I think we will figure out which firmware is to blame quick enough.

Perhaps, but sometimes these types of problems only occur with a specific set of firmwares loaded. Also, my experience tells me that Nissan revs the firmware for these updates over time, so I suspect those who are getting it today may get different versions than what others of us received in back in March and April. (Of course, that does not explain OP's issue since his was done back then.)

I guess I'm hopeful to avoid helping Nissan debug this particular problem! :shock:

I have no idea what they called it, it was the one that came out in Feb 2012.

They wanted to do the update when I took my car in for one year battery check mid-June. I refused the update, reasoning that since there was nothing wrong with my car there was no benefit to the update and some risk involved. Perhaps I guessed right. They aren't going to touch my car for this "update" with these reports.

It was the February update (voluntary safety recall) in my case as well. I didn't bother with it earlier, but the dealer insisted. The download and installation took a while, had to leave the car overnight. This software didn't fix the CarWings inaccuracy, one of my pet peeves, and had no perceived benefit, at least from what I can tell.

That update, for me at least, was actually two. One for the car and one for the Nav. The Nav update went wonky too and they had to re-flash it to fix it. Too bad they can't do the same for the car.

Can you look on the paperwork and get the specific nomenclature for your update?

Too bad about the level of service. I think that directly relates to the dealer. This car is so new that when I had the first update that solved the A/C problem of shutting down the vehicle, a regional tech drove 200 miles to my local Nissan dealer that is not LEAF certified. Spent an hour updating the software and left. The dealership even let me back to the repair shop to watch and talk to the tech. While he was working on the car I overheard one of the mechanics concern that if this was the way cars were going, he was going to be out of a job because he has only had training and experience on mechanical things.

The next update was at the dealership. Now I'm dealing with dealership mechanics, not regional ones. Anyway, they couldn't get the software update installed correctly after we sat for a couple or three hours. They then gave us a loaner car so they could keep the LEAF overnight. We came back the next day and the service rep said they finally got the software properly installed just a short time after we left. The car works fine and we never experienced any of what you have.

I suspect that between the difficulty of getting mechanics that have been trained properly and have built up experience in addition to a perhaps bad connection or bad EEPROM that may be what has happened in your case. I am surprised however that Nissan isn't swarming all over your car and even flying in techs from Japan. They used to do that.

O.K. The February update is the one I specified.

Yep, the February update does not fix the CarWings problem. That is only fixed by NTB11-041a. I FINALLY got permission from Nissan for my dealer to apply that to our car. Waiting on the SD card with the firmware to arrive.

Interestingly, when I recently tried to get my dealer to apply NTB-041a they tried to reapply the February update and it *attempted* to update further but my car apparently did not accept the update. Perhaps it is good that it failed. I was furious enough that they didn't fix my CarWings problem, but I cannot imagine how mad I would have been if they had messed up the car! I can give more details on the failed update if desired, but I don't think it applies to OP's case.
