2023 Nissan Altima: what breaks, and at what mileage
What breaks on the 2023 Nissan Altima
On the 2023 Nissan Altima, the failure owners report most often is airbag failed to deploy in a crash, with 5 reports on file. Across every failure mode on this year, half the dated reports were filed before 35,000 miles. Overall it scores 66 out of 100, high risk for a 2023.
High risk for a 2023 — 198th riskiest of the 227 2023 vehicles we can rate. 40 owner reports; fleet size borrowed from other years of the same model.
What owners report breaking
Owners have reported 23 named failure modes on the 2023 Nissan Altima, and the three most-reported carry 28% of everything filed, which is an unusually even spread for one model year.
Airbag failed to deploy in a crash leads with 5 reports and about 0.1 per 1,000 vehicles.
Other electrical problem follows with 3 reports.
Other driver assistance problem follows with 3 reports.
By system, the reports fall mostly into airbag (6), electrical (5) and adas (5).
When these failures get reported
Too few of the reports on this year carry an odometer reading to describe the timing: 6 of them do. The mileages quoted elsewhere on this page come from the modes that have enough of them.

How reports accumulate
Every report with an odometer reading, cumulative, from 0 to 200,000 miles. A curve that climbs early is a car with early problems, whatever its total.

What happens when these parts fail
Across the named modes, 10 mention a crash, 1 a fire and 2 an injury. Those are the words owners used in their own complaints, and NHTSA does not verify them, but they are the closest thing in this data to a measure of what a failure actually did.
The average severity weight across every report on this year is 5.40, where a stalled engine or a failed airbag weighs many times more than a rattling trim panel, and a figure this high means the reports are dominated by failures with safety consequences rather than annoyances. The weighting is set out in full on the methodology page.
What the top failures cost to put right, as editorial estimates for an independent US shop rather than figures from NHTSA: airbag failed to deploy in a crash at $1,000–$5,000, other electrical problem at $250–$2,000, other driver assistance problem at $250–$1,800 and other visibility problem at $150–$1,400. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.
18% of the reports on this year sit in the engine, transmission, drivetrain or cooling systems — the four where a repair bill is usually four figures.

This year had no usable recall paperwork, so the fleet-size estimate is the median of other years of the same model. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.
How often, against how many were built
Scaled by an estimate of how many of these cars exist, the 2023 Nissan Altima draws about 1.0 per 1,000 vehicles, which puts it in the 74th percentile of complaint rates among 2023 vehicles we can rate.
That denominator is the weakest number on the page and it is fair to say so plainly. This year had no usable recall paperwork, so the fleet-size estimate is the median of other years of the same model.
The working figure is 38,177 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2023 vehicles, which is what the risk score uses, is far more robust than the rate itself.
How it ranks in the 2023 field
The score at the top of the page, placed among its peers. The zones are the same thresholds the scorer applies, read out of the scorer itself, so the picture and the band word cannot disagree.
Scores are ranked within the model year, never across years, because an older car has had longer to accumulate reports.

Better and worse years of the same car
High risk for a 2023 — 198th riskiest of the 227 2023 vehicles we can rate. Every score on this site is a rank inside its own model year, which is what makes a 2004 and a 2019 comparable at all.
Across the 29 model years of this car that carry enough reports to score, 2018 comes out best at 63 and 2024 worst at 83, with 2023 itself at 66.
If the model year is negotiable, 2018 scores lower than 2023 by a margin worth acting on. Same body, same engines, different luck — usually a supplier change or a mid-cycle fix, which the complaint data can show but never explain.
Within the 2019–2025 generation specifically, 2023 is the strongest year at 66 and 2024 the weakest at 83.
Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.
Shorter is better. Years with too few reports to score are shown without a bar rather than as a zero, because no data is not good news.
Within the 2019-2025 generation, 2023 Nissan Altima scores best at 66 and 2024 Nissan Altima worst at 83.
What this page cannot tell you
40 owner reports; fleet size borrowed from other years of the same model. Every count on this page is therefore a floor: it is the number of owners who went to the trouble of filing with a federal agency, which is a small and self-selected fraction of the owners who had the fault.
Of those 40 reports, 6 carried an odometer reading, so the mileages here describe 15% of the sample rather than all of it. Owners also round: readings pile up on multiples of ten thousand, which is why this site publishes "about 90,000 miles" and not "91,438".
Named failure modes come from matching phrases in the complaint text, so a badly worded complaint can land in the wrong bucket. The effect washes out across hundreds of reports and does not wash out across five.
And nothing here predicts what one car will do. These are other people's complaints, filed years apart, on cars maintained by strangers. Read the page as a map of where this model year has previously gone wrong, then have the specific car in front of you inspected.
Questions this page answers
What are the most common problems with the 2023 Nissan Altima?
The most-reported failures are airbag failed to deploy in a crash (5 reports, median 5,000 miles), other electrical problem (3 reports) and other driver assistance problem (3 reports). Counts come from owner complaints filed with NHTSA, which are voluntary, so they show what owners bothered to report rather than every fault that occurred.
Is the 2023 Nissan Altima reliable?
It scores 66 out of 100 on our risk index, which is high — 198th riskiest of the 227 2023 vehicles we can rate. The score is a comparison against other 2023 vehicles, not a prediction about any individual car, and it is built from complaint rates, severity and how early failures appear.
Which year of the Nissan Altima is best?
Within the 2019–2025 generation, 2023 scores best at 66 out of 100 and 2024 worst at 83. Same body, same engines, different luck.
Where this comes from. Every figure above is computed from NHTSA owner complaints and recall records for this exact make, model and year. Complaints are voluntary and self-selected, so treat counts as a floor. The methodology page writes out each formula, and the same numbers are available as JSON.
