Unclassified problem on the 2010 GMC Sierra 1500
2 crashes 1 injury 3 of the 63 reports for this failure mention a crash, a fire, an injury or a death. Those are the owner's words on the complaint form, not a verified finding, and one report can mention more than one.
Only 43 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 unclassified problem gets reported
Owners of the 2010 GMC Sierra 1500 report unclassified problem at a median of 57,500 miles. A quarter of the reports come in before 40,000 miles and a quarter after 90,000 miles, from 43 reports that carried an odometer reading.
It is the 33rd most-reported problem on this model year.
The mileage distribution
The reported range runs from 35,000 miles at the tenth percentile to 117,500 miles at the ninetieth, a spread of 82,000 miles across the middle 80% of reports.
When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.
14% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 35,400 miles | 40,000 miles | 57,000 miles | 90,993 miles | 117,400 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
Of these reports, 2 a crash and 1 an injury are mentioned. Owners write their own complaints and the agency does not verify them, so read this as what the reports say happened rather than as a confirmed count.
The same failure on other years
The same failure is reported on 27 model years of this car. It shows up earliest on the 2020, at a median of 5,000 miles, and latest on the 1999 at 165,000 miles.
By volume the 2008 carries the most reports, with 106; the 2010 has 63. 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.
Around 37,000 miles a crack appeared on the passenger side dash, around the passenger airbag. There are now 3 cracks around the airbag and these cracks could potentially result in a tear in the airbag during deployment, rendering the airbag ineffective in preventing injury during an accident. From online searches, it appears this might have been a design issue on the 2010 model that was fixed starting with the 2011 trucks. The dealer informed me that there is no recall. I feel that due to the possible safety issue associated with this, the dashes for this model year of sierra should be fixed by gm. *tr
The dash has cracked right above the passenger air bag . The truck was cleaned and detailed on wednesday november 25th 2015 , parked back in the garage and when I left in it friday november 27 , 2015 I noticed the dash was cracked . This is a major concern for me since it is the passenger air compartment and could result in flying debris for an occupant inside my truck .
Hooked up a trailer (first time ever), discovered that the trailer lights were not working, checked fuses, found a melted fuse. Found a recall for same problem, however it is VIN specific and VIN is not covered. Took to dealership, and reported problem to gmc, was told to report it here. Also found a VIN specific recall for the driver control button for the passenger window (sometimes works, sometimes doesn't) and again this VIN is not covered.

How far this goes
This page is kept out of search results because 63 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 63 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 unclassified problem happen on the 2010 GMC Sierra 1500?
Across 43 owner reports that included an odometer reading, half were filed by 57,500 miles. A quarter were filed before 40,000 miles and a quarter after 90,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is unclassified problem on the 2010 GMC Sierra 1500?
63 reports have been filed with NHTSA, about 2.1 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.
