A guide to problems, costs, maintenance and repair for your 2002 Lexus GS300

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.

Harsh shifting of the automatic transmission between 2nd and 3rd gears may be noted. Our technicians tell us this can often be corrected by updating the software in the powertrain control module (PCM).

This is a LUXURY car. Lexus thought about the driver from the feel of the car to the accessories that are provided. However, I've had 2 oxygen sensors that have had to be replaced. Other than that, a very nice car.
