The Ford Super Duty (also known as the Ford F-Series Super Duty) is a series of heavy-duty pickup trucks produced by the Ford Motor Company since the 1999 model year. Slotted above the consumer-oriented Ford F-150, the Super Duty trucks are an expansion of the Ford F-Series range, from F-250 to the F-600. The F-250 through F-450 are offered as pickup trucks, while the F-350 through F-600 are offered as chassis cabs.

Rather than adapting the lighter-duty F-150 truck for heavier use, Super Duty trucks have been designed as a dedicated variant of the Ford F-Series. The heavier-duty chassis components allow for heavier payloads and towing capabilities. With a GVWR over 8,500 lb (3,900 kg), Super Duty pickups are Class 2 and 3 trucks, while chassis-cab trucks are offered in Classes 3, 4, 5, and 6. The model line also offers Ford Power Stroke V8 diesel engines as an option.

Ford also offers a medium-duty version of the F-Series (F-650 and F-750), which is sometimes branded as the Super Duty, but is another chassis variant. The Super Duty pickup truck also served as the basis for the Ford Excursion full-sized SUV.

The Super Duty trucks and chassis-cabs are assembled at the Kentucky Truck Plant in Louisville, Kentucky, and at Ohio Assembly in Avon Lake, Ohio. Prior to 2016, medium-duty trucks were assembled in Mexico under the Blue Diamond Truck joint venture with Navistar International.

Common 2021 Ford F-550 sd problems

Based on the search results, the following are common problems with the Ford F-550 SD 2021, as reported by owners:

Radiator leaks: The earliest models of the 6.7 Powerstroke diesel engine, which is used in the F-550 SD, often developed radiator leaks. The severity of these leaks varies, and they are less common in later model years. The inlet fitting design on the turbo coolant system sometimes led to leaks, particularly in 2011-2016 models. Additionally, the radiator, water pump, engine oil cooler T-line, and radiator hose O-ring may also be sources of leaks.

Glow plug problems: In the engine's earliest models, particularly the 2011 trucks, the tips from the glow plug may become separated, making it difficult to start up the engine. In later model years, glow plug problems often occurred as a side-effect of exhaust valve failure.

Vacuum pump gasket leaks: Gen 1 models sometimes sprung leaks in the vacuum pump gasket, which was typically caused by loose bolts. Tightening the bolts and replacing the gasket can mitigate the issue.

NOx sensors and emission control: Ford created the Custom Satisfaction Program 12B33 to allow owners to have the NOx sensors checked and replaced, and to provide an upgrade for emission control, particularly in the 2011 and 2012 model years.

Turbo failures: The ceramic ball bearings, especially the ones in the 2011 and 2012 model years, sometimes caused costly turbo failures. Ford eventually switched to steel ball bearings, which resulted in fewer problems.

EGT sensor failure: Vehicles in the 2012 model year sometimes experienced EGT sensor failure, particularly in emergency vehicles equipped with an ambulance package. Faulty EGT sensors may activate "stop safely now" warnings.

EGR cooler flow issues: Common problems in 2015-2019 6.7 Powerstroke engines include issues with the EGR cooler flow, the fan clutch, and the crankshaft damper.

These problems are primarily related to the engine and drivetrain of the Ford F-550 SD 2021. It is important to note that these issues are based on owner complaints and not all vehicles may experience these problems. Additionally, Ford has taken steps to address many of these issues through recalls, service campaigns, and engine improvements.

Date Of Incident: 2021-09-02
Fire: 1
VIN: 1FD0W5HT3ME
Components: ENGINE AND ENGINE COOLING,ENGINE,FUEL/PROPULSION SYSTEM
Summary: While driving down the road at approximately 45 mph, under normal conditions, with no warning indicators the low fuel pressure light came on. When the driver stopped the vehicle he lost all power and observed smoke emanating from the underside and hood of the vehicle. Prior to him exiting the vehicle he observed flames shooting out from under the console towards his feet. Upon exiting the vehicle I saw flames under the hood of the vehicle and utilized his supplied fire extinguisher to attempt to put the fire out. This was futile and to our benefit he had a pressure washer and 119 gallons of water that he was able to put into action to subdue the fire. Noting that the drivers side front fender melted off and a hole melted in the drivers side hood from the fire. The entire engine compartment was burned as well as melted components and plastic in the passenger compartment of the vehicle from the fire.
