Summary

The 2016 Lexus GX 460 is a generally reliable vehicle, but owners should be aware of potential issues with the air suspension, KDSS system, valve cover leaks, and infotainment system. Frame rust is also a concern, especially in areas with road salt usage. While some repairs can be costly, the GX 460’s overall dependability and build quality often outweigh these potential issues. The severity of the issues can range from minor inconveniences like infotainment glitches to more serious problems like air suspension failure. Repair costs vary accordingly, with suspension and engine-related issues potentially costing several thousand dollars to resolve.
