Other driver assistance problem on the 2004 Volvo Xc90
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 other driver assistance problem gets reported
There are 6 reports of other driver assistance problem on the 2004 Volvo Xc90, 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 45,000 miles. It is the 28th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 138,750 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–$1,800 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 4 model years of this car. It shows up earliest on the 2016, at a median of 900 miles, and latest on the 2004 at 140,000 miles.
By volume the 2024 carries the most reports, with 7; the 2004 has 6. 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.
I was driving my xc90 2004 and suddenly the unit just turned off completely. I had to continue driving with the vehicle without any kind of power. I parked the car beside the highway and tried to turned on the car again, the car started to function normally. I checked the pole of the battery but they were ok and the battery itself it's new. This is not the first time that happens, it is very unpredictable and sporadic.when I went to the volvo dealer some months ago to fix a campaign that have the xc90, I told the mechanics what happened and told them to check that issue. The told me it was very strange and when they fixed the campaign they told me they didn't found anything. *tr
While driving at any speed the vehicles electrical system completely shuts down with out warning as if the vehicle was off. The engine stays running with very minimal power. This happened to me at night while driving on the highway, it was raining and all the lights, wipers, every electrical part just shut off, I am lucky I did not crash. After researching I that a lot of owners have the same problems and that volvo is aware of the dangerous problem but does nothing about it.
While driving any distance over 60 minutes the car warning comes on saying sudden loss of brakes, stop safely. Airbag check light comes on. Within a few seconds all the electronics shuts down; all dash, stereo, lights, wipers, windows and lack of power to engine but car stays running. This was almost a deadly crash while driving in pouring rain and there were cars everywhere. No way to signal or flashers, I honestly thought me and my family were gonna get in an accident. I have read other stories online so my question is, what is the cause of this? How do I fix it before some gets hurt or even worse killed! *tr

How far this goes
This page is kept out of search results because 6 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 6 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 other driver assistance problem happen on the 2004 Volvo Xc90?
Across 4 owner reports that included an odometer reading, half were filed by 140,000 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 other driver assistance problem on the 2004 Volvo Xc90?
6 reports have been filed with NHTSA, about 0.2 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.
