2013 TOYOTA HIGHLANDER Electronic Stability Control Esc Problems

BOUGHT VEHICLE 'CERTIFIED' ON 04/20/17 AND FIRST OIL CHANGE 06/30/17 CORROSION ON BATTERY TERMINAL NOTATED. NEW BATTERY PURCHASED. 05/25/17, CORROSION IS AGAIN NOTATED. VEHICLE HAS BEEN THROUGH 2 SEPARATE OIL CHANGES AND NO CORROSION NOTATED. NOW DEALER IS STATING VERBALLY $5800 TO FIX TERMINALS AND CABLE DUE TO BATTERY ACID AND CORROSION LEADING TO ELECTRICAL DAMAGE. HARNESS DAMAGE. FLAW OF THIS VEHICLE IS ALL COMPONENTS ARE INTERCONNECTED. REP WILL NOT PUT IN WRITING, BUT IS SAYING MAJOR HAZARD. TOYOTA WILL GIVE ONLY $2500 TOWARDS COST. NOT DRIVING CAR AT THIS TIME.

THE COMPLAINT HAS TO DO WITH COMPUTER SYSTEMS ON THIS VEHICLE. SOME OF THE COMPLAINT IS CONVENIENCE, BUT WORRISOME BECAUSE OTHER SYSTEMS SEEM TO BE INVOLVED AS WELL. THE COMPUTER SCREEN HAS ALWAYS BEEN SLOW/HESITENT, WITH VARIOUS "GLITCHES". VEHICLE HAS GPS MAPPING SCREEN WHICH OCCASSIONALLY "DISCONNECTS" AND RESETS TO BLANK SCREEN. THE BLUETOOTH AND OTHER SYSTEMS HAVE ALSO "DISCONNECTED" AND COULDN'T BE RESET UNTIL THE VEHICLE WAS STOPPED AND TURNED OFF. THE HEADLIGHTS SOMETIMES DO NOT SHUT OFF, DAY/NIGHT DOESN'T WORK PROPERLY. HAVE HAD OCCASSIONAL PROBLEMS WITH DOOR LOCKS NOT WORKING AS THEY SHOULD. NEVER KNOW WHEN AND WHICH SYSTEMS WILL BE AFFECTED. I HAVE ALSO FILED A COMPLAINT ABOUT INTERMITENT NON-ACCELERATION ISSUES, WHICH MAYBE RELATED.
