Other speed control problem on the 2011 Infiniti G37
4 crashes 1 injury 5 of the 8 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 speed control problem gets reported
Owners of the 2011 Infiniti G37 report other speed control problem at a median of 10,000 miles. A quarter of the reports come in before 1,800 miles and a quarter after 25,000 miles, from 8 reports that carried an odometer reading.
A part like this is normally expected to survive 78,000 miles. It is the 4th most-reported problem on this model year.
The mileage distribution
The reported range runs from 900 miles at the tenth percentile to 50,000 miles at the ninetieth, a spread of 48,375 miles across the middle 80% of reports.
Reports bunched into a band this tight usually mean the component has a life of its own: it goes at roughly the same mileage regardless of who owns it.
75% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 925 miles | 1,750 miles | 9,528 miles | 25,000 miles | 49,300 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, 4 a crash and 1 an injury are 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 $250–$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.
This mode is classified as critical, which means a failure can leave the car unable to stop, steer, or stay out of the way of traffic. It is weighted accordingly in the risk score.
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 55,000 miles.
By volume the 2009 carries the most reports, with 9; the 2011 has 8. 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 2011 infiniti g37 coupe. The contact stated that at 2 MPH, he was attempting to park the vehicle in a residential garage when the vehicle abnormally accelerated and crashed. The front bumper was slightly damaged but the contact was not injured. The vehicle was taken to the dealer who contacted the manufacturer and a representative was sent to inspect the vehicle. There were no failures found within the vehicle. The contact stated that he had experienced the failure twice prior to the crash. The dealer also inspected the vehicle but could find no failures. The failure mileage was 750.
Tl* the contact owns a 2011 infiniti g37sx coupe. While driving approximately 20 MPH, the contact approached a stop signal, engaged the brake pedal and the vehicle surged forward with an increase in the rpms. The identical failure occurred five times. The vehicle was taken to an authorized dealer on six occasions regarding the unintended acceleration. The technician was unable to duplicate the failure or detect a trouble code during the diagnostic test; however, the electronic module was reprogrammed. The failure continued to occur. The manufacturer was notified of the failure. The approximate failure mileage was 1,000.
While pulling into a parking place in a shopping center, with my right foot on the brake and the car stopped, the motor raced and the back tires spun at high speed, I turned the car off and had it towed to the dealer where it is now. This is the second time this has happened, I drove the car after the first event because I was not sure what happened. I believe this is very dangerous. I find online this has happened to other infinity owners. *tr

How far this goes
Complaints are voluntary, so 8 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 speed control problem happen on the 2011 Infiniti G37?
Across 8 owner reports that included an odometer reading, half were filed by 10,000 miles. A quarter were filed before 1,800 miles and a quarter after 25,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other speed control problem on the 2011 Infiniti G37?
8 reports have been filed with NHTSA, about 13 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.
