Outdoor temp: 21F
Pack temp: 53F
I had ZERO regen bubbles until I was at 3 bars, and 9 miles on the GOM. At the point I finally got the first bubble, LEAFSpy reported SOC at 35%.
Yep, that's precisely the behavior I get in winter since the P3227 update. I can only surmise that Nissan was seeing significant plating of elemental lithium onto the cathode during cold-temperature charging to warrant such a drastic reduction in regeneration.
But the P3227 update is not directly related to grabbiness of the brakes. That issue was addressed by "PX65AA Recalibration" according to the paperwork for my 2011 LEAF. That said, I find that grabbiness tends to be much worse when there is rust on the brake discs. Since the P3227 update for the battery, we find we need to apply the brakes much more often, so that does tend to Reduce the grabbiness somewhat.
