Airbag warning light or occupant sensor fault on the 2009 Subaru Outback

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 airbag warning light or occupant sensor fault gets reported

There are 7 reports of airbag warning light or occupant sensor fault on the 2009 Subaru Outback, 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 4th most-reported problem on this model year.

The whole distribution

Percentiles of the 7 odometer readings owners gave.
10th25thMedian 75th90th
— — 70,503 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 $300–$1,600 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 9 model years of this car. It shows up earliest on the 2011, at a median of 5,000 miles, and latest on the 2007 at 145,000 miles.

By volume the 2008 carries the most reports, with 40; the 2009 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.

The airbag light on the dash would intermittently turn on. If I turned the car off and then right back on the light would go out. Eventually the light would come back on, so I took the car to the dealer who had a technician check the computer codes. It listed (code 26-right front seat belt error). The technician reset the computer and the computer error code was cleared. The tech told me that eventually it was going to happen again, as he had seen the problem several times before in the 2008/2009 year range of outbacks & legacy's and told me that when the dash light was lit, "none of the airbags would work in a collision". All was well for a few weeks and the light did come back on, so the vehicle was taken to the dealer to be repaired. The problem seems to be the map light/passenger seatbelt lamp assembly (part # 84621ag53a) that is located on the interior roof directly next to the rear view mirror. I was informed that this part is not covered by any warranties, as the airbags are a "supplemental system", unlike seatbelts which "are covered" as the primary restraint system. It seems to me that subaru must obviously be aware of…

"air bag" warning light in the instrument panel (combination meter) is on. The airbag light has come on since it has been cold out. It keeps on every cold day. It is a safety issue and if possibly not deploying the SRS to protect driver and passenger in a collision. This problem was reported by many drivers of subaru, but subaru company is still no response. *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 airbag warning light or occupant sensor fault happen on the 2009 Subaru Outback?

Across 7 owner reports that included an odometer reading, half were filed by 70,000 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 warning light or occupant sensor fault on the 2009 Subaru Outback?

7 reports have been filed with NHTSA, about 0.3 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.
