Airbag warning light or occupant sensor fault on the 2009 Infiniti G37
1 crash 1 of the 49 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 2009 Infiniti G37 report airbag warning light or occupant sensor fault at a median of 72,500 miles. A quarter of the reports come in before 57,500 miles and a quarter after 87,500 miles, from 31 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 35,000 miles at the tenth percentile to 110,000 miles at the ninetieth, a spread of 72,940 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.
10% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 36,000 miles | 57,250 miles | 73,200 miles | 86,500 miles | 108,940 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 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 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.
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.
This is a frequent event that I just noticed a few months ago. When someone is in the front passenger seat of the vehicle, the airbag light comes on indicating that the passenger airbag is off. This occurs anytime a passenger sits in the front seat, regardless of weight or height. Today I also noticed that nissan has issued a recall for 1,053,479 vehicles globally for similar issues. However, my vehicle isn't included in this recall however there have been multiple reports of older model g35/g37 vehicles with the exact same issue. I think that my 2009 infiniti g37 should be included in this recall as well. I'm very concerned about this, because this is a huge safety issue! *tr
Pass air bag light came on as it is malfunctioning. It will not go off. Took it to dealer in greenville sc they said that the sensor in the seat is likely the problem but did not know for sure. Cost would be between $1500 and $3000 to replace. I called infinity service nationwide they said there is no recall. I see on this reporting website that this is happening to others and that it also was an issue with the 2008 g35 and that for the 2008 it is a recall issue. This should be a recall for the 2009 g37 also.
Just like the 2008, my 2009 g7 coupe passenger side airbag sensor is defective and no longer works. I called infiniti but was told that my 2009 did not qualify. They want over $4000 to replace the bottom cushion (without labor). $4000!!!! 2008 infiniti g37 air bags recall 08v521000. Occupant classification system (ocs) control units. A varistor in the ocs control unit located in the passenger seat cushion may have been manufactured out of specification. Under certain conditions, this could cause an interruption of signal between the ocs and the air bag control unit (acu).

How far this goes
Complaints are voluntary, so 49 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 2009 Infiniti G37?

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.
