Other engine problem on the 2004 Chevrolet Colorado
When other engine problem gets reported
Owners of the 2004 Chevrolet Colorado report other engine problem at a median of 40,000 miles. A quarter of the reports come in before 20,000 miles and a quarter after 65,000 miles, from 14 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 10th most-reported problem on this model year.
The mileage distribution
The reported range runs from 5,000 miles at the tenth percentile to 80,000 miles at the ninetieth, a spread of 73,153 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.
50% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 5,847 miles | 19,250 miles | 37,500 miles | 64,500 miles | 79,000 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 $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 16 model years of this car. It shows up earliest on the 2016, at a median of 15,000 miles, and latest on the 2009 at 90,000 miles.
By volume the 2006 carries the most reports, with 33; the 2004 has 15. 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.
Vehicle stopped running dealer put a monitor on, and the vehicle had no defect, according to the dealer. Consumer stated that the dealer wanted to sell him another vehicle. *ak
Dt*: the contact stated while driving 65mph up an incline the vehicle began to loose power. The next day the check engine light illuminated. After inspecting the vehicle the independent repair shop reset the check engine light. The problem has not returned.
Vehicles check engine light came on then went off after a couple of days. Vehicle idle dropped to 500 rpms. The truck started to act sluggish and acted as if it would shut off at idle. During acceleration the vehicle was again sluggish. Took the truck to a local shop and had the codes run. It came back as an engine low RPM code. I don't recall the actual code number. Had them do a motor vacuum to clean the fuel system and reset code. The check engine light has gone away and has not come back on. Vehicle does from time to time act as it is going to bog down. I thought that I should submit this complaint because it seems there are several others with the same problem.*ak

How far this goes
Complaints are voluntary, so 15 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 2004 Chevrolet Colorado?
Across 14 owner reports that included an odometer reading, half were filed by 40,000 miles. A quarter were filed before 20,000 miles and a quarter after 65,000 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 2004 Chevrolet Colorado?
15 reports have been filed with NHTSA, about 0.4 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.
