2006 MAZDA MPV Structurebody Problems

I OWN A 2006 MAZDA MPV. ON SEPTEMBER 26, MY WIFE HAD AN ACCIDENT WHILE ENTERING IN OUR HOME DRIVE WAY, WITH THE BRAKE PEDAL DEPRESSED, THE VEHICLE CONTINUED TO ACCELERATE AND STRUCK THE GARAGE DOOR AND CRASHED AGAINST THE INTERNAL WALL THAT DIVIDE THE GARAGE FROM THE KITCHEN. WE DID NOT REPORTED THE ACCIDENT TO THE POLICE OR THE INSURANCE TO AVOID FURTHER INCREASE IN THE QUOTES INSURANCE BUT OUR NEIGHBORS SAW THE ACCIDENT. WE HAD TO HIRE A SPECIALIZED DOOR COMPANY TO REPLACE THE GARAGE DOOR AND A HANDYMAN TO FIX THE GARAGE SIDE AND THE KITCHEN SIDE. THE ESTIMATED COST FOR THE CAR REPAIR IS $2,000.00, NEW GARAGE DOOR $1,175.00 AND THE WALL $250. A FEW DAYS AFTER WE BOTH THIS CAR, I HAD THE SAME PROBLEM AT THE AUTO PARTS PARKING LOT WITHOUT CONSEQUENCES, JUST THE TERRIBLE MOMENT IN WHAT YOU FEEL THAT YOU CAN'T STOP...
