2000 Lexus GS300 Problems
RepairPal has identified the most common problems with the 2000 Lexus GS300 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Sludge can build up in the engine because Lexus did not recommend frequent enough oil changes. Lexus will sometimes offer a discount on cleaning the engine if necessary. Owners who changed their oil every 3,000 miles did not experience these problems. This sludge build up can lead to excessive oil consumption.
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.
