Re: Taking my leaf in for Cell Voltage Loss Inspection

The service manual says they can use a bad cell voltage as high as 3.712 volts for the test.
It appears from my reading that at the higher voltages the bad cell difference is less. I noticed
the picture showed the bad cell at a lower voltage. I wonder what the numbers would be if
lowest cell is at 3.712 volts?

Thanks for being the "guinea pig" in attempting to get Nissan to take action on this issue. I'm sorry about how poorly it has gone so far. :cry: Can you please provide an update? I am interested to hear how this is playing out as I hope to make a claim against CVLI problems in the future. I have one cell-pair (37) that is degrading faster than the rest, but it does not fail CVLI unless it is well below 3.712V.

I agree that it is best to look at CVLI right after the lowest cell crosses below 3.712V. That result would be interesting.

At the same time, I'm willing to bet that the service technician looked at CVLI at much higher voltages, and that is the reason for the pass. I wonder if the Consult III equipment enforces that the test is done correctly or if there is any other way to ensure that these technicians are doing it correctly. I guess if/when I take mine in, I will attempt to insist on seeing a printout from the test showing the voltages.

Not much to report. I haven't really pursued talking to anyone else at Nissan yet. While the cell is still degrading, I've calculated the miles left on my lease and the reality is that I shouldn't be driving the car much more than just commuting. To add a bit of salt to the wound, I just got a call today from my original dealer asking when I could bring it in for an oil change. :|

Overall, I just want to remove my charger and push this thing over a bridge. Luckily in less than a year I'll be able to walk away from it at least. This car could have aged well. But not in Nissan's hands. Not with the "just lease a new one" mentality.
