2020 Ford F-350 Power Stroke — Should You Buy One?
Typical asking price: $42,000–$60,000. There is 1 high-severity known issue you need to know before handing over a check.
Kestrel Take
A one-ton workhorse — the F-350 with the 6.7L Power Stroke and the strong 10-speed automatic delivers massive tow and payload capability with modern refinement. As with any HD diesel, the value hinges on emissions-system health, whether it was deleted/tuned, and how hard it was worked. A documented, stock, un-abused dually or SRW F-350 is a hugely capable truck; verify the diesel's history in detail.
What we checked
Partly reconciled against public records, 2026-09-11
NHTSA holds 550 owner complaints for the 2020 Ford F-350 Power Stroke, across 16 recall campaigns.
A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. The largest single group is the transmission and drivetrain at 28%. That is notable without being overwhelming — worth checking, not worth panicking about.
16 recall campaigns cover this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.
Not written up yet: the transmission and drivetrain (153 complaints). That group is in the public record and is not covered by the issues below. Treat it as something to ask about, not as absent.
Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.
