Other engine problem on the 2008 GMC Acadia
2 crashes 3 fires 3 injuries 8 of the 73 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 engine problem gets reported
Owners of the 2008 GMC Acadia report other engine problem at a median of 100,000 miles. A quarter of the reports come in before 70,000 miles and a quarter after 135,000 miles, from 62 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 3rd most-reported problem on this model year.
The mileage distribution
The reported range runs from 17,500 miles at the tenth percentile to 152,500 miles at the ninetieth, a spread of 135,921 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.
15% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 16,300 miles | 70,000 miles | 99,000 miles | 133,938 miles | 152,221 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, 3 a fire and 3 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 $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 17 model years of this car. It shows up earliest on the 2022, at a median of 10,000 miles, and latest on the 2010 at 110,000 miles.
By volume the 2008 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.

Exhaust fumes entering vehicle. When vehicle is running and at a stop, exhaust fumes enter the passenger compartment. All windows are in the up position, and all doors are properly closed during the event. Results in nausea and headache. Occurs every time vehicle is driven. Dealer has not resolved the problem. *tr

Tl*the contact owns a 2008 gmc acadia. The contact stated that the camshaft was failing. There was no acceleration power within the first 100 miles of driving. The contact consulted the gmc dealer and they stated that nothing could be done. On another occasion, when the vehicle was started, the engine light illuminated. The gmc dealer was called again and they offered free maintenance/service (which was included in the contact's extended warranty), but there was no remedy for the failure. The contact stated that the light eventually dimmed, but illuminated again at least 3 more times. The current mileage was 938 and failure mileage was approximately 800.

How far this goes
Complaints are voluntary, so 73 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 2008 GMC Acadia?
Across 62 owner reports that included an odometer reading, half were filed by 100,000 miles. A quarter were filed before 70,000 miles and a quarter after 135,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other engine problem on the 2008 GMC Acadia?
73 reports have been filed with NHTSA, about 1.6 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.
