When does it fail?
Of the 16 suspension complaints filed for the 2006 Lincoln Navigator, here's the actual mileage breakdown — failures cluster heaviest at 0-25,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
Suspension accounts for 27% of all owner complaints filed against this vehicle, across 5 categories tracked.
No new NHTSA suspension complaint has been filed on this vehicle in over 14 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering suspension on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
The 2006 Navigator's air suspension system is the core complaint across these 16 reports. Owners describe the suspension repeatedly dropping out, losing pressure, and bottoming the vehicle—sometimes mid-drive, sometimes stranding them. One owner was in the shop 7–10 times over two years for the same issue despite replacing the control module three times, ride height sensors, and an air compressor. Another replaced the compressor for $900 and got one week of function before the problem returned.
Cold weather triggers a separate but related failure: violent bouncing that makes the vehicle unsafe on highways. Owners in Arizona and Michigan report this seasonal pattern; several mention it's a known internet issue and suspect faulty O-rings. Dealers have replaced airbags, O-rings, and compressors without stopping the bounces when temperatures drop.
Diagnostically, dealers and Ford field reps report computer systems show nothing wrong—a recurring dead-end. One owner alleges a dealer claimed Ford weighed recall costs against injury risk and declined action.
Two owners also report motorized running board hardware separating mid-drive—bolts breaking, rust, brackets failing—creating road-hazard risk.
One report notes an abnormal cranking noise from the front end at low speeds that a dealer couldn't diagnose, and another flags a suspension warning on the instrument cluster during highway driving.

Failure modes owners describe
Air suspension collapse and loss of ride height
The air suspension system loses pressure and drops the vehicle to the ground or near-ground level, making the vehicle undrivable or extremely difficult to steer and control.
When: Chronic issue occurring repeatedly; reported as early as 2010 for some owners; triggered or worsened in cold weather for several owners
Symptoms owners cite: Vehicle bottoms out or drops suddenly; Unable to steer or make sharp turns; Vehicle breaks down while driving; Loss of suspension height detected
Repairs/costs cited: Owners report repeated replacement of suspension airbags, compressors, control modules, and ride height sensors; costs cited include $900 for air compressor replacement, $700 temporary repair, and cumulative bills exceeding $4,000; repairs failed to resolve the issue—failures recurred within days to months
Recalls/TSBs owners mention: Ford field representative inspected vehicles and found no fault; dealers reported computer diagnostics showed nothing wrong; no recall issued despite multiple shop visits (7–10 times for some owners); one dealer banned a customer from returning for further service
Cold-weather air suspension malfunction (bouncing)
The air suspension system fails to function in cold temperatures, causing the vehicle to bounce or oscillate violently, making it unsafe to drive, especially on highways.
When: Occurs specifically when temperatures drop below a certain threshold; reported as consistent seasonal pattern during winter or cold-weather trips
Symptoms owners cite: Uncontrollable bouncing while driving; Violent shaking; Suspension bottoms out in cold weather; Traction control fails when suspension is out
Repairs/costs cited: Owners cite replacement of O-rings, airbags, and compressors without lasting effect; one owner had all suspension parts changed but bouncing resumed on first cold day; another owner replaced compressor for $900 with temporary success
Recalls/TSBs owners mention: No recall; dealers unable to diagnose under cold-weather conditions; one owner reports being told that Ford weighed the cost of admitting the issue against the cost of recalls
Abnormal cranking noise from front end at low speeds
The front end produces abnormal cranking or popping noises when accelerating or braking at low speeds.
When: At approximately 36,000 miles; occurs during acceleration or braking at low speeds (around 10 mph)
Symptoms owners cite: Abnormal cranking noise from front end; Noise occurs with accelerator pressure; Noise occurs with brake application; Occurs at low speeds
Recalls/TSBs owners mention: Dealer unable to diagnose; vehicle not repaired
Running board hardware failure and rust
The aluminum mounting brackets or bolts securing the motorized running boards fail or break without warning, causing the running boards to detach or hang away from the vehicle. Rust develops on running board bolts and components.
When: No specific mileage cited; occurs during normal driving (at traffic light, low-speed turn)
Symptoms owners cite: Running board detaches or hangs completely away from vehicle; Bolts break off or come loose; Rust visible on running board and bolts; Running board is cracked
Repairs/costs cited: Owner had to manually push the running board back in place and drive slowly to prevent it from falling and striking another vehicle
Suspension check warning notification
Dashboard notification alerts driver to check suspension system while driving at highway speeds.
When: While driving on freeway at approximately 65 mph
Symptoms owners cite: Check suspension notification appears on screen
