Based on Christchurch's "EVS Enhanced" video about replacing batteries, I went to their website, and came across this service. It was mentioned once 3 years ago on GeekZone I believe.

2011/2015 Brake Control Module Firmware Update

Nissan has released many firmware updates for the electrically-driven intelligent brake control module ... Some of these updates relate to improved performance and others to safety. Unfortunately, in New Zealand the majority of these updates have not been made available by Nissan New Zealand to their franchised dealers.

We are now aware of several cases in New Zealand of brake failure Leafs...

We already have the ability to perform these updates, but we take no satisfaction in knowing that Nissan NZ has not enabled their network of dealers to do this and they have indicated that they have no intention of doing so.

Fortunately, some freshly imported Leafs are arriving from Japan with the latest the latest firmware updates already installed, however this is the exception and we estimate that over 90% of the AZE0-0 and AZE0-1 cars have not been updated.

As a result, we will continue working to make these brake updates as accessible as possible for those in NZ that want them.

I upgraded my brake software last year on my UK 2014 leaf.when they travelled through Dunedin (or maybe one of the other companies posting on nzev on facebook)

Had sticky brakes, took 25 minutes while I had coffee and solved brake annoyance.

@afe66: What do you mean by 'sticky brakes'? How would you describe how this is exhibited?

Our Leaf's brakes are somewhat sharp in the transition between regen-induced slow-down and the actual brakes engaging, but assumed that was the way with Leafs generally - just want to be sure this is 'normal' and not potentially an issue. Ta!

Inconsistent brakes as slowing to stop in that they would catch and stop suddenly.

You can use leaf spy to find out the version number of software.

Well bugger. Some prat on the motorway smacked into another car ahead of me yesterday evening and his wing mirror smashed off and flew up and hit the top of my windscreen causing a small spiderweb crack, breaking the black plastic strip at the top of the screen, and also causing some damage to the roof paintwork.

I'm insured with AA and they've given me a choice of glass repairers - AA Autoglass, Novus, Smith & Smith.

Does anyone have any particularly good experience with any of them?

Are there any particular questions I should be asking pertinent to the Leaf i.e are there rain sensors to be aware of etc., will I be getting like for like replacement, or even will I be getting Nissan factory glass?

Thanks

If there is panel or trim damage, its not a glass repair job and you will be up for a full claim. Hope you know whose carparts hit you to avoid the excess.

Yes fortunately the guy stopped after some prompting from me, and I got his phone number which I checked by ringing.

The AA is now on the case.

My wife’s Honda Jazz finally reached a point where we were getting fed up with repairs. She uses it only to commute 14km to the station return and very occasionally to go over the hill to Lower Hutt.

We went to visit the dealers locally and she promptly fell for a Leaf. It’s a 2016 24kwh with one NZ owner and only 13,500 km on the clock. Battery health is 93.

It’s in mint order. Range is not great but it should be fine for her expected use and we have two other cars with ICE if long trips are on the agenda.

The larger battery would have been nice as would an English display that didn’t think the car was sat on a Japanese port waiting to be loaded!

That aside, it’s got heated front and rear seats, heated steering wheel, cruise control, tinted windows etc etc so we’ll see how it does over the winter.

Edit: it’s X trim level.

Congrats on your purchase. I'm sure your wife will love it.

If it is anything like my household, the leaf will end up being the main car for trips together that are within the leaf's range. (Despite us having an objectively nicer Lexus SUV in the driveway).

A battery health of 93% is amazing for a 2016 (Perhaps too good to be true, these typically degrade at about 3% a year).

More range is allways better on EV's, but it does cost $$, and little point paying for it if you don't need it. Also the (2014+) 24kWh pack degrades slower and is less prone to issues than the 30kWh pack.

Regarding the English display, you can have it converted. $120 seems to be the going rate for the little screen in the middle of the cluster, and $350 for the Head unit (Stereo).

You are correct that leaf's tend to have a fairly high specification level. Also as hatchbacks go they are fairly big and spacious. I haven't been in a winter since we got the leaf, but if yours is a G or X spec (Climate control integrated with head unit) it gets a heat pump, and is meant to do OK. (Not that it matters given such a low range requirement).

As with any EV, no waiting for it to warm up before the heater work's. Hot air from starting the car. Also you can set a departure timer so it warms the cabin prior to departure (drawing power from the grid to top up any battery used). Quite luxurious on very cold winter mornings.

I like the timer idea!

Yes I can see it being used for trips to Masterton to do shopping and so on.

The car was first registered in NZ in 2019 with about 6000 km on and has only 13,500 now so barely used really.

How long does it take to charge one from a normal domestic plug socket?

Sometimes being barely used isn't great for them if they just sit at 100% charge in a hot climate. But it seems there is a good chance your car was somewhere cool, with the battery sitting somewhere in the middle.

A concern for cars fresh out of japan is that leafspy can over report the battery health if the car has had lots of recent fast charges (lots of ex japan cars seem to have been exclusively fast charged), but given your car has been in NZ over a year, and most people in NZ slow charge at home, any glow will have largely gone.

A domestic socket at 8 Amps adds about 10km range per hour, so the 30km round trip would take 3 hours to replenish.

In the rare event that you came home with 0% battery in turtle mode, and wanted to charge to 100% for the next day, it would take something just shy of 12 hours. This situation has never come up for me. (That said, I think I will get a wall charger at some point so we can top off quicker between trips

The car itself can support 16A charging, so it can charge roughly twice as fast if you feed it from a Wall mounted EV charger (or a caravan socket), rather than a 10A domestic socket.

(Detailed: 24kWh leaf has 21.3kWh usable. Derate to 93% because of battery health 21.3*.93 = 19.8kWh. Wall chargers without plug temperature monitoring in NZ are 8A, 230V. 8*230 = 1.84kW. Charger effichency ~ 0.9, 1.8*0.9 = 1.66kW. 19.8/1.66 = 11.92 Hours).

Apparently the NZ owner drove it to work on an 80km round trip and couldn’t charge at work so found the range anxiety too much.

Would have been great fuel savings if they could have made it work with that sort of mileage. Frankly I am surprised they didn't.

My 2014 has a 75% health battery (80,000km and over 1100 quick charges), can get 110+ Km out of it driving gently, and not using aircon, or about 100km driving normally.

With the higher health battery, if you leave on 100%, you should be able to drive 80km normally and still have 30% + or so in the battery. Perhaps they hard a demanding route (very hilly), an inefficient driving style, or just wanted more than 30% in reserve for detours etc.

First low battery warning goes off at 22% which is a bit disconcerting the first few times.

My turn to chime in!

I have a 2014 24X with 80%~ SOH.

I also have an 86km daily round-trip commute with no mid-way charging. Additionally I have a fairly aggressive driving style and get annoyed if I'm not at the speed limit.

In summer I make it home with about 30% remaining. In winter with the wipers going in a headwind and -3C in the morning I adjust my driving style to "fine I won't just sit in the fast lane" and make it home with about 10% remaining.

I've completed multiple Wellington-Palmy trips with a midway charge to 80% in Otaki.

It's a great little car and you have to realise that if you hit 0% you've still got several km in it at full speed and then several km in it at turtle speed. The density of chargers (even trickle chargers) is just too high to realistically get stranded anywhere. Additionally taking it from 100km/h to 90km/h for longer trips can seriously push its range out by 25%+. Push your car further and you'll get more comfortable in what it can do.

And most importantly enjoy :)

... while also not forgetting that 90kmh in a Leaf is probably closer to 81kmh in real terms, and doing around 80 on the open road is likely to frustrate other drivers...

(Every new Leaf owner should do some driving with a GPS or phone showing actual speed, so they get a sense of how much their car under-reports the speed; IME they're consistently one of the worst, with our Leaf being basically 10% out across the range.)
