I GOT INTO 2 ACCIDENTS IN 3 DAYS WHILE PARKING INTO OR OUT OF A PARKING SPACE. THE FIRST ACCIDENT 07/04/2020, MY CAR WAS PARKED IN A PARKING LOT. I PLACED THE CAR IN REVERSE AND SUDDENLY IT ACCELERATED AND THE BRAKES FAILED TO WORK. MY VEHICLE ONLY STOPPED AFTER CRASHING INTO THE CAR BEHIND ME. THE SECOND ACCIDENT HAPPEN 7/7/2020 WHILE PULLING FORWARD INTO A PARKING SPACE, THE CAR SUDDENLY ACCELERATED AND BRAKES FAILED TO WORK AGAIN. I CRASHED INTO A CEMENT POLE WHICH STOPPED MY VEHICLE. I COULDN'T FIGURE OUT WHY THESE 2 DANGEROUS ACCIDENTS OCCURRED? MY VEHICLE WAS JUST REPAIRED OVER A WEEK BC THE CHECK ENGINE LIGHT AND TRACTION CONTROL LIGHT CAME ON. THE MECHANIC SAID THE PROBLEM WAS FROM A CATALYTIC CONVERTER THAT WAS CLOGGED, SO HE REPLACED IT WITH A NEW OEM PART. THE AIR CONDITIONER WAS BLOWING HOT ALSO, SO THE MECHANIC REPLACED THE AIR COMPRESSOR IN CAR AT THE SAME TIME. I WISH TO FILE A REPORT BASED ON THE "SUDDEN UNINTENDED ACCELERATION" DANGER.
