Electrical Failure problems of the 2005 Lexus RX330

Failure of built-in cd changer and radio system leads to failure of heating, air conditioning, and related electrical components. Cd changer system on car displayed "error 4" message and would no longer play or function. Shortly after, various electrical systems failed (heating, air conditioning, radio, interior lighting). Lexus contacted and informed owner of repair costs $1,000. Owner appealed to Lexus, who offered to provide "some flexibility" of up to a $400 credit for the repair. Owner found this unacceptable and had non-Lexus third party repair the built-in cd changer, navigation, radio unit for $392. Repair solved safety and operation problems.
