Other electrical problem on the 2020 Nissan Leaf
When other electrical problem gets reported
Owners of the 2020 Nissan Leaf report other electrical problem at a median of 20,000 miles. A quarter of the reports come in before 10,000 miles and a quarter after 40,000 miles, from 9 reports that carried an odometer reading.
A part like this is normally expected to survive 85,000 miles. It is the 1st most-reported problem on this model year.
The mileage distribution
The reported range runs from 10,000 miles at the tenth percentile to 45,000 miles at the ninetieth, a spread of 35,400 miles across the middle 80% of reports.
Reports bunched into a band this tight usually mean the component has a life of its own: it goes at roughly the same mileage regardless of who owns it.
56% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 9,000 miles | 10,000 miles | 18,000 miles | 42,450 miles | 44,400 miles |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Putting it right typically runs $250–$2,000 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
The same failure on other years
The same failure is reported on 13 model years of this car. It shows up earliest on the 2013, at a median of 10,000 miles, and latest on the 2019 at 90,000 miles.
By volume the 2019 carries the most reports, with 141; the 2020 has 100. A mode that appears across most years of a model is usually a design choice rather than a bad batch.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
The contact owns a 2020 Nissan Leaf. The contact stated that the battery gauge was reading incorrectly. The contact stated that while doing a 70-mile roundtrip with 173 miles battery life, the battery gauge indicated the battery level was at 70 miles remaining. The vehicle was not diagnosed or repaired. The manufacturer was informed of failure and informed the contact that they were unable to assist. The failure mileage was approximately 10,000.

The contact owns a 2020 Nissan Leaf. The contact stated while driving approximately 50 MPH in the rain, a tree branch fell and struck the passenger’s side of the vehicle causing the air bags to deploy. The contact stated that he lost control of the vehicle when the air bags deployed. Additionally, the vehicle lost steering and braking functionality. There was an unknown warning light illuminated during the failure. The vehicle then lost electrical and motive power and rolled to a complete stop. There was no injury sustained. The vehicle was towed to an independent mechanic and was still awaiting the needed repairs. Neither a dealer nor the manufacturer had been contacted or notified of the failure. The approximate failure mileage was 12,000.

How far this goes
Complaints are voluntary, so 100 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.
Questions this page answers
At what mileage does other electrical problem happen on the 2020 Nissan Leaf?
Across 9 owner reports that included an odometer reading, half were filed by 20,000 miles. A quarter were filed before 10,000 miles and a quarter after 40,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other electrical problem on the 2020 Nissan Leaf?
100 reports have been filed with NHTSA, about 7.8 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
