ABS module or sensor failure on the 2009 Ford Fusion
6 crashes 1 injury 7 of the 75 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 abs module or sensor failure gets reported
Owners of the 2009 Ford Fusion report ABS module or sensor failure at a median of 100,000 miles. A quarter of the reports come in before 70,000 miles and a quarter after 122,500 miles, from 59 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 3rd most-reported problem on this model year.
The mileage distribution
The reported range runs from 47,500 miles at the tenth percentile to 137,500 miles at the ninetieth, a spread of 89,400 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.
8% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 48,000 miles | 69,500 miles | 101,000 miles | 121,500 miles | 137,400 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, 6 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 $500–$2,400 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 12 model years of this car. It shows up earliest on the 2006, at a median of 35,000 miles, and latest on the 2013 at 140,000 miles.
By volume the 2010 carries the most reports, with 108; the 2009 has 75. 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 2009 ford fusion. While driving approximately 40 MPH, the brakes seized without warning. The contact had to pull over to the side of the road. The vehicle was driven home and taken to the dealer the following day where it was diagnosed that the anti-lock brake system failed and needed replacement. The vehicle was not repaired. The manufacturer was notified of the failure. The contact also stated that the failure occurred three other times. The approximate failure mileage was 130,026. Updated 11/01/16*lj *tr
I own a 2009 ford fusion sel with the 3.0 engine. I have a problem with the brakes. The brake pedal is very sponge, I have replaced pads, calipers, and the master cylinder. This has not taken care of the problem, I have reviewed other information and it seems this is a very common problem. Ford has not done anything about it. I have researched more of this problem and the only thing left is the ABS pump and motor. My research shows this has taken care of the problem, the cost to do this is approximately $1500. Plus labor cost. I have not had any close call accidents as some of the other complaints. This is and could be a accident waiting to happen. This problem occurs all the time while driving.
Hit the brakes coming down a hill on wet surface, had a ABS event and the brake pedal went to floor. Had to pump brakes to stop . Now constant soft pedal. No brake light or ABS light came on or have since come on. Had master brake cylinder replaced was not the problem. Researched online and found information saying the ABS system was malfunctioning and many other people have the same problem.

How far this goes
Complaints are voluntary, so 75 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 abs module or sensor failure happen on the 2009 Ford Fusion?
Across 59 owner reports that included an odometer reading, half were filed by 100,000 miles. A quarter were filed before 70,000 miles and a quarter after 122,500 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is abs module or sensor failure on the 2009 Ford Fusion?
75 reports have been filed with NHTSA, about 1.2 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.
