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.
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.

I changed the actuator and closed the door. Now I can't get it open.
Is the serpentine belt the same thing as the drive belt?
2003 Lexus LS430 Reviews
Acquired this as a lease end - Lexus certified vehicle in 2007 with 45k miles. Major repairs consist of new brake pads, tires and battery plus regular oil changes at 5k intervals using regular Pennzoil and K&N oil filters. Use mid-grade gas with no problems. 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...
