Is the 2019 F-350 reliable?
Overall, the 2019 Ford F-350 Super Duty is generally reliable for a heavy‑duty pickup, particularly when it is properly maintained and used within its design limits. The diesel variant is recognized for its durability and high torque, which helps with towing and long service life.
In this article, we examine what drives reliability in the 2019 F-350, common issues reported by owners, maintenance considerations, and practical tips for evaluating or owning a 2019 model. We’ll look at the two main engines—the 6.2L gas V8 and the 6.7L Power Stroke diesel—and outline what to check when buying used.
Reliability foundations
Powertrain durability
The 2019 F-350 offered a 6.2-liter gas V8 and the 6.7-liter Power Stroke diesel. The diesel is widely praised for its torque and towing capability, and with routine maintenance it can deliver long service life. Proper oil changes, fuel-quality, and attention to the diesel exhaust aftertreatment system are key to reliability.
Strengths and reliability highlights include the diesel’s robust torque, a heavy‑duty drivetrain designed for demanding work, solid frame construction, and strong parts availability for maintenance and repairs.
- Diesel powertrain’s high torque output supports heavy towing without overworking the engine when properly maintained.
- Durable chassis and components designed for long service life under tough workloads.
- Extensive aftermarket support simplifies parts sourcing and repairs.
- Reliability improves with consistent, manufacturer‑recommended maintenance.
When these strengths are matched with regular service, the 2019 F‑350 tends to deliver dependable performance in typical work‑truck roles.
Chassis and build quality
The F‑350 uses a heavy‑duty chassis and components designed to endure frequent towing and payload tasks. This foundational strength contributes to long‑term reliability, especially in fleet or high‑mile use scenarios where maintenance is kept up-to-date.
Electrical and electronics
Modern Super Duties include a range of electronic controls for engine management, towing, and towing‑related features. Reliability in these areas largely tracks with maintenance history, software updates, and the quality of wiring and connectors in the rig’s environment (dust, salt, vibration).
In short, the core systems are robust, but electronics can be sensitive to neglect or harsh operating conditions if not properly addressed.
Common reliability concerns
As with any heavy‑duty truck, reliability can vary by engine choice, mileage, and maintenance history. The following issues have been reported by some owners and should be considered when evaluating a 2019 F‑350:
- Diesel exhaust and emissions systems can trigger warning lights or require maintenance on the DEF/DPF system
- Diesel‑specific components such as high‑pressure fuel systems and injectors may show wear with high mileage
- Transmission behavior can range from smooth to occasionally abrupt shifts in certain configurations or mileage
- Electrical or infotainment glitches have been reported in some trucks, often resolved with software updates or component replacement
- Front suspension or steering wear can appear in high‑mileage vehicles subjected to heavy payloads or rough winter driving
These issues are not universal and are more likely with high mileage, poor maintenance, or heavy use. Diligent maintenance and a thorough pre‑purchase inspection significantly reduce risk.
Maintenance and ownership considerations
To maximize reliability and minimize surprises, owners should adhere to Ford’s recommended maintenance schedule and stay vigilant about diesel‑specific needs. Consider these practices:
- Follow the maintenance schedule for oil changes, filters, and fluids, with special attention to diesel fuel, DEF, and coolant systems
- Monitor and service the diesel exhaust aftertreatment system (DPF/DPF regeneration) as required to avoid buildup or blockages
- Keep up with brake components, wear items, and regular inspections of the drivetrain, suspension, and steering hardware
- Be aware that diesel ownership generally entails higher maintenance costs but typically offers better long‑term durability for heavy workloads
- Track recalls and service campaigns for your VIN and have them completed promptly
With proactive maintenance, the 2019 F‑350’s reliability remains solid for owners who routinely service the vehicle and address issues before they become major problems.
Buying a used 2019 F-350: what to check
If you’re evaluating a used 2019 F‑350, use this practical checklist to assess reliability and remaining life. Below is a step‑by‑step guide to vetting the vehicle before purchase:
- Review complete service history and verify that all recalls have been addressed for the specific VIN.
- Inspect the engine bay for leaks, worn belts, and signs of heavy towing or over‑loading (excessive soot, oil staining, or coolant seepage).
- Check the diesel‑specific components: DEF system, DPF condition, EGR cooler, fuel system lines, and turbo integrity.
- Assess the transmission and transfer case: test drive for smooth shifts, no slipping, and proper engagement in all drive modes.
- Inspect the exhaust system and mounting hardware for corrosion or damage, especially in regions with road salt use.
- Look for signs of heavy payload use on the frame and rear axle area; inspect mounts, hangers, and bed for unusual wear or deformation.
- Ask for a pre‑purchase inspection by a diesel‑savvy technician to evaluate compression, injectors, and overall engine health.
- Verify tires, brakes, and steering components have adequate life for safe operation and towing capability.
A careful, documented pickup with a known service history and no major red flags is typically a reliable choice within the heavy‑duty segment.
Summary
The 2019 Ford F‑350 Super Duty can be a reliable workhorse, especially the 6.7L Power Stroke diesel, when it is well maintained and used within its design limits. Reliability hinges on diligent maintenance, attentive care of the diesel emissions system, and thorough inspection before purchase. Prospective buyers should prioritize service history, verify recall completion, and consider a professional pre‑purchase inspection to confirm engine and transmission health. With these steps, the 2019 F‑350 remains a strong contender in the heavy‑duty pickup segment.
