1999 Lexus GS400 Problems

Suspension & Steering -- Verified

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.

Engine -- Verified

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.

1999 Lexus GS400 Reviews

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?" Within a few minutes I was pulling up research on which Lexus fit the bill. After reading articles and reviews I fell in love with the GS400 (not the 300 nor the 430). If you read the differences you will know why the 400 is the way to go. Now the trick was to find one...1998 - 2000. I don't like the body style of the newer ones at all. I went on the hunt for a low miles (less than 75K) and in very nice condition. Wow...had no idea it would be a needle in a haystack. But...I found it. 63K, 1 owner, had an accident in the past but was Lexus repaired (and had my body shop check it over and they said it was fixed perfectly). I bought it. Since it is 12 years old and the rule when you talk to Lexus is 90K miles or 108 months I decided to have the timing chain, water pump, and 60K service done. The mechanic told me that the only other thing the car needed was a new set of bushing up front but it was as good as any new (2008 or newer) car he works on. He commended me for the purchase and told me if I ever found another one to buy one for him. The car is a rocket ship! It is all stock and easily hits 60 in less than 5.5 seconds. I put Mich PS2 tires on it right away and they grip great. I could not be happier. I just wish someone made a Nav replacement kit for these years...then it would be PERFECT.

I have had my GS400 for 10 years, and I have yet to have any major repairs done. I have 143,000 miles, and it still runs like a champ.
