Remedy: TOYOTA WILL NOTIFY OWNERS WITH AN INTERIM LETTER INITIALLY INSTRUCTING THEM TO BRING THEIR VEHICLE TO AUTHORIZED DEALERS TO INSPECT FOR CORROSION. A SECOND NOTICE WILL BE SENT WHEN THE PERMANENT REMEDY IS AVAILABLE. FOR MORE INFORMATION, PLEASE SEE TOYOTA'S AMENDED RECALL REPORT OF JULY 19, 2010. THE SAFETY RECALL IS EXPECTED TO BEGIN ON OCTOBER 12, 2010. OWNERS MAY CONTACT TOYOTA AT 1-800-331-4331.
