Other speed control problem on the 2009 Chevrolet Equinox
When other speed control problem gets reported
Owners of the 2009 Chevrolet Equinox report other speed control problem at a median of 75,000 miles. A quarter of the reports come in before 50,000 miles and a quarter after 80,000 miles, from 10 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 15,000 miles at the tenth percentile to 105,000 miles at the ninetieth, a spread of 86,526 miles across the middle 80% of reports.
A spread this wide points at use rather than design. Towing, climate, service history and city mileage all move a failure like this, so the median is a weak guide to any individual car.
20% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 17,110 miles | 52,396 miles | 73,773 miles | 77,650 miles | 103,636 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 $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 17 model years of this car. It shows up earliest on the 2020, at a median of 1,700 miles, and latest on the 2008 at 100,000 miles.
By volume the 2011 carries the most reports, with 32; the 2009 has 10. 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 2009 chevrolet equinox. The contact stated that the vehicle would become sluggish when attempting to accelerate and would exhibit signs of wanting to stall. The failure progressed to where the vehicle would not accelerate over 10 MPH. The contact took the vehicle to the dealer and was told that the failure was caused by an internal fault in the throttle body. The vehicle was repaired but the contact was concerned that the failure was not corrected. The failure mileage was 18,978 and the current mileage was 18,911.
While driving in the highway, vehicle warnings suddenly turned on indication that stabili-trac and traction control went off and needed to be serviced. At this time engine lost power and vehicle was sluggish when accelerator pedal was pressed. *tr

The contact also stated that while driving 25 MPH, acceleration power reduced dramatically and the vehicle decelerated to 3 MPH. The contact also stated that both headlights failed and needed to be replaced every 3 months and the brake lights had failed and needed to be replaced. In addition, the windshield wipers failed to operate when activated. The vehicle was taken to the dealer where it was confirmed that the throttle body had failed and needed to be replaced. No other repairs were completed. The manufacturer was not notified of the problem. The approximate failure mileage was 300.

How far this goes
Complaints are voluntary, so 10 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 2009 Chevrolet Equinox?
Across 10 owner reports that included an odometer reading, half were filed by 75,000 miles. A quarter were filed before 50,000 miles and a quarter after 80,000 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 2009 Chevrolet Equinox?
10 reports have been filed with NHTSA, about 0.4 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.
