Ignition switch, key fob or immobilizer failure on the 2012 Ford Edge
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 7 reports of ignition switch, key fob or immobilizer failure on the 2012 Ford Edge, 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 22nd most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 35,000 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 6 model years of this car. It shows up earliest on the 2017, at a median of 10 miles, and latest on the 2011 at 45,000 miles.
By volume the 2013 carries the most reports, with 19; the 2012 has 7. 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.
At randon the driver door ajar light & warning will appear. This prevents doors from being locked while the key is in the ignition switch. Door is secure and closed. Warning light will sometimes come on while driving. I am concerned it presents a security issue while driving in some urban areas. Ford dealership where I bought the car said that they had seen the problem before and, since it was outside the warranty period, would cost approx. $300.00 to repair. *tr
My 14 month old, 2012 ford edge, has had numerous issues, some very serious! From the beginning, I have had issues with the sync system, the navigation system, and controlling the temperature. They have had to "update" my sync system more than once. I frequently get a "no key detected" message when driving. (push start system) the first time that happened I pulled off the road thinking it would stop running, and did $1400.00 in damage to the car. (coverage was denied by the wheel and tire protection plan.) later was told the car would not have stopped even if it didn't recognize that the key fob was in it. (a car-jackers dream!) I had a hole in my brake booster causing me to not have the benefit of power brakes. Found this out when I stepped on my brakes and wasn't stopping. I had the really push on them to prevent hitting a car. The battery died in 14 months. The latest is that the vacuum seal in the capless fuel system had a bad o-ring causing fuel to leak and vapors to escape. I truly believe that this car is poorly made. I'm just waiting for the next issue to surface. *tr

How far this goes
This page is kept out of search results because 7 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 7 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 2012 Ford Edge?
Across 7 owner reports that included an odometer reading, half were filed by 35,000 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 2012 Ford Edge?
7 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.
