How the GX 460 compares to the 2024 GX
With the 2024 GX, buyers gain a higher-output engine and improved performance, while the GX 460 remains a viable used option with a classic V8 sound and established reliability. If you’re shopping, verify the exact model year to confirm the engine and horsepower you’re getting.
Summary
The Lexus GX 460’s V8 produces 301 horsepower and 329 lb-ft of torque, a figure consistent across its production years.

What is the difference between Lexus GX 460 and TX 350?
The main difference is that the Lexus TX is a comfortable, family-focused, on-road luxury crossover, while the GX is a rugged, body-on-frame SUV designed for off-road capability. The TX offers more interior space for passengers and cargo, better fuel economy, and a more agile on-road driving experience. The GX, however, has superior off-road features, higher towing capacity, and a more powerful engine option.

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.
Is the Lexus GX 460 fast?
The 2021 GX 460 can go from 0-60mph in 7.8 seconds. A six-speed Electronically Controlled Transmission w/ intelligence (ECT-i) is able to easily cling to curves and go through the gears, enabling a fun drive.
