Misfire or rough idle on the 2014 Dodge Grand Caravan
When misfire or rough idle gets reported
Owners of the 2014 Dodge Grand Caravan report misfire or rough idle at a median of 105,000 miles. A quarter of the reports come in before 80,000 miles and a quarter after 125,000 miles, from 14 reports that carried an odometer reading.
A part like this is normally expected to survive 92,000 miles. It is the 5th most-reported problem on this model year.
The mileage distribution
The reported range runs from 40,000 miles at the tenth percentile to 130,000 miles at the ninetieth, a spread of 92,000 miles across the middle 80% of reports.
When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.
0% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 38,000 miles | 80,000 miles | 102,802 miles | 125,000 miles | 130,000 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
Putting it right typically runs $250–$1,600 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 15 model years of this car. It shows up earliest on the 2005, at a median of 25,000 miles, and latest on the 2003 at 165,000 miles.
By volume the 2019 carries the most reports, with 46; the 2014 has 18. 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

Our 2014 dodge grand caravan has the same exact issues as 2011-2013 models with the misfire on cylinder 2 or multiple cylinders, as well as the engine ticking. We have tried to pursue this problem with chrysler via our local dodge dealership. They say it is a mere coincidence. We feel that it is a continuation of the same problem into the new model year, and that their supposed fix for this problem is not what they thought it would be. The engine light came on within hours of purchasing it from a reputable used car dealership. Returned to dealer, they read the code, said it was probably just a fluke, and reset it. A couple hours later it came back on. Brought it back to the dealership. They tried the "easy" fixes (spark plugs, wires, coil) and the engine continued to throw the same code. They brought it to a regular dodge dealership, where they cleaned the injectors, said the problem was solved and sent us on our way. Within hours it threw the same code. Called the dealership, but they did not respond. We lived 8 hours away, and were halfway home at that point. So we tried to pursue it with our local dealership, and they are…
Fuel line failure while merging onto major highway. This resulted in loss of acceleration and power steering on the highway. Vehicle coasted / rolled to the next available highway exit. Upon inspection of the engine compartment, I observed boiling liquid; vehicle was non-functional and had to be towed to dealer. Odb scanner reported it as a #2 cylinder failure. Prior to highway failure, van had problems with the check engine light resulting from a #2 cylinder misfire. Took the van to dealer and they did not find the correct problem, so paid twice for service. The first payment to fix resulted from the charge for inspection from the check engine light. Second charge resulted after needing to have the vehicle towed to the dealership, and after the dealer fixed the fuel line issue.

How far this goes
Complaints are voluntary, so 18 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.

How common is misfire or rough idle on the 2014 Dodge Grand Caravan?
18 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.
