I am so Fn done with dealer service Dept.

Read the TSB (that Trip already posted). If they look like the picture on the right, you have the wrong ones and they will eventually break - and more than likely get stuck on the wheel requiring a time consuming and potentially expensive removal.

Here it is again.
TSB: 2009 nissan 370z / 350z; accessory locking wheel nuts

Also it is not that they are faulty, they just aren't designed for this car. Dealers are just assuming that the 370Z and the 350Z will share just about all the same parts but that is not the case on many of the finer details.
