Other speed control problem on the 2008 Ford F-350 SD
1 crash 1 of the 5 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 5 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 other speed control problem gets reported
There are 5 reports of other speed control problem on the 2008 Ford F-350 SD, 5 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 78,000 miles. It is the 12th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 24,000 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 $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 5 model years of this car. It shows up earliest on the 2017, at a median of 10,000 miles, and latest on the 2000 at 165,000 miles.
By volume the 2003 carries the most reports, with 5; the 2008 has 5. 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 f-350 superduty. The contact stated that the vehicle would surge intermittently. When he would depress the brake pedal in an attempt to stop the vehicle, the RPM's would rev up tremendously and the vehicle would surge like a rocket. He would have to keep the brake pedal depressed while the vehicle continued to "crawl" and he was able to turn off the ignition. The contact stated that the failure only seemed to occur when coming to a stop. He notified the dealer of the issue and had the vehicle inspected; however, they found no failures and stated that there were no recalls available. A complaint was filed with the manufacturer. The current mileage was approximately 25,500 and failure mileage was approximately 24,000.
Tl*the contact owns a 2008 ford f-350 superduty. The contact noticed an intermittent issue with the brakes. When the brake pedal was depressed, the engine would rev and the vehicle would accelerate. Her spouse shoved the gear into park to stop the vehicle. On the second occasion, he kept his foot on the brake pedal until the vehicle finally stopped. The dealer believed that the speed sensors caused the failure. The vehicle is currently being repaired and the manufacturer has not been notified. The current mileage was approximately 2,100 and failure mileage was approximately 800. Updated 06/24/09. *lj updated 06/30/09.*jb
On multiple occasions, when vehicle is stopped, with brake depressed, the engine revs up and vehicle wants to accelerate forward at a high rate of speed. The only way to stop the acceleration is to get the vehicle transitioned in to park and cut the engine. The vehicle has been to three dealers, whom are unable to diagnose and correct the problem. Ford has not been responsive. Vehicle is unsafe to drive. *tr

How far this goes
This page is kept out of search results because 5 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 5 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 2008 Ford F-350 SD?
Across 5 owner reports that included an odometer reading, half were filed by 25,000 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 other speed control problem on the 2008 Ford F-350 SD?
5 reports have been filed with NHTSA, about 1,667 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.
