Loss of braking on the 2008 Ford Fusion
4 crashes 1 injury 5 of the 72 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.
When loss of braking gets reported
Owners of the 2008 Ford Fusion report loss of braking at a median of 105,000 miles. A quarter of the reports come in before 85,000 miles and a quarter after 140,000 miles, from 66 reports that carried an odometer reading.
A part like this is normally expected to survive 78,000 miles. It is the 4th most-reported problem on this model year.
The mileage distribution
The reported range runs from 70,000 miles at the tenth percentile to 160,000 miles at the ninetieth, a spread of 90,500 miles across the middle 80% of reports.
A spread this wide points at use rather than design. Towing, climate, service history and city mileage all move a failure like this, so the median is a weak guide to any individual car.
5% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 69,000 miles | 84,032 miles | 104,365 miles | 140,000 miles | 159,500 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, 4 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 12 model years of this car. It shows up earliest on the 2013, at a median of 55,000 miles, and latest on the 2017 at 120,000 miles.
By volume the 2010 carries the most reports, with 89; the 2008 has 72. 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.
Tl* the contact owns a 2008 ford fusion. The contact stated that while driving 20 MPH, the brakes failed. The contact was able to stop the vehicle. The vehicle was taken to an independent mechanic for diagnosis where it was stated that the master cylinder needed to be replaced. The vehicle was repaired and the manufacturer was notified. The approximate failure mileage was 28,000. Updated 12/04/13*lj

After braking on ice, the ABS engaged then the brakes became spongy and the brake pedal went to the floor. It was snowing very badly and the sponginess continued until the car sat still for hours and then the brake pedal pressure returned. Eight months later on a hot, dry day, while braking over a raised joint on the pavement, the ABS engaged and the brakes again became spongy and the brake pedal went to the floor again. We came home and bled the brakes thinking the action of the ABS might have agitated the brake fluid causing bubbles, but the fluid was not foamy only small amounts of air came out. But the brakes two days later are still spongy. We looked on the internet and found forum after forum on websites complaining about this same problem, but there are no recalls on this vehicle, but other ford vehicles have been recalled for ABS issues. I am scared the brakes will fail when I need them the most. *tr

How far this goes
Complaints are voluntary, so 72 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 2008 Ford Fusion?
Across 66 owner reports that included an odometer reading, half were filed by 105,000 miles. A quarter were filed before 85,000 miles and a quarter after 140,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is loss of braking on the 2008 Ford Fusion?
72 reports have been filed with NHTSA, about 1.1 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.
