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 transmission control module (TCM).
All wheel drive models may develop a creaking type noise from the front suspension when driving over uneven road surfaces. Our technicians tell us revised front sway bar bushings are available which may correct this concern.
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.
