Common 1998 Lexus Lx470 problems

The Lexus LX470, a luxury SUV produced from 1998 to 2007, has been known to have various common problems based on complaints from owners. One of the most frequently reported issues is related to the suspension system, particularly the accumulators and height control sensors.

Accumulators, which are part of the suspension system, are known to be a common problem in the LX470, especially in the 1998 model. These components can cause the vehicle to ride like a pogo stick, leading to an uncomfortable driving experience. Replacing them can be quite expensive, with costs potentially reaching up to $2,000.

Another suspension-related issue is the height control sensors, which can become rusted on the inside, causing the vehicle to sit lower in the front than in the rear. This problem is often described as the vehicle losing connection at times on the inside, leading to a height difference between the front and rear of the car. It is recommended to have this issue inspected by Lexus professionals, as they can perform more thorough diagnosis with their specialized scan tools.

Apart from suspension problems, the Lexus LX470 can also experience issues with its VSC TRAC and VSC OFF systems, which can cause the engine to act like it is starving for fuel at idle. This problem can be especially noticeable when stepping on the gas pedal, as the engine smooths out until the gas is released. This issue can be caused by a variety of factors, including a sticking valve in the suspension hydraulics or a computer problem. In some cases, the problem may not be solvable, leading owners to sell their vehicles.

The LX470's fuel pump, ignition coils, and oxygen sensors can also fail from time to time, requiring replacement. Additionally, the camshaft and crankshaft position sensors can wear out, leading to potential engine performance issues. Regular oil updates are crucial for maintaining the longevity of the transmission and engine, with the first complaints about performance arising after 300,000 to 500,000 kilometers

The front suspension of the LX470, specifically the ball bearings, can wear out after 150,000 to 200,000 kilometers. This issue is more prevalent in analogs, which typically last for 30,000 to 100,000 kilometers. Original ball joints, on the other hand, can withstand more than 150,000 kilometers without issue. The AHC hydraulic suspension with ride height control, which is standard in all LX470 models, can also act up with age. This is often due to issues with sensors or the hydraulic accumulators, which can fade or lose tightness after 200,000 to 300,000 kilometers. The pump may also require attention after 300,000 to 400,000 kilometers

Shock absorbers in the LX470 can leak if not replaced periodically, and the power steering pump may howl over time due to wear. Regular maintenance, including replacing brake calipers and the main brake cylinder, is essential for maintaining the LX470's performance and longevity

In summary, the Lexus LX470, particularly the 1998 model, has several common problems related to its suspension system, including issues with accumulators and height control sensors. Other issues include potential problems with the VSC TRAC and VSC OFF systems, as well as general wear and tear on various components such as the fuel pump, ignition coils, oxygen sensors, and ball bearings. Regular maintenance and inspections are crucial for ensuring the LX470's longevity and performance.
