Cruise control failure on the 2005 Mercury Sable
When cruise control failure gets reported
Owners of the 2005 Mercury Sable report cruise control failure at a median of 70,000 miles. A quarter of the reports come in before 65,000 miles and a quarter after 85,000 miles, from 14 reports that carried an odometer reading.
A part like this is normally expected to survive 72,000 miles. It is the 2nd most-reported problem on this model year.
The mileage distribution
The reported range runs from 65,000 miles at the tenth percentile to 115,000 miles at the ninetieth, a spread of 50,368 miles across the middle 80% of reports.
Reports bunched into a band this tight usually mean the component has a life of its own: it goes at roughly the same mileage regardless of who owns it.
7% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 65,482 miles | 66,608 miles | 68,000 miles | 86,700 miles | 115,850 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 $200–$1,400 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 10 model years of this car. It shows up earliest on the 2008, at a median of 35,000 miles, and latest on the 2001 at 120,000 miles.
By volume the 2001 carries the most reports, with 17; the 2005 has 16. 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.
Entered interstate 81, accelerated to 65 miles per hour and set cruise control, drove for several minutes when for no apparent reason the car accelerated to app. 85 miles per hour at which time the cruise control ceased to work. I would like to know if there were any other reports of this happening. *tr
Throttle was randomly sticking upon acceleration; problem became progressively worse and was reproducible at times. On one occasion car was stopped via brake and shifted into park while engine continued to run at 4,000 RPM. Brought car to dealer on 12/02/2010; problem was diagnosed and described as "cruise control cable holding throttle open." dealer replaced part with part no. Yf1z-9a825-ca. (problem was reproducible without any use of cruise control system.) no problems with throttle sticking occurred until approximately 5/20/2012 ( 95,600 mileage) when same behavior began to recur at freeway speeds though without the cruise control being used. *tr
Car suddenly accelerated. I traveling under 30 MPH car began accelerating on it's own! I braked and RPM's continued rev-ving at 3000. Put car in neutral- did not stop rev ving. Placed in park- same thing. Turned it off- same thing when the light turned green I put the car in drive and it peeled away. At that time I tapped the gas and the problem corrected itself. This was the third incident of sudden acceleration. First time in june of 2012- my mechanic cleaned the throttle. However, this time I took it to a ford dealership and the culprit was a broken cruise control cable. Ford/mercury needs to warn consumers to get the cruise control cables checked! Can provide documentation from the dealership if needed. *tr

How far this goes
Complaints are voluntary, so 16 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 cruise control failure happen on the 2005 Mercury Sable?
Across 14 owner reports that included an odometer reading, half were filed by 70,000 miles. A quarter were filed before 65,000 miles and a quarter after 85,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is cruise control failure on the 2005 Mercury Sable?
16 reports have been filed with NHTSA, about 8.4 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.
