I have the extended 100,000 mile bumper to bumper on this car. Presently, 38,000 miles. At regular service last week, I was informed that the next service should include a Power Flush on both the Automatic Transmission and the Brake line. Reason, "condensation has added moisture to especially the brake line". The brake line is a sealed system and it seems to me that if there is moisture in it, then there is something wrong with the system and should be covered by the warranty. Honestly, I do not believe there is any moisture in the system. Am finding Toyota to be suspect.
