2009 TOYOTA SIENNA Electronic Stability Control Esc Problems

ON DRY PAVEMENT DRIVING ABOUT 35-40 MILES AN HOUR THE VSC TRACTION SENSOR CAME ON LIGHTS AND SOUND AND HIT MY BRAKES MY STEERING WENT TO THE RIGHT I ALMOST GOT IN AN ACCIDENT THIS IS THE THIRD TIME THIS HAS HAPPENED AND THEY CAN'T FIGURE OUT WHAT'S WRONG WITH IT. *TR

I WAS DRIVING MY SIENNA ON A 2 LANE TOWN ROAD AND WITHOUT WARNING SMELLED SMOKE. AS I WAS PULLING OVER CARS IN THE ONCOMING LANE WERE HONKING AT ME AS THEY SAW THE FIRE UNDERNEATH WHERE THE ENGINE IS. WHEN I PULLED OVER SMOKE ENTERED INTO THE CAR. I STEPPED OUT, HEARD A POP, AND NOW THE ENTIRE FRONT OF THE CAR WAS FULL ON FIRE. THE FIRE DEPARTMENT ARRIVED ON SCENE QUICKLY AND EXTINGUISHED THE FIRE. I FILED AN INCIDENT REPORT WITH TOYOTA. I RECEIVED A CALL FROM A MAN SAYING HE WAS HIRED BY TOYOTA TO INVESTIGATE THE FIRE AND REPORT BACK TO THEM. TO DATE, I HAVE RECEIVED ZERO COMMUNICATION FROM ANYONE AT TOYOTA REGARDING THIS SERIOUS MATTER.

AFTER DRIVING THE VEHICLE APPROXIMATELY 10 MILES, A JERKING CAN BE FELT, AND SHORTLY THE CHECK ENGINE, VSC, AND TRAK LIGHTS COME ON. CONTINUED DRIVING SOMETIMES RESULTS IN JERKING AND/OR LOSS OF ACCELERATION, INCLUDING LOSS OF VEHICLE MOVEMENT CONTROL. THE LOSS OF ACCELERATION TYPICALLY OCCURS DURING A TURN OR IN STOP-AND-GO TRAFFIC. THE SITUATION HAS OCCURRED TO A LESSER DEGREE IN HIGHWAY TRAFFIC WHEN PASSING OTHER VEHICLES. ANY OF THESE SITUATIONS IS OF CONCERN, BUT ESPECIALLY THE LOSS OF ACCELERATION BECAUSE OF THE POTENTIAL FOR OTHER VEHICLES TO CRASH IN TO US. THIS HAS OCCURRED ON VARIOUS DATES OVER THE LAST APPROXIMATELY SIX (6) MONTHS. HAVE HAD COMMUNICATION WITH OUR LOCAL TOYOTA DEALER SERVICE DEPARTMENT, TOYOTA CORPORATE CUSTOMER SERVICE, AND A NON-TOYOTA AUTO REPAIR SHOP; ALL TO NO AVAIL. NONE OF THEM HAVE BEEN ABLE TO TELL ME WHAT THE REAL PROBLEM AND HOW TO FIX IT FOR SURE.
