When other brake problem gets reported

Owners of the 2014 Nissan Leaf report other brake problem at a median of 35,000 miles. A quarter of the reports come in before 10,000 miles and a quarter after 45,000 miles, from 10 reports that carried an odometer reading.

A part like this is normally expected to survive 88,000 miles. It is the 1st most-reported problem on this model year.

The mileage distribution

The reported range runs from 5,000 miles at the tenth percentile to 45,000 miles at the ninetieth, a spread of 41,150 miles across the middle 80% of reports.

A window that narrow is the signature of a part that fails on its own schedule rather than on how the car is driven — which is usually a design or supplier problem rather than wear and tear.

50% of the dated reports were filed under 36,000 miles.

The whole distribution

Percentiles of the 10 odometer readings owners gave.
10th25thMedian 75th90th
6,160 miles 9,375 miles 33,500 miles 46,500 miles 47,310 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

Of these reports, 1 a crash is mentioned. Owners write their own complaints and the agency does not verify them, so read this as what the reports say happened rather than as a confirmed count.

Putting it right typically runs $300–$1,800 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 9 model years of this car. It shows up earliest on the 2011, at a median of 5,000 miles, and latest on the 2022 at 110,000 miles.

By volume the 2015 carries the most reports, with 42; the 2014 has 11. 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.

Tl*the contact owns a 2014 nissan leaf. The contact stated that while shifting from park to drive on an incline and the brake pedal depressed, the vehicle rolled down hill. The contact mentioned that the brake pedal hesitated to respond. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 6,400. The VIN was not available.

6,400 miles NHTSA complaint 1160060 filed 2015-02-24

Whenever outside temperatures are below +/- 38f, the regenerative brake system behaves very aggressively in the sense that the slightest use of the brakes results in a very jerky bevahiour of the car, braking very abruptly and hard. Usually, a second tap on the brake resolves the issue temporarily, but the symptom comes back soon after. This is not only an inconvenience, but also poses potential accidents if a car behind the leaf is not expecting a hard braking. Contacted the nissan dealer with the symptoms, reply was that this is not known to nissan.

4,000 miles NHTSA complaint 1160785 filed 2015-02-26

Nissan did not notify me of this recall of the leaf which was effective february 26, 2016. When I called nissan regarding their lack of notification on this issue, the company, moreover, did not acknowledge the recall citing a 'service notice' has been in effect since october 15, 2015 of which I also did not receive notification! Could you please follow up on this recall with nissan and inform me of their response. Thank you. *tr

How far this goes

Complaints are voluntary, so 11 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 brake problem happen on the 2014 Nissan Leaf?

Across 10 owner reports that included an odometer reading, half were filed by 35,000 miles. A quarter were filed before 10,000 miles and a quarter after 45,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.

How common is other brake problem on the 2014 Nissan Leaf?

11 reports have been filed with NHTSA, about 0.1 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.
