2004 Lexus GX470

TL*THE CONTACT OWNS A 2004 LEXUS GX470. HE EXPERIENCED A RECURRING FAILURE IN WHICH THE BRAKES WOULD ENGAGE WHILE DRIVING AT ANY SPEED AND THE VEHICLE WOULD PULL TOWARDS THE RIGHT. DURING THE FAILURE THE VSC LIGHT ALSO ILLUMINATED ON THE DASHBOARD. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER ON FOUR OCCASIONS WHO STATED THAT THE VEHICLE WAS OPERATING AS NORMAL. THE VEHICLE WAS NOT REPAIRED AND THE FAILURE CONTINUED TO OCCUR INTERMITTENTLY. THE FAILURE MILEAGE WAS 70,000. THE CURRENT MILEAGE WAS 90,000.

PROBLEM WITH VSC ON MY 2004 LEXUS GX470. I WAS DRIVING FROM A SKI RESORT ON SNOW COVERED ROAD AT APPROX 35-37 MPH. THE FRONT RIGHT WHEEL HIT A POTHOLE AND THE REAR OF THE VEHICLE SHOT SIDEWAYS AND WE WERE HEADED OFF THE ROAD TO THE RIGHT, THEN TRACTION CONTROL OR SOMETHING KICKED IN AND WE SHOT INTO ONCOMING TRAFFIC. I TRIED TO STEER BACK INTO OUR LANE AND THE REAR LEFT AGAIN SENT US INTO A SIDEWAYS SKID ACROSS THE RIGHT LANE AND HEADED OFF OF THE ROAD UNTIL THE RIGHT REAR HIT A POLE. THE CAR CONTINUED TO MOVE AND SHOT US BACK INTO THE RIGHT TRAFFIC LANE AND I WAS ABLE TO FINALLY GAIN CONTROL AND PULL OVER. I HAD NO CONTROL OF THE VEHICLE AND WE VEERED BACK AND FORTH ACROSS THE HIGHWAY FOR SEVERAL YARDS. I HAVE DRIVEN IN WINTER CONDITIONS FOR YEARS AND HAVE BEEN IN SLIDES BEFORE, BUT NEVER WHERE THE CAR CHANGED DIRECTION AND VEERED BACK AND FORTH INSTEAD OF MAINTAINING THE SLIDE TRAJECTORY. I AM CONVINCED THAT THE SENSORS ARE WRONG OR SOMETHING IS WRONG WITH THE VSC AND REPORTED MY CONCERN TO MY INSURANCE COMPANY AND ALSO TO THE LEXUS DEALERSHIP. I TOOK THE VEHICLE TO LEXUS AND HAD THEM RUN FULL DIAGNOSTIC, INCLUDING ZERO POINT/YAW RATE. THEY REPORTED THAT THERE WERE NO ISSUES WITH THE VSC. THE TIRES AND BRAKES CHECKED OUT TOO. I HAVE ONLY HAD THIS VEHICLE SERVICED BY LEXUS, EVEN OIL CHANGES. I HAVE BEEN SEARCHING THIS SITE AND OTHERS FOR SIMILAR ESC/VSC COMPLAINTS AND HAVE FOUND A FEW, THEN WHEN THE ANNOUNCEMENT ABOUT THE VSC PROBLEMS WITH THE NEW LEXUS GX CAME OUT, I KNEW I SHOULD REPORT THIS. THERE SHOULD BE AN INVESTIGATION OF ALL LEXUS GX VSC SYSTEMS - WHETHER THEY DEVELOP FLAWS OVER TIME OR IF THERE IS SOME ISSUE INHERENT WITH THE SYSTEM THAT CAUSES THE UNCONTROLLED SKIDS. THIS IS THE SECOND TIME THE CAR HAS GONE INTO AN UNCONTROLLED SLIDE - THE FIRST TIME THERE WERE NO DAMAGES. *TR
