Known Problems

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

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. 

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.

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.
