Update - July 17, 2010 - Just got the car back from the auto body shop after a week. Changed it from Pearl white to Pearl Black. However, now the car has huge power loss with ticking noise when I drive. I think this Lexus is going to drain my bank.
Update: July 19, 2010 - I took my GS400 to the mechanic who tested the car and advised me to save money by using "Guaranteed to Pass" fuel additive to flush out the fuel system. This actually resolved the problem.
Update on my review (Sep 24, 2010) - I replaced all 4 brakes. All were worn out.
Replaced the front drivers side engine mount. Very expensive.
Now the car's electric light is on. Also the car is still making the ticking noise and there is a significant loss of power. I think this car is going to drain me dry. I will stay away from Lexus next time. I will perhaps buy a basic car like a Toyota Corolla.
Update on my review (April 26, 2011) - Just replaced front driver's side upper control arm. Also the car is swaying a lot even after an alignment was done. Dealer showed me the rack and pinion bushings were worn out. I'm going to see if I can get the bushings, rather than replacing the R&P.
Update June 5, 2011 - Brakes seized up. Rotors, brakes and calipers were replaced for an astronomical price. There is a huge vibration, which keeps returning even after 3 wheel balances. Similar things happened to my previous Lexus SC400. Lexus's are very expensive cars to maintain.
Update on my review (May 29, 2012) - Since owning this car, I have spent so much money on fixing this and that, that I have wasted a small fortune. Parts are so expensive, it's ridiculous. Who says Lexus's are reliable? Not me. This is a blood sucking car. I have since sold my car for dirt cheap price, and bought a brand new 2012 Hyundai Genesis Coupe 2.0T. I really regret buying that Lexus GS400. I am actually hugely in debt because of this "unreliable" piece of junk.
