Airbag failed to deploy in a crash on the 2011 Toyota Corolla
13 crashes 6 injuries 19 of the 13 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 2011 Toyota Corolla report airbag failed to deploy in a crash at a median of 70,000 miles. A quarter of the reports come in before 30,000 miles and a quarter after 100,000 miles, from 12 reports that carried an odometer reading.
A part like this is normally expected to survive 72,000 miles. It is the 8th most-reported problem on this model year.
The mileage distribution
The reported range runs from 25,000 miles at the tenth percentile to 145,000 miles at the ninetieth, a spread of 122,800 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.
33% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 22,800 miles | 30,000 miles | 67,800 miles | 101,500 miles | 145,600 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, 13 a crash and 6 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 25 model years of this car. It shows up earliest on the 2021, at a median of 5,000 miles, and latest on the 1998 at 250,000 miles.
By volume the 2014 carries the most reports, with 31; the 2011 has 13. 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.

I was hit by a big rig traveling at approximately 20mph while stopped on the highway, the big rigs impact forced me into the back of an f150xl, causing signifcant damage to the front and rear of the vehicle. The air bags did not deploy. *tr
On may 04, 2013, my mom was involved in a bad traffic accident with her 2011 toyota corolla where the driver's side airbag did not deploy. The insurance adjustor wrote it up as a total loss and advised me to contact toyota to inquire about the airbags not deploying. My mom is currently recovering from two major surgeries from this accident. The first surgery they had to remove her left kidney due to internal bleeding. The second surgery was 41/2 hours long repairing her badly broken right arm. .all parties involved, at the scene of the accident, to the medical staff at the hospital and the towing company all advised me to contact toyota and inquire about the airbags not deploying. The driver parked her car in a bank parking lot to write out a check and wanted to cash it using the bank drive thru. She backed out of the parking spot, misjudging the parking medium / island on her right hand side and started to move forward making a right hand turn. At the time, her car got stuck on top of the medium. After several attempts to free her car by pressing the gas pedal down, the driver lost control of her vehicle after finally breaking…

How far this goes
Complaints are voluntary, so 13 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 2011 Toyota Corolla?
Across 12 owner reports that included an odometer reading, half were filed by 70,000 miles. A quarter were filed before 30,000 miles and a quarter after 100,000 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 2011 Toyota Corolla?
13 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.
