Other engine problem on the 2012 Chevrolet Silverado 2500
Only 6 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 engine problem gets reported
There are 6 reports of other engine problem on the 2012 Chevrolet Silverado 2500, 6 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 95,000 miles. It is the 2nd most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 45,500 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 $300–$4,000 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.
The same failure on other years
The same failure is reported on 22 model years of this car. It shows up earliest on the 2019, at a median of 5,000 miles, and latest on the 1997 at 135,000 miles.
By volume the 2001 carries the most reports, with 40; the 2012 has 6. 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.
When temperatures drop below 30 degrees the tire pressure warning light and the low coolant light comes on. Took to dealership and they advised that both warning lights do that below 28 degrees. This has occurred since 2013 winter. Glow plugs going out one at time gm will only replace as they go out up to 120000 not enough being done with this.
I have been having multiple glow plug failures on my vehicle. One right after another. It has gone to the dealer every single time for the repairs I even asked the dealer mechanic if I was the only one and he stated that there are many others with my issue with failing glow plugs. The dealer has a full record of all the issues iv had and every time my vehicle has been in their shop. Something has got to be done! Soon as I try to use my remote start the truck starts then dies then I get a check engine light so I call onstar they give me the code and sure enough its a failed glow plug. Then im unable to even use remote start features of my vehicle at this point.
Several problems.. Multiple failures of "glow plugs" (known gm problem) and nox exhaust sensors, high DEF use, unusual "buildup" in the exhaust filter requiring many dealer visits, downtime, repair costs and extremely poor fuel mileage. Glow plugs often fail at initial start when system is "cold".. Oat has been from about 45 to about 90 degrees fahrenheit. Altitude, about 20 to 1200 ft asl. Dealer serviced only. Vehicle has no mods!!!!

How far this goes
This page is kept out of search results because 6 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 6 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 engine problem happen on the 2012 Chevrolet Silverado 2500?
Across 6 owner reports that included an odometer reading, half were filed by 45,000 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 engine problem on the 2012 Chevrolet Silverado 2500?
6 reports have been filed with NHTSA, about 0.3 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.
