What Problems Does the 2021 Ford F-350 Super Duty Have?
The 2021 Ford F-350 Super Duty is generally regarded as a highly reliable heavy-duty truck, built to endure significant work. However, like any complex machine, some issues can be reported or become long-term concerns, particularly for trucks subjected to extreme use or high mileage.
For the 6.7L Power Stroke diesel engine, which is extremely popular, common concerns across modern diesels can include issues with the exhaust aftertreatment system (DEF system, Diesel Particulate Filter - DPF). These components are critical for emissions compliance but can be costly to maintain or repair if they fail, often due to extensive idling or short-trip driving not allowing them to regenerate properly. While Ford's 6.7L is more robust than earlier diesel iterations, injector problems or turbocharger issues, although less frequent, are still possibilities with age and mileage.
The gasoline engines, particularly the 6.2L V8, are known for their simplicity and robustness, with few widespread reported issues. The newer 7.3L "Godzilla" V8, introduced in 2020, has also shown promising reliability. Some owners occasionally report minor electrical glitches related to infotainment systems or various sensors, which can be difficult to diagnose but are rarely critical.
Suspension and steering components, such as ball joints, tie rods, and wheel bearings, can experience accelerated wear under constant heavy loads, especially on trucks that frequently tow or haul near their maximum capacities. This is more of a wear-and-tear item rather than a defect.
Regarding recalls for the 2021 model year, Ford has issued several. Examples include potential issues with the rear axle hub bolts possibly detaching, which could lead to a wheel separation; problems with the windshield wiper motor failing, reducing visibility; concerns with the trailer brake controller software, which could cause intermittent trailer brake function; and potential issues with instrument panel cluster functionality affecting driver warnings. Owners should always check the NHTSA website using their VIN for the most up-to-date and specific recall information.
Long-term reliability is generally excellent for these trucks, provided regular and diligent maintenance schedules are followed. However, the complexity of diesel emissions systems and the sheer size and cost of heavy-duty components mean that when repairs are needed, they can be significantly more expensive than for lighter-duty vehicles.

How long will the 2021 Ford F-350 Super Duty last?
With diligent maintenance, a 2021 Ford F-350 Super Duty can easily achieve 200,000 to 300,000 miles, with many diesel examples exceeding that mark, especially in commercial fleets. It's not uncommon for these trucks to remain in service for 15-20 years. Their robust chassis, heavy-duty powertrains, and oversized components are designed for long-term durability under strenuous conditions.
However, long-term weaknesses can emerge. Suspension components like bushings, ball joints, and shocks will naturally wear faster under consistent heavy loads, requiring replacement. Diesel emissions systems (DPF, DEF) can become costly maintenance items over time. Rust can also be a significant concern in regions with harsh winters or salty environments, affecting body panels, frame, and undercarriage components. Interior wear, especially on lower trims, might become noticeable after many years of use.

How Does the 2021 Ford F-350 Super Duty Compare to Other Pickup Truck?
The 2021 Ford F-350 Super Duty competes intensely with the Ram 3500 and the Chevrolet Silverado/GMC Sierra 3500HD, forming the "Big Three" of heavy-duty trucks.
In terms of performance, the F-350's 6.7L Power Stroke diesel with 1,050 lb-ft of torque is class-leading for conventional towing and highly competitive for 5th-wheel/gooseneck, often offering the highest maximum towing capacities. The 7.3L "Godzilla" gas V8 is also a strong performer, surpassing rivals' standard gas options. The Ram 3500, with its High-Output Cummins diesel, also boasts immense torque (up to 1,075 lb-ft for 2021) and impressive towing. GM's 3500HD offers the reliable Duramax diesel (910 lb-ft) and a capable gas V8.
Regarding features, Ford's SYNC 3/4 infotainment and the intuitive Pro Trailer Backup Assist are strong points. However, the Ram 3500 often leads in interior luxury, ride comfort (especially with optional air suspension), and infotainment with its Uconnect system and large screen options. GM's 3500HD counters with innovative camera systems, including up to 15 views, making trailering even easier.
Reliability is a strong suit for all three. Ford's Power Stroke has a proven track record, as do the Cummins in Ram and the Duramax in GM. All are built for heavy-duty work and generally exhibit excellent long-term durability, though specific diesel emissions system issues can arise across all brands.
