It is Lexus' largest and most expensive luxury SUV. Four generations have been produced, all based heavily on the long-running Toyota Land Cruiser SUVs. The first-generation LX 450 started production in 1995 as Lexus' first entry into the SUV market. Its successor, the LX 470, premiered in 1998 and was manufactured until 2007.

The fourth-generation model has a twin-turbocharged V6 engine powertrain and seats for seven passengers as standard and four passengers as an option. The second-generation LX 470 shared exterior styling with the Japanese domestic market Land Cruiser Cygnus.

According to Lexus, the "LX" name stands for "Luxury Crossover". However, some Lexus importers use the backronymic name, "Luxury Four Wheel Drive".

Common 2004 Lexus Lx problems

Based on complaints from owners of the 2004 Lexus LX 470, several common problems have been reported:

Transmission Issues: Owners have noted a noticeable backlash in the transmission after 200,000 to 300,000 kilometers. This backlash is described as a knock or bump that occurs when gas is added while coasting. The total backlash affects various components like splines, joints, hub flanges, CV joints, pinion gears, and shafts in the front and rear gearboxes. Resolving this issue often involves replacing spline connections or specific components like the front hubs and CV joints.
Suspension Problems: The Lexus LX 470 is equipped with an AHC hydraulic suspension system with ride height control, which can start to malfunction with age. Common issues include sensor failures, hydraulic accumulator fading, system tube leaks, and pump malfunctions. Additionally, the front suspension may experience problems with ball bearings, upper and lower ball joints, and silent blocks after 150,000 to 200,000 kilometers.
Brake System Concerns: Periodic maintenance is required for the brake calipers, which can deteriorate over time. Subsequently, issues may arise with the main brake cylinder or the electric pump. Restyled models with VGRS (Variable Gear Ratio Steering) may have had a service campaign to address safety concerns related to the steering system.
Corrosion and Rust: Owners have reported issues with paint bulges on the tailgate, corrosion in various areas like wheel arches, windshield frame, and the lower part of the engine shield. Additionally, the pipes of the rear air conditioner are prone to corrosion, leading to leaks.
Electrical and Interior Problems: Some complaints include failures in the electronic unit responsible for interior functions like lighting, sunroof control, and steering wheel operations. Issues with the VGRS control unit and the SRS unit near the driver's seat have also been noted.

These problems highlight the importance of regular maintenance and thorough inspections when considering or owning a 2004 Lexus LX 470 to address these common issues and ensure the longevity and performance of the vehicle.
