2015 Nissan Leaf at 30,000 miles
You did not give a mileage, so this uses 30,000 — the median reported failure mileage for this model year, which is a rough stand-in for “a typical example of this car”. Put your real reading in the box below for an answer about your car.
At 30,000 miles on this car
At 30,000 miles on a 2015 Nissan Leaf, 13 of the failure modes other owners have reported already have their median report at or below your reading, and 1 more fall inside the window where they are usually reported. The heaviest of the ones already due is loss of braking.
Already past the median 13
Half of all reports of these failures came in at or below where your car is now.
- Loss of braking 11k
- Other electrical problem 18k
- Other speed control problem 6k
- Other engine problem 5k
- Seat belt or retractor failure 9k
- Other fuel system problem 20k
- Other wheel or tire problem 14k
- Other driver assistance problem 24k
- Control module (ECM/PCM/BCM) failure 8k
- Airbag failed to deploy in a crash 25k
- Airbag warning light or occupant sensor fault 6k
- Airbag inflator rupture 12k
1 more.

Your reading falls inside the middle half of reports for these.

Reported further down the road than where you are.
- Master cylinder or brake booster failure 34k
- Software fault or failed update 41k
- Parking brake failure 46k
- ABS module or sensor failure 55k
- No-start or intermittent start failure 60k
- Other powertrain problem 119k
Timing unknown 8
Reported, but too few owners gave an odometer reading to place them.
- Backup camera failure 2×
- Excessive oil consumption 1×
- Misfire or rough idle 1×
- Headlight failure or clouding 1×
- Tail light, brake light or signal failure 1×
- Other steering problem 1×
- Other seat belt problem 1×
- Other lighting problem 1×
Why the list is generic until you type a number
Every figure below is a comparison against your odometer, so with no reading given the page has to pick one: 30,000 miles, roughly what a 2015 car covers at 12,000 miles a year. A reading 30,000 miles either side of that moves failures between the columns, which is the difference between a useful list and a generic one.
Already inside the reported range
13 failure modes on the 2015 Nissan Leaf have a median reported mileage at or below 30,000: loss of braking (median 10,000 miles, 22 reports), other electrical problem (median 20,000 miles, 8 reports), other speed control problem (median 5,000 miles, 7 reports), other engine problem (median 5,000 miles, 3 reports), seat belt or retractor failure (median 10,000 miles, 2 reports) and other fuel system problem (median 20,000 miles, 2 reports).
These are the ones worth mentioning to a mechanic by name at the next service. Being past a median is not being overdue — it means the reports cluster below where you are now, so if the failure was going to be typical, it would already have happened.
The window you are in now
1 further mode is reported in a band that includes 30,000 miles: other brake problem (17k to 37,500 miles). These are the ones to watch on this car over the next few thousand miles.
A window here is the 25th to 75th percentile of reported mileages, so it holds the middle half of the reports and excludes the tails on both sides.
Still ahead of you
6 further modes sit above your reading, the nearest being master cylinder or brake booster failure at a median of 35,000 miles. On a car you intend to keep, these are the ones that decide whether it is worth keeping.
What this list is not
It is a reading of what owners of other 2015 Nissan Leafs reported, and at what odometer reading they reported it. It is not a maintenance schedule, not a diagnosis, and not a prediction about this car: two identical cars with different service histories are not the same car.
Complaints are filed voluntarily, mileages are typed in by owners and cluster on round numbers, and a failure mode with few reports has a wide window even when the median looks precise. Modes with fewer than 8 dated reports are shown without percentiles for that reason.
Where 30,000 miles falls on the curve
The three columns above sort the failure modes one by one. This is the same evidence in aggregate: every dated report on this model year, stacked up in the order the odometer readings arrived. The dashed line marked you is where your car sits. How much of the line is to the left of that mark is how much of this model year's reported trouble is, on the evidence, already behind you.
About 49% of the dated reports on this model year had already been filed by 30,000 miles. That is the share of the problems that show up in this record, not of the problems this car will have.
- Line share of reports filed by that mileage
- Dashed the mileages called out above
A steep early climb means a car whose reports cluster young, which is the pattern of a defect rather than of wear. A line that only gets going past six figures is the opposite. Neither shape says anything about the specific car in your driveway, and a curve built from a few dozen readings can be moved by one owner with a talkative afternoon.

Questions this page answers
What should I expect at 30,000 miles on a 2015 Nissan Leaf?
13 of the failure modes owners have reported on the 2015 Nissan Leaf have a median report at or below 30,000 miles, and 1 more fall inside the mileage window where they are usually reported. That is a watch list drawn from other owners, not a prediction about this car.
How to use the three columns. The left column is the list to hand a mechanic before you buy, and to check the service history for if you already own the car. The middle column is what to budget for this year. The right column is not a reprieve — it is a reminder that a used car has a bill schedule, and this is roughly where it falls. All of it is drawn from 144 owner complaints about this exact model year, not from a maintenance manual. How the percentiles are computed.
