The Lexus GX (GX470) of the early to late 2000s was a unique offering in New Zealand, blending Lexus luxury with rugged off-road capability derived from its Toyota Land Cruiser Prado underpinnings. This combination made it popular with those seeking both refinement and adventure. However, its age necessitates careful consideration of potential issues.
Common problems include rust (especially on the chassis and underbody), leaks in the hydraulic suspension system (AHC), worn suspension components, oil leaks (especially around the valve cover gaskets), and issues with the exhaust system. The 4.7L V8 engine is generally reliable, but requires regular maintenance to prevent issues such as timing belt failure. The fuel filler tube has been known to rust, so a careful eye needs to be kept on those for a WOF.
WOF tips
WOF failures are common for rust, worn suspension components (ball joints, bushings), brake issues (pads, rotors, calipers), and tire condition. Ensure all lights are functioning correctly. If the vehicle is equipped with AHC, ensure that it is functioning correctly and not leaking. Check for oil leaks and exhaust leaks. If the vehicle has been used for off-roading, check for damage to the underbody and suspension.
