2013 BUICK REGAL Structurebody Problems

I'VE HAD FOR THE LAST FEW YEARS HAD ISSUES WITH MY 2013 BUICK REGAL TURNING OFF WHILE DRIVING CAUSING A FEW ACCIDENTS THAT HAS NEARLY CAUSE ME MY LIFE. THE CAR HAS HAD MULTIPLE ELECTRICAL ISSUES I'VE TRIED GETTING FIXED AND I'VE DEALT WITH DAMAGE TO MY VEHICLE DUE TO THIS. CAR HAS TURNED OFF ON ME WHILE IN MOTION. I'VE REPLACED THE BATTERY AND I'VE SPENT SEVERAL 1,000S OF DOLLARS TRYING TO GET IT REPLACED. *TR

I PULLED INTO A PARKING SPACE AND STOPPED. I TOOK MY FOOT OFF THE BREAK AND THE CAR LURCHED FORWARD, RUNNING INTO A WOODEN RAIL FENCE. THE FENCE WHICH WAS OLD, WAS KNOCKED DOWN. IT ALL HAPPENED SO QUICKLY, I WASN'T SURE IF I HAD HIT THE ACCELERATOR. TWO DAYS LATER I MADE A NORMAL STOP IN TRAFFIC. AFTER BREAKING, THE CAR LURCHED FORWARD. I PUSHED ON THE BREAK PEDAL TO STOP THE CAR, BEFORE IT COULD HIT THE CAR IN FRONT OF ME. THIS TIME I WAS SURE MY FOOT HAD NOT HIT THE GAS PEDAL. I AM NOW GIVING THE CAR EXTRA BREAKING DISTANCE. IN EITHER CASE, I DIDN'T NOTICE IF THE TACHOMETER INCREASED RPM OR NOT, THOUGH WITH THE SUDDEN ACCELERATION RPM MUST HAVE INCREASED.

DAMAGE ON DRIVE SIDE OF REAR BUMPER AND TRUNK LIGHT, INCLUDING TRUNK DAMAGE TO THE VEHICLE. *TR
