How many miles does a 2003–2006 Lincoln Navigator last?
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 (why that is not a lifespan).
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.

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.
