Re: 2011 Leaf, battery near 8 year/100k warranty - Question

Thu Jul 18, 2019 6:16 pm

Since the car charges at both L2 and DCQC, there is probably nothing wrong with the car's onboard charging system. The EV system error light on the dash could be an indication of a failure (such as weak cells) that is covered by the 8-year, 100,000-mile battery defect warranty. The best course of action would be to get Leaf Spy Pro and a suitable Bluetooth adapter so you can read the error codes. Report the error codes along with cell-pair voltage graphs back to this thread so we can give you some more recommendations.

Yep, the error codes and doing the rough equivalent of the CVLI test can help. If the latter fails, you can try to argue to get the dealer to the replace the bad modules, if any.

Google for site:mynissanleaf.com cvli.

https://www.mynissanleaf.com/viewtopic.php?t=21700 was an example of a Leaf w/a bad module. The 2nd driver was able to get his dealer to fix it. (I actually know JeremyW a bit and have talked to him in person on several occasions. He added me as a FB friend awhile ago.)

Hi all,

Following up to this thread (and thanks for the helpful replies so far - this is the OP, but can’t figure out how to log back in).

Could anyone be kind enough to help me interpret this info from the LeafSpy app about OBD codes and battery health?

With the warranty expiring soon, I went ahead and dropped the Leaf off for a service appointment next week, but the technician went ahead and looked at the car after they had an appointment open up (I was hoping to have insight on this LeafSpy app info before the appointment). The technician noted the P33D4 code that he believed to be associated with the yellow car/exclamation point icon on the dashboard and related to capacity loss, but he said he didn’t notice anything on his initial look that would necessitate further testing.

OBD Code readouts/log from LeafSpy Pro app:

Additional LeafSpy screenshots that it seemed might be relevant, some I think relating to battery cell health: https://www.flickr.com/photos/183155543@N06/
(most of these were taken when the car was down to about 8 miles remaining after a 15 mile highway drive, but a few were taken with near full battery before the drive - several of the photos might have redundant info in them, sorry about that)

Thanks to all for any help and insight, I think Monday might be the last day I can get the dealership folks to take a closer look at the battery’s health. Going to take a deeper dive into the info cwerdna posted as well.

Most likely the 12 volt battery is failing. If it's more than 3 years old, I suggest a new AGM type battery, fully charged before installation. Clear the codes (it may take several tries) after that, and see if any come back.

Yes. This. Either you have a bad 12v battery, massive number of failures of unrelated systems, or a problem with the communication bus.

99% chance its the 12v battery. Swap that out asap with an AGM as Leftie suggested. If the dealer tells you to swap the battery, ask for an AGM. They're a lot more expensive but will work much better in the Leaf.

If you expect the car to only be in your possession a few more years, a new non-AGM battery will also work. Just make sure it gets charged fully before installation, because Leafs don't always charge their 12 volt batteries well. The OEM battery for newer Leafs isn't very good, just acceptable. Don't pay a dealership premium for one.
