Lexus GS400 Problems

Creaking Type Noise From Front Suspension

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.

Sludge Buildup on Engine Due to Infrequent Oil Changes

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.

Lexus GS400 Reviews

240,000 still running strong. Replaced auto transmission due to bad input shaft seal leak, but wouldn't drive anything else! The luxuries of this car for a '98 are so amazing! Recommend this car to everyone!
What can you say about a car that is 16yrs old and has never had a spark plug change? My '99 GS 400 has 215,000 miles and has hardly ever had a problem. I'm convinced it will run forever. I've replaced more parts that wear out like the tires and brakes than anything having to do with the motor and transmission. They are solid. Never an electronic or computer issue. I've thought about trading it...
My '99 GS400 is now 15 years old with 210,000 miles with nary a problem. Reliable, fast, and smooth. Other than normal maintenance it has never had an issue. A friend has an '01 LX470 (same motor) with 300,000 miles and I plan on getting at least that much out of mine. I have no plans on ever selling it. Fantastic car!
