Other suspension problem on the 2018 Ford F-250 SD
1 crash 1 of the 182 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 suspension problem gets reported
Owners of the 2018 Ford F-250 SD report other suspension problem at a median of 26,000 miles. A quarter of the reports come in before 17,000 miles and a quarter after 38,000 miles, from 146 reports that carried an odometer reading.
A part like this is normally expected to survive 100,000 miles. It is the 2nd most-reported problem on this model year.
The mileage distribution
The reported range runs from 10,000 miles at the tenth percentile to 49,000 miles at the ninetieth, a spread of 38,661 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.
72% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 9,839 miles | 17,000 miles | 26,250 miles | 38,000 miles | 48,500 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 $350–$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.
The same failure on other years
The same failure is reported on 22 model years of this car. It shows up earliest on the 2013, at a median of 10,000 miles, and latest on the 2009 at 150,000 miles.
By volume the 2019 carries the most reports, with 634; the 2018 has 182. 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.
Was going around 80 MPH on the interstate this morning and came upon a bridge approach and when I hit the bridge approach I got the 'death wobble'. This happened as I was passing someone the only thing I could do is squeeze tight and slow down to pull over. The wobble would not stop until I was completely stopped. I currently have 10,959 miles on this truck. Same thing happened at this same bridge approach in my 2013 f350.
With less than a 1,000 miles on my 2018 f-250 the truck showed signs of "death wobble" and has become worse over the past 5,000 miles. The early signs have turned into full "death wobble" now and are getting worse. The truck is becoming increasingly difficult to control after hitting bumps in the road, typically crossing bridges.
Hit bump on highway and vehicle starts shaking out of control. This has happened over 5 times now. Ford would only replace steering dampener. It did it again after being in shop for 3 days. This is very dangerous and can only stop the shaking by slowing to a stop in the middle of the road as it is almost impossible to steer. From researching online, this is an ongoing problem referred to as the "death wobble". Ford refuses to look further into the suspension and steering components and claims everything is fine and it was the tire air pressure. The air pressure was to specs. And still did it.

How far this goes
Complaints are voluntary, so 182 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 suspension problem happen on the 2018 Ford F-250 SD?
Across 146 owner reports that included an odometer reading, half were filed by 26,000 miles. A quarter were filed before 17,000 miles and a quarter after 38,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other suspension problem on the 2018 Ford F-250 SD?
182 reports have been filed with NHTSA, about 4.5 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.
