Defective battery pack
2018 SL, built 08/2018 in USA.
A few months ago the car started showing a noticeable range decrease.
When the car is charged to 100%, the dash shows a range of 241km (150miles) and the range decreases steadily till just below 80%. Below 80%, the range starts decreasing rapidly, at about triple the rate of when the battery is fully charged. Basically, same distance driven (40km) from 100% to 80% takes the battery from 80% to 25%. The overall range of the car is just over 100km (63 miles) which is way below the specs, even when taking into account the winter weather which has been mild this year.
Recently got myself a LS pro, which shows a "weak cell: 24" with a 268mV difference when fully charged (SOC 94.2%). At 20% on the dash LS SOC is at 51% and the difference for the weak cell is 110mV.
The dealership is sympathetic but told me that the Nissan corporate technicians who they have been consulting with consider the imbalance in cell voltage to be within tolerance and will not service the battery without a trouble code. They suggested reprogramming which hasn't made much of a difference for the overall range.
AHr=107.13, SOH=92.80%, Hx=111.46%
Odometer 29,032km (18,040 miles).

Has this been fully addressed yet?

Not fixed yet. The dealership reprogrammed the car. That of course didn't fix anything. I'm dropping off the car at the dealership again today for a few days so that they can drive it and observe the pathetic range for themselves. If this doesn't result in a warranty fix I am going to pursue a legal action against Nissan Canada.

My 2019 is less than 90 days old with almost 2,000 miles on it. I've been hearing a faint clunk every once in a while. I thought it was coming from the front passenger area. A quick inspection of the suspension with the wheel off shows nothing obvious. I have yet to be able to reproduce the issue consistently. I'll try hitting bumps while turning to see if it's similar to what jdcbomb has posted.

The charging port door froze closed once. A subsequent treatment of the gasket material with Krytox seems to have helped. My car gets washed as soon as possible after a snowstorm, so I definitely get water all over the place.

No other issues worth bringing up. I really like the car. Better than my 2015.

I took my Leaf in for the clunk and I don't know if it's been resolved or not. The dealership's response was that the lug nuts weren't tight enough. The service writer gave me a TSB printout showing that the lug nuts need to be at 83 ft/lbs. That torque setting is exactly what the hard copy owner's manual calls for. I used a torque wrench when mounting my winter wheels and I used the 83 ft/lbs. If the clunk is really gone then A) why wasn't it present on all four wheels, B) I need to calibrate my torque wrench, C) next time I'll just use 90.

UPDATE: I drove on some rough dirt roads at low speed. The clunk is NOT gone.

I heard some funny clunks from my left front suspension going over bumps, too, right before it failed yesterday: https://mynissanleaf.com/viewtopic.php?p=579988#p579988

Some people have remarked that a certain axle bearing or bushing needs to be tightened periodically to remedy this issue.

This issue, is not a "defect". Needing a repair is not an overall "defect" of the entire population of cars.

It is an older car as i remember. You should address the problem as discussed in the other topic you created.

I made that post before I actually determined what had failed, though I agree. The issue I was referring to is a separate matter: viewtopic.php?t=26079

About a month ago after the car has hardly been used and charged due to the covid 19 lockdowns I finally got the anticipated battery warning messages and the car went into a turtle mode. The dealership dropped the pack and manually tested each module. They found 2 modules with a lower current. They replaced those modules under warranty.

Not fixed yet. The dealership reprogrammed the car. That of course didn't fix anything. I'm dropping off the car at the dealership again today for a few days so that they can drive it and observe the pathetic range for themselves. If this doesn't result in a warranty fix I am going to pursue a legal action against Nissan Canada.

the only issue with my 2019 SL Plus is the high speed mode for the windshield wipers has never worked....low speeds ok....waiting for my annual battery check to get it fixed.

My car's 'Automatic Recirculate' feature just stopped working. The light flashes twice with the button press/hold, but then it goes right back to Recirculate.

You are not in any defrost modes, correct?
