Other brake problem on the 1999 Audi A6
1 crash 1 of the 6 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.
Only 2 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 brake problem gets reported
There are 6 reports of other brake problem on the 1999 Audi A6, 2 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 88,000 miles. It is the 15th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 87,385 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, 1 a crash is 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 $300–$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 8 model years of this car. It shows up earliest on the 2019, at a median of 400 miles, and latest on the 2003 at 95,000 miles.
By volume the 2001 carries the most reports, with 7; the 1999 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.
Driving home tonight my car all of a sudden started accelerating (I drive an audi a6 1999). Using the brakes I was able to slow it down enough to get off the freeway though my brakes seemed to be fighting against the car. I rolled through two stop signs as my car would not stop and luckily avoiding the other cars waiting there I was able to put my car in park and turn off the engine. I waited ten minutes or so and tried starting my car. The engine revved to 4 to 5000 rpms so, I quickly shut it off again. I waited again, tried it once more and the car started fine. I drove home, called the dealership and was told I could be seen on 02/14/11. Four days from now. This is the second time this has happened. *tr
Two vehicles in front of my car on highway came to a stop; I applied brakes, pressing all the way to the floor of the car, and nothing happened - the car did not slow down and the ABS did not engage, despite there being loose sand and salt on the road surface. I rear-ended the vehicles resulting in substantial damage to my car (over $10,000 to repair) and the car I hit (unknown cost covered by my insurance company). My car spent 2 months in the shop having the accident damage repaired. When I picked it up, I tested the brakes and they were very "soft" - I had to press the brake pedal all the way to the floor to get the car to stop, even though I was going no more than 10 MPH. The ABS did not engage that time either. I returned the car to the dealer to fix the brakes. They kept it all day and told me that nothing needed to be done. However, when I tested the brakes again, in the same spot I had tested them before, the brakes worked well and the ABS engaged. On october 31, 2003, the dealership (bernardi audi, 521 worcester road, natick ma; 508-651-9980) serviced the vehicle and supposedly replaced the font and rear brake pads and…

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 brake problem happen on the 1999 Audi A6?
Across 2 owner reports that included an odometer reading, half were filed by 85,000 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 brake problem on the 1999 Audi A6?
6 reports have been filed with NHTSA, about 0.4 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.
