Top Risk Areas
The systems that tend to fail first on the 2003 Lexus LS, 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.
If equipped, the air struts (shock absorbers) and air compressor are known to fail over time, leading to a sagging ride or inability to maintain ride height. This is a common age-related wear item.
The touch-screen display can suffer from pixelation, dimming, or complete failure, making the navigation and audio controls difficult or impossible to use. This is a prevalent issue in the XF30 generation.
Over time, the power steering pump can develop leaks or outright failure, leading to a loss of power assist and potential noise. This is often an age-related seal degradation issue.
