2006 Lexus Gx problems

Common 2006 Lexus Gx problems

The Lexus GX 470, a popular choice in the SUV market, is known for its combination of performance and luxury. However, older, high-mileage models of this vehicle often face issues with the air suspension system, which can lead to various problems such as trouble maintaining ride height, sagging in the rear, leaning to one side, and suspension warning lights.

Here are six leading causes of Lexus GX 470 air suspension problems:

1. Sensor failure: The Lexus GX 470 has sensors in each wheel that gather information and send it to the electronic control unit (ECU). Damage to these sensors can affect the vehicle's automatic height monitoring system.
2. Control panel faults: The control panel or control module is the air suspension system's "brain." It's a computerized unit that gives you a comfortable driving experience. When the control panel fails, the air suspension cannot perform optimally.
3. 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.
4. Air spring failure: Air springs are rubber bellows that inflate and deflate depending on the amount and intensity of air, causing the vehicle to rise and drop. Their constant up-and-down motion causes them to weaken over time at the top and bottom, leading to a loss of strength and inability to lift properly, especially when loaded to maximum capacity.
5. 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.
6. 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.

To troubleshoot Lexus GX 470 air suspension problems, there are eight signs to look out for:

1. Warning light: A bright light on the dashboard indicates a damaged air suspension.
2. Sagging: A damaged air suspension system cannot support the vehicle's weight, leading to sagging at the back or leaning to one side.
3. Nose dive: A nose dive happens when you come to a complete stop and the front of your vehicle dips, indicating weakened shocks or struts in front.
4. Long braking distance: A damaged air suspension system puts more pressure on your brake calipers, increasing stopping distances.
5. Unusual noise: Any unusual noise, especially from the air compressor, could indicate a suspension system issue.
6. Overrunning compressor: The air compressor should stop running once it reaches a sufficient limit. If it keeps going, there is a chance the compressor is faulty.
7. Bumpier rides: The Lexus GX 470's air suspension system absorbs the roughness on the road and improves riding comfort. As the struts or shocks begin to wear out, you feel the direct impact of driving.
8. Bounce test: Push down the bumper at each corner of the vehicle. If it takes a long time to rise or bounces up and down before settling, there is a chance your suspension is giving out.

In summary, the Lexus GX 470 is a reliable SUV, but older models may face air suspension issues due to sensor failure, control panel faults, air compressor failure, air spring failure, airbag damage, and valve block failure. To troubleshoot these problems, look out for warning lights, sagging, nose dives, long braking distances, unusual noises, overrunning compressors, bumpier rides, and perform a bounce test.

What year to avoid GX 470?

The highest number of complaints involved the 2006 Lexus GX470. However, the 2003 model year is considered the worst GX470 for reasons like higher repair cost for its particular problems.

Is Lexus GX reliable car?
