Other speed control problem on the 2006 Ford Expedition
1 crash 1 of the 23 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 other speed control problem gets reported
Owners of the 2006 Ford Expedition report other speed control problem at a median of 90,000 miles. A quarter of the reports come in before 80,000 miles and a quarter after 115,000 miles, from 22 reports that carried an odometer reading.
A part like this is normally expected to survive 78,000 miles. It is the 2nd most-reported problem on this model year.
The mileage distribution
The reported range runs from 50,000 miles at the tenth percentile to 140,000 miles at the ninetieth, a spread of 90,050 miles across the middle 80% of reports.
When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.
9% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 49,150 miles | 80,000 miles | 90,000 miles | 113,750 miles | 139,200 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 $250–$2,000 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 21 model years of this car. It shows up earliest on the 2004, at a median of 5,000 miles, and latest on the 2011 at 150,000 miles.
By volume the 2001 carries the most reports, with 54; the 2006 has 23. 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 2006 ford expedition which was purchased brand new. While stepping on the accelerator pedal at any speed including approximately 25 MPH, the pedal became stuck in the open throttle position. The vehicle was taken to the dealer; however, the failure could not be duplicated. The failure was also reported to the manufacturer. There were no recalls. No repairs were made to date. The failure mileage was 10,000 and the current mileage was 45,000.
Driving to work via freeway, had just reached the bottom of a freeway off-ramp, at a stoplight. Light turned green, had just started to go and the "fail safe engine mode" light on my 2006 ford expedition came on the dashboard, within 5 seconds the car turned off on its own, like taking the key out of the ignition. Had it towed to a ford dealership, they ran diagnostics, said the throttle body assembly needed replacing. I looked on the internet, googling "fail safe engine mode" and "ford" and found this to be a common problem. Asked why it's not a recall item or has a technical bulletin with so many cases of it, plus it's very dangerous. Many in their internet postings said the problem comes back. Dealership said to contact ford corporate, opened a cudl case for me to request reimbursement. Wrote a letter to ford corporate, included internet links to all the postings of other people having the same problem, asked for $480.35 reimbursement, also asked what they are doing about this dangerous situation with the throttle body assembly. Ford corporate send me a letter back, simply said I'm past warranty and unable to provide…

How far this goes
Complaints are voluntary, so 23 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 other speed control problem happen on the 2006 Ford Expedition?
Across 22 owner reports that included an odometer reading, half were filed by 90,000 miles. A quarter were filed before 80,000 miles and a quarter after 115,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other speed control problem on the 2006 Ford Expedition?
23 reports have been filed with NHTSA, about 1.6 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.
