Within that volume, owners reported 2 crashes, 5 fires, 5 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2021 F-350 is fuel system, diesel with 19 filings, followed by engine (12) and unknown or other (10). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 177 investigation files overlapping the 2021 F-350, and 8 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

Cold side intercooler boost tube cracked due to constant vibration impact from coolant overflow hose routed directly above and on top of it. Part and vehicle is available for inspection. The split in the boost hose caused me to loose power while attempting to merge onto a road, almost being hit by another vehicle. After research there are multiple other instances of complaints of the same thing happening to others and multiple aftermarket manufacturers producing replacement and upgraded parts with references and warnings of the same thing happening for the last 10 years. No warning lamps or symptoms prior to failure. After failure no warning lamps but could hear an audible hiss. The vehicle has not yet been inspected by the dealer or police. I was told by their parts people it is a regular failure and the part costs typically around $200 and they only sold it as a full part and not just the rubber replacement hose althought they are separate parts connected with hose clamps.

Back up camera screen goes blue when put in reverse. Then after 20 seconds says camera unavailable see dealer. I had dealer repair with a software reset. Worked for about 2 weeks then same symptoms. Noticed Ford has a recall for the same symptoms on other vehicles but for some reason F-350s are not a part of it. Would suspect the truck uses the same camera system as the other ford vehilces under the recall. Ford needs to step up and cover the F-350s

Upon starting the vehicle I get precollision not available warning light and hill decent control fault hill assist warning. Service steering and antilock brake brake fault lights. The dealer has looked at it but they said can not duplicate it. The problem is when I am towing my fifth wheel trailer and this happens it shuts down the brake controller for the fifth wheel and itâs VERY hard to stop the truck and trailer
