I PURCHASED A 2007 PRIUS ON 8/31/07. BOTH MY WIFE AND I OCCASIONALLY EXPERIENCE A SLIGHT FORWARD SURGE OF THE VEHICLE WHEN THE BRAKES ARE APPLIED. I HAD THE CAR INSPECTED ON 5/14/08 FOR THIS CONCERN AND HAVE A TOYOTA WORKORDER STATING THE ISSUE AND INDICATING THAT THEY COULD NOT FIND A PROBLEM. I REPEATED MY CONCERNS ON ADDITIONAL SERVICE VISITS (NOT WRITTEN UP ON THE WORKORDER AND, AGAIN, NOTHING WAS FOUND. ON 8/3/09 I WAS INVOLVED IN A MINOR ACCIDENT WHEN I FAILED TO COMPLETELY STOP BEHIND A CAR SITTING AT A TRAFFIC LIGHT AND STRUCK THAT CAR IN THE REAREND. MY CAR REQUIRED A BUMPER REPLACEMENT AS THE PLASTIC BUMPER CRACKED ON IMPACT WHILE THE OTHER VEHICLE ONLY EXPERIENCED SCRATCHED PAINT ON IT'S REAR BUMPER. I AM CONCERNED THAT THERE IS SOMETHING SYSTEMIC WRONG WITH THE BRAKES ON MY CAR AND WANTED TO REPORT THIS AND, HOPEFULLY, HEAR BACK AS TO THE NUMBER OF SIMILAR REPORTS THAT YOU HAVE RECEIVED. *TR
