What Version Software Is In Your Leaf + "a/c lockup" ??

[AmarilloLeaf]

I am beginning to think that there is more than simply changing from rev C to B at play here. More than one poster has had the lock-up, has not had a software update, and is on version B. Others that have had the update are also on B. And nobody is reporting rev C.

There may be some other patch involved. It sure would be nice if someone on the inside at Nissan was here to explain this.

I for one want to know what the point of the move from the A version of the bios to the B and then to the C was supposed to accomplish.

Good luck getting that from Nissan -- talk about proprietary!

hah - was just about to do the same poll - #728 is running B.

847 running "B"

[rawhog]

868 "B"

[LindaK]

Vin #351 running "B" after being "fixed". Don't know what it was before.

[Boomer23]

889 and "B".

Mine is the unusual situation of not having had the AC lockup problem, but my car was called in to my PD, Connell Nissan, for a software update because of the potential for the AC problem. I didn't know about the version display prior to my software update, so I don't know what version my car came with.

Looking back at the situations that others had reported, I had never pre-cooled nor turned on the AC while in ACC mode, so I never created the reported failure condition. I had driven about 30 miles with AC on, though, and had no problems with the car.

VIN 716.

Delivery April 2 12noon, 16 miles.

Problem, April 2, 4pm, 34 miles.

Dealer resolved issue on April 4-6. Retook delivery April 7, 11am, 51 miles.

Now I've got 204 miles on the clock

From the poll, looks like nobody has the "C" version? Are the "C" versions being reprogrammed to "B" at the port and/or by dealers before being released?

As for the VIN #, that would be helpful to find the grouping with the problem (if there is one), but has anyone confirmed that the VIN # denotes the order that they were produced at the factory??

I was told directly by Brendan Jones at Nissan corporate that the cars are NOT produced in exact VIN order at the factory. Not sure how much variance in sequence is normal for operations, and I'm sure there is a broad correlation between low VINs and early production and high VINs and later production, but there is no exact correspondence to production order. They are definitely "batched" in some way.

My car is #1317 and it is running Part# 3NAOB. No lockups after 150 miles w/ maybe 10% of those using A/C, but we have never pre-cooled the car.
