Each tile shows the median mileage at which that model year’s failures were reported. The 2006 reports latest and the 2005 earliest, but part of that gap is age: the 2005 has had 1 more year on the road to accumulate mileage.

Owners filed 1,525 complaints with NHTSA about the 2003–2006 Ford Expedition; the engine and its cooling system leads with 18% of them, and half of the 1,240 that record an odometer reading came by 79,000 miles. A count like this can’t rate reliability on its own: NHTSA records what owners chose to report, not how many of each car were sold.
Failures are spread across the mileage range, with the middle half between 42,000 and 113,000 miles.

How many miles does a 2003–2006 Ford Expedition last?
Complaint records can’t measure how long a car lasts; they show when reported failures happened. On the 2003–2006 Ford Expedition, half of the 1,240 complaints that record an odometer reading were filed by 79,000 miles and 90% by 155,000 miles.
139 reports came in past 150,000 miles and 34 past 200,000 — each one proof that an Expedition reached that mileage, not that it failed there.

System by system, in words
Complaints about this generation are not spread evenly across the vehicle, and the systems that generate the most of them do not all fail at the same point in a car's life. The median failure across all systems here is 79,000 miles; the figures below show which parts of the car run ahead of that and which run behind.
The engine and its cooling system accounts for 18.0% of complaints (275 reports, 244 of them with a mileage figure), with a median of 81,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 60,000 and 101,000 miles.
The electrical system accounts for 16.3% of complaints (248 reports, 205 of them with a mileage figure), with a median of 83,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 55,000 and 130,000 miles.
The engine accounts for 14.2% of complaints (217 reports, 191 of them with a mileage figure), and it fails late — a median of 120,000 miles, considerably beyond the vehicle's overall median. That pattern is consistent with normal service life rather than a defect, though it matters for anyone buying an example already near that mileage. The middle half of these reports falls between 90,000 and 150,000 miles.
The transmission and driveline accounts for 9.4% of complaints (143 reports, 116 of them with a mileage figure), with a median of 63,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 18,000 and 107,000 miles.
Throttle and speed control accounts for 8.9% of complaints (136 reports, 124 of them with a mileage figure), with a median of 75,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 50,000 and 92,000 miles.
The airbag system accounts for 8.5% of complaints (129 reports, 101 of them with a mileage figure), with a median of 85,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 51,000 and 128,000 miles.
Known problems with the 2003–2006 Expedition
Engine 2005–2006
Three-valve 5.4L two-piece spark plug design: the lower ground-shield section seizes in the head from carbon buildup and snaps off during removal, requiring specialized extraction and often head damage.
Engine 2005–2006
Variable cam timing phaser rattle. Oil-fed cam phasers lose control authority when hot idle oil pressure or oil condition degrades, producing a diesel-like rattle at cold start and idle, and can progress to timing chain and cam damage.
Suspension
Rear air suspension air spring and compressor failure (independent rear suspension introduced this generation).
Before you buy a 2003–2006 Expedition: the 3-minute check
Generated from 1,240 mileage-tagged complaints, 3 recall campaigns, 3 documented problem areas. Print this page — the checklist survives print.
- Run the VIN at nhtsa.gov/recalls. 3 campaigns cover this generation; an open recall is a free repair you can make the seller's problem.
- Check engine on 2005–2006 cars. Three-valve 5.4L two-piece spark plug design: the lower ground-shield section seizes in the head from carbon buildup and snaps off during removal, requiring specialized extraction and often head damage.

- Check suspension. Rear air suspension air spring and compressor failure (independent rear suspension introduced this generation).
- End with a pre-purchase inspection of this car. Aggregate data describes the population; the example in front of you has its own history.
For a buyer, failures on this generation are spread rather than concentrated: the middle half falls between 42,000 and 113,000 miles, with a median of 79,000. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.
On inspection, the engine and its cooling system and the electrical system are where this generation's reports concentrate, so those are the areas worth a specific look. The engine and its cooling system in particular shows a median failure mileage of 81,000, which gives a concrete number to compare against the odometer of any car you are considering.
None of this is a substitute for a pre-purchase inspection on the individual car. Aggregate patterns describe a population; the example in front of you has its own history.

2003–2006 Ford Expedition recalls (3)
NHTSA records 3 recall campaigns covering vehicles in this generation. A recall means the manufacturer or the regulator concluded there was a safety defect or a standard was not met, and that a free remedy is owed to owners — including second and later owners.
Recall status is specific to the individual vehicle, not the model. Checking a VIN against NHTSA's lookup is free and takes under a minute, and it is the only way to know whether a particular car has had the work done.

The defect. On certain trucks, passenger cars and sport utility vehicles, the windshield wiper motor may have been produced without grease being applied to the output shaft gear.
What can happen. After a period of continuous use on the high speed setting, lack of grease on the output shaft gear may cause the gear to distort or fracture during operation resulting in a loss of wiper function.…
The free fix. Dealers will inspect the wiper motor for the presence of grease and grease the wiper motor gears if necessary. The recall began on november 22, 2005. Owners may contact Ford at 1-800-392-3673 or…

The defect. On certain sport utility vehicles, the front and rear tires on the driver's side of affected vehicles may have been damaged at the center tread during production.
What can happen. Over time, the damage may be sufficient to allow belt corrosion ultimately leading to a tread separation, which could result in a crash.

Crashes, fires and injuries owners reported
What owners reported alongside the failure itself, out of 1,525 complaints against this generation:
- Crashes
- 144 (9.4%)
- Fires
- 63
- Injury reports
- 102
- Fatality reports
- 6
These flags are self-reported by complainants and unverified by NHTSA; one report can carry several flags, so the counts overlap and do not sum to a total. They are not adjusted for how many of these vehicles are on the road. No chart is drawn here on purpose: overlapping counts spanning very different magnitudes cannot be honestly encoded as lengths.
Expedition problems by model year
The 2003 drew the most complaints of this generation, 615, most of them about the engine and its cooling system, and the 2004 the fewest, 296. A typical year drew about 307.
That makes the 2003 stand out at roughly 2.0 times a typical year. A count like this follows how many cars of each year were sold and how long they have been on the road as much as how often they failed, so it is not by itself evidence of a worse year; what each year's reports name, in its card and row, is the useful part.
| Year | Complaints | With mileage | Median miles | Most reported | Recalls |
|---|---|---|---|---|---|
| 2003 | 615 | 463 | 80,000 | Engine and its cooling system (127) | 1 |
