What Problems Does the 2006 Lexus GX 470 Have?
While the 2006 Lexus GX 470 is renowned for its exceptional reliability, certain issues are frequently reported as these vehicles age. One of the most common long-term concerns revolves around the rear air suspension system. The air bags (springs) can develop leaks, and the air compressor can fail, leading to sagging rear end or a continuously running compressor. This typically becomes noticeable around 100,000-150,000 miles. Many owners opt to replace the air bags with conventional coil springs for a permanent fix, though this sacrifices the auto-leveling feature.
Another prevalent issue, particularly with the 2UZ-FE V8 engine across various Toyota/Lexus models, is cracked exhaust manifolds. Symptoms include a ticking noise, especially on cold starts, which usually dissipates as the engine warms up. This is primarily an annoyance but can sometimes lead to exhaust leaks.
For vehicles driven in regions with road salt, frame rust is a significant concern. Thorough inspection of the frame is critical before purchase, as severe rust can compromise structural integrity. Similarly, the secondary air injection pump and its associated valves can fail, triggering a check engine light. This is an emissions-related repair that can be costly due to parts and labor.
Another known issue for many Toyota/Lexus models of this era is a cracked dashboard due to sun exposure and material degradation. While cosmetic, it's a common complaint. Finally, the starter motor is known to fail eventually, and its location deep within the engine's "V" under the intake manifold makes it a labor-intensive and expensive repair when it does occur, typically at higher mileages.
Regarding recalls, the 2006 GX 470 has been subject to a few. A notable recall (NHTSA Campaign Number 05V243000) involved certain 2003-2005 GX 470 models for a power steering pressure hose that could leak, potentially causing a fire. Always check the NHTSA website for any open recalls by VIN. Despite these potential issues, with proactive maintenance and addressing these known points, the GX 470 remains a highly durable and dependable vehicle capable of hundreds of thousands of miles.

How long will the 2006 Lexus GX 470 last?
The 2006 Lexus GX 470 is a testament to Toyota's engineering longevity, with many owners reporting average mileage well exceeding 250,000 to 300,000 miles, and numerous examples reaching 400,000+ miles with diligent maintenance. The 4.7L V8 engine and automatic transmission are exceptionally durable, often outlasting the rest of the vehicle. This robust, body-on-frame SUV exhibits remarkable long-term durability. However, weaknesses emerge over time, primarily the rear air suspension system, which can leak or fail, leading to costly repairs. Frame rust is a significant concern in wetter, salt-prone climates and must be thoroughly inspected. Other age-related items include cracking dashboards, exhaust manifold leaks, and eventually, the starter motor requiring replacement. Despite these, with proper fluid changes, rust prevention, and addressing specific wear items, the GX 470 offers decades of reliable service.
What Technology & Safety Features are Included?
The 2006 Lexus GX 470, while not at the cutting edge of modern tech, offered a respectable array of features for its time, focusing on luxury, comfort, and off-road capability.

The 2006 Lexus GX 470 occupies a unique niche, blending luxury with serious off-road capability. When stacked against key rivals from its era, its strengths and weaknesses become clear.
Against European Luxury SUVs (e.g., Land Rover LR3/Discovery 3, Mercedes-Benz ML-Class, BMW X5):
Against Asian Rivals (e.g., Acura MDX, Toyota 4Runner):
Recommendations:
Against European Luxury SUVs (e.g., Land Rover LR3/Discovery 3, Mercedes-Benz ML-Class, BMW X5):
- Performance: The GX 470's 4.7L V8 offers smooth, strong power. While European rivals like the BMW X5 or Mercedes ML might offer more powerful engine options or more car-like, agile on-road handling, the GX 470 excels in off-road prowess and towing capability, often surpassing the X5 and ML. The LR3 is a formidable off-roader, arguably more sophisticated in its terrain management.
- Features: The GX 470 was well-equipped with leather, navigation, and robust 4WD systems. European rivals often led in cutting-edge cabin technology and advanced driver aids, but this came with increased complexity. The LR3 offered advanced air suspension and terrain response systems, which were impressive for the time.
- Reliability: This is where the GX 470 truly shines. It is vastly more reliable and less prone to expensive, frequent breakdowns than the LR3, ML-Class, or X5 of the same vintage. While those European SUVs offered appealing features, their long-term maintenance costs and mechanical issues often became prohibitive.
- Price (Used): Due to its legendary reliability, the GX 470 often commands higher used prices and retains its value much better than its European counterparts. You might find a used LR3 or ML for less initially, but prepare for significantly higher ownership costs.
Against Asian Rivals (e.g., Acura MDX, Toyota 4Runner):
- Acura MDX (2006): More car-like unibody construction, better on-road dynamics and fuel economy, similar reliability, but significantly less off-road capability and towing.
- Toyota 4Runner (4th Gen, V8): Essentially the GX 470's less luxurious, more rugged sibling. Shares the same reliable V8 and chassis components, offering similar off-road capability and reliability at a lower price point and with fewer luxury amenities.
Recommendations:
- Similar Alternative: A 4th Generation Toyota 4Runner with the V8 engine is an excellent "same but different" alternative, offering nearly identical mechanicals and reliability without the Lexus luxury premium.
- Better Alternative (if off-road is less critical): A used Acura MDX for a more refined on-road experience and better fuel economy, but sacrificing heavy-duty capability.
- Better Alternative (if budget allows for newer models): A later Lexus GX 460 offers updated tech and a more refined V8, building on the GX 470's strengths.
Final Verdict: Is the 2006 Lexus GX 470 a Good Sport Utility Vehicle?
The 2006 Lexus GX 470 is an excellent choice for buyers who prioritize rugged reliability, comfortable luxury, and genuine off-road capability in a mid-size SUV. It is ideal for families needing a spacious, safe vehicle, adventurers who want to explore beyond paved roads, and those who appreciate the robust engineering of a body-on-frame platform.
It is absolutely worth buying as a used vehicle, offering incredible long-term value that far surpasses its initial depreciation. Given there was only one main GX 470 trim, focus less on specific trim levels and more on the individual vehicle's condition and maintenance history. Key conditions for purchase include a thorough pre-purchase inspection by a trusted mechanic, specifically checking for frame rust (especially in northern climates), proper functioning of the air suspension (or evidence of a well-done coil spring conversion), and comprehensive service records. While it demands higher fuel costs and potential for specific, costly age-related repairs, its legendary Toyota/Lexus dependability makes it a fantastic, versatile, and highly capable used luxury SUV that will reliably serve its owner for many more years and miles.
