Owners here in New Zealand are also seeing the earlier stages of degradation in 2016 cars based on Leaf Spy and loss of first bar while the 24kWh cars are reporting better. There is a question of whether the loss of range is equating to the loss of SoH and posts here with lots of bars loss tend to show significant loss of range. Has anyone done range loss comparisons as the bars are going? Your warranty is still based on bars and with 4 bars loss the range reduction does seem high.

I've got a '17 S with 17k miles on it, no bars lost yet.

Here's my plan, though - I want to get it to 99,990 miles as soon as possible, then leave it charged in the sun for a year or so. Boom, new 100k mile battery.

You're in Denver, you might be unlucky and end up up with a 61% SOH battery and only 3 bars lost still before the warranty expires! :D

I suspect Nissan is having the dealership run special diagnostic software on your car because this is one of the first warranty claims with the 30-kWh battery. Hopefully they are compensating you for loaning them your vehicle while they play with it.

Do Nissan dealers log the use of their CHADEMOs? If not, if you wanted to abuse your battery, Denver gets pretty warm in the summer. Drive at 85 MPH up I-70 to Genesee Park (a steep climb) on a summer afternoon, zip back down to C-470, repeat until empty, then CHADEMO at Empire Nissan. You could pull this off at least twice in a day. That oughta heat the pack to a dull red glow.

Not that I'm endorsing this behavior, but the potential is there if someone thinks they need to do it.

Not a good idea to get too hot as Nissan can see what you have done. Look at battery temperature in table at http://www.mynissanleaf.com/viewtopic.p ... 52#p182552

Welps, there goes the "park it fully charged under the sun" idea. Thanks for sharing that topic! Never knew that they had such info.

Re: 2016-2017 model year 30 kWh bar losers and capacity losses

As to range loss: When I lost a bar in Nov, I started logging range estimated vs actual on each charge. My SOC was about 81%. I found that if I multiplied the EPA rated range of 107mi (which was what I got when the car was new) times the 81%, that was pretty close to what I would get.

Another observation was that when the car was new, the GOM was VERY accurate and consistent. After the loss of a bar, it was overly optimistic and unreliable. It was estimating a range more like 1/12 of the 107 mi EPA range when new.

Without LeafSpy, and this forum, I would have assumed one bar would equate to about 8.5% of capacity. As discussed in this thread, the first bar doesn't drop until more like a 15% loss. So the bar system is misleading at best.

I've recently turned in my '16 30kWh car at the end of the 2 year lease. I'd have been willing to buy it or extend the lease if they would have renegotiated the terms. The lease company said they don't extend leases except for 3 months while you get a new car. And the end of lease inspector said Nissan doesn't negotiate end of lease buy out price, even it they have to sell if for way less after they get it back.

Nissan dealers can negotiate the price, to see how much of a given month's incentive they can keep for themselves. NMAC no longer offers the incentives to owners, only to the dealers.
