2013 TOYOTA AVALON HYBRID Electronic Stability Control Esc Problems

AVALON RECALL NO 15V728. HAD THE RECALL "REMEDY" PERFORMED ON MY CAR 09/07/16 (WAS HAVING NO ISSUE WITH MY CAR BEFORE THE RECALL) AND NOW THE PCS WARNING BUZZES AND LIGHTS UP, AND THE RED BRAKE! MESSAGE LIGHTS UP EVERY TIME I DRIVE THE VEHICLE! CONTACTED TOYOTA CORPORATE OFC (CASE #1609142106 & #1611100472) TO REPORT THE ISSUE HAS NOT BEEN RESOLVED, AND EXPRESS MY FEAR THAT THE SYSTEM WILL NOW NOT WORK WHEN IT IS SUPPOSED TO, BUT THE "CASE MGR" (CORY CARTER) STATED "THERE IS NOTHING ELSE THEY CAN DO FOR ME", AND ADVISED ME TO "SEEK OUTSIDE ASSISTANCE FOR ANY ADDITIONAL HELP'. I ASKED IF THIS MEANT SEEKING AN ATTORNEY, TO WHICH HE REPLIED "YES". I FEEL MY CAR IS NOW UNSAFE, AND TOYOTA COULD CARE LESS!!
