Open the full vehicle complaint log (all categories)CONTINUATION OF MY REPORT. ABOUT A MONTH LATER THE SAME SUDDEN ACCELERATION OCCURRED BUT IN REVERSE AS THE DRIVER WAS LEAVING HER HOME AND THIS TIME SHE COULD NOT STOP THE VEHICLE, GOING THRU THE CONCRETE FENCE OF HER FRONT NEIGHBOR TAKING A SIDE OF THE NEIGHBOR HOUSE, DOWN A HILL AND HITTING TWO AIR CONDITIONER UNITS AND AN ELECTRICAL GENERATOR, DAMAGING THE WHOLE RIGHT SIDE OF THE VEHICLE AND THE REAR, BRAKING THE REAR DRIVE TRAIN AND GETTING STUCK IN A CONCRETE WALL WHICH SAVE THEIR LIFE. IF THE VEHICLE WOULD HAVE GONE 10 MORE FEET IT WOULD HAVE DROP IN AN APPROXIMATELY 800 TO 900 FEET CLIFF AND PROBABLY WOULD HAVE LOST THEIR LIVES. THE VEHICLE WAS A TOTAL LOSS. ACCORDING TO THE DRIVER SHE PUT ON HER BRAKES AND THEY DID NOT WORK. ACCORDING TO THE WITNESSES THERE WAS ONLY ONE TIRE BRAKE TRACK ON THE ROAD WHICH IT WAS GONE BY THE TIME I WENT TO INVESTIGATE. MY THEORY IS THAT ELECTRIC SURGES FROM THIS HIGH INTENSITY CABLES INTERFERE WITH THE THROTTLE CONTROL AND ACCELERATE THIS VEHICLES. IT IS THE ONLY LOGICAL EXPLANATION. IF THERE IS A WAY TO TEST THIS THEORY I SURE WOULD APPRECIATE IT. PLEASE ANSWER ME AS SOON AS POSSIBLE.

FIRST PART OF COMPLAINT JUST IN CASE IT DID NOT GO THRU THE FIRST TIME. DEAR SIRS, I'M WRITING TO YOU ON BEHALF OF THE OWNER OF THIS VEHICLE. THEY HAVE CONTRACTED ME AS A VEHICLE ACCIDENT RECONSTRUCTIONIST IN PUERTO RICO. I NEED TO KNOW IF YOU HAVE MADE ANY INQUIRIES IN THE FUEL DELIVERY AND PROPULSION SYSTEM. MY CONCERN IS THAT THIS TOYOTA, LEXUS AND HONDA VEHICLES THAT I KNOW OF SO FAR, ARE HAVING SOME KIND OF SUDDEN ACCELERATION ISSUES AND THE COMPUTER DOES NOT CATCH THE PROBLEM. THIS ACCELERATION SURGES THAT I HAVE FOUND OUT ABOUT, ALL HAVE OCCURRED AROUND HIGH ELECTRICITY AREAS. SO FAR THAT I KNOW OFF, THREE OF THESE SURGES HAVE OCCURRED NEXT TO THE ELECTRICAL PLANT CENTER IN PALO SECO PUERTO RICO AND ONE CAUSED TWO DEATHS. THE OTHER ONE IS THE ONE I'M REPRESENTING WHICH OCCURRED IN THEIR HOME TWICE. THE FIRST TIME WAS ABOUT A MONTH BEFORE THIS ACCIDENT BUT THE DRIVER HAD THE CHANCE TO CONTROL THE VEHICLE AND NOTHING HAPPENED. AT THAT TIME THE VEHICLE WAS TAKEN TO THE DEALER FOR A CHECKUP AND NOTHING STRANGE SHOWED ON THEIR SYSTEM.
