Other engine problem on the 2003 Chevrolet Cavalier
1 fire 1 of the 26 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 2003 Chevrolet Cavalier report other engine problem at a median of 40,000 miles. A quarter of the reports come in before 15,000 miles and a quarter after 70,000 miles, from 20 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 6th most-reported problem on this model year.
The mileage distribution
The reported range runs from 5,000 miles at the tenth percentile to 105,000 miles at the ninetieth, a spread of 97,050 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.
50% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 6,350 miles | 13,375 miles | 37,500 miles | 69,675 miles | 103,400 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, 1 a fire 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 $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 9 model years of this car. It shows up earliest on the 2004, at a median of 30,000 miles, and latest on the 2001 at 85,000 miles.
By volume the 1997 carries the most reports, with 63; the 2003 has 26. 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.
Car stalls. This has been reported to the dealer. Car has been to the dealer on 2 occasions for this issue. Always get response, "cannot duplicate the issue." just purchased 2003 cavalier in july of this year. Vehicle only has 7000 miles on it. This began in august. Have been reporting these incidents to the dealer ever since. *la
When coasting to a stop and depressing clutch, car idle speed will drop below the normal idle speed of 800 RPM. Sometimes, the idle speed will bounce around between 400 RPM and 800 RPM. Other times, the engine will stall. Problem is intermittent, but will usually occur multiple times before fixing itself. The stalling engine is a concern because of the lost of power steering making turns. Dealer unable to duplicate problem. *jb
After engine warms up on hot day, engine stalls when clutch is depressed as when coasting to a stop. Enigine will restart, but accellerator must be depressed to rev the engine in order to prevent stalling. If vehicle is parked for several minutes, then restarted, problem with stalling is gone. This problem is very intermittent. The same problem is described in oid numbers 10049266, 10039337 and 10037496.

How far this goes
Complaints are voluntary, so 26 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 2003 Chevrolet Cavalier?
Across 20 owner reports that included an odometer reading, half were filed by 40,000 miles. A quarter were filed before 15,000 miles and a quarter after 70,000 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 2003 Chevrolet Cavalier?
26 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.
