My Lexus looks and drives new inside and out, garage kept etc.... I don't understand that at 70K miles that the catalytic converters would go bad like this. I have had the car 8 years and only put 10K miles on it. This is the 6th Lexus that I have owned and it just may be my last one flat out. I called the corporation after not getting any help from the dealer. The corporation didn't want to help either because of there not being enough complaints about it. I was told once there was enough complaints the will start an investigation on the issue. Not a good thing at all when someone is driving a car with your name all over it and things like this happens. This is not the only issue with this beautiful with just 70K on it, another complaint on the way!!!
