Whine/Noise/High Pitch Arg!

maniacdave

Hello, I got my Z about 7-8 months ago, model 2009 (it was a dealership showroom model, had 12 miles when new). So it's purchased with a slight discount, but comes with full warranty.

A week ago, I started to hear a high pitched whine, exactly the kind of noise sub-par capacitors often do. It's now gotten so loud that I can't drive the car anymore. I have very sensitive ears and this noise gives me a real headache, plus I hear its echo half an hour after I get out of the car. It's a BIG problem. I'm going to have to borrow a temporary car until this is fixed.

It started just recently, I have 2300 miles on it. The car finally settled, is a lot more fuel efficient than it was new, the gearbox is precise yet smoother... In short, I was beginning to be really satisfied with it. Now this fresh hell turns up!

Once the car gets warm (15mins after being cold) it starts and doesn't let off. It's present only while the engine is running. Accu on / engine off - no noise. RPMs have no effect on it. I start the engine, the noise welcomes me and drives a spike into my BRAIN.

I'm in the Czech Republic and we have a really long history of bad & unhelpful dealerships. They basically label everything OK, "nothing to fix here", move on. I'm really afraid I'll be stuck with it and will have to sell the car.

Does anybody have any solid facts, hints, technical pearls about this? How should I approach them? How can I prove this issue? I'm sure the dealer will try to deny hearing anything. Does NISSAN have some kind of a list with known issues? Does NISSAN acknowledge this at all?

THANKS!!
