Complete engine failure or seizure on the 2012 Chevrolet Equinox
When complete engine failure or seizure gets reported
Owners of the 2012 Chevrolet Equinox report complete engine failure or seizure at a median of 85,000 miles. A quarter of the reports come in before 75,000 miles and a quarter after 100,000 miles, from 11 reports that carried an odometer reading.
A part like this is normally expected to survive 105,000 miles. It is the 14th most-reported problem on this model year.
The mileage distribution
The reported range runs from 75,000 miles at the tenth percentile to 110,000 miles at the ninetieth, a spread of 36,866 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 |
|---|---|---|---|---|
| 73,000 miles | 74,771 miles | 83,000 miles | 99,390 miles | 109,866 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 $4,500–$12,000 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 8 model years of this car. It shows up earliest on the 2017, at a median of 60,000 miles, and latest on the 2013 at 130,000 miles.
By volume the 2012 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.
Tl* the contact owns a 2012 chevrolet equinox. While driving approximately 50 MPH, the vehicle stalled and the engine seized. The vehicle was towed to the dealer. The mechanic replaced the fuel pump and fuel control module, and cleared the failure code; however, the failure recurred multiple times. The manufacturer was notified. The approximate failure mileage was 88,913.

My 2012 equinox is currently dead at a chevy dealership. Here is the history: on october 20, 2017 the engine of my 2012 equinox blew at 109,866 miles when key was turned. The engine blew because was absolutely no oil in my engine and no leaks were present. I did not see any lights saying there was an oil problem. In fact, my dashboard read that I had enough oil before the next oil change was needed. I recently purchased an oil change on september 15, 2017 at 108,500 miles. I provided the receipt to dealership. I have always gotten regular oil changes. Recently I had to get oil changes and checks more frequently than gm recommends due to oil missing from my vehicle for no apparent reason or explanation. Because I had to put in so much oil, I would often take my car in for an oil change at a local oil change business or request my father to change/add oil into my vehicle. I travel around se mi and rely on my vehicle for work, so I do not have the time or extra funds to make an appointment take my vehicle into the dealership for monthly oil changes and top-offs (see below).

How far this goes
Complaints are voluntary, so 13 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 complete engine failure or seizure happen on the 2012 Chevrolet Equinox?
Across 11 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 100,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is complete engine failure or seizure on the 2012 Chevrolet Equinox?
13 reports have been filed with NHTSA, about 0.6 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.
