go there?" He thought about it a second and told me to never mind.
I would have paid it, but damn.
Seriously though, I have had great luck with Nissan.
