2013 Infiniti G37: what breaks, and at what mileage
What breaks on the 2013 Infiniti G37
On the 2013 Infiniti G37, the failure owners report most often is airbag warning light or occupant sensor fault, and the reports cluster around 35,000 miles. Across every failure mode on this year, half the dated reports were filed before 40,000 miles. Overall it scores 74 out of 100, high risk for a 2013.
High risk for a 2013 — 91st riskiest of the 284 2013 vehicles we can rate. 84 owner reports; fleet size borrowed from other years of the same model.
What breaks on the 2013 Infiniti G37
Owners have reported 24 named failure modes on the 2013 Infiniti G37, and the three most-reported carry 26% of everything filed, which is an unusually even spread for one model year.
Airbag warning light or occupant sensor fault leads with 11 reports, about 18 per 1,000 vehicles and with the middle half of reports between 892 to 65,000 miles.
Other body or interior problem follows with 6 reports, median 40,000 miles.
Airbag failed to deploy in a crash follows with 5 reports, median 30,000 miles.
By system, the reports fall mostly into airbag (17), body (10) and electrical (8).
The mileage the reports cluster at
54 of the reports on the 2013 Infiniti G37 came with an odometer reading, and half of those were filed before 40,000 miles.
Cumulatively, 61% by 50,000 miles, 94% by 100,000 miles and 98% by 150,000 miles of the dated reports had been filed.
The busiest stretch is between 0 and 10,000 miles, which alone holds 24% of the dated reports.
43% of the dated reports were filed below 36,000 miles, which is early enough that a fair number of these cars were still under a factory warranty when the owner complained.

Severity, and what it costs
Across the named modes, 13 mention a crash and 6 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 4.95, 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 warning light or occupant sensor fault at $300–$1,600, other body or interior problem at $200–$2,000, airbag failed to deploy in a crash at $1,000–$5,000 and control module (ECM/PCM/BCM) failure at $700–$3,000. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.
8% 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 2013 Infiniti G37 draws about 141 per 1,000 vehicles, which puts it in the 98th percentile of complaint rates among 2013 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 596 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2013 vehicles, which is what the risk score uses, is far more robust than the rate itself.
What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The odometer reading is the one the owner gave.
Airbag warning light or occupant sensor fault
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
Other body or interior problem
I also owned a g35 2008 infiniti with the same problem..the doors lock and I can not get in or out. The lock actuators fail. The doors can not be opened mechanically or electrically. The doors were locked when I went in the gym for 1/2 hour and when I came out I could not enter the car the doors were loced and would not open. After a while I was able to get the back seat door open. I drove the car home and was unable to get out of the car . All doors locked. The only way out is through the window. This is a huge safety concern,
While pulling into a parking space and braking going 1 or 2 MPH the car surged forward with the engine revving loudly, causing the car to crash through a brick wall and into a restaurant ending in the car being totaled with over $15,000 of damage just to the car. The car only had 20,000 miles. A quick google search for "g37 surge while braking" results in numerous different accounts in which this has happened as well as on this website under infiniti g37.
Airbag failed to deploy in a crash
I was in a parking lot. I backed out when I started to shift into drive the car accelerated and started to spin in circles. The steering wheel locked. I was not in control of the car and nothing would worked in the car. I couldn't shift gears so I shoved it into park. The car finally stopped but not before it hit an island causing $7822 in damages to the rear of the car. The air bags did not deploy. I was quite shaken up but had no serious injury. A police report was filed. The manufacturer was contacted at the local and regional levels. They had someone look at the vehicle but after 7 weeks they still have not contacted me with their findings. I am not driving the vehicle and I have not had it repaired. I fear that if I have it repaired and I sell the vehicle, it is an unsafe car and someone else will get hurt. I have found several reports of similar occurrences on the internet.

How it ranks in the 2013 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.
- Left fewer and less serious reports
- Right more, or worse
- Marker this vehicle
Where 2013 sits in the model line
High risk for a 2013 — 91st riskiest of the 284 2013 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 6 model years of this car that carry enough reports to score, 2008 comes out best at 64 and 2012 worst at 76, with 2013 itself at 74.
If the model year is negotiable, 2008, 2009 and 2011 score lower than 2013 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 2007–2013 generation specifically, 2008 is the strongest year at 64 and 2012 the weakest at 76.
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 2007-2013 generation, 2008 Infiniti G37 scores best at 64 and 2012 Infiniti G37 worst at 76.
Where to spend the inspection money
The mileages below are where the first quarter of reports for each mode had already been filed, which makes them the point at which a fault is worth looking for rather than the point at which it happens: airbag warning light or occupant sensor fault from about 892.
On a 2013 Infiniti G37 with more miles than that on it, the useful question to put to a seller or a mechanic is whether airbag warning light or occupant sensor fault has been dealt with, and if so with what parts and at whose expense. A car that has already had the repair is in a different position from one that has not.
Treat it as where to point the inspection, not as a prediction. A well-maintained example can sail past every mileage on this page, and a neglected one can fail well before the first of them.
Where these figures stop being useful
84 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 84 reports, 54 carried an odometer reading, so the mileages here describe 64% 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".
The failure modes are assigned by software reading the owner's own words, which is accurate in bulk and wrong in individual cases. A mode with a handful of reports may contain a misfiled one.
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 2013 Infiniti G37?
The most-reported failures are airbag warning light or occupant sensor fault (11 reports, median 35,000 miles), other body or interior problem (6 reports, median 40,000 miles) and airbag failed to deploy in a crash (5 reports, median 30,000 miles). 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.
At what mileage do 2013 Infiniti G37 problems start?
Airbag warning light or occupant sensor fault is the earliest failure mode to show up, with a median reported mileage of 35,000 miles and a quarter of reports before 900 miles. Across all failure modes on this year, the median report sits at 40,000 miles.
Is the 2013 Infiniti G37 reliable?
It scores 74 out of 100 on our risk index, which is high — 91st riskiest of the 284 2013 vehicles we can rate. The score is a comparison against other 2013 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 Infiniti G37 is best?
Within the 2007–2013 generation, 2008 scores best at 64 out of 100 and 2012 worst at 76. 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.
