Best Model Years
2013-2017 (facelifted XF40 generation)
Years to Avoid
None stand out as significantly problematic within the XF40 generation; however, early 4th generation models (2007-2009) had some valve spring recall issues, which should have been resolved by now.

Top Risk Areas
The systems that tend to fail first on the 2015 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.
The optional air suspension can develop leaks or compressor failures over time, leading to uneven ride height, degraded ride quality, or complete system collapse. This is a common luxury car issue, not unique to Lexus.
Like many heavy luxury sedans, the front lower control arm bushings can wear out, leading to clunking noises over bumps, premature tire wear, and a looser steering feel. This is a wear item, not a defect.
While generally robust, some owners report occasional freezing or slow response from the Lexus Remote Touch controller and navigation unit. These are often software-related and less common than hardware failures.

The mileage windows when the 2015 Lexus LS most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Low Risk Zone

Maintenance Zone
This is a key service interval for fluid changes (transmission, differential, coolant), spark plugs, and checking belts. Address any wear items like control arm bushings if signs emerge.
Elevated Risk Zone
Wear items become more prevalent. This is where air suspension components or major suspension bushings may start to show signs of age. Budget for proactive replacement of some components.
