Airbag warning light or occupant sensor fault on the 2008 Nissan Altima
1 crash 1 of the 70 reports for this failure mention a crash, a fire, an injury or a death. Those are the owner's words on the complaint form, not a verified finding, and one report can mention more than one.
When airbag warning light or occupant sensor fault gets reported
Owners of the 2008 Nissan Altima report airbag warning light or occupant sensor fault at a median of 72,500 miles. A quarter of the reports come in before 37,500 miles and a quarter after 127,500 miles, from 46 reports that carried an odometer reading.
A part like this is normally expected to survive 85,000 miles. It is the 3rd most-reported problem on this model year.
The mileage distribution
The reported range runs from 10,000 miles at the tenth percentile to 160,000 miles at the ninetieth, a spread of 150,000 miles across the middle 80% of reports.
When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.
24% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 9,000 miles | 36,625 miles | 71,733 miles | 127,250 miles | 159,000 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–$1,600 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 18 model years of this car. It shows up earliest on the 2006, at a median of 300 miles, and latest on the 2004 at 130,000 miles.
By volume the 2013 carries the most reports, with 259; the 2008 has 70. 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.
Driver's seat on '08 nissan altima moves side to side as you go around turns; very disconcerting. First response from dealership was "we can not replicate, and this is the first one we've heard of". Next visit I was told "nissan is aware of the problem, and should have a fix in 30 days or so". That was 45 days ago. 2nd problem, my passenger airbag light stays on a lot of the time my wife is seated in the seat. She's about 150 pounds, so there should not be a weight problem. Had it in twice for this, and another "can not replicate". I'm concerned that in the event of a collision, she will have no air bag protection. *tr

Drivers seat squirms moves and is not rigid. Dealership says they can not replicate the problem. Every time I turn the seat makes noise and sounds squirms like its not properly secure. The passenger airbag light also comes on when a fully grown adult is sitting in it. This happens randomly on an average of 4-5 times monthly. When the airbag light comes on the passenger airbag is deactivated not protecting the individual. There is also an issue with the brakes when pressed sometimes the brakes in the front do not grab properly and they grind badly causing the car not to stop as well . The dealership says can not replicate but stated they are aware of these problems and that nissan may issue a recall. For the time being the car is unsafe and nothing is being done about it. *tr

How far this goes
Complaints are voluntary, so 70 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.

How common is airbag warning light or occupant sensor fault on the 2008 Nissan Altima?

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.
