Ignition switch, key fob or immobilizer failure on the 2014 Dodge Grand Caravan
Only 7 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 ignition switch, key fob or immobilizer failure gets reported
There are 10 reports of ignition switch, key fob or immobilizer failure on the 2014 Dodge Grand Caravan, 7 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
A part like this is normally expected to survive 85,000 miles. It is the 6th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 14,000 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–$1,500 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 2014, at a median of 15,000 miles, and latest on the 2012 at 140,000 miles.
By volume the 2010 carries the most reports, with 84; the 2014 has 10. 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.

Rented this vehicle from enterprise rent a car, oriskany blvd, yorkville ny for a family vacation. Driving along rt 81s through pennsylvania when all of a sudden in the passing lane, the vehicle went dead. Had no indication went happened, managed to go across the extreme busy highway to right shoulder of road, knowing that the power steering and brakes would at some point stop working with engine off. This van has the new key fob system with it being in the dashboard, above one's knee. We realized after seeing all the panel lights lite up, the van was off. That is when my son-in-law saw the key on the floor by my feet. I had just re-positioned my right leg due to cramps, and unbeknownst to me, it must of hit the key. No reason this key should of fallen out due to that! Everyone was hysterical when the van went dead thinking someone would hit us and we would die. I asked enterprise for an incident report form and they did not have one, only accident forms. I told the branch manager I was reporting it to your site.

I came out of my house on friday morning (09/26/2014) to find my van parked in my carport with the engine running. Apparently my car had started the engine and ran for about 20 minutes by itself with no human interaction, this is strange because I do not have a remote starter and it does not have the ability to start on its own. As I approached the car I could see that there was no key in the ignition and that the doors were still locked. I have 2 key fobs, both were in my possession, and using one of the key fobs I was able to unlock the drivers door. There was no sign of forced entry, I am the only one living at my residence and no one else had access to the car keys. I found the ignition switch was in the off position so I inserted the key fob and turned it to the on position an back to the off position several times but the engine continued running. I called the dealership that sold me the vehicle and talked with 2 different service technicians but neither one could offer an explanation. They asked me to bring the vehicle in for service, which I did and I am currently waiting on the disposition. After I got off the phone with…

How far this goes
This page is kept out of search results because 10 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 10 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 ignition switch, key fob or immobilizer failure happen on the 2014 Dodge Grand Caravan?
Across 7 owner reports that included an odometer reading, half were filed by 15,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is ignition switch, key fob or immobilizer failure on the 2014 Dodge Grand Caravan?
10 reports have been filed with NHTSA, about 0.2 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.
