Airbag inflator rupture on the 2008 Lexus IS
Only 4 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 airbag inflator rupture gets reported
There are 7 reports of airbag inflator rupture on the 2008 Lexus IS, 4 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 80,000 miles. It is the 5th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 95,000 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 $0–$0 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 4 model years of this car. It shows up earliest on the 2011, at a median of 40,000 miles, and latest on the 2007 at 150,000 miles.
By volume the 2010 carries the most reports, with 12; the 2008 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.
Takata recall I am in zone b and my car is approaching its ten year mark. I took my car in today and asked the sales assistant if there were any updates about the airbag recall and he told me, "no". What is supposed to save me in an accident can now kill me. I am very disappointed in the amount of time this has taken and the response to consumer concern. Please put pressure on toyota and takata to fix our airbags.
Takata recall. We were told by lexus 8 months ago not to allow anyone to drive in the passengers seat. Since we always ride together we can no longer use the car. It does not make sense that we bought a car this expensive we can no longer use.
Takata recall the local lexus dealer and car maker, lexus automobiles, are taking an unacceptably long time to remedy this life-threatening defect. This week I have received a letter from the car maker with a warning to not let anyone sit in the front passenger seat when the car is being operated. This is the second mailing I have received, and the problem is described as more critical with each mailing. Since june of 2016 I have been on a waiting list with the local dealer to have the takata device replaced. This delay is not a reasonable period to wait. Furthermore the local dealer, lexus of thousand oaks, is not diligent in assigning people to the recall repair waiting list. My wife called the dealer twice in early 2016 and was assured that our car was assigned. I visited the dealer in summer of 2016 and found that our car was not on the dealer recall repair list. So, only by visiting the dealer was I able to definitely be assigned to the list. Very poor oversight by the car maker of a critical issue being handled by the dealer. The car maker should step-up and create a waiting list website that schedules appointments at any…

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 airbag inflator rupture happen on the 2008 Lexus IS?
Across 4 owner reports that included an odometer reading, half were filed by 95,000 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 airbag inflator rupture on the 2008 Lexus IS?
7 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.
