Other driver assistance problem on the 2006 Toyota Prius
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 other driver assistance problem gets reported
There are 11 reports of other driver assistance problem on the 2006 Toyota Prius, 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 45,000 miles. It is the 16th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 30,000 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 $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 14 model years of this car. It shows up earliest on the 2019, at a median of 10,000 miles, and latest on the 2015 at 95,000 miles.
By volume the 2010 carries the most reports, with 38; the 2006 has 11. 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.
2006 toyota prius vehicle stability control (vsc) engages when starting on wet pavement or sand/gravel. This abruptly reduces power, which is a dangerous situation when entering traffic. There is no ability for the driver to disable its operation on acceleration. *tr
I am an owner of a 2006 toyota prius. I don't have a specific date since this type of failure has occurred several times. I construed this to be a part of the prius and did not think of lodging a complaint. But based on today's (2/3/10) report on prius' brake issues from japan, I feel compelled to point out that: there has been a typically recurring problem of the tires skidding as the brakes loose their grip when I have hit the brake as I am crossing a pothole or a road expansion joint or minor bump (not speed bumps) or just a wet spot. This condition has been noted regardless of the condition of the tires - meaning even on brand new tires. The vsc lights comes on when the car glides/skids over and moves past the point where I had wanted to slow down. I am not sure of the type of brake in this vehicle so I will be checking off all 3 kinds. *tr
2006 toyota prius. If it encounters bumpy road while turning and braking, then stability indicator will light up and brakes will stop working for about a second. It feels like the car is being driven on ice. It can be reproduced at will. Just bumpy road surface and turning/braking at the same time. Did not take it to a dealer to have it looked at it though. Learned to live with it. *tr

How far this goes
This page is kept out of search results because 11 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 11 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 2006 Toyota Prius?
Across 7 owner reports that included an odometer reading, half were filed by 30,000 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 2006 Toyota Prius?
11 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.
