Loss of power steering on the 2010 GMC Acadia
When loss of power steering gets reported
Owners of the 2010 GMC Acadia report loss of power steering at a median of 65,000 miles. A quarter of the reports come in before 55,000 miles and a quarter after 75,000 miles, from 14 reports that carried an odometer reading.
A part like this is normally expected to survive 80,000 miles. It is the 7th most-reported problem on this model year.
The mileage distribution
The reported range runs from 50,000 miles at the tenth percentile to 85,000 miles at the ninetieth, a spread of 35,100 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.
0% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 51,900 miles | 55,750 miles | 63,240 miles | 74,750 miles | 87,000 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
Putting it right typically runs $600–$2,800 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.
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 9 model years of this car. It shows up earliest on the 2018, at a median of 30,000 miles, and latest on the 2009 at 95,000 miles.
By volume the 2008 carries the most reports, with 21; the 2010 has 16. 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 2010 gmc acadia. The contact stated that while driving various speeds and attempting to make a turn, there was a sudden loss of power steering. The malfunction occurred for a brief moment. The failure occurred intermittently and on numerous occasions. The vehicle had not been diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 58,000.
The vehicle intermittently loses power steering which makes turning the vehicle very difficult. This initially began happening at very low speeds like when turning into a parking space or entering/exiting our garage. Lately it's begun to occur at higher speeds such as when making turns on roadways. This loss of power steering at higher speeds is a much more dangerous situation as it increases the probability of a crash. This particular issue appears to be a common complaint amongst acadia owners. *tr
Starting slowly and intermittently when making a hard turn to the left from a standing start, power steering lost. This was particularly dangerous when turning into or across oncoming traffic as turning radius truncated and correction ("recovery") became very difficult. Subsequently frequency of occurrence increased and included hard turns to the right. Checked for tsb/recall. Tsb(technical service bulletin) found. Followed recommendation to flush and exchange change power steering fluid. This resulted in correction for a short period of time after which steering intermittently lost with very sluggish steering. Flushed and exchanged power steering fluid for a second time and filled to 1/4 inch above tank full line as some recommended on a tsb website. Unfortunately the power steering failure returned, again intermittently but with increase frequency. There were several near accidents because of the steering fail. Manufacturer/ dealership contacted. The only advice was follow the tsb instructions. Because in my mind and based on my experience with the intermittent and unpredictable power steering failures that have occurred a…

How far this goes
Complaints are voluntary, so 16 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 loss of power steering happen on the 2010 GMC Acadia?
Across 14 owner reports that included an odometer reading, half were filed by 65,000 miles. A quarter were filed before 55,000 miles and a quarter after 75,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is loss of power steering on the 2010 GMC Acadia?
16 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.
