Used Ford F-350 6th Gen (2023-2026): Buyer's Guide

Ford recalled the F-350's left rear axle shaft in 2023 because it wasn't heat-treated correctly and could snap under load. In January 2026, Ford recalled the right rear axle shaft on 2026 trucks for the exact same defect. Same truck, same supplier problem, three years apart, opposite side. If you're shopping a used 2023-2026 F-350 Super Duty, that pattern tells you more about what to check before you buy than any spec sheet does.

This is Ford's first ground-up Super Duty redesign since 2017. The F-350 shares its cab, frame, and electronics with the F-250, but the buying calculus is different: dual rear wheels are on the table, the GVWR is heavier, and the recall list has its own F-350-specific entries. This guide covers what actually matters if you're cross-shopping a used single or dual rear wheel F-350 from this generation.

This Generation at a Glance

Ford redesigned the Super Duty lineup for 2023 on the P702 platform: a new front end, a fully digital cockpit with an 8-inch or 12-inch touchscreen, and two new gas engines to replace the outgoing 6.2L V8. The frame and cab structure carry over from the prior truck, so this is a major refresh rather than a clean-sheet platform, but the electronics, cameras, and driver-assist systems are essentially all new, which is exactly where most of this generation's early recalls landed.

2025 marks the clearest internal dividing line. Ford dropped the range-topping Limited trim in favor of a Platinum Plus package (which requires the diesel), cut the SuperCab down to XL and XLT only, and killed the SuperCab dual-rear-wheel F-350 entirely. If you want a SuperCab dually, you need a 2023 or 2024 truck. The F-350 also comes in single rear wheel (SRW) or dual rear wheel (DRW) configurations that F-250 buyers never have to think about, and that choice affects which recalls even apply to your specific truck.

The redesign leaned hard into cameras and driver-assist software: a factory 360-degree camera system, Pro Trailer Hitch Assist, Pro Trailer Backup Assist, and an available onboard scale to weigh payload through the touchscreen. That's genuinely useful for a truck bought to tow and haul, but it's also where a disproportionate share of this generation's early recalls landed. Mechanically, the frame, cab structure, and core drivetrain layout are proven carryovers from the 2017-2022 truck, so the redesign risk sits mostly in electronics, not in the axles and driveline, aside from the axle shaft heat-treatment issue covered below.

Powertrain & Trim Breakdown

All four engines share the same 10-speed TorqShift automatic (the 10R140), and owners on Ford-Trucks.com and the Ford Tremor Forum describe a recurring complaint pattern across engines: harsh or delayed shifts between the upper gears, sometimes severe enough to feel like the transmission briefly drops into neutral. Ford has issued multiple technical service bulletins addressing 10R140 shift quality since this transmission launched, and forum consensus is that most cases resolve with a transmission control module software update rather than a rebuild. Worth a test drive at both low and high RPM before you buy, not just a parking-lot loop.

6.8L V8 (Gas, Standard on XL)

Owners who choose the base 6.8L are usually skipping the diesel on purpose: no DEF tank to keep filled, a simpler emissions system, and a lower purchase price. It shares Ford's "Godzilla" pushrod V8 architecture with the 7.3L above it, just with less displacement and less power. Real-world fuel economy from owner reports runs in the low teens combined, worse when loaded. It's the entry point of the lineup, and most buyers pair it with an SRW work-truck configuration rather than serious towing.

7.3L "Godzilla" V8 (Gas, Standard XLT and Up)

Step up to XLT and the 7.3L becomes the standard gas engine: 430 hp and 485 lb-ft. Owners on Ford-Trucks.com and the Ford Tremor Forum report a rough idle on some trucks, which dealers have traced to dirty injectors, vacuum leaks, or a faulty idle air control valve rather than a design defect. A misfire-and-power-drop complaint tied to firing-order calibration on early Godzilla-family engines got a software fix from Ford. Some owners also report a "Check Fuel Fill Inlet" warning triggered by fumes reaching the cab, a $100 to $500 fix. Fuel economy complaints are consistent across forums: this is a big, thirsty pushrod V8, with real-world combined mileage commonly reported in the low-to-mid teens unloaded.

6.7L Power Stroke (Diesel, Standard Output)

The third-generation 6.7L Power Stroke carries into this platform making 475 hp and 1,050 lb-ft. It's the same core engine architecture that powered the outgoing 5th-gen truck, and it inherited the same reputation, good and bad. The bad: a Bosch CP4.2 high-pressure fuel pump that, on failure, can send metal fragments through the fuel rails and injectors, with owner-reported repair bills of $8,000 to $12,000. It doesn't always take contaminated fuel or a skipped filter change to trigger it; forum threads describe well-maintained, low-mile trucks losing a pump too, which is why it's worth budgeting for regardless of how clean the maintenance records look. Ford has never issued a recall for the CP4 issue; it's been the subject of class-action litigation since 2020. EGR cooler fouling and turbo actuator wear are the other long-documented weak points on this engine family, discussed across a decade of Power Stroke ownership threads, and both show up as a gradual loss of power or a check-engine light rather than a sudden failure, so they're catchable on a pre-purchase inspection. The good news for 2023-and-later trucks: multiple diesel-focused sources describe this refreshed 6.7L as the most reliable version of the engine yet, with fewer forum fault reports than the outgoing 5th-gen truck.

6.7L Power Stroke High-Output (Diesel)

The HO variant bumps output to 500 hp and 1,200 lb-ft, added mid-cycle as the range-topping engine and paired with a new water-cooled turbo not used on the standard 6.7L. It's standard on the Limited trim (2023-2024 only) and available on Platinum and King Ranch. Reviewers running back-to-back tow tests report the HO pulling a loaded trailer with noticeably less strain than the standard 6.7L, and owners on YouTube and diesel forums report fuel economy in the low 20s unloaded, dropping into the mid-teens under a heavy tow. It's the newest iteration of this engine and hasn't developed a distinct failure pattern separate from the base 6.7L: the CP4 and EGR concerns above apply here too, since it's the same core block with a different tune. One wrinkle worth knowing before you shop: once Ford discontinued the Limited trim for 2025, the HO diesel stopped being a standard-fitment engine on any trim. If you specifically want HO power without paying to option it on Platinum or King Ranch, a 2023 or 2024 Limited is the only way to get it standard.

Diesel trucks of either output add a DEF (diesel exhaust fluid) tank that needs periodic refilling, roughly every 5,000 to 10,000 miles depending on load, and a low-DEF warning that will eventually limit engine power if ignored. It's a minor recurring cost, but it's one more system to check the history on when you're evaluating a used truck versus a comparable gas model.

Trim Levels

The single-versus-dual-rear-wheel decision matters more on an F-350 than almost any other truck in this class. DRW adds stability and towing capacity (up to roughly 28,000 lbs with a conventional hitch on a loaded DRW HO diesel, versus roughly 18,000 lbs SRW, per Ford's own towing guides) at the cost of a wider track and a harder time parking. It also changes which recalls apply: the 2023 rear axle shaft recall covered only SRW trucks with the 10.5-inch axle, so a 2023 DRW truck was never part of that campaign. And if you want a SuperCab dually specifically, your window closed after 2024.

Cab choice follows a similar trim split. Through 2024, XL and XLT could be had in regular cab, SuperCab, or crew cab; Lariat, King Ranch, and Platinum were crew-cab only. Starting in 2025, SuperCab dropped to XL and XLT exclusively and lost its 148-inch-wheelbase and dually options, so a used SuperCab F-350 in any of the nicer trims only exists as a 2023 or 2024 truck. The off-road-focused Tremor package, available on 4x4 diesel trucks, adds factory skid plates, a stiffer front stabilizer bar, off-road tuned dampers, and 35-inch tires. Forum threads from early Tremor buyers flagged some fit-and-finish and electronics teething issues in the first model year, consistent with the broader 2023 launch pattern rather than anything specific to the package itself.

Which Model Years to Target Within This Gen

This is according to CarScout's NHTSA-sourced data, checked per model year. 2024 is the sweet spot: it's a straight carryover of the 2023 redesign after the worst of the launch-year electronics and camera issues got fixed, and before the 2025 changeover introduced its own new problems, including a shifter mechanism that could weld improperly and detach from the steering column (25V163000) and a brake pedal pushrod spring that could go missing entirely, causing sudden brake loss (25V401000, a do-not-drive recall). 2023 is not a truck to avoid outright, but budget the time to confirm every recall on that VIN is closed, not just the headline ones. Two separate 2023 campaigns (23V573000 for the rearview camera during Pro Trailer Hitch Assist use, and 23V507000 for the anti-pinch power windows) were fixed incorrectly the first time and had to be recalled a second time in 2025 to actually work.

2026 is a harder call, and not just because it's newest. The right rear axle shaft recall (25V866000) is a near-mirror of the 2023 left-side campaign: same improper heat-treatment defect, same consequence, different side of the truck, roughly three years apart. That's not a reason to rule out a 2026 truck, but it's a reason not to assume Ford has fully closed the loop on axle shaft manufacturing quality for this generation. Combined with thin used inventory this early in the model year, most buyers are better served waiting for 2026 trucks to accumulate more ownership history, or targeting the 2024 model year instead.

Pre-Purchase Inspection Checklist

Organized so you can jump to your powertrain.

Every F-350, any engine:

• Put the truck in reverse and confirm the rearview camera image is clear, not blue, black, or flickering. Water intrusion into the tailgate camera module (24V806000) hit 2023-2024 trucks specifically.
• If it's a 2023 model, ask for the dealer paperwork on the rear axle shaft recall (23V595000, SRW trucks only) and confirm it's closed, not just scheduled.
• If it's a 2025 model, confirm the steering column shifter recall (25V163000) and the brake pedal pushrod recall (25V401000) are both closed. The brake one was serious enough that Ford told owners not to drive until repaired.
• If it's a 2025 or 2026 truck with an aluminum rear driveshaft, ask about 26V119000, the driveshaft separation recall.
• If you're buying to tow, hook up a trailer and test the brake controller through a full stop. A 2022-2026 recall (26V104000) covers the integrated trailer module losing communication and dropping trailer lights or brakes mid-tow.

Diesel (6.7L or 6.7L HO):

• Cold start the truck and listen for any whine or ticking from the high-pressure fuel pump area before assuming it's normal diesel clatter.
• Check maintenance records for regular fuel filter changes; contaminated fuel is the leading cause of CP4 pump failure.
• Have a shop check the EGR cooler and turbo actuator for excess soot or sluggish response on a pre-purchase inspection.

Gas (6.8L or 7.3L):

• Let it idle for several minutes cold. A rough or hunting idle is a known complaint on early Godzilla-family engines and is usually fixable, but it's a fair reason to knock money off the asking price.
• Watch for a "Check Fuel Fill Inlet" warning light on the dash.

Tremor and off-road trucks:

• Inspect skid plates and the front stabilizer bar for impact damage or rust from off-road use, and check that the factory off-road tune hasn't been overwritten by an aftermarket tuner without disclosure.

Run the VIN through CarScout's recall lookup before you commit to any of this in person.

Running Costs

Class 2b and 3 trucks like the F-350 are exempt from EPA fuel economy labeling, so there's no window-sticker number to check against. These figures come from owner-reported ranges across diesel and Super Duty forums, and they swing hard with load, gearing, and driving style: one owner logged 14 mpg towing 23,000 lbs at highway speed, well under what the same truck gets empty.

Beyond fuel, DRW trucks cost more to keep on the road day to day: six tires instead of four, and dually-specific replacements aren't cheap or universally stocked at every tire shop. Insurance also runs higher on the diesel and DRW configurations than on a base SRW gas work truck, since replacement cost and repair complexity both factor into the premium. None of this is unique to the F-350, but it's easy to underweight against the sticker price when you're comparing a used gas SRW truck to a used HO diesel DRW truck side by side.

FAQ

Is the 2023-2026 Ford F-350 Super Duty reliable? Generally, yes, especially 2024 and later. The 6.7L Power Stroke carries into this generation with a strong reputation, and multiple diesel-focused sources call it the most reliable version of the engine yet. The main drag on reliability is the 2023 launch year's recall volume, not the hardware itself.

What year F-350 Super Duty should I avoid? None outright, but 2023 needs the most homework. It carries 15 separate NHTSA campaigns in CarScout's data, including two that Ford had to fix a second time in 2025 after botching the first repair. Confirm every campaign on the specific VIN is closed before buying.

Should I get the standard 6.7L Power Stroke or the High-Output version? If you're regularly near the truck's max tow rating, the HO's extra 25 hp and 150 lb-ft show up in tow tests as noticeably less strain. If you tow occasionally and under 15,000 lbs, the standard 6.7L does the job for less money and the same core reliability profile.

Is SRW or DRW better for a used F-350? DRW adds towing capacity and stability in crosswinds; SRW is easier to park and drive daily. It's also a recall footnote: the 2023 rear axle shaft campaign applied only to SRW trucks, so a 2023 DRW dodged that specific issue.

Is the CP4 fuel pump still a problem on the 2023-2026 6.7L Power Stroke? It can be. Ford has never recalled the CP4.2 pump, and it's remained the subject of class-action litigation since 2020. Failures are reported less often on this generation than on earlier Power Stroke trucks, but the repair bill is the same $8,000 to $12,000 either way, and clean maintenance records don't guarantee immunity.

Bottom Line

A 2024 F-350 with the standard 6.7L Power Stroke is the safe, boring choice in this generation: past the launch-year recall wave, before the 2025 changeover introduced its own new problems, and cheap enough to skip the HO diesel unless you actually need it. If you tow near the truck's limits regularly, the High-Output diesel and a DRW rear end earn their keep. Whichever year and configuration you land on, run the VIN through a recall check and don't take a dealer's word for it that a campaign is closed; ask for the paperwork.
