The Best Years For Lexus Gx470 And Some To Avoid

The Lexus GX470, a luxury SUV known for its reliability, off-road capability, and comfortable ride, has gained a loyal following over the years. Choosing the right model year can significantly impact your ownership experience, affecting everything from maintenance costs to available features. This guide dives deep into the best and worst years of the GX470, helping you make an informed decision.

The Lexus GX470 offers a unique blend of luxury and ruggedness, making it a popular choice for those seeking a dependable SUV. However, not all model years are created equal. Certain years boast improvements in reliability, features, or addressed previous issues, while others may be more prone to specific problems.

Detailed Explanations

2003-2004: Initial Years; Proven 4.7L V8; Generally Reliable.

The 2003 and 2004 GX470 models represent the initial launch of this luxury SUV. They are equipped with the robust and dependable 4.7-liter V8 engine, known for its longevity and smooth power delivery. These early models are generally considered reliable, making them attractive options for budget-conscious buyers. However, given their age, expect higher mileage and potential wear and tear on components like suspension bushings and interior trim. Technology is also dated compared to later models.

Potential Drawbacks: Potential for higher mileage; older technology; early years may have more wear and tear.

Because these are the oldest models, they are likely to have accumulated significant mileage. This increases the possibility of needing repairs or replacements of wear items like brakes, tires, and suspension components. Furthermore, the technology features are outdated compared to newer vehicles. Expect a less sophisticated navigation system, no Bluetooth audio streaming (though Bluetooth for phone calls may be available on some), and fewer driver-assistance technologies.

2005-2006: Minor Cosmetic Updates; Improved Interior Materials; Navigation System Refinements.

The 2005 and 2006 GX470 models received minor cosmetic updates, including subtle changes to the exterior and interior. These years also saw improvements in the quality of interior materials, making for a more luxurious feel. The navigation system was also refined, offering improved functionality and user interface compared to the initial years. These subtle enhancements make them a slightly more desirable choice than the 2003-2004 models.

Potential Drawbacks: Air suspension can be prone to failure (especially at this age); some reports of secondary air injection pump issues.

A common issue with GX470 models equipped with air suspension, particularly those from these years, is the potential for air suspension failure. The air struts can leak, and the compressor can wear out, leading to a sagging rear end and reduced ride comfort. Replacing the air suspension with traditional coil springs is a common workaround, but it eliminates the self-leveling feature. Some owners also report issues with the secondary air injection pump, which can cause a check engine light and require costly repairs.

2007-2009: Significant Facelift in 2007: Updated Styling, Improved Safety Features (side airbags standard), enhanced navigation.

The 2007 model year marked a significant facelift for the GX470. The exterior received updated styling, including a redesigned front grille, headlights, and taillights. More importantly, side airbags became standard equipment, enhancing passenger safety. The navigation system was also significantly improved, offering a more modern interface and features. These changes make the 2007-2009 models a more desirable option for those seeking a more contemporary look and enhanced safety.

Potential Drawbacks: Air suspension continues to be a potential issue; fuel economy remains unchanged.

While the 2007-2009 models offer significant improvements, the air suspension remains a potential source of trouble. Owners should carefully inspect the air suspension system for signs of leaks or compressor wear. Fuel economy also remained unchanged from previous years, which is a consideration for those concerned about gas mileage.

2009 (Late): Introduction of KDSS (Kinetic Dynamic Suspension System) as an option. Improved off-road articulation.

Late in the 2009 model year, Lexus introduced the Kinetic Dynamic Suspension System (KDSS) as an option. KDSS is designed to improve off-road articulation by hydraulically disconnecting the stabilizer bars, allowing for greater wheel travel. This system enhances the GX470's already impressive off-road capabilities. For those who plan to use their GX470 for serious off-roading, finding a model equipped with KDSS is highly recommended.

Potential Drawbacks: KDSS can add complexity and potential repair costs; finding a model with KDSS requires specific searching.

While KDSS improves off-road performance, it also adds complexity to the suspension system. This increased complexity can lead to higher repair costs if the system malfunctions. Furthermore, finding a GX470 equipped with KDSS requires specific searching, as it was an optional feature and not all models were equipped with it.
