2003 Lexus LS430 Problems

Rear Window Sunshade Fails and Makes Grinding Noise

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. 

Erratic Operation of the Multi-Display Panel

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 Shift Quality at Low Speeds

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

Purchasing this car is one of the best decisions I have made. I purchased it new and absolutely love it. I have roughly 215,000 miles and it still has a great ride.

Major services (at my independent shop) at 15k, 30k, 45k and 60k intervals. I honestly believe that this vehicle will outlive me-eh!
I have had this car for three years and it hasn't had one problem. I bought it as a lease end, and it is a joy to ride every single day. The handling is wonderful, and the feel of luxury is better than my old Mercedes Benz. In addition, it gives the quietest, smoothest ride of any car I know. I plan on holding onto this car until it dies or I die...
