Common problems with the 2004 F-550 Super Duty
NHTSA's file holds 49 owner complaints on the 2004 Ford F-550 Super Duty. Owners named the diesel fuel system most often: 21 complaints, and half of the 19 that list a mileage came after 44,000 miles. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Fuel System, Diesel | 21 | 19 | 44,450 |
| Engine And Engine Cooling | 16 | 13 | 35,158 |

Mileage when owners reported a problem with the 2004 F-550 Super Duty
The 39 mileages owners gave run from 38 to 262,257 miles. A quarter are at or under 12,000 miles, half at or under 36,000, three quarters at or under 74,145 and nine in ten at or under 125,000; 5 (13%) came after 100,000 miles, 3 (8%) after 150,000 and 1 (3%) after 200,000.
These mileages say when owners reported a problem, not when a 2004 F-550 Super Duty wears out. NHTSA's file holds only vehicles whose owners complained; one that ran without a problem never appears in it, so it gives no lifespan and no cutoff, and how a vehicle was maintained matters more than any one odometer reading.
Most of these reports came early in the vehicle's life: 34 of the 39 came at or under 100,000 miles, so they say nothing about how many miles a 2004 F-550 Super Duty can cover.
| Measure | Value |
|---|---|
| Lowest mileage listed | 38 miles |
| 25th percentile | 12,000 miles |
| Median (50th percentile) | 36,000 miles |
| 75th percentile | 74,145 miles |
| 90th percentile | 125,000 miles |
| Highest mileage listed | 262,257 miles |
| Complaints after 100,000 miles | 5 (13%) |
| Complaints after 150,000 miles | 3 (8%) |
| Complaints after 200,000 miles | 1 (3%) |
Is the 2004 F-550 Super Duty a good year?
Complaint counts cannot say whether the 2004 is a good or a bad F-550 Super Duty: they rise with how many were sold and how long they have been on the road. They show how the 2004 compares with the other model years in NHTSA's file.
With 49 complaints, the 2004 ranks 3rd of the 12 Ford F-550 Super Duty model years from 1999 to 2021 with 10 or more complaints, counting from the most. The most: the 2000 (72). The fewest: the 2015 (11).
Recent model years have had less time to collect complaints, so their counts are still growing. No year is ranked by mileage here, because a year's median mileage mostly follows its age.
| Model year | Owner complaints | Listing mileage | Median mileage |
|---|---|---|---|
| 1999 F-550 Super Duty | 61 | 23 | 65,000 |
| 2000 F-550 Super Duty | 72 | 28 | 50,000 |
| 2001 F-550 Super Duty | 29 | 7 | Under 10 mileages |
| 2002 F-550 Super Duty | 22 | 15 | 59,000 |

What these figures can and cannot tell you
- Complaints are owners’ reports to NHTSA. NHTSA publishes them without verifying them: a complaint is an allegation, not a defect finding.
- The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
- The make, model and model year are the ones on the complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
- They are not a lifespan study. The file holds only vehicles whose owners reported a problem, so these figures do not say how long a typical 2004 F-550 Super Duty lasts.
- A complaint count rises with how many vehicles were sold and how long they have been on the road, so it is not a rating of the 2004 F-550 Super Duty.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 10 of the 49 complaints on the 2004 Ford F-550 Super Duty give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
- NHTSA name counted: F-550 SD. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only this one.
- Recall-file name matched: F-550 SD.
