Top Risk Areas
The systems that tend to fail first on the 2006 Lexus LX, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
The complex hydraulic AHC system, including height sensors, accumulators, pump, and struts, can develop leaks or outright failures leading to sagging, erratic ride height, or a 'frozen' suspension. This is the most common and costly majo…
