Airbag failed to deploy in a crash on the 2012 Ford Focus
20 crashes 10 injuries 30 of the 21 reports for this failure mention a crash, a fire, an injury or a death. Those are the owner's words on the complaint form, not a verified finding, and one report can mention more than one.
When airbag failed to deploy in a crash gets reported
Owners of the 2012 Ford Focus report airbag failed to deploy in a crash at a median of 50,000 miles. A quarter of the reports come in before 30,000 miles and a quarter after 75,000 miles, from 17 reports that carried an odometer reading.
A part like this is normally expected to survive 72,000 miles. It is the 29th most-reported problem on this model year.
The mileage distribution
The reported range runs from 30,000 miles at the tenth percentile to 110,000 miles at the ninetieth, a spread of 76,960 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.
47% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 31,000 miles | 31,000 miles | 51,000 miles | 75,000 miles | 107,960 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
Of these reports, 20 a crash and 10 an injury are mentioned. Owners write their own complaints and the agency does not verify them, so read this as what the reports say happened rather than as a confirmed count.
Putting it right typically runs $1,000–$5,000 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.
This mode is classified as critical, which means a failure can leave the car unable to stop, steer, or stay out of the way of traffic. It is weighted accordingly in the risk score.
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 15,000 miles, and latest on the 2006 at 150,000 miles.
By volume the 2012 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.
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.
In june 2012, my daughter was driving and her front passenger tire exploded. This was the 3rd set of new tires we had placed on this vehicle (by 30,000 miles - averaging 10,000 miles per set of tires). Then in july 2012, she was driving home and started to skid. She was not able to recover from the skid and hit a tree head-on. The front of her car was destroyed. The tree centered her car and the front end looked like a volkswagen bug. The air bags did not deploy. We had this vehicle into the dealership 3 times for problems with the front end. Each time they said they could not find anything wrong with it. However, the driver and passengers could feel the car sway when riding it in. The vehicle was totaled by the insurance company ($17,000 check sent to ford) and we still owe $1700 that we have agreed to pay to ford to keep from ruining our credit. Thank god she was wearing a seat belt that actually worked - otherwise we would have had to plan our daughters funeral. We purchased this car because it was advertised as being a very safe car with the interior wrapped in air bags. Wrapping the interior with air bags does not help if…

How far this goes
Complaints are voluntary, so 21 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 airbag failed to deploy in a crash happen on the 2012 Ford Focus?
Across 17 owner reports that included an odometer reading, half were filed by 50,000 miles. A quarter were filed before 30,000 miles and a quarter after 75,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is airbag failed to deploy in a crash on the 2012 Ford Focus?
21 reports have been filed with NHTSA, about 0.1 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.
