1999 Lexus GS400 Problems

Excess Engine Oil Consumption

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.

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.

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...
bought the car with 112,000 miles one it and now have 255,000 miles on her.... drives perfect still. engine is as strong as ever, only problems have been alternator and a slow drain on the battery that will kill the car after not being driven for a couple days. in all great car.
I bought a 1996 LS400 with 100K miles about 4 years ago. The car is a tank. So...when we were ready for another car I decided I wanted something sporty and practical. We looked at BMW X5, BMW 540i, Range Rover (not reliable...and rediculously expensive to maintain), and one day I walked by the old airport car LS400 and thought..."why am I not considering another Lexus?"
