MY 2005 TOYOTA 4 RUNNER HAD 6 UNINTENDED ACCELERATION INCIDENTS SINCE PURCHASED NEW IN NOVEMBER 2005. I HAVE MAINTAINED A LOG. THE INTENSITY OF UNINTENDED ACCELERATION VARIED, THE TACHOMETER REACHING 4000 AND ABOVE. DURATION WAS ESTIMATED FROM 3 SECONDS TO OVER 5 SECONDS. AMBIENT TEMPERATURE VARIED FROM ABOUT 73OF TO 34OF. ALL INCIDENTS OCCURRED BETWEEN EARLY JULY TO EARLY DECEMBER, AND NONE DURING VERY HIGH OR VERY LOW AMBIENT TEMPERATURES. IN ONE CASE THERE WERE SEVERAL CONSECUTIVE ACCELERATION SURGES. ALL INSTANCES WERE WITHIN 5 Ѕ MILES OF MY HOME. OCCURRENCE HAS BEEN SPORADIC, INFREQUENT, AND UNEXPECTED, AND AT LOW SPEED, MOSTLY IN CLOSE QUARTER PARKING SITUATIONS AND AT ALL TIMES WITH MY RIGHT FOOT ON THE BRAKE PEDAL. ON SEPTEMBER 11, 2008, I NOTIFIED TOYOTA COMPANY BY TELEPHONE OF THE INCIDENT HISTORY; I WAS GIVEN A CASE NUMBER. I COMPLIED WITH A DIRECTIVE TO REMOVE AFTER MARKET FLOOR MATS THAT COVERED THE FACTORY MATS. FYI, THE AFTER MARKET NON-FACTORY FLOOR MATS WERE NOT INTERFERING WITH OR NEAR THE ACCELERATOR, AND I HAVE HAD FURTHER UNINTENDED ACCELERATION SUBSEQUENT TO MAT REMOVAL. LIKEWISE, MY FOOT WAS NOT SIMULTANEOUSLY ON THE BRAKE AND ACCELERATOR PEDALS. IN DECEMBER 2009 THE TOYOTA DEALER SERVICE MANAGER DROVE MY VEHICLE 144 MILES OVER A WEEKїS PERIOD WITHOUT INCIDENT. I BELIEVE THAT EVIDENCE DOES NOT POINT TOWARDS A STICKING ACCELERATOR PEDAL BECAUSE IN ALL INSTANCES MY FOOT WAS ON THE BRAKE, AND IN AT LEAST ONE INSTANCE THE ENGINE ACCELERATION SURGED MULTIPLE TIMES. THE DEALER SAID THAT THERE COMPUTER DID NOT SHOW RELEVANT CODES. MY ASSESSMENT IS THAT THERE IS PROBABLY A MECHANICAL, ELECTRONIC, OR SOFTWARE DEFECT IN THE SPEED CONTROL SYSTEM. THIS NEEDS TO BE TAKEN MORE SERIOUSLY. THERE IS NO PLAN. I HAVE SUGGESTIONS: 1) TOYOTA DEALER/COMPANY DRIVE MY VEHICLE UNTIL AN INCIDENT OCCURS; 2) TOYOTA ENGINEERS TROUBLE SHOOT THE PROBLEM; THIS IS BEYOND DEALER EXPERTISE; 3) TOYOTA TEMPORARILY INSTALL MONITORING EQUIPMENT THAT CAN DOCUMENT FUTURE INCIDENTS. *TW
