How reliable is the Ford F-350?
In general, the Ford F-350 Super Duty is a capable and dependable heavy-duty pickup, especially for towing and demanding work. Reliability varies by model year, engine choice, and how well the vehicle is maintained.
Reliability at a glance
A concise look at what tends to influence reliability in the F-350 and how the current generation stacks up across powertrains.
Gas engines vs. diesel
The F-350 offers both gasoline and diesel options. Gas engines (such as the 6.2L V8 and the 7.3L “Godzilla”) are typically straightforward to service and can deliver solid long-term durability with regular maintenance. The 6.7L Power Stroke diesel is renowned for torque, towing capability, and durability, but it requires disciplined diesel-specific maintenance (DEF management, filters, cooling, and emissions-system care) and often higher ongoing upkeep costs.
- Gas engines: generally simple maintenance with reliable long-term performance when serviced on schedule.
- Diesel engine: exceptional durability for heavy-use towing, but higher maintenance and repair costs; emissions-system components demand attention.
Conclusion: Both powertrains can be reliable; the best choice depends on how you use the truck and your willingness to manage diesel-specific maintenance needs.
Transmission reliability across generations
The current F-350 uses a 10-speed automatic transmission paired with both gas and diesel engines. Early 2017–2019 models reported some software and shift behavior quirks, which Ford addressed with updates and service campaigns. In later model years, owners generally report smoother operation, especially during towing, with fewer major transmission incidents.
- Early-generation software and shift-characteristics were mitigated by updates.
- Later years show improved reliability and smoother towing performance.
Conclusion: Transmission reliability improves with later model years; when buying used, verify that required software updates and TCM calibrations have been performed.
Common reliability concerns by generation
Owner feedback and recall history point to patterns, though experiences vary with maintenance and usage.
- 2017–2019: Post-redesign growing pains common in the first few years, including transmission and electronic system refinements; diesel-maintenance remains critical for long-term reliability.
- 2020–2023: Ongoing refinement of engine and transmission controls; diesel emissions systems require routine DEF/DPF maintenance; overall reliability remains solid for a heavy-duty truck with proper care.
- 2024–present: Continued updates and incremental reliability improvements; ownership outcomes largely hinge on maintenance discipline and timely service.
Conclusion: Reliability tends to be strongest in trucks with complete maintenance histories and few missed service intervals; model-year nuances matter for long-term ownership.
Maximizing reliability and ownership value
Owners who prioritize reliability tend to follow a proactive maintenance approach and monitor for early signs of wear, especially in diesel-equipped models.
- Adhere to the manufacturer’s maintenance schedule, including frequent oil changes and diesel-specific services for the Power Stroke.
- Keep cooling systems in good shape, as overheating can impact both gas and diesel engines under heavy load.
- Install and update vehicle software as recommended by Ford to resolve electronics and drivetrain calibration issues.
- Be vigilant for diesel-system issues (DEF, DPF, and exhaust components) and address anomalies early to avoid costly repairs.
Conclusion: Routine, preventive maintenance is the primary driver of reliable performance and reasonable ownership costs for the F-350.
Buying a used Ford F-350: reliability checks
When shopping used, use a checklist focused on service history, recall status, and current condition to gauge reliability and remaining lifespan.
- Review complete maintenance and service records, with emphasis on oil changes, diesel servicing, DEF/DPF maintenance, and cooling-system work.
- Check for open recalls and confirm that all recall repairs have been completed; verify VIN against NHTSA/Ford databases.
- Test-drive to evaluate transmission behavior, including smooth shifting and absence of shudder or lag, particularly under load or towing conditions.
- Inspect the diesel exhaust and fuel-system components for signs of wear, leaks, or excessive soot buildup; verify proper turbo and injector operation where applicable.
Conclusion: A thorough, VIN-specific check of maintenance, recalls, and drivetrain health helps ensure a reliable used F-350 purchase.
Summary
The Ford F-350 remains a leader in the heavy-duty pickup segment due to its rugged construction, high towing capability, and strong engine options. Gas-powered variants offer straightforward maintenance and robust durability, while the 6.7L Power Stroke diesel delivers top-tier torque and long-haul reliability—with the caveat of higher maintenance costs tied to emissions-control systems. Reliability is most closely tied to model year and maintenance discipline; newer generations have benefited from software refinements and ongoing reliability improvements. For buyers, the reliability picture improves with thorough maintenance records, up-to-date recalls, and careful inspection of the transmission and diesel systems.
