Unclassified problem on the 2012 Infiniti G37
1 crash 1 of the 24 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.
Only 11 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When unclassified problem gets reported
Owners of the 2012 Infiniti G37 report unclassified problem at a median of 55,000 miles. A quarter of the reports come in before 35,000 miles and a quarter after 75,000 miles, from 11 reports that carried an odometer reading.
It is the 23rd most-reported problem on this model year.
The mileage distribution
The reported range runs from 15,000 miles at the tenth percentile to 80,000 miles at the ninetieth, a spread of 64,000 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.
27% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 16,000 miles | 35,669 miles | 55,000 miles | 72,500 miles | 80,000 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.
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 45,000 miles, and latest on the 2008 at 95,000 miles.
By volume the 2009 carries the most reports, with 59; the 2012 has 24. 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 2012 infiniti g37x. The contact stated that the passenger side air bag indicator continuously illuminated as being off even though the passenger seat was occupied. The failure has occurred for two years. The vehicle was taken to the dealer who stated that there was a flaw in the sensor. The vehicle has not been repaired. The manufacturer was notified of the defect. The approximate failure mileage was 16,000. ....updated 07/23/14 *bf the consumer was informed that if a person weighed less than 110 lbs the air bag would not deploy. Updated 07/29/14
Tl* the contact owns a 2012 infiniti g37. After re-charging the vehicle's battery, the air bag sensor remained illuminated, which was a safety concern. The failure was not diagnosed or repaired. The local dealer (nissan of richmond in richmond, va) was notified of the failure. The manufacturer was not notified of the failure. The failure mileage was 59,000.
Bought this vehicle from crest infiniti with remainder of warranty which just ran out but as I went to sell the car privately the buyer was a car dealer in norman, ok who came down to plano, tx with trailer and cashier's check. After hooking up to diagnostic machine he refused to purchase due to an issue with the air bags and something about bypassed (report attached to complaint) air bags issue. This car was represented to me as never being in an accident and I never had one during the short time that I owned it. This is causing me a real problem as I have been diagnosed with terminal illness and need all the money I can muster through the sale of belongings with the auto being the durable good with the most value. They are now telling me that it really has very little value now because of this horrible air bag report. If I had bought it from a private party then caveat emptor would certainly apply but I bought it from a dealer with the remainder of warranty still applying to vehicle so 'as is' does not work here in my opinion.

How far this goes
This page is kept out of search results because 24 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 24 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 unclassified problem happen on the 2012 Infiniti G37?
Across 11 owner reports that included an odometer reading, half were filed by 55,000 miles. A quarter were filed before 35,000 miles and a quarter after 75,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is unclassified problem on the 2012 Infiniti G37?
24 reports have been filed with NHTSA, about 40 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.
