Fuel tank, filler or EVAP failure on the 2007 Chevrolet Equinox
When fuel tank, filler or evap failure gets reported
Owners of the 2007 Chevrolet Equinox report fuel tank, filler or EVAP failure at a median of 85,000 miles. A quarter of the reports come in before 75,000 miles and a quarter after 105,000 miles, from 23 reports that carried an odometer reading.
A part like this is normally expected to survive 88,000 miles. It is the 10th most-reported problem on this model year.
The mileage distribution
The reported range runs from 60,000 miles at the tenth percentile to 120,000 miles at the ninetieth, a spread of 59,939 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.
0% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 60,061 miles | 73,628 miles | 83,000 miles | 105,000 miles | 120,000 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–$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 6 model years of this car. It shows up earliest on the 2012, at a median of 25,000 miles, and latest on the 2022 at 130,000 miles.
By volume the 2007 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.
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.
Two weeks ago, started smelling gasoline while driving. Didn't see any obvious leakage. Took to sullivan saturn/chevrolet to have emission repair but they can't identify problem without removing gas tank. They charge for this $500 without knowing the exact problem or if it is covered by emission warranty. The car is two years old and the leak, whether emission or tank should not have happened. I think possible defect and it is very dangerous to drive. This should be covered as a safety issue and emission issue. *tr
My married daughter(3 small kids) recently started smelling gas at the right rear of her 2007 equinox(74,000 mi). Inspection by local dealer revealed gas tank seam near pump/sending unit assembly separated & leaking. Vehicle is still within power train and emissions warranties but gm is only willing to cover cost of new tank(not officially under either warranty, just as a "good will" gesture) leaving $500.00 in labor for her to pay. Per NHTSA website, there have been multiple instances of this problem which could only be described as a component failure / manufacturing defect. Given the potential for a fire and/or explosion, gm should view this as a potential p/r nightmare and do whatever is necessary to rectify the situation(to include a loaner vehicle). Local dealer has been very helpful but it's gm's place to do the right thing rather than taking 'partial responsibility'. Two or more similar problems reported to NHTSA have been covered under warranty. Compared to the cost of a recall(or god forbid, a fire), repairing each of these as they happen without hesitation would be an insignificant expense for the manufacturer(and very…

How far this goes
Complaints are voluntary, so 28 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 tank, filler or evap failure happen on the 2007 Chevrolet Equinox?
Across 23 owner reports that included an odometer reading, half were filed by 85,000 miles. A quarter were filed before 75,000 miles and a quarter after 105,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is fuel tank, filler or evap failure on the 2007 Chevrolet Equinox?
28 reports have been filed with NHTSA, about 1.5 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.
