Other driver assistance problem on the 2014 GMC Sierra 1500
2 crashes 2 injuries 4 of the 47 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.
When other driver assistance problem gets reported
Owners of the 2014 GMC Sierra 1500 report other driver assistance problem at a median of 70,000 miles. A quarter of the reports come in before 55,000 miles and a quarter after 85,000 miles, from 40 reports that carried an odometer reading.
A part like this is normally expected to survive 45,000 miles. It is the 8th most-reported problem on this model year.
The mileage distribution
The reported range runs from 25,000 miles at the tenth percentile to 130,000 miles at the ninetieth, a spread of 106,600 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.
20% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 24,400 miles | 54,205 miles | 70,575 miles | 86,231 miles | 131,000 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
Of these reports, 2 a crash and 2 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.
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 14 model years of this car. It shows up earliest on the 2024, at a median of 10,000 miles, and latest on the 2018 at 200,000 miles.
By volume the 2014 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.
Was making a right hand turn onto on-ramp, vehicle's brake lights on dash all came on, radio station changed channels and engine hesitated. Warning lights on dash went out, radio stayed on switched channel, engine returned to normal, but service stability track information came up on panel. Service warning went off in about 300 yards, vehicle returned to normal operation. *tr
Tl* the contact owns a 2014 gmc sierra 1500. While driving 40 MPH, another vehicle crashed head on into the contact's vehicle. The air bags failed to deploy. A police report was filed. The contact sustained severe whiplash and a concussion, which required medical attention. The vehicle was taken to the dealer. The manufacturer was made aware of the failure and sent an engineer to inspect the vehicle. Shortly after, while driving at an unknown speed, the stabilitrac warning light illuminated and the power steering malfunctioned. The steering wheel jerked violently. The vehicle was towed back to the dealer. The technician diagnosed that all the steering electronic sensors needed to be replaced. The vehicle was repaired. The failure mileage was 19,000.
The problem started while backing a trailer and turning. The stabiltrack light came on and the steering wheel jerked out of my hand. It happened a few more times and then the truck died. Later while driving the stabilitrack light would flash on and the dic would go black. The a.c. Would also go out and come back on. It would also do this when turning on the signal light or stepping on the brake pedal. I was in a parking lot today driving slowly and the st message came then the dic went black again. When I tried to turn the wheel it started jerking back and pulled out of my hand. It seems that shutting the truck off and restarting solves the problem for a day or two. This is a very unsafe issue and I have seen and read many complaints. I have been a huge fan of gm and all I have ever owned were gm vehicles, but this issue is making me wonder if I should have bought a ford instead. It seems that gm is not worried about recalling because of this safety issue, which there are many complaining of the same thing, and my warranty is about to run out.

How far this goes
Complaints are voluntary, so 47 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.

How common is other driver assistance problem on the 2014 GMC Sierra 1500?
47 reports have been filed with NHTSA, about 0.2 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.
