Specs side by side
What owners say
QX56
Overall
Mixed sentiment with a clear generational divide. The first-generation QX56 (2004-2010) is generally viewed as a robust, reliable, and capable full-size SUV with a "bulletproof" V8 powertrain, offering significant value on the used market due to high depreciation. Long-term owner reports praise its durability, with multiple examples cited reaching 200,000 to 350,000 miles with basic maintenance.
Best version to buy
Insufficient owner data available to designate a specific model year or trim as "best." Feedback is primarily divided by generation, with implicit favor towards the 2005-2010 first-generation models for their perceived mechanical robustness and away from the 2011-2013 models due to the timing chain and catalytic converter issues. One owner noted the Infiniti could be had with load-leveling rear air suspension, but no trim level consensus exists.
Known issues
- Premature catalytic converter failure: Very expensive repair ($1,700-$6,000 for parts), often occurs shortly after warranty expiration, can cause misfires and running rich. Frequency: very frequent.
- Timing chain system failure: Causes loud whistling/whining noise, loss of power, can lead to catastrophic engine damage with metal in oil; repair costs extremely high ($4,000-$13,500). Frequency: very frequent.
- Excessive fuel consumption: Real-world mileage reported as low as 11-12 MPG. Frequency: very frequent.
Sequoia
Overall
Sentiment is sharply divided by generation. For the previous generation (approximately 2008-2022, referred to as Gen 2), sentiment is overwhelmingly positive, characterized by extremely high praise for legendary reliability, durability, and practicality. Owners report vehicles with over 200,000 miles requiring only routine maintenance, describing them as "built like a tank" and capable of lasting for decades.
Best version to buy
For the previous generation (Gen 2), the SR5 base trim in 4x4 with leather seats is frequently recommended as the best value, offering core capability without expensive gadgets that could break. The Limited and Platinum trims are acknowledged as feature upgrades but are often considered less essential.
Known issues
- **Current Generation (2023+):** *Engine Failure (Machining Debris): Catastrophic failure due to metal shavings left in engine block during manufacturing, leading to spun main bearings. Subject of a large, expanding recall.
- **Previous Generation (approx. 2008-2022):** *Frame Rust: Box frames rust from the inside out, potentially leading to structural failure. The most critical item to inspect before purchase. Frequency: very frequent.
