Fuel pump failure on the 2011 Chevrolet Equinox
When fuel pump failure gets reported
Owners of the 2011 Chevrolet Equinox report fuel pump failure at a median of 65,000 miles. A quarter of the reports come in before 25,000 miles and a quarter after 110,000 miles, from 24 reports that carried an odometer reading.
A part like this is normally expected to survive 85,000 miles. It is the 10th most-reported problem on this model year.
The mileage distribution
The reported range runs from 15,000 miles at the tenth percentile to 140,000 miles at the ninetieth, a spread of 125,306 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.
33% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 13,859 miles | 25,668 miles | 64,500 miles | 111,475 miles | 139,165 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 $600–$2,600 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 16 model years of this car. It shows up earliest on the 2019, at a median of 10,000 miles, and latest on the 2006 at 105,000 miles.
By volume the 2007 carries the most reports, with 162; the 2011 has 29. 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.
The 2011 chevrolet equinox I purchased on october 8th 2011 began malfunctioning the first time I started it after driving it home (500 miles) from the dealership. On startup there was a loud 3-4 second rattle coming from the engine compartment (almost as if low on oil). This rattle was evident whether the engine was hot, warm, or cold. I took the car into my local chevrolet dealership on 10/11/2011. They reprogrammed the ECM and gave me back my chevrolet equinox. The next day the rattle was still there. On 10/31/2011 I returned my chevrolet equinox to the dealership for the same problem. This time a sound insulator was installed on the high pressure fuel line/fuel pump. The next day the rattle was still there. On approximately 1/20/2012 my chevrolet equinox began idling rough, stalling, and throwing check engine lights. I returned my chevrolet equinox to the dealership on 1/27/2012. On 2/3/2012 I was given back my vehicle and told that it was fixed and appeared to be running ok with no rattle. I took my new chevrolet equinox home and parked it in my driveway to find an oil puddle under it the next morning. In my 53 years I have…
Tl* the contact owns a 2011 chevrolet equinox. The contact stated that the vehicle stalled and hesitated to accelerate when the accelerator pedal was depressed. A diagnostic was performed by a dealer, who stated that the high pressure fuel pump was leaking gasoline into the motor oil. The vehicle was repaired. The details of the repair were unknown. The manufacturer was not made aware of the failure. The failure mileage was 11,000. The current mileage was 11,100. Updated 7/15/13 *cn
I have had many problems with my 2011 chevy equinox that started occurring about a year after I purchased it. The main concerns are the engine noise and how rough it runs, feeling as though I am being rear-ended in traffic (when moving forward from a complete stop it lurches forward, giving the feeling of being hit), rough start up (sounds like an old car at times) and the car stutters when accelerating (almost feels like it wants to stall out). I do not feel safe in this car now and have read that many others are experiencing the same issues. I have taken it four times giving them the same description each time at which they state that they cannot replicate these issues. They keep my car for hours and do nothing to it. I am a single mom so I can't leave my car without it causing major issues for me as I have to take my son to and from school. I received a letter from gm stating that there is an issue with the fuel pump and engine balance chain and describes what my vehicle is doing now-I believe I have engine damage and I am worried that I will end up breaking down on the side of the road at some point or worse stall out and end…

How far this goes
Complaints are voluntary, so 29 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 fuel pump failure happen on the 2011 Chevrolet Equinox?
Across 24 owner reports that included an odometer reading, half were filed by 65,000 miles. A quarter were filed before 25,000 miles and a quarter after 110,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is fuel pump failure on the 2011 Chevrolet Equinox?
29 reports have been filed with NHTSA, about 1.2 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.
