NHTSA Complaint #10819160 — 2009 TOYOTA SIENNA

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.
