On the 2011 Ford F-450, the failure owners report most often is other engine problem, with 4 reports on file. Across every failure mode on this year, half the dated reports were filed before 80,000 miles.
What breaks on the 2011 Ford F-450
Owners have reported 7 named failure modes on the 2011 Ford F-450, and the three most-reported carry 58% of everything filed.
Other engine problem leads with 4 reports and about 8.1 per 1,000 vehicles.
Other steering problem follows with 2 reports, median 95,000 miles.
Complete engine failure or seizure follows with 1 report, median 70,000 miles. 1 of those report mention a fire.
By system, the reports fall mostly into engine (5), steering (3) and transmission (1).
At what mileage it happens
11 of the reports on the 2011 Ford F-450 came with an odometer reading, and half of those were filed before 80,000 miles.
Cumulatively, 73% by 100,000 miles of the dated reports had been filed.
The busiest stretch is between 50,000 and 60,000 miles, which alone holds 27% of the dated reports.
0% of the dated reports were filed below 36,000 miles, so this is mostly a story about older, higher-mileage cars.

How bad it is when it goes
Across the named modes, 2 a fire. Those are the words owners used in their own complaints, and NHTSA does not verify them, but they are the closest thing in this data to a measure of what a failure actually did.
The average severity weight across every report on this year is 5.17, where a stalled engine or a failed airbag weighs many times more than a rattling trim panel, and a figure this high means the reports are dominated by failures with safety consequences rather than annoyances. The weighting is set out in full on the methodology page.
What the top failures cost to put right, as editorial estimates for an independent US shop rather than figures from NHTSA: other engine problem at $300–$4,000, other steering problem at $350–$2,400, complete engine failure or seizure at $4,500–$12,000 and loss of power steering at $600–$2,800. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.
50% of the reports on this year sit in the engine, transmission, drivetrain or cooling systems — the four where a repair bill is usually four figures, so more than half of what owners complained about here is expensive.

Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.
How often, against how many were built
Scaled by an estimate of how many of these cars exist, the 2011 Ford F-450 draws about 24 per 1,000 vehicles, which puts it in the 95th percentile of complaint rates among 2011 vehicles we can rate.
That denominator is the weakest number on the page and it is fair to say so plainly. Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound.
The working figure is 491 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2011 vehicles, which is what the risk score uses, is far more robust than the rate itself.

Other engine problem
Engine logo light came on; then red sign came on " stop safely now". I pulled to the shoulder and the engine stopped. I waited 30 minutes or so and the engine started again. I drove starting and stopping to a ford dealer in clarion, pa. Slept in the truck all night and the next morning [xxx] ran the computer and his conclusion was the number 8 cylinder injector was bad and that causes the heat sensors to malfunction. He didn't have the part but suggested running it until it cuts out, let it cool then run it again. Well after about 70 miles it stopped for good. I then called up montross ford, and they had the injector so I bought it thinking next I'll find the mechanic, on a saturday afternoon I was wrong. Next I looked up recalls and I found a recall for faulty heat sensors, that recall was for the same time period as my truck was made. I am now sitting on the side of rt. 76 with no where to go pulling a 4 car trailer, customers upset and my last hope is ford motor co. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

Complete engine failure or seizure
While driving at 45 MPH on a highway the engine blew up. Ford reported the problem was a faulty glow plug which fell into the cylinder causing the connecting rod to break and exit the side of the engine block. Fire ensued but was short lived.
Recalls on the 2011 model year
NHTSA has issued 2 recall campaigns covering the 2011 Ford F-450, affecting an estimated 491 vehicles. A recall is a different kind of evidence from a complaint: it is the regulator and the manufacturer agreeing that something has to be fixed, and the fix is free for as long as the car exists.
The campaigns cover equipment and engine. Whether the work was actually done on the car in front of you is a question only the VIN can answer, and the manufacturer or NHTSA will answer it free.
One caution about reading these together: a recall usually raises the complaint count for the same part, because owners who read about it go and file. The mileages stay informative; the counts get noisy.
EQUIPMENT
3 vehicles 2014-08-13- Defect
- PJ's Truck Bodies & Equipment Co., (PJ's) is recalling certain 2009-2013 Ford F-350, F-450, and F-550 Super Duty chassis modified by PJ's and equipped with certain Muncie Power Products PTO Assemblies. In the affected vehicles, oil may leak from the PTO pressure switch onto a thermal blanket covering the exhaust.
- Consequence
- The leaking oil may soak into the thermal blanket covering the exhaust, which when combined with heat from exhaust, may result in an increased risk of fire.
- Remedy
- PJ's has notified owners and dealers will install a new pressure switch kit that moves the switch away from the exhaust system, free of charge. The recall began on August 28, 2014. Owners may contact PJ's customer service at 1-866-475-8782.
ENGINE
2,951 vehicles 2013-10-30- Defect
- Ford Motor Company (Ford) is recalling certain model year 2011-2012 F-350/450/550 Ambulance Package vehicles manufactured February 22, 2010, through October 19, 2012 and equipped with a 6.7L diesel engine. Due to an exhaust sensor problem, the vehicles may experience loss of power followed by an engine stall.
- Consequence
- An unexpected engine stall increases the risk of a crash. Additionally, if this were to occur when the ambulance is transporting a patient, there is an increased risk of injury to the patient.
- Remedy
- Ford will notify owners, and dealers will replace the exhaust gas temperature sensor, free of charge. The recall began on November 25, 2013. Owners may contact Ford Motor Company Customer Relationship Center at 1-866-436-7332. Ford's recall campaign number is 13S10.
Recall work is free at a franchised dealer regardless of the car's age. Check the VIN at nhtsa.gov/recalls before assuming it was done.
How 2011 compares with the other years
Across the 5 model years of this car that carry enough reports to score, 2020 comes out best at 62 and 2018 worst at 73.
Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.
Shorter is better. Years with too few reports to score are shown without a bar rather than as a zero, because no data is not good news.
The limits of complaint data
12 owner reports; fleet size estimated from this year's own recall paperwork. Every count on this page is therefore a floor: it is the number of owners who went to the trouble of filing with a federal agency, which is a small and self-selected fraction of the owners who had the fault.
Of those 12 reports, 11 carried an odometer reading, so the mileages here describe 92% of the sample rather than all of it. Owners also round: readings pile up on multiples of ten thousand, which is why this site publishes "about 90,000 miles" and not "91,438".
The failure modes are assigned by software reading the owner's own words, which is accurate in bulk and wrong in individual cases. A mode with a handful of reports may contain a misfiled one.
And nothing here predicts what one car will do. These are other people's complaints, filed years apart, on cars maintained by strangers. Read the page as a map of where this model year has previously gone wrong, then have the specific car in front of you inspected.
Questions this page answers
What are the most common problems with the 2011 Ford F-450?
The most-reported failures are other engine problem (4 reports, median 105,000 miles), other steering problem (2 reports, median 95,000 miles) and complete engine failure or seizure (1 report, median 70,000 miles). Counts come from owner complaints filed with NHTSA, which are voluntary, so they show what owners bothered to report rather than every fault that occurred.
Where this comes from. Every figure above is computed from NHTSA owner complaints and recall records for this exact make, model and year. Complaints are voluntary and self-selected, so treat counts as a floor. The methodology page writes out each formula, and the same numbers are available as JSON.
