What years to avoid GX 460?
The main Lexus GX 460 years to avoid are 2010–2013 due to potential issues like engine oil leaks (valley plate leak), as well as the 2010 model specifically, which had a temporary sales suspension after a rollover risk was identified during sharp turns. Later models, especially 2016 and 2017, may be more prone to oil leaks as well, though not as critically as the earlier years.
Years to be cautious about
- 2010–2013: These early models are more frequently cited for potential problems, such as the valley plate coolant leak, which can be expensive to repair.
- 2016 and 2017: These years have been noted by some owners as having a higher likelihood of oil leaks.
Model years generally considered more reliable
- 2014 and later: These models reportedly have a different, less leak-prone head gasket.
- 2021 and 2022: These years are specifically highlighted as being very reliable.
Other potential issues to consider with any model year
- Secondary Air Injection System: Problems with this system can be costly to repair.
- Suspension: Models with the optional AHC (Adjustable Height Control) or KDSS (Kinetic Dynamic Suspension System) can experience issues, though Lexus has issued a TSB (Technical Service Bulletin) to address a leaning issue in some earlier KDSS vehicles.
- Rust: In areas where roads are salted, rust can be a concern, especially on models driven in the North.
- Maintenance: Regular and consistent fluid changes, especially transmission fluid, are crucial to the longevity of the vehicle.
