What is the best year of the Lexus LX 570?

The best year for a Lexus LX 570 depends on your priorities, but the 2013-2015 model years are often cited for a good balance of reliability and features, while 2016-2021 models offer the newer eight-speed transmission and enhanced safety features. If you prioritize the most modern features and safety systems, a later model is ideal, whereas earlier models may be less expensive and have a more robust feel to some enthusiasts. All LX 570s are known for durability and longevity, especially if well-maintained.
 
2013-2015 

• Pros: Considered by some as a sweet spot for reliability, with a 6-speed transmission that some may find simpler, and a comfortable ride. The styling was revised in 2013, introducing the spindle grille.
• Cons: Lacks the 8-speed transmission and the latest advanced safety features of later models. 

2016-2017 

• Pros: Introduced the 8-speed automatic transmission, improving fuel economy slightly. The 2017 model year made Lexus Safety System Plus standard, adding features like forward-collision mitigation and adaptive cruise control. 
• Cons: The 8-speed transmission may be more complex than the older 6-speed. 

2018-2021

• Pros: These models are essentially the same as the 2016-2017 in terms of powertrain and major features, offering the benefits of the 8-speed transmission and standard safety tech. They are the final years before a redesign. 
• Cons: Potentially higher price points compared to earlier models.

Overall considerations

• Reliability: All LX 570s (from 2008-2021) are based on the highly reliable Toyota Land Cruiser platform and are known for their extreme durability and longevity with proper maintenance, even at high mileage. 
• Maintenance: Regardless of the year, regular maintenance, particularly the 30,000-mile service and ensuring the hydraulic suspension fluid is flushed, is crucial for long-term reliability. 
• Technology: Features like Apple CarPlay were not standard, so you may need to budget for an aftermarket upgrade to get that functionality.
