2004 Lexus Gx problems

The Lexus GX (Japanese: レクサス・GX, Hepburn: Rekusasu GX) is a mid/full-size luxury SUV sold in North American and Eurasian markets by Lexus, a luxury division of Toyota. The GX is based on the Toyota Land Cruiser Prado, from which it derives its off-road capability. Lexus introduced the first generation, known as the GX 470 in 2002, and subsequently became the third SUV to enter the Lexus lineup. A full-time four-wheel drive system is standard with low-range gearing. The 4.7-liter V8 engine in the GX 470 was the same as used on the larger LX 470. The firm next introduced the second-generation model in 2009, badged GX 460 to reflect the switch to a 4.6-liter V8 engine. Lexus later released a lower displacement GX 400 in 2012 for the Chinese market, with a 4.0-liter V6 engine. The third-generation model introduced in 2023 uses the GX 550 moniker with a twin-turbocharged 3.4-liter V6 engine and GX 550h with a turbocharged hybrid electric 2.4-liter four-cylinder engine.

As of 2024, the GX is positioned between the larger LX or TX and the smaller RX. Though it is thought the GX has always been larger than the RX, from 2015 to 2022, the RX is slightly longer and slightly wider than the GX and therefore the GX was considered smaller. All GX production has occurred at the Tahara plant in Japan, alongside the Land Cruiser Prado and the export-minded Toyota 4Runner.

Some countries classify the GX as a full-size vehicle (e.g., Australia), while some classify it as a mid-size vehicle (e.g., US), depending on local regulations.

Common 2004 Lexus Gx problems

Based on complaints from owners, common problems with the Lexus GX 2004 include:

  1. Air Suspension Issues:
    • Sensor Failure: Sensors in each wheel can fail, affecting the automatic height monitoring system.
    • Control Panel Faults: The control panel is the system's "brain," and when it fails, the air suspension cannot function optimally.
    • Air Compressor Failure: Over time, the air compressor can wear out, reducing the amount and intensity of air produced.
    • Air Spring Failure: Rubber bellows that inflate and deflate can weaken over time, affecting the vehicle's ability to rise and drop properly.
    • Airbag Damage: Leaks or bursts in the airbag can lead to a drop in air volume, affecting the vehicle's lifting capacity.
    • Valve Block Failure: A failed valve block can disrupt the distribution of pressurized air to the air springs, impacting the vehicle's elevation.
  2. Other Common Issues:
    • Secondary Air Injection Failure: This problem is particularly reported in the 2006 Lexus GX 470 model.
    • Timing Belt and Water Pump: It's crucial to check if these components have been replaced, as failure to do so can lead to costly repairs.
    • CV Boot Leaks: Common issue that may require replacement of the CV axle joint.
    • Rotors Warping: Stock rotors can warp under heavy braking or while towing, necessitating an upgrade.
    • Plastic Dash Cracks: The plastic dash can crack and look unsightly, with Lexus offering replacements for free until 2018.
    • Touchscreen Navigation System: Some models with touchscreen navigation may fail, affecting climate control and other functions.

These issues can impact the performance, safety, and comfort of the Lexus GX 2004. Regular maintenance, timely repairs, and thorough inspections can help mitigate these problems and ensure a smoother driving experience.
