Not sure what they did "wrong" at the 30k service, but, we took it back on Friday and they "reset the computer" and it is running much better.
I can't tell if it is back to 100% because of all the time that passed since the service and the fact that the loaner was an RX330 (felt more powerful) and I just bought a car with 300 HP. So, the RX feels SLOW to me.
It is much better. Thanks god for computers. :-)
