Cruise control failure on the 1998 Mercury Sable
1 crash 1 of the 7 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 3 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 cruise control failure gets reported
There are 7 reports of cruise control failure on the 1998 Mercury Sable, 3 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 72,000 miles. It is the 11th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 54,000 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 $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 1998 has 7. 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.
While the cruise control was set at 60 MPH, the vehicle stalled then restarted by itself. The dealer could not duplicate or determine the cause of the problem. *ak the cause of the problem was in the switch and a loose wire. The vehicle restarted on it's own and was sometimes hard to start. (hard to start, hot or cold) when the vehicle died at low speeds, it did not restart and was hard to start immediately after but would start within 2-3 minutes. *scc *jb
1) vehicle was having shifting problems with not easily coming out of the 'park" position. Dealer kept stating there was no problem. 2) oct.30--traveling at 70 MPH heading for a downhill with relatively sharp curve at bottom, braked to cancel cruise control with no response. Again braked hard with no response. Cancelled cruise control manually with steering wheel "off" button---just in time to avoid a certain disaster! Later, I engaged the cruise control again on a straight stretch of road and again, the brake did not cancel the system! 3) dealer determined that the brake switch and harness had a strange burn in the wiring. Harness was replaced and (console) shift control and cruise control now are working normally. *jb
On february 14, 2006 as I drove up to my neighbor's garage door, my 1998 mercury sable wagon had 'a mind of it's own'. It would not respond to the brake but accelerated 'on it's own' causing me to go through the door and hit the side brick wall of the garage. The insurance company totaled the car. After much research, I found many such stories with several makes of cars. The cruise control causes an 'sudden involuntary acceleration' which does not allow the brake to work these are only a couple of the links I found. Http://www.safetyforum.com/fordsua/ http://www.antony-anderson.com/cruise/9.5-links.html#ford many people have been injured or killed. Fortunately, I had no injuries except to my emotions. I can still see myself going through that garage door and not being able to stop it. Lorraine barnicle. *nm

How far this goes
This page is kept out of search results because 7 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 7 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 1998 Mercury Sable?
Across 3 owner reports that included an odometer reading, half were filed by 55,000 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 cruise control failure on the 1998 Mercury Sable?
7 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.
