Strut, shock or spring failure on the 1999 Dodge Grand Caravan
When strut, shock or spring failure gets reported
Owners of the 1999 Dodge Grand Caravan report strut, shock or spring failure at a median of 100,000 miles. A quarter of the reports come in before 80,000 miles and a quarter after 125,000 miles, from 22 reports that carried an odometer reading.
A part like this is normally expected to survive 105,000 miles. It is the 4th most-reported problem on this model year.
The mileage distribution
The reported range runs from 70,000 miles at the tenth percentile to 185,000 miles at the ninetieth, a spread of 115,207 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.
0% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 70,500 miles | 79,000 miles | 99,500 miles | 123,000 miles | 185,707 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 $500–$2,000 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 5 model years of this car. It shows up earliest on the 2000, at a median of 92,500 miles, and latest on the 1997 at 150,000 miles.
By volume the 2000 carries the most reports, with 63; the 1999 has 34. 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.
The left front strut tower, where the suspension was bolted to the vehicle, rusted out. The strut can fall off the vehicle at anytime without warning. *ak when the vehicle was first purchased, the consumer noticed minor rust on the strut tower right hand side only. The consumer said that there were others with the same problem. *scc *jb
Car was reported to (chrysler) to have rust at weld seams in various places, but only on the drivers side of the van. The vehicle was at the end or only one week out of warranty and the chrysler service rep. Would not even look at the problem. It is an obvious manufacturing defect from improper paint / weld prep and could cause a serious accident (shock tower rust). The shock tower rust is admitted in a factory service bulletin, but is not a current recall (as per ford's recent recall) that could cause the strut to punch through the shock tower and lodge into the engine bay, causing an accident / vehicle fire. Additional areas of rust exist at the bottom of the door slider at the rocker and around the rear wheel lip. Van is garage kept and washed regularly, never been in an accident and does not operate in a corrosive environment. Absolute poor workmanship has LED to this defect.*ak

How far this goes
Complaints are voluntary, so 34 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 strut, shock or spring failure happen on the 1999 Dodge Grand Caravan?
Across 22 owner reports that included an odometer reading, half were filed by 100,000 miles. A quarter were filed before 80,000 miles and a quarter after 125,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is strut, shock or spring failure on the 1999 Dodge Grand Caravan?
34 reports have been filed with NHTSA, about 0.5 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.
