2018 Dodge Grand Caravan: what breaks, and at what mileage

What owners report breaking

Owners have reported 43 named failure modes on the 2018 Dodge Grand Caravan, and the three most-reported carry 42% of everything filed.

Other electrical problem leads with 60 reports, about 2.3 per 1,000 vehicles and with the middle half of reports between 42k to 65,000 miles.

Other body or interior problem follows with 53 reports, usually reported between 51k to 70,000 miles.

Ignition switch, key fob or immobilizer failure follows with 36 reports, usually reported between 32k to 55,000 miles.

By system, the reports fall mostly into electrical (113), body (63) and engine (43).

Severity, and what it costs

Across the named modes, 11 mention a crash, 6 an injury and 2 a fatality. Those are the words owners used in their own complaints, and NHTSA does not verify them, but they are the closest thing in this data to a measure of what a failure actually did.

The average severity weight across every report on this year is 3.45, where a stalled engine or a failed airbag weighs many times more than a rattling trim panel, and a figure this high means the reports are dominated by failures with safety consequences rather than annoyances. The weighting is set out in full on the methodology page.

What the top failures cost to put right, as editorial estimates for an independent US shop rather than figures from NHTSA: other electrical problem at $250–$2,000, other body or interior problem at $200–$2,000, ignition switch, key fob or immobilizer failure at $250–$1,500 and misfire or rough idle at $250–$1,600. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.

18% of the reports on this year sit in the engine, transmission, drivetrain or cooling systems — the four where a repair bill is usually four figures.

How often, against how many were built

Scaled by an estimate of how many of these cars exist, the 2018 Dodge Grand Caravan draws about 14 per 1,000 vehicles, which puts it in the 93rd percentile of complaint rates among 2018 vehicles we can rate.

That denominator is the weakest number on the page and it is fair to say so plainly. Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound.

The working figure is 25,722 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2018 vehicles, which is what the risk score uses, is far more robust than the rate itself.

Recalls on the 2018 model year

NHTSA has issued 4 recall campaigns covering the 2018 Dodge Grand Caravan, affecting an estimated 26,308 vehicles. A recall is a different kind of evidence from a complaint: it is the regulator and the manufacturer agreeing that something has to be fixed, and the fix is free for as long as the car exists.

The campaigns cover equipment adaptive/mobility:wheelchair restraints/securement, fuel system, gasoline:storage:tank assembly, service brakes, hydraulic:foundation components:disc:caliper and electrical system:wiring:front underhood. Whether the work was actually done on the car in front of you is a question only the VIN can answer, and the manufacturer or NHTSA will answer it free.

One caution about reading these together: a recall usually raises the complaint count for the same part, because owners who read about it go and file. The mileages stay informative; the counts get noisy.

Better and worse years of the same car

High risk for a 2018 — 222nd riskiest of the 251 2018 vehicles we can rate. The comparison is always within the same model year, so an older car is never penalised for having had longer to break.

Across the 25 model years of this car that carry enough reports to score, 2004 comes out best at 58 and 2020 worst at 80, with 2018 itself at 68.

If the model year is negotiable, 2004 and 2001 score lower than 2018 by a margin worth acting on. Same body, same engines, different luck — usually a supplier change or a mid-cycle fix, which the complaint data can show but never explain.

Within the 2015–2020 generation specifically, 2018 is the strongest year at 68 and 2020 the weakest at 80.

What to look at before buying one

The mileages below are where the first quarter of reports for each mode had already been filed, which makes them the point at which a fault is worth looking for rather than the point at which it happens: ignition switch, key fob or immobilizer failure from about 32k, other electrical problem from about 42k and other body or interior problem from about 51k.

On a 2018 Dodge Grand Caravan with more miles than that on it, the useful question to put to a seller or a mechanic is whether ignition switch, key fob or immobilizer failure has been dealt with, and if so with what parts and at whose expense. A car that has already had the repair is in a different position from one that has not.

Treat it as where to point the inspection, not as a prediction. A well-maintained example can sail past every mileage on this page, and a neglected one can fail well before the first of them.

Where these figures stop being useful

357 owner reports; fleet size estimated from this year's own recall paperwork. Every count on this page is therefore a floor: it is the number of owners who went to the trouble of filing with a federal agency, which is a small and self-selected fraction of the owners who had the fault.

Of those 357 reports, 128 carried an odometer reading, so the mileages here describe 36% of the sample rather than all of it. Owners also round: readings pile up on multiples of ten thousand, which is why this site publishes "about 90,000 miles" and not "91,438".

The failure modes are assigned by software reading the owner's own words, which is accurate in bulk and wrong in individual cases. A mode with a handful of reports may contain a misfiled one.

And nothing here predicts what one car will do. These are other people's complaints, filed years apart, on cars maintained by strangers. Read the page as a map of where this model year has previously gone wrong, then have the specific car in front of you inspected.
