2013 Nissan Sentra Body & Structure Problems

THIS IS THE THIRD (3) TIME IT HAPPEN, NO BREAKES GOING DOWN MY STEEP DRIVEWAY. I LIVE IN A NEIGHABORHOOD WITH MANY HILLS AND IT HAS COME TO MY ATTENTION THE BRAKES DO NOT FUNCTION PROPERLY GOING DOWN A STEEP HILL. MY SPEED WAS NO MORE THAN 4MPH WHEN BRAKE FAILURE. *TR

I GOT SIDE-SWIPED ON MONDAY, AND ON WED A SECOND PERSON WAS IN MY BLIND SPOT WHILE I WAS TRYING TO MERGE TO THE RIGHT. I HAD MY SIGNAL LIGHTS ON, I LOOKED SEVERAL TIMES EACH TIME. THE ONLY REASON WHY I WAS ABLE TO AVOID THE 2ND ACCIDENT WAS BECAUSE I HEARD THE PERSON'S BRAKES SCREECH. THERE IS NO VISIBILITY OUT THE BACK REAR PASSENGER WINDOW. THE DOOR COMES UP SIGNIFICANTLY HIGHER (MAYBE 4-5 INCHES) THAN IN THE OLDER SENTRA'S. THE MIRROR DOES NOT ROTATE FAR ENOUGH TO THE RIGHT IN ORDER TO SEE IN TO THE BLIND SPOT. NO ONE RIDING IN MY BLIND SPOT CAN SEE MY BLINKING SIGNAL LIGHT. OVERALL THIS CAR IS DANGEROUS TO DRIVE. GETTING HIT ONCE AND ALMOST A SECOND TIME WAS SCARY. THIS HAPPENED ON A VERY BUSY HIGHWAY (495). THIS CAR NEEDS TO BE RECALLED. THE FLAWS ARE INHERENT TO THE POOR DESIGN OF THE VEHICLE. THE DOOR AND MIRRORS ARE DEFECTIVE. THESE ARE DESIGN FLAWS WHICH THE CONSUMER CAN'T FIX OR MAYBE UNAWARE OF DURING A SIMPLE TEST DRIVE. THIS CAR SHOULD NOT BE DRIVEN ON A HIGHWAY. *TR
