Drove my 2018 for a year. The only issue was a steering wheel vibration at 65 mph. Dealer identified a bad tire when they road force balanced uf. Replaced the Michelin tire and vibration was gone.

No other issues at all.

Update: After the dealer inspected and tested the brake pedal it was determined it was normal. It was simply the solenoid sensor that does the e-pedal braking. The sound is generally only audible when the audio system is off, windows closed, and A/C on low. Must not have heard it previously as I usually had music playing at medium level. It was definitely not the lug nuts as they rotated my tires on this same visit.

I actually test drove a PLUS unit on that same visit, and heard the same sound.

Warmer weather did not stop the click. It doesn't seem to affect the operation of the pedal, but the sound gets annoying especially how quiet it is inside. I'll get it examine during a visit to the dealer in a couple months. No other issues observed.

2018 SL Manuf: 2018.08

Not sure if this can be classified as a defect or just plain bizarre:

Driving at about 72 mph on NC 540 toll road with e-Pedal on, ProPilot on and fully engaged (lane + distance). Outside temperature about 80 F. Time around 19:40 EDT.

Passed under electronic toll both at 72 mph. Have driven under this booth at least 20 times without issue. Within a second or two, multiple warning lights and beeps + PP disengages + e-Pedal shuts off + VDC shuts off. (Warnings: e-Pedal System Malfunction)

Arrived home with several warning indicators. Shut off vehicle. Turned it back on. Some indicators gone. All come back when e-Pedal or PP are turned on.

Took into dealer first thing. After an hour or diagnostics, they confirmed no issue after re-programming / resetting the codes. Unrelated bonding plate also replaced (as part of recall).

What the heck happened? Anyone else?

Didn't North Carolina recently implement a toll road anti-speeding campaign, that cars that went through a toll booth exceeding the posted limit were hit with an EMI pulse which temporarily disabled the vehicle to slow it down?

Sounds like an urban legend, or distortion of something else. An actual EMP would disable cars by destroying their chips. A pulse too weak to do that but still able to slow them? Maybe, but that would be lawsuit bait. Not that I have much sympathy for speeders...

Although it's possible I believe the theory of an EMI causing this extremely unlikely. That would probably break multiple FCC / local laws on wireless transmissions, and would be all over the news / forums every day.

The going theory is that the wireless readers when scanning for my toll RFID somehow reflected directly into the radar sensor causing the system to freeze up. The service manager was surprised too, as he also thought at first it was a bad front sensor. He did say he saw this happen to another Nissan PP equipped vehicle before under the similar conditions.

I do wonder if It means the radar / camera and other sensors need to be recalibrated shielded to not accept this kind of interference.

Any 2018 LEAF's having problem with A/C blowing warm air intermittently, and having to wait or re-start car to get blowing cold again?

Possibly mine. I'm honestly not sure if it's just a cool cabin from a cool garage, or if sometimes when I first start driving in hot weather I get some inappropriately warm air for a few minutes.

2018 SL, the automatic emergency brake warning light kept turning on. Took it into the dealership, and they are waiting on a part. They said it was on back order due to this being a common issue, so I'd be interested to see if anyone else is in the same boat.

It sounded like the forward facing radar (in the front bumper) shorted out due to moisture getting in, but I might not have all of the info yet.

I'll edit this post with any updates, hopefully it won't take too long to get the part...
Not a Leaf but I had a rental '18 Sentra when I was in upstate NY just within the past 2 weeks. The Enterprise rent a car person who picked me up in it and the car got some error about the front radar or collision warning system, most likely the one at https://www.digitaltrends.com/cars/faul ... ng-system/. The worker said ugh and claimed it was a bug on the sensor.

Well, whatever. I took that car as a rental and kept getting that error but then it might go away for 20 minutes and then come back. I put over 200 miles on that car in short order and it was frankly annoying as it kept going away for awhile then coming back.

When I dropped off the car, another worker dropped me back off at my hotel in the same car, he said "all" their Sentras have that problem. He claimed that one he drove suddenly slammed on the brakes for no reason due to the above sensor prob, which to him was dangerous. Sounded like Enterprise wasn't having great luck w/getting their Sentras fixed for this.

OTOH, the '19 Altima rental I had in AZ and put over 450 miles on also had such a warning system standard and I never had this problem.

This is a common issue with the 2018 Leaf. Mine had it, but it seems to have gone away on its own, after showing up quite a few times after I drove on dusty, freshly-grooved pavement last Fall.
