Re: Lost a bar (capacity loss) in a 9 month old 2017 Leaf

Sun Dec 10, 2017 2:20 pm

I have a 2017 Leaf (used to have a 2013) and I have 12k miles on it now. No bar loss. We hardly ever charge to 100% but QC every day. I don't think QC is as big a problem as charging the car to 100%, and with your post, that further solidifies that presumption.

Yes, I see your point. It's easy with QC as it doesn't go till 100% but with home charging at L2 there is no way to stop it at a certain %.

What's your location?
2014 S/QC - dropped the first bar at 28K miles, second at 32.5K miles, Lease ended in April '17.

2017 S/QC - Lost two bars already (at 9,6K miles and 14K miles). Going back in April '19.

He's obviously well on his way to getting a replacement.

Yowza! I see you're in a hotter part of CA. At this rate, I think you'll be down to 8 bars by mid-July 2018, if not well before.

Out of curiosity, what's the build month? It's on the driver's side door sticker.

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

Build month: Nov 2015

Only 10 miles on the car during the ~5 months between manufacture and lease. Do not recall the state of charge when we took possession of the car. Would have only been exposed to cool winter months at these latitudes in the northern hemisphere during that time.

Should add that the Leaf could have been down to 9 bars for at least the last few months. The wife is no enthusiast and just drives the car and did not know how the bars worked; I rarely drive the Leaf.

I had no reason to suspect advanced battery deterioration until she pointed out the decreased driving range a few weeks back then caught the 9 bars.

Anticipated some battery degradation, but never guessed we would have the battery replaced during the 3-year lease, I'm guessing (8 bars) could be in the next few months, but with these cool temperatures, may not happen until spring/summer.

We leased a 2016 LEAF with a 30 kWh battery in August 2016. Date stamped inside door panel is 12/15. We are located in Austin, TX.

We lost our first bar in August 2017 after 12 months of ownership, at just under 15,000 miles.
We just lost our 2nd bar yesterday at 17,890 miles.

We've had the car for 16 months and already lost two bars. Our fully charged range on the GOM is now around 75-80 miles down from the 110-120 we saw when it was new.

So disappointing to see all these reports of capacity loss in the new 30 kWh. Elsewhere I was reading about how the physical size of increased capacity is same and there is no thermal management which is causing this issue. Now I don't know a whole lot about these things but it concerns me if this issue will be compounded in the next version which has 40 kWh but again no thermal management.

I was looking to buy next Leaf but Bolt is starting to sound like a better option now. :( Not trying to start a Bolt v/s. Leaf thing but just venting.
