Specs side by side
What owners say
GX
Overall
Sentiment is sharply divided by generation. The previous-generation GX 460 (model years up to 2023) is overwhelmingly praised for its legendary reliability, proven V8 powertrain, comfortable and durable luxury, and high long-term value. Owner feedback describes it as a "bulletproof," over-engineered vehicle that benefits from decades of refinement, with a 10-year cost of repairs reportedly half that of competitors.
Best version to buy
For the GX 460 generation, the final model year (2023) is specifically highlighted as the "one to have" due to receiving the latest updates and a newer infotainment system with Apple CarPlay/Android Auto. The Luxury trim is highly recommended for its adjustable ride control (Comfort/Sport settings), which owners find invaluable for tuning ride quality on different road surfaces.
Known issues
- ⚠**GX 550 (2024+):** Major engine recall (V35A-FTS twin-turbo V6): Safety recall for machining debris causing potential bearing failure and catastrophic engine seizure. Linked to broader issues with Toyota/Lexus's new turbo engines.
- ⚠**GX 460 (Pre-2024):** KDSS system leaks: Failure of the Kinetic Dynamic Suspension System front piston, leading to expensive repairs ($4,000+). Frequency: recurrent.
Armada
Overall
Mixed to positive sentiment, heavily dependent on generation and powertrain. The V8-powered generations (approximately 2004-2024) are widely regarded as reliable, capable, and offering exceptional value on the used market due to high depreciation. Owners praise the proven 5.6L V8 engine, conventional 7-speed automatic transmission (not a CVT), comfortable ride, strong towing capability, and robust build quality, particularly for models built in Japan (post-2017).
Best version to buy
For V8 models (pre-2025), the consensus favors the post-2017 generation (Y62) which switched to the global Patrol platform and Japanese manufacturing, noted for improved build quality and refinement. The Pro-4X trim is specifically recommended for its added capability (locking rear differential, adaptive suspension).
Known issues
- ⚠Poor fuel economy: Real-world combined mileage often reported as 12-16 MPG, lower than EPA estimates, and a frequent point of criticism. Frequency: very frequent.
- ⚠Air suspension failures: Self-leveling air shocks noted to be prone to leaking over time, particularly in older/higher-mileage examples. Frequency: recurrent.
- ⚠Transmission weakness under heavy towing: The 7-speed automatic can be a weak point if subjected to frequent, very heavy towing without proper maintenance (e.g., fluid changes). Frequency: recurrent.
