Other speed control problem on the 2010 Infiniti G37
3 crashes 3 of the 9 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 2010 Infiniti G37 report other speed control problem at a median of 20,000 miles. A quarter of the reports come in before 5,000 miles and a quarter after 45,000 miles, from 8 reports that carried an odometer reading.
A part like this is normally expected to survive 78,000 miles. It is the 3rd most-reported problem on this model year.
The mileage distribution
The reported range runs from 2,100 miles at the tenth percentile to 50,000 miles at the ninetieth, a spread of 46,373 miles across the middle 80% of reports.
A window that narrow is the signature of a part that fails on its own schedule rather than on how the car is driven — which is usually a design or supplier problem rather than wear and tear.
63% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 2,116 miles | 5,245 miles | 20,726 miles | 45,068 miles | 48,489 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, 3 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 $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 2010 has 9. 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.
I was driving along at approximately 35 MPH (speed limit) in the middle lane of a 3 lane road and approached a red light. I braked, but instead of the car slowing down, it started accelerating very fast. I pressed down on the brake as hard as I could but the car continued speeding up. There were cars on both sides of me so I hit a pickup truck in front of me - the air bags deployed on both my side and the passenger side where my son was sitting. My car hit the tow bar on the pickup truck and totally crumbled. Neither my son nor I were hurt because the air bags provided protection. The fellow in the pick up truck did not suffer any injuries at all. However, damages and repair to my auto cost my insurance company more than $19k. The car was returned to me after more than 9 weeks (5/20/11) in the shop. At the time the car was returned it had approximately 3020 miles. After a day or two, the car began to run very roughly when idling at lights. I telephoned the dealership and arranged to bring the car in for service on wednesday, 5/25/2011. On the way to the dealership, the car failed again except this time, I was halted at a red…
I started my car with my foot on the brake and it revved up to 4500 rpms. I took out my phone and had time to take two pictures of the meter. I turned the car off and it did it again, for a total of three times. The same thing had happened once earlier in the day. I also happens sporadically when I first start it in the morning. Sometimes I feel it is going to go throughout the garage wall. Fortunately to start it I must have my foot on the brake! *tr
The car has an erratic shifting of the 7-speed automatic transmission. In highway driving at lower speeds below 40 MPH due to slow traffic, the transmission shifts on occasion into a gear where the engine RPM drops and holds at 1000 - 1100. If you accelerate slowly the RPM's remain at about 1000 unless you actually push the pedal all the way down to the floor board. At this point if you try to accelerate and pick up speed there is a great hesitation. I now have 15,000 miles on this car and the dealership has told me in the past that it can not duplicate the problem. I have seen several complaints on the edmonds.com forum site that describe my car's problem and other drivers agree that this will cause an accident or possibly cost someone their life if this problem is not addressed. At one point the dealership told me that my car's on board computer is learning my style of driving habits and it will eventually be okay. I am seriously considering trading the car but in good conscience I am concerned about my legal obligation to divulge this problem to the next owner. This is a serious problem that needs to be investigated. *tt

How far this goes
Complaints are voluntary, so 9 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.

At what mileage does other speed control problem happen on the 2010 Infiniti G37?
Across 8 owner reports that included an odometer reading, half were filed by 20,000 miles. A quarter were filed before 5,000 miles and a quarter after 45,000 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 2010 Infiniti G37?
9 reports have been filed with NHTSA, about 15 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.
