Other powertrain problem on the 2004 Kia Spectra
2 crashes 2 of the 14 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 powertrain problem gets reported
Owners of the 2004 Kia Spectra report other powertrain problem at a median of 10,000 miles. A quarter of the reports come in before 5,000 miles and a quarter after 25,000 miles, from 12 reports that carried an odometer reading.
A part like this is normally expected to survive 92,000 miles. It is the 1st most-reported problem on this model year.
The mileage distribution
The reported range runs from 2,300 miles at the tenth percentile to 60,000 miles at the ninetieth, a spread of 55,300 miles across the middle 80% of reports.
A window that narrow is the signature of a part that fails on its own schedule rather than on how the car is driven — which is usually a design or supplier problem rather than wear and tear.
75% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 2,300 miles | 6,943 miles | 8,250 miles | 22,800 miles | 57,600 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 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 $400–$4,500 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 8 model years of this car. It shows up earliest on the 2004, at a median of 10,000 miles, and latest on the 2008 at 145,000 miles.
By volume the 2004 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.
I have had issues with my kia spectra where the transmission fails to shift into a higher gear when at a stop sign or light. I have to pump the gas or shift into neutral and back to drive to get it to shift.*ak
On several instances my car has not shifted into a higher gear when taking off from a stop sign. I have taken the car to the dealer twice and they have not found anything wrong. This has happened on the following dates: 9/11, 9/12, 9/20, and twice on 9/23. *jb
I was stopped in traffic at a light and upon the light turning green I pushed the accelerator and my tachometer needle went up to 4 and higher until I took my foot off the gas. Upon pushing the gas pedal again it did the same thing (in the middle of traffic) and I had to shift into neutral while going about 35 MPH and back into drive. My kia still didn't want to shift so I put it back into neutral again and pushed the gas pedal to rev the rpms and then put back into drive and it drove ok. This happened a few months after buying the car and the kia dealer said nothing was wrong with vehicle. It continues to happen unpredictably.*ak

How far this goes
Complaints are voluntary, so 14 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 powertrain problem happen on the 2004 Kia Spectra?
Across 12 owner reports that included an odometer reading, half were filed by 10,000 miles. A quarter were filed before 5,000 miles and a quarter after 25,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other powertrain problem on the 2004 Kia Spectra?
14 reports have been filed with NHTSA, about 1.0 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.
