Loss of braking on the 1999 Mercury Sable
1 crash 1 injury 2 of the 9 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 5 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 loss of braking gets reported
There are 9 reports of loss of braking on the 1999 Mercury Sable, 5 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 78,000 miles. It is the 11th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 59,900 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 and 1 an injury are 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 $400–$3,000 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 7 model years of this car. It shows up earliest on the 2000, at a median of 35,000 miles, and latest on the 1998 at 180,000 miles.
By volume the 2001 carries the most reports, with 10; the 1999 has 9. 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.
Total loss of braking while travelling 50 MPH. Pedal went completely to the floor. No lights indicating brake failure lit. Put on flashers, moved to brakedown lane, exited hwy, up hill speed dropped, allowed driver to come against a curb and stop. Brake fluid in resevoir is all very black. Vehicle ha been towed to a shop.
On sunday aug. 17th I drove onto a steep exit from a 4 lane highway to a fiveline highway. I had no brakes. The light at the bottom of the ramp stayed green (there were about 40 cars waiting to enter the intersection)--I crossed all five lanes and crashed my car into a dirt bank. I had no brakes --the man following me said (and told the police) that he smelled a burning ordor or brake smell and had commented to his wife that he thought something was wrong with my brakes before the incident. He advised the police. The police checked the brakes and the pedal was on the floor. I was advised yesterday (8/19) that state farm is totalling the car--that they can find nothing wrong with the brakes. Now there is no way that something did not go wrong with those brakes--my father and I were almost killed. I want to know if other ford sables or taurus--1999 models have had a similar problem?*ak
Total casastropic brake faiure. With my wife driving we encountered a toll plaza on the garden state parkway in new jersey. My wife attemped to slow the car and at that point exclaimed, "I have no brakes"....we went though the toll booths and stopped the car about 100 feet away using the emergency/parking brake. I opened the hood, and checked the level of brake fluid, it was full. I got behind the wheel and started the car and put it in drive. I too found the brake pedal on 'on the floor' with no stopping power, even at low crawl/idle speed. I again stopped the car using the only means, the parking brake. We had the car towed using a new jersey authorized tow company to their facilities. They cheked the car, drove it, pulled all four wheels and found no problem. They test drove the car and found they were unable to duplicate my problem, brakes worked normally. We drove home about 150 miles using caution and the brakes worked normally as they are working now. We are two mature, well experienced drivers, and I am in the auto parts/repair business. I know with certainty that I had no brakes at the toll plaza, and my wife confirms…

How far this goes
This page is kept out of search results because 9 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 9 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 loss of braking happen on the 1999 Mercury Sable?
Across 5 owner reports that included an odometer reading, half were filed by 60,000 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 loss of braking on the 1999 Mercury Sable?
9 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.
