2005 Lexus Gx problems

Common 2005 Lexus Gx problems

The Lexus GX 470, a popular SUV, has been known to have several common problems based on complaints from owners. These issues are primarily related to the air suspension system, which is a crucial component of the vehicle's performance and safety.

• Sensor Failure: The Lexus GX 470 has sensors in each wheel that gather information and send it to the electronic control unit (ECU). These sensors can fail, affecting the vehicle's automatic height monitoring system. This can cause the vehicle to have trouble maintaining its ride height, sag in the rear, or lean to one side.

• Control Panel Faults: The control panel or control module is the air suspension system's "brain." When it fails, the air suspension cannot perform optimally, leading to a less comfortable driving experience.

• Air Compressor Failure: The air compressor generates pressurized air and pumps it through the springs, elevating the vehicle. These compressors tend to wear out over time, reducing the amount and intensity of air produced. This can lead to a less comfortable ride, especially when the vehicle is loaded to maximum capacity.

• Air Spring Failure: Air springs are rubber bellows that inflate and deflate depending on the amount and intensity of air. Their constant up-and-down motion causes them to weaken over time at the top and bottom. This can lead to a loss of strength in the air suspension system, making it difficult for the vehicle to lift properly when loaded.

• Airbag Damage: The airbag stores the air generated by the air compressors and sends it to the control module. When dry rot and punctures cause it to leak or burst, the air volume drops, so there's not enough air to lift the SUV. This can lead to a less comfortable ride and potential safety issues.

• Valve Block Failure: The valve block distributes pressurized air to the air springs, elevating the vehicle. A failed valve block essentially cuts that air supply, leading to a less comfortable ride and potential safety issues.

These problems can be identified by various symptoms, such as a warning light on the dashboard, sagging or leaning of the vehicle, a nose dive when braking, longer braking distances, unusual noises from the strut or air compressor, an overrunning compressor, bumpier rides, and a bounce test result that shows weak struts or shocks.

To reset the Lexus GX 470's air suspension system, one can follow specific steps, including turning off the vehicle, waiting for 30 seconds, turning the key to the "on" position without starting the engine, pressing the "auto level" button for 10 seconds, and then turning off the vehicle again for 30 seconds before starting it up.

In addition to these air suspension problems, the Lexus GX 470 has been known to have issues with its timing belt and water pump, which should be replaced every 90,000 miles. The CV bolt can also leak, potentially leading to the need for a replacement of the CV axle joint. The blizzard white paint has also been a recall issue, with the plastic dash potentially cracking and looking ugly
