2006 HIGHLANDER HYBRID 4WD. SURGE WHEN BRAKING AND GOING OVER BUMPS. SINCE 2007, ON MANY REPEATED OCCASIONS, WHEN I GO OVER BUMPY ROADS AND BRAKING, I HAVE BEEN EXPERIENCING A SLIGHT ACCELERATION SURGE WHEN BRAKING. EVERY TIME I BRING MY HIGHLANDER INTO THE TOYOTA DEALER I ASK IF THEY KNOW ABOUT THE PROBLEM, WHAT CAUSES IT, AND IF THERE IS ANY SERVICE INFORMATION OR BULLETIN ON IT. FORM NOTES>>I CHECKED SERVICE BRAKES..THIS APPLIES TO THE REGULAR BRAKING SYSTEM-THIS TERM IS NOT CLEAR. AS TO WHAT MILEAGE--THIS IS A CONTINUING ONGOING PROBLEM SO THERE IS NO WAY TO INDICATE THAT ANSWER IN YOUR BOXES. SIMILARLY THIS HAS HAPPENED AT A WIDE RANGE OF SPEEDS, 15-35 MPH SO YOUR FORM DOES NOT PROVIDE A WAY TO INDICATE THAT. *TR

WHILE DRIVING ON I40 JUST AFTER LEAVING I17 AT FLAGSTAFF, AZ, DURING HEAVY RAINSTORM, VEHICLE DECELERATED ABRUPTLY TO ABOUT 45 MPH (WHILE ON CRUISE CONTROL SET AT 65), MANAGED TO PULL OFF AT NEXT OFF RAMP AND CAR DIED COMPLETELY ABOUT HALFWAY UP OFFRAMP (COUNTRY CLUB ROAD EXIT). WARNING MESSAGES INCLUDED "CHECK HYBRID SYSTEM", "CHECK 4WD SYSTEM", AND "CHECK AVS SYSTEM". AFTER CALLING FINDLAY TOYOTA IN FLAGSTAFF AND WHILE WAITING FOR TOW TRUCK, TURNED SYSTEM OFF FOR A FEW MINUTES AND ATTEMPTED RESTART WHICH WAS SUCCESSFUL AND DROVE TO TOYOTA DEALERSHIP. AFTER 2 DAYS OF DIAGNOSTIC CHECKS AND TECHNICIAN CALLS WITH TOYOTA, THEY TRIED TO TELL ME PROBLEM WAS DIRTY MASS AIR FLOW SENSOR. THIS VEHICLE HAD RECEIVED RECALL NOTICE AND HAD INVERTER AND AVS SYSTEM REPLACED AT A LITTLE OVER 100,000 MILES.
