Known Problems

The motor for the rear window sunshade in the 2001-2006 Lexus LS430 is known to fail. When this occurs, the sunshade will not extend down the window, and a grinding noise is heard until the motor fails as well. 

Replacement of the sunshade assembly is necessary to correct this failure, however, removing the fuse for the sunshade will stop the motor from making the irritating grinding noise. 

Various issues may develop with the multi-display panel. Our technicians tell us a redesigned multi-display panel is available which may correct these concerns.

Poor quality low speed transmission shifting may be noted. Our technicians tell us updated transmission software is available which may correct this concern.

Vehicles equipped with premium Mark Levinson stereo may experience no sound or volume that goes to maximum level by itself. An improved amplifier is available to rectify this problem.

When filling the fuel tank, the fuel nozzle may click off before the tank is full. Our technicians tell us a revised fuel filler neck is available which may correct this concern.

The Check Engine Light may illuminate with an engine misfire code stored (P0300 - P0306). Our technicians tell us upgraded software is available for the powertrain control module (PCM) which may correct this concern.

The Check Engine Light may illuminate with stored codes P0133 and/or P0153. These may be "false" codes which can be corrected by reprogramming the powertrain control module (PCM) with upgraded software.

A knocking noise may develop from the AC compressor. Our technicians tell us a redesigned compressor is available to correct this issue.

The Check Engine Light may illuminate due to an O2 sensor heater fault. Most commonly the affected O2 sensor will need to be replaced to correct this concern.

A squeak type noise may be noted from one or both front seats. Squeaks can be caused by contact between the seat track locating pins and the vehicle floor pan. Our technicians tell us the repair involves removing some of the seat locating pins.

The traction/stability control light may illuminate due to a faulty steering angle sensor. Our technicians tell us an improved sensor is available to correct this concern.

Vehicles equipped with the Lexus Dual Mode Mobile phone system may experience poor quality sound, particularly from land-line calls. A redesigned telephone computer and microphone are available to correct this problem.

An abnormal noise may be noted from the steering column. Our technicians tell us this may be due to insufficient strength of the telescoping steering column cable, a redesigned cable has been made available to correct this concern.
