3 recall campaigns name the 2006: Visibility — windshield wiper/washer; Power train — automatic transmission; Tires — tread/belt. Not every car in a campaign is affected — check the VIN at NHTSA. Recall repairs are free.
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 321 complaints with NHTSA about the 2003–2006 Lincoln Navigator; the suspension leads with 28% of them, and half of the 246 that record an odometer reading came by 69,000 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 25,000 and 102,000 miles.

How many miles does a 2003–2006 Lincoln Navigator last?
Complaint records can’t measure how long a car lasts; they show when reported failures happened. On the 2003–2006 Lincoln Navigator, half of the 246 complaints that record an odometer reading were filed by 69,000 miles and 90% by 140,000 miles.
20 reports came in past 150,000 miles and 3 past 200,000 — each one proof that a Navigator 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 69,000 miles; the figures below show which parts of the car run ahead of that and which run behind.
The suspension accounts for 28.0% of complaints (90 reports, 73 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 40,000 and 103,000 miles.
A single system taking 28.0% of all complaints is a concentration worth noting. It means that for this generation, most of what owners reported came back to one area of the car rather than being distributed across many small faults.
The electrical system accounts for 13.7% of complaints (44 reports, 28 of them with a mileage figure), with a median of 56,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 10,000 and 100,000 miles.
The airbag system accounts for 12.1% of complaints (39 reports, 32 of them with a mileage figure), with a median of 95,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 56,000 and 125,000 miles.
Body structure accounts for 11.8% of complaints (38 reports, 27 of them with a mileage figure), with a median of 55,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 3,000 and 95,000 miles.
The engine and its cooling system accounts for 11.2% of complaints (36 reports, 31 of them with a mileage figure), with a median of 60,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 32,000 and 105,000 miles.
The transmission and driveline accounts for 8.7% of complaints (28 reports, 23 of them with a mileage figure), and it fails early — a median of 35,000 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 3,000 and 74,000 miles.
Known problems with the 2003–2006 Navigator
Air Suspension 2003–2006
Air spring leaks, compressor failure and height-sensor faults continue; complaint volume is highest around MY2004.
Spark Plugs (5.4L 3-Valve) 2005–2006
The 3-valve Triton used a two-piece spark plug whose lower porcelain/shell section seizes in the head and breaks off during removal, turning a routine plug change into head-removal-level work.
Variable Cam Timing / Timing Chain (5.4L 3-Valve) 2005–2006
Cam phaser rattle at cold start and under light load, and timing chain tensioner/guide wear, on the 3-valve 5.4L; aggravated by low or degraded oil.
Before you buy a 2003–2006 Navigator: the 3-minute check
Generated from 246 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 air suspension on 2003–2006 cars. Air spring leaks, compressor failure and height-sensor faults continue; complaint volume is highest around MY2004.
- Check spark plugs (5.4L 3-Valve) on 2005–2006 cars. The 3-valve Triton used a two-piece spark plug whose lower porcelain/shell section seizes in the head and breaks off during removal, turning a routine plug change into head-removal-level work.
- Check variable cam timing / timing chain (5.4L 3-Valve) on 2005–2006 cars. Cam phaser rattle at cold start and under light load, and timing chain tensioner/guide wear, on the 3-valve 5.4L; aggravated by low or degraded oil.
- 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 25,000 and 102,000 miles, with a median of 69,000. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.
On inspection, the suspension and the electrical system are where this generation's reports concentrate, so those are the areas worth a specific look. The electrical system in particular shows a median failure mileage of 56,000, 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 Lincoln Navigator 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.

Crashes, fires and injuries owners reported
What owners reported alongside the failure itself, out of 321 complaints against this generation:
- Crashes
- 19 (5.9%)
- Fires
- 10
- Injury reports
- 24
- Fatality reports
- 1
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.
Navigator problems by model year
The 2003 drew the most complaints of this generation, 127, most of them about the suspension, and the 2005 the fewest, 48. A typical year drew about 73.
The first year of the generation, 2003, drew more complaints than 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.
