Other engine problem on the 2009 Infiniti G37
1 crash 1 of the 16 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 other engine problem gets reported
Owners of the 2009 Infiniti G37 report other engine problem at a median of 65,000 miles. A quarter of the reports come in before 30,000 miles and a quarter after 115,000 miles, from 14 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 2nd most-reported problem on this model year.
The mileage distribution
The reported range runs from 5,000 miles at the tenth percentile to 155,000 miles at the ninetieth, a spread of 150,693 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.
36% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 6,607 miles | 28,153 miles | 65,000 miles | 114,750 miles | 157,300 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–$4,000 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 2010, at a median of 25,000 miles, and latest on the 2011 at 75,000 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.
Tl* the contact owns a 2009 infiniti g37. The contact stated that the vehicle stalled without warning while driving. The failure was experienced several times. The vehicle was towed to the dealer. A diagnostic test was performed, which located the failure at the engine. The dealer stated that the engine failed due to poor maintenance. The vehicle was not repaired. The manufacture denied assistance with the repair. The VIN was not available. The failure and current mileages were 27,000.
While stopping vehicle, braking became non-responsive and engine began racing. Vehicle was extremely difficult to stop completely. After taking foot off of brake pedal, vehicle lunged forward as if accelerator pedal was fully depressed. This has occurred on 12/9/12 , 12/10/12, 12/15/12. Infiniti has not corrected problem. This rapid acceleration / non-responsive braking has caused two (2) near miss accidents.
When engine is started it occasionally revs to 4000-5000 RPM and remains there for about 5-7 seconds before slowing down to a normal idle speed. The occurrences are becoming more frequent. When acting normally, the engine starts and revs to about 2000 RPM and then slows to idle speed in about 1-2 seconds. The danger of the high revs for 5-7 seconds is that if the driver is not fully aware of the engine's speed, he could shift the car into gear and the car would accelerate, perhaps hitting nearby cars, house, out the garage door, etc. I had such an incident and was barely able to hold the car in place with full force on the brakes. The dealer has stated that he is unaware of any service bulletins concerning this issue, but if I would bring it in, they would check the settings on the engine control. In my opinion, this is a very serious situation akin to the toyota unexpected acceleration problem and infinti needs to develop first an acknowledgment of the problem and then a solution. *tr

How far this goes
Complaints are voluntary, so 16 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.

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.
