Unclassified problem on the 2003 Dodge Grand Caravan
4 crashes 4 injuries 8 of the 17 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.
Only 11 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When unclassified problem gets reported
Owners of the 2003 Dodge Grand Caravan report unclassified problem at a median of 65,000 miles. A quarter of the reports come in before 30,000 miles and a quarter after 110,000 miles, from 11 reports that carried an odometer reading.
It is the 53rd most-reported problem on this model year.
The mileage distribution
The reported range runs from 25,000 miles at the tenth percentile to 210,000 miles at the ninetieth, a spread of 187,310 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.
36% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 22,690 miles | 28,094 miles | 65,000 miles | 111,000 miles | 210,000 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
Of these reports, 4 a crash and 4 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.
The same failure on other years
The same failure is reported on 25 model years of this car. It shows up earliest on the 2020, at a median of 5,000 miles, and latest on the 2004 at 220,000 miles.
By volume the 2008 carries the most reports, with 284; the 2003 has 17. 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.
Grand caravan sports are extremely easy to break into and even easier to steal. A 13-year-old with a standard sized screwdriver is all it takes to gain access and drive off with your vehicle <1 minute. Any accomplices are well-hidden by the privacy glass. There are no "cars of choices" for auto thieves, it's whatever is quick and easy. This accessibility issue is common to all daimler-chrysler vehicles, not just the caravan fleet. D.c. Vehicles are quickly gaining status as "easy to steal, quick to stash, not to mention an abundant pool of possibilities"...expect to pay nearly $3000.00 (low end) for someone else's joy ride and wait approximately three to four weeks while repairs are made. *jb

How far this goes
This page is kept out of search results because 17 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 17 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 unclassified problem happen on the 2003 Dodge Grand Caravan?
Across 11 owner reports that included an odometer reading, half were filed by 65,000 miles. A quarter were filed before 30,000 miles and a quarter after 110,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is unclassified problem on the 2003 Dodge Grand Caravan?
17 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.
