I WAS PARKING MY MAZDA CX5 IN A SPOT AT A SHOPPING CENTER AND WHEN I TOUCHED THE BRAKE WITH MY RIGHT FOOT AND WENT TO SHIFT CAR INTO PARK, IT SUDDENLY ACCELERATED FULL SPEED, MAKING A VROOM SOUND, JUMPING THE CURB AND SMASHING INTO A BRICK POST (LUCKILY I HIT THE POST AND NOT A PERSON!). I DON'T KNOW IF IT'S A TRANSMISSION, BRAKE OR ACCELERATOR ISSUE - BUT THERE IS DEFINITELY SOMETHING WRONG. I DID NOT HIT THE ACCELERATOR INSTEAD OF THE BRAKE. AT FIRST I THOUGHT IT MUST BE ME, SOMEHOW, SOMEWAY, HITTING THE ACCELERATER BUT I NEVER REALLY BELIEVED THIS. TODAY, APRIL 26, 2019, THE SAME THING HAPPENED! LUCKILY, THIS TIME THE CAR JUMPED THE CURB AND I HIT A TREE, LEAVING A SMALL DENT IN MY HOOD. AGAIN I HEARD THAT VROOM SOUND, AND JUST THOUGHT - OH NO, NOT AGAIN!
