2008 Toyota Rav4 Electronic Stability Control Esc Problems

THIS WAS MY PROBLEM ONE YEAR AGO AND LISTED ON THIS PAGE UNDER THE DATE 3/6/2015 ABS LIGHT, VSC LIGHT, BRAKE LIGHT AND TRACTION CONTROL LIGHT ILLUMINATED CAUSING ALL SYSTEMS TO BE INOPERATIVE. AFTER TAKING CAR TO LOCAL DEALER PROBLEM WAS FOUND TO BE BAD LEFT WHEEL SPEED SENSOR, HARNESS FOR SENSOR AND WHEEL HUB THAT HAD CORROSION ON IT POSSIBLY FROM LIVING IN AN AREA THAT DEICES ROADS WITH SALT. IN MY RESEARCH IT HAS BEEN BROUGHT TO MY ATTENTION THROUGH SEVERAL TOYOTA BLOGS THIS IS A RECURRING PROBLEM AROUND THE COUNTRY. SEVERAL PEOPLE HAVE HAD THE SAME COMPLAINT AND THE ASSOCIATED COST TO FIX THIS PROBLEM IS EXPENSIVE. IF AN OWNER FAILS TO FIX THE PROBLEM THE OUTCOME COULD BECOME CATASTROPHIC IN INCLIMATE WEATHER. EXACTLY ONE YEAR LATER THE RIGHT SIDE WHEEL HUB ASSY. AND WIRING HARNESS WENT OUT. THIS TIME I CHANGED IT ALL MYSELF SAVING ALMOST $600 FROM HAVING IT DONE AT TOYOTA DEALER. THIS PROBLEM IS GOING TO KILL SOMEONE. WHILE WAITING FOR THE PARTS TO COME IN THE CAR WAS BEING DRIVEN BY MY WIFE DURING A RAINSTORM. ANOTHER DRIVER PULLED OUT IN FRONT OF HER AND SHE HAD TO BRAKE HARD. DUE TO THE ABS BEING INOP. IT CAUSED THE VEHICLE TO SLIDE. I HAVEN'T FOUND ANY OTHER COMPLAINTS ON HERE BUT I'M ALMOST POSITIVE IT HAS HAPPENED TO SOMEONE ELSE. IT'S A TERRIBLE DESIGN AND LIKE I SAID SOMEONE WILL BE KILLED DUE TO THE LACK OF CONCERN.
