While driving on a winding stretch of a two lane highway my 350Z went into an unexpected 360 degree spin. It was a little misty outside. The road was damp, but not wet. The temperature was in the low 40's deg F. I was traveling at about 45 mph in a 45 mph zone. I had just barely started into an average left turn (I.e., not a tight turn) when the car started to spin. I took my foot off the accelerator, but did not brake. I turned the steering wheel opposite of the direction of the spin, but the car did not straighten out. When it appeared I was going to run into the side of mountain head on, I turned the steering wheel in the direction of the spin, which, as expected, caused it to spin a little faster. The car ended up on the shoulder of the opposite lane. Fortunately, I didn't hit anything. I checked the tires afterward and they appeared normal. I went back over the section of road, but saw nothing unusual. This happened about three weeks ago. I haven't noticed anything since then, but I haven't pushed it either. To me it seems this should not have happened and that even if it did, the dynamic stability control system should have straightened the car out. I have owned this car for more than 4 years. From my experience under normal circumstances I should have been able to easily have negotiated this turn at least 15 mph faster than I was driving. This is a road that I travel often. I took the car to the dealer and gave them copies of similar NHTSA complaints for this car. The dealer was unaware of a generic problem that would cause this problem. The dealer will check with the Nissan rep and get back to me.
