Known Problems

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.

A creaking type noise may develop from the front suspension when driving over uneven road surfaces. Our technicians recommend inspection of the front sway bar bushings for deterioration and related hardware for correct tightness.
