Took it to the local dealer today to have the battery checked. Just called back with results that a new battery will be ordered.

Dealer emailed that the "power train warantee" group has not analyzed the test results from last Monday's battery tests - have not heard back on the replacement. I did get the Leaf back - with all 8 bars showing - not change there. Is there a number to call directly about what is going on? Has anyone experienced this type of wait for Nissan to make up there mind if they will honor a clearly stated warantee? Again, the dealer has promised to send the detailed test data - whatever that is. I get the impression that the service adviser knows little about the Leaf - he told me that my Leaf had only "6 bars" after the test. I told him that you must count the red bars also :?

My only significant wait was three days to find out if they were going to provide good will replacement.
But I was two weeks past five years.

My guess is they may be busy with lots of warranty claims.

But dealer might have sent to wrong Nissan group.

You could call the EV customer support number.
But I think it would be better to stay with working through the dealer.

Might have been better to use dealer with replacement experience though.

FWIW it was literally the next morning that my dealer last spring heard back that it was approved. Maybe Nissan corporate is behind on reviewing things? Or the dealer is messing things up but I'd wait to see what happens on Monday.

Do this 10-15 times and you will lose 3-4 Ahr.

You will need access to a DCQC. The DCQC will literally cook your battery.

Finally heard back that they will replace the battery under warranty. It will take 12-14 weeks for the battery to arrive. I'll post the metrics as soon as I get the correct iphone dongle. I'll update any progress.

I just got Leaf Spy and am glad I did! I am currently at 9 bars with AHr = 41.68, SOH = 63%, Hx = 42.26% on a 2012 with 33k miles on it. I look forward to a new battery, especially in the Vegas heat!

You don't say when your warranty expires but if you have the calendar time if I were you I would stop driving the car now leaving it plugged in, with the climate control timer set to go off everyday. THis will do four things. First it'll keep the 12 volt battery charged, then it'll keep the traction battery at a relatively high SOC, and it'll cause the battery to cycle a bit as the climate control while plugged in does this pattern of discharging the battery and then charging it back up, and it will keep the inside nice and dry. Then figure out how many miles you can drive it per week such that the calendar warranty expiration and the mileage expiration line up. This will allow you to continue to monitor the progression of the battery capacity degradation.
