Other brake problem on the 2009 Infiniti G37

1 crash 1 of the 4 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.

Only 4 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.

When other brake problem gets reported

There are 4 reports of other brake problem on the 2009 Infiniti G37, 4 with a mileage attached. That is too few to place the failure on the odometer with any confidence.

A part like this is normally expected to survive 88,000 miles. It is the 11th most-reported problem on this model year.

The whole distribution

Percentiles of the 4 odometer readings owners gave.
10th25thMedian 75th90th
— — 28,005 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–$1,800 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 3 model years of this car. It shows up earliest on the 2009, at a median of 30,000 miles, and latest on the 2011 at 70,000 miles.

By volume the 2008 carries the most reports, with 4; the 2009 has 4. 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.

Pulling into parking stall (brakes applied / traveling 5-10 MPH) the car lurched forward twice and stuck a parked full size truck. The car bounced backwards and lurched forward again and stuck the truck a second time and bounced backwards again. The ( off button) was able to be pushed at that time. The brake was fully applied the entire time. This has been the only occurrence. Infinity has not been able to duplicate problem and has downloaded the data base. The formal report will take approx. 4 weeks to complete. No parts have been replaced. Infinities consumer's affair has told us to pickup the vehicle and drive the vehicle despite no explanation or written proof the vehicle is safe to drive. The problem is related to either braking, acceleration or both. *tr

45,000 miles NHTSA complaint 818666 filed 2010-10-05

Vehicle vibrates when braking. Dealership found all four rotors out of round. Dealership also found rear rotors warped. Dealership cut front rotors and resurfaced rear rotors. *tr

10,426 miles NHTSA complaint 861306 filed 2011-06-12

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.

How far this goes

This page is kept out of search results because 4 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.

Complaints are voluntary, so 4 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 brake problem happen on the 2009 Infiniti G37?

Across 4 owner reports that included an odometer reading, half were filed by 30,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.

How common is other brake problem on the 2009 Infiniti G37?

4 reports have been filed with NHTSA, about 6.7 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.
