1998 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.

1998 Lexus GS400 Reviews

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!
I am a sales associate at a pre-owned car dealership that sells all makes & models. I am extremely happy with my 1998 gs400, it has 150k mls. now & engine purrs like a kitten, or I can also make it sound like a tiger depending how I'm driving. Very good gas milage for a V8, I am convinced it's simply one of the very best cars ever made & it still looks better than most new sport sedans made today.
My GS400 now has 128K miles & it still looks fantastic & runs like a scared rabbit! Still getting 20-25MPG from 300HP motor is the best. I just upgraded the tail lights w LED lights & it looks like a 2012 model. I also upgraded to slotted rotors & now run ceramic brake pads & this car stops w the best. Make sure you change the timing belt/water pump each 100K & the GS 400 can easily go 300-4...
