I too have been getting intermittent episodes of reduced power output in cold weather under acceleration or high speed. My battery is at 66.5% Was down to 65.3%, but I needed to fast charge to get home the other day, and it bumped back to 67% Lots of variation showing in the cell charges. I am not too savy in understanding much of LeafSpy information.
I've been reading here, and I had been assuming that I was getting close to dropping the 4th bar and thereafter would be getting a new battery. So I ignored the semi-turtle events.
Then yesterday afternoon, 2 bat temp bars, 20 deg F, 68% battery charge, I am doing 65,mph on a slight upward incline. I feel it reduce power and slow some, did not pay much attention to dash initially.
THEN, car loses ALL power. Lights on dash all light up including a check engine light I've not seen before. The nice voice announces I should pull over (still coasting at this point" and set the Parking Brake. I later find that the car has defaulted to Neutral.
Was able to get off the interstate. I failed to take pictures of the various error messages (was getting out of traffic and making a lot of driving decisions). But on the side of the road, I shut down the Leaf and restarted. No changes. Still multiple error lights. Woud not shift into D. Climate control giving no heat (could not hear heat pump). Heated seat interesting still functional.
4.2 Miles from dealer where I originally purchased and AAA member, so 45 minutes later I handed the key fob to the dealer service guy and that was that. Their Leaf technician has weekend off. Will know more on Monday. I did not try to look at things with LeafSpy or my other OBDII diagnostic program. I was freezing, as I had no heat and only was wearing scrubs and light jacket......
I have not read where anyone else was having the cold weather turtle/reduction of power where the vehicle actually finally died. We will see. I will post more when I know more. Perhaps will get my new battery soon.....
