Airbag warning light or occupant sensor fault on the 2013 Infiniti G37
When airbag warning light or occupant sensor fault gets reported
Owners of the 2013 Infiniti G37 report airbag warning light or occupant sensor fault at a median of 35,000 miles. A quarter of the reports come in before 900 miles and a quarter after 65,000 miles, from 9 reports that carried an odometer reading.
A part like this is normally expected to survive 85,000 miles. It is the 1st most-reported problem on this model year.
The mileage distribution
The reported range runs from 700 miles at the tenth percentile to 70,000 miles at the ninetieth, a spread of 67,066 miles across the middle 80% of reports.
A spread this wide points at use rather than design. Towing, climate, service history and city mileage all move a failure like this, so the median is a weak guide to any individual car.
56% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 660 miles | 892 miles | 34,000 miles | 66,000 miles | 67,726 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
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 6 model years of this car. It shows up earliest on the 2013, at a median of 35,000 miles, and latest on the 2009 at 72,500 miles.
By volume the 2009 carries the most reports, with 49; the 2013 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 2013 infiniti g37. The contact stated that the passenger side air bag light was continuously illuminated when a passenger of one hundred pounds or lighter sat in the passenger seat. The dealer stated that the vehicle was working up to specifications. The manufacturer was not notified of the defect. The approximate failure mileage was 700.
Passenger air bag light would light up (meaning air bag will not deploy) when my wife (117 lbs) was seated on the front passenger seat. This was also happening on my 2010 nissan frontier pro 4x truck with leather seats. Nissan dealer could not fix it. They were blaming my wife. This is a safety issue! Please help. Thank you! *tr
While driving with a full size adult in the passenger seat, the passenger air bag light was illuminated, which indicates that the passenger air bag is off. This has continued to occur at various speeds including while idling. The car has been returned to the infiniti dealer four times. The infiniti service writer, manager and technician saw the passenger air bag light on. An infiniti engineer checked the car on 9/10/2014. His report stated that the car is operating according to specification. They see no need to pursue this problem any further while this problem continues, jeopardizing the passenger's safety. *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 airbag warning light or occupant sensor fault happen on the 2013 Infiniti G37?
Across 9 owner reports that included an odometer reading, half were filed by 35,000 miles. A quarter were filed before 900 miles and a quarter after 65,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is airbag warning light or occupant sensor fault on the 2013 Infiniti G37?
11 reports have been filed with NHTSA, about 18 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.
