Sorry, but this doesn't make sense! <_<
I agree with CODE58. I have been working with Lexus for 14 years and Toyota for 6 years before that. I don't see how an oil pump affects oil consumption. But, then again, the service consultant doesn't usually know a whole lot about cars anyway. I'm sure the primary concern was the valve seals, not completely unusual, which seems to have been taken care of at the same time. I'm sorry to hear you had a scare with your Lexus, but I'm glad to hear your local dealership stood behind their product(something you wouldn't get anywhere else). The RX300 is one of the best cars we have ever produced and we try to promote an entire ownership experience. Good luck and enjoy your car!
