Dealer says they were unable to reproduce it. Which is what I expected, since I wasn't able to either. Chalked it up to a fluke. They said they found codes, cleared them, and told me to come back if it happens again.
My specific problem has come back. Within the past 9 months it's happened at least 10 times. It's always the same condition too - within 1-2 seconds of a hard acceleration from a dead stop on a slight incline. Within 5-30 seconds a BSW Malfunction warning usually also comes on.
Independent mechanic said after digging around the only code they found was P17F0, which if the customer complains of judder would indicate that the CVT needs to be replaced. I'm pretty doubtful of the CVT being the issue. I haven't noticed any judder, and I can drive at 80+ MPH on the Interstate up through the Appalachians and the car doesn't skip a beat. It's only doing this from a dead stop. The Nissan dealership did put the incorrect fluid (NS-2 instead of NS-3) when I had it serviced at 60k. It's printed on the receipt and when I asked them about it they essentially said "the fluid in your car was green so we replaced it with NS-2 which is green; NS-3 is blue". The manual and all TSBs state never to use anything besides NS-3. If it really is the transmission then I guess I'll have to get them to pay for the error, but I don't think it is since the car drives fine otherwise.
One time it did this and the AWD Lock system engaged as well. I only noticed this because after a few minutes of driving the system warned me of AWD Overheat and to stop immediately. There is no documented feature of the car automatically engaging AWD Lock, and the car will not allow you to engage it above 25mph. If you engage it and drive over 25mph, it will turn it off. Even restarting the car didn't fix it this time - the car kept randomly turning AWD Lock on and off for the next 10 miles until I could stop at a gas station and borrow a pliers. Disconnecting the battery corrected that issue.
Because of all this, I'm leaning towards some kind of computer or electrical fault. Possibly with the Chassis Control Module or any wiring going to that. Anyone have any guesses?
