Other engine problem on the 2015 Ford F-250 SD
1 crash 2 fires 3 of the 36 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 engine problem gets reported
Owners of the 2015 Ford F-250 SD report other engine problem at a median of 22,500 miles. A quarter of the reports come in before 10,000 miles and a quarter after 67,500 miles, from 30 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 5,000 miles at the tenth percentile to 105,000 miles at the ninetieth, a spread of 100,750 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.
57% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 5,180 miles | 10,975 miles | 22,250 miles | 67,021 miles | 105,930 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 and 2 a fire 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 $300–$4,000 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.
The same failure on other years
The same failure is reported on 25 model years of this car. It shows up earliest on the 2020, at a median of 5,000 miles, and latest on the 1999 at 135,000 miles.
By volume the 2004 carries the most reports, with 51; the 2015 has 36. 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.
When the cleaning exhaust filter message comes on, the truck runs extremely rough and the engine gets a violent shake with loss of power. It also has a loud pinging sound. This lasts for about two minutes. The first occurrence was when merging on to the freeway with the sudden loss of power. I have had the truck in two dealers. Both state this is not normal but ford has indicated it is and will not authorize work until something breaks. The odd part is that the computer reads that all is ok. The dealer states all is not ok but the issue is something the computer isn't tracking???
While driving down the high the dash display indicated it was start a exhaust clean cycle (regen mode). Within a minute the vehicle began stuttering, loss of power and the engine began knocking. The vehicle lost 15 MPH in a blink of an eye. A very dangerous situation while towing an rv. This lasted for about a minute. Then the engine began to operate normally. This has happened multiple times since the first event. The last occurance was on august 16th. The vehicle has been taken to ford service for an evulation.
When the vehicle is performing a regeneration, and you are going up an incline, the engine can shake and valve knocking can be violent accompanied by a loss of speed and power. The first violent incident that happened was going up a narrow mountain road and fortunately no one was injured. The vehicle has been taken to the ford dealership and contacted ford corporate multiple times and they are unable to correct the issue and unwilling to spend enough time to witness the issue themselves. The loss of power occurs unexpectedly and could cause someone to lose power while merging onto a highway which is unsafe or cause the vehicle behind you to rear end your vehicle when the power loss occurs going up hill.

How far this goes
Complaints are voluntary, so 36 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.

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.
