Is Nissan reliable?

When it starts to break

Each of the 58,621 Nissan complaints carries an incident date, so what follows is not the calendar year a report was filed but the age of the car when it failed. That age decides who pays: inside the warranty the manufacturer does, outside it you do. Half of everything reported on a Nissan arrives by 5 years, exactly the market median of 5.

On a Nissan 25% of reported failures land inside the first three years, so the other 75% arrive when the bill is yours. Which Nissan matters more than the badge: the NV draws 1.09 complaints per run and the Altima 9.3 — a 8.5-fold difference under one shield.

Nissan models ranked

Cleanest first, by complaints per production run — so a model that sold in millions is not punished for it. Across the 27 Nissan models on record the rate runs from 1.09 on the NV to 9.3 on the Altima.

Which Nissan years to avoid

Ranked by complaints per production run, so a year that simply sold well is not punished for it. Across 20 model years old enough to judge, the worst is 2013 at 12.1 per run and the cleanest 2020 at 2.5 — a 4.8-fold gap between two cars wearing the same badge.

The table stops at 2020 on purpose. Reports against a Nissan keep arriving for a decade after it is sold, so a newer year would top this ranking on age alone and tell you nothing about the car.

What actually fails on a Nissan

Systems owners reported to the regulator, ordered by how much of the Nissan complaint file each accounts for. The biggest single one is Power Train at 16% of everything filed, typically going wrong at 5.6 years old.

Take the top two to any pre-purchase inspection on a Nissan — a mechanic given named parts finds more than one told to look the car over.

How we measure it

Reliability scores usually arrive as a number out of five with no working shown. The Nissan figure on this page comes out of 58,621 individual reports, and here is exactly how they were turned into a rate — because two steps in that arithmetic are arguable and you should be able to argue with them.

Rate, not total. Volume alone would decide the ranking, so we divide by the number of production runs — the distinct first-eleven-character VIN prefixes on record. For Nissan that is 58,621 complaints spread over 10,319 runs — 5.68 per run against 3.73 for the market as a whole.

Age, not year. Incident date minus model year gives the age at failure, which is what the warranty question turns on. It is also why the Nissan year rankings above rest on 20 model years and stop at 2020: anything newer has not had time to break, and would win any comparison on age alone.

What this is not. Filing with a federal regulator takes effort, so what you see are faults someone judged serious — not scratched paint, not running costs, not how nice the car is to live with. Nor is a thin file a clean one — the Nissan NV sits on just 38 reports, which says how few reached US roads rather than how well they held up.
