I have a refurbished 30 installed aftermarket in a 2012 – it runs fine but I’ve been hearing about the firmware update for that battery. Someone told me that a firmware update would not work on my car. The reason is that the firmware resides in both the battery pack and the car's computer, and the diagnostic equipment would recognize a conflict between the battery and car VIN’s, and therefore find them incompatible.
I called several Nissan dealers located nearby me in Los Angeles -- 2 said they would NOT work on the car for the reason above, but 2 said they could do it – 3 to 4 hours @ $175/hr.
So the 64 dollar question is this: who is right? The 2 dealers who say that because of the aftermarket installation (specifically incompatibility with the software in the car and battery), a firmware update will not work. Or the 2 dealers who say that it can be done for $500? That's an expensive gamble.
And bottom line: will it make any difference in terms of range, longevity or performance?
