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.

Clunking noise is likely an ongoing TSB to lube front end parts. Take it in. It is quite disappointing that this issue still shows up in such a new car. Was hoping the manufacturing process would have been changed by now. My 40 kwh had the same issue but did not start until about 5-6 months in. So far my E Plus has not but its just a month (of very light driving) on the road so far.
 
Update on the 18 MY SL: Dealership informed me they are flying in a senior regional Nissan tech next week to listen for himself the "tocking / knocking" sound coming from the left side. Existing TSBs, loose nuts, axles, ruled out by local and regional techs as root cause. Gonna be interesting. Still racking up miles on an otherwise great car (now nearing 8,500 miles 6 months into ownership of this unit).

Update on my other 18 MY SL that has a different sound emanating from the same area under the same driving conditions (left u-turn or sharp left turn).

Nissan manufacturing still determining what could be causing the "tock" sound to occur. The entire left axle was replaced but it didn't really do much. Regional Nissan tech is mystified and I find it fascinating that I have presented them with two LEAFs with frame sounds that take months to resolve. Customer service at the dealer is very good.

Good thing is they've ruled out it's a safety issue so I've been able to drive this vehicle normally without having to use a ICE loaner.

FINALLY: After 2 weeks of testing and investigating by a combined team at the collision center and suspension specialists, it was determined that a combination of the motor mount + crossbar (non-critical) interacting with the chassis was causing the noise. The components were replaced / tightened and it appears the bolts for the crossbars were just a quarter turn too loose, causing the play with the chassis. It took so long, and was such a unique issue, that the main tech lead at the collision center said he lost sleep over racking his mind on what could be causing it. They even rolled up the carpet, took out the front seat, and sat in a lawn chair in the vehicle to nail down the source. I miss this car and just glad I will be getting it back, but appreciate that Nissan / Gerber took the time and effort to solve the issue once and for all. Now I get to have them look at an eerily similar but different sounding issue emanating from the steering column on my other 18 MY LEAF! :D

2 weeks later after the dealer did further testing of the left front creaking and confirmed the location of the sound is coming from the chassis. My vehicle then was transported to Nissan's designated collision repair center (Gerber) for dis-assembly of the entire left/under sides to get deep into the frame. It took several days but I believe they finally found a bad weld somewhere in there. I expect to get a final report and my LEAF back in the next few days. Free rental vehicle started off as a Frontier, which then they swapped to a 2019 Altima with PP. Good service at this dealer.
 
Reading through this I’ve figured out one thing, I need to go to a new dealership. For my front end noise the Tech rode in the car and insisted he heard nothing. For the backup camera ( poor video quality) he told me right off the bat there was nothing he could do. Looks like for many of you here your dealerships looked at your cars and attempted fixes. Moral of the story, don’t go the City Nissan in Port Chester in NY.

I'm curious what comes of this. I have also experienced a strange sound when turning left into driveways or shopping centers. It is almost like a clunk and grind type of sound that I can feel vibrating in the chassis. It doesn't happen all the time but it is loud enough that my wife has noticed it when it does. I haven't cared enough to bring it in for service on this as I figured it would be hard to reproduce and I really don't want to deal with the downtime.

For what it’s worth, mine also does this. It doesn’t seem too alarming, though it is disappointing in a brand new car. I’ve been meaning to take it in.
 
Well I guess I should be glad I'm not the only one experience mysterious sounds when turning the vehicle to the left. Please PM me if you would like for me to post a recording of "knocking" for anyone here to listen as the sound is very obvious, but not loud, while also consistent everytime I make a u-turn to the left. It's not intermittent or hard to hear.

As for downtime, please do take it in, and ask that a Nissan tech sits with you, and reproduce the sound so there is verification it exists. NIssan should NOT prevent you from taking the vehicle back home while they "move the issue" up their chain. Hopefully, this data can result in a TSB that will make this fix much faster.

Note that my 18 MY SV was a different issue, which was a creaking from the cross bar bolts.

Definitely something wrong. My 2018 did it always in the same spot (took a year to develop) but my E Plus doesn't do it. On the last several weeks before trading up, I even "babied" the turn and still heard the sound over half the time. Will be interested to see if my E Plus develops it over time but I have literally been flying thru the turn testing it and so far it hasn't made a sound.
 
I honestly cannot tell if you're being sarcastic? Will you be taking it in to report a "too much range" issue?

Something is wrong with my battery. I am still getting 240 plus mile range in late December per charge, instead of the 215.

It helps it’s 55-60 in Chicago this week.
 
Yep, just having a little fun. Winter range on the car when it’s actually been cold has been pretty good so far. I tend to almost never use the heat, where my Wife runs it as soon as it drops below 40.

Heat is a factor but precip is what gets you. I also push 250 miles at this time of year when the weather is mild but add some rain and I am seeing as low as 200 miles. The other day, I was averaging 195 miles on half my trip (temp in low 40's, dry pavement, speed 65-80 mph) and 205 on the 2nd half (temp in low to mid 30's, rain heavy at times, standing water on road, speed 45-55 mph)

Used heat very little on the drive. Defrost a bit but mostly just seat heaters, steering wheel heater and windshield brush.

"... precip is what gets you." I have noticed this also, rain really reduces range. Just the car tires shoving all that water out of the way I guess, plus the tiny amount of power used by the wipers.... Both of my Leafs have had Ecopia tires, Michelin might be different?

Marginally if any. Rain is the great equalizer. Gas or electric; it doesn't matter. Efficiency takes a dive on everything.
 
2018 Leaf SL
Mfgtr date : 5/18
Purchased new 6/19 with 60 miles on it.

At 6,600 miles Dec/19, received red exclamation point triangle with red battery icon
“Warning
Service 12V charge system
Apply parking brake”

Nissan dealer service diagnosed, removed and replaced:

Power Delivery Module

We have been experiencing the “tock” sound when accelerating from a stop and when decelerating (both in e-pedal mode) only for the last two weeks or so. After the PDM replacement, the “”tock” sound has not changed. The 12V battery is charging and seems to still be healthy at a measured +18V after the DC-DC charger clicks off.
 
LeftieBiker said:
18 volts is very high for a 12 volt battery. It should be more like 14-15 volts after charging.

Agreed. I would think that much would cook a wet cell battery. Even a desulfation charge using my battery tender wouldn't go that high.
 
Update: The 18 SL has been back at the Nissan (Raleigh, NC) where instead of flying out a manufacturing engineer, they apparently heard the recordings, read the maintenance notes and actions taken before and have recommended to begin replacing specific parts, with the regional tech leading the analysis. Each part will be replaced in a sequence as the "most" likely culprit, then proceeding to the next possible part. (wheel bearings first, then others, then even the reduction gear)Again, this noise has nothing to do with any previous known TSBs / recalls, as this is clearly a mechanical issue when turning a sharp left turn, sounding like a grandfather clock knocking sound. This entire process could take a week or more. ICE as a loaner will be provided.

I have a clock issue. Since I got my E Plus, the clock has drifted. No more than a minute or so. I have adjusted it twice. This seems inconsequential, but realize my 4 previous LEAFs was set once and forget it.

So I get up the other day and the clock is FORTY MINUTES off!

I let it go all day but finally caved and reset it. In other news; Despite excessive speed, below freezing temperatures, rain, and a lot of defrost; I am still estimating over 200 miles of range. Not too shabby for Winter :)
 
Yesterday: 255 miles round trip, one QC to 80%, 3.4 M/KWH according to the meter (which would have netted about 207 miles), studded tires. First half of trip used 63% of charge, return used 62%, or about 193 miles full charge, or about 93% of what the meter was telling me. Used heat, - so it seems like the heat used about 7% of the available energy (and reduced the theoretical M/KWH range by that amount-my assumption is that the M/KWH meter can not measure heat use).
