Other body or interior problem on the 2009 Infiniti G37
When other body or interior problem gets reported
Owners of the 2009 Infiniti G37 report other body or interior problem at a median of 70,000 miles. A quarter of the reports come in before 45,000 miles and a quarter after 95,000 miles, from 9 reports that carried an odometer reading.
A part like this is normally expected to survive 88,000 miles. It is the 3rd most-reported problem on this model year.
The mileage distribution
The reported range runs from 35,000 miles at the tenth percentile to 125,000 miles at the ninetieth, a spread of 88,400 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.
11% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 34,400 miles | 45,588 miles | 71,000 miles | 96,000 miles | 122,800 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 $200–$2,000 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 2012, at a median of 10,000 miles, and latest on the 2009 at 70,000 miles.
By volume the 2010 carries the most reports, with 13; the 2009 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.

7.8.14 vehicle bought in to service dept to install navigation map update. Was told that navigation unit wasn't working. Infiniti ordered refurbished unit. 7.16.14 noticed gash in dashboard next to vent where they had to remove to be able to install new navigation unit. I have extended warranty for 2 more years. 7.23.14 brought car in to show the gash in the dashboard next to the AC vent after the navigation unit was installed. [xxx] the service manager looked at the gash and also discovered the melting dashboard affect near the window. He said he would order new dashboard and call me when it arrived to install. 8.12.14 called [xxx] 3 times as I did not hear back from him about the arrival of the new dashboard. Finally spoke with him and he said that he wanted to try and repair it before replacing it. That was unacceptable to me. I researched melting dashboard and discovered this is an issue with infiniti's and other vehicles. I placed a call to corporate infiniti and left message for [xxx] to discuss this issue and see what to do about getting a new dashboard as that is what the service manager notated on his form on 7.23.14…

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 other body or interior problem happen on the 2009 Infiniti G37?
Across 9 owner reports that included an odometer reading, half were filed by 70,000 miles. A quarter were filed before 45,000 miles and a quarter after 95,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other body or interior problem on the 2009 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.
