Other electrical problem on the 2012 GMC Acadia
2 injuries 2 of the 13 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 electrical problem gets reported
Owners of the 2012 GMC Acadia report other electrical problem at a median of 95,000 miles. A quarter of the reports come in before 85,000 miles and a quarter after 110,000 miles, from 10 reports that carried an odometer reading.
A part like this is normally expected to survive 85,000 miles. It is the 8th most-reported problem on this model year.
The mileage distribution
The reported range runs from 70,000 miles at the tenth percentile to 120,000 miles at the ninetieth, a spread of 48,999 miles across the middle 80% of reports.
Reports bunched into a band this tight usually mean the component has a life of its own: it goes at roughly the same mileage regardless of who owns it.
10% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 71,101 miles | 83,513 miles | 94,500 miles | 109,750 miles | 120,100 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 an injury is 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–$2,000 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 17 model years of this car. It shows up earliest on the 2020, at a median of 5,000 miles, and latest on the 2012 at 95,000 miles.
By volume the 2017 carries the most reports, with 147; the 2012 has 13. 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.
Tl* the contact owns a 2012 gmc acadia. While stopped at a traffic light, the driver seat moved and adjusted on its own when the accelerator pedal was depressed. The seat moved backwards and further away from the steering wheel. The contact stated that the seat slid and tilted. The failure recurred several times. In addition, the contact stated that the vehicle made an unusually loud noise when the remote engine start feature was activated. The dealer was unable to diagnose the cause of the failures. The manufacturer was notified. The approximate failure mileage was 10.
The sensor reading light continues to come on but doesn't match the area its stating. Took car to dealership for service and lights displaying now won't go off. I have replaced tires and air in the tires light still on. Found that to much pressure is in tires and they may burst.
After getting lift gate recall when opened all the way a loud pop would happen. Was told struts worn. Didn't do it before. As of 1 day ago lift gate will open little more than half way then just start closing on its own. It cannot be stopped. Before when it bumped something it would stop or open back up. Now there is no stopping it. If a child wear able to get between it when this happens it would kill them. I was parked trying to get something out of the back of the car.

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 other electrical problem happen on the 2012 GMC Acadia?
Across 10 owner reports that included an odometer reading, half were filed by 95,000 miles. A quarter were filed before 85,000 miles and a quarter after 110,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other electrical problem on the 2012 GMC Acadia?
13 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.
