WHILE ON THE HIGHWAY STUCK IN TRAFFIC, IT WAS A STOP AND GO AT VERY SLOW SPEEDS. WHEN RESUMING THE ACCELERATION (WHILE IN NORMAL FROM THE DNA ). I SLOWLY BEGAN TO ACCELERATE, WHEN I PRESSED THE BREAKS THE FEELING ON THE PEDAL WAS ABNORMAL AND THE CAR DID NOT STOP CAUSING ME TO HIT THE VEHICLE IN FRONT OF ME. IT FELT AS IF THE BREAKS DID NOT FULLY ENGAGE, THE CAR JUST KEPT GOING WHILE ONLY PRESSING THE BREAKS WHICH I REPEAT AGAIN FELT AS IF THEY DID NOT FULLY ENGAGE. ALL THIS HAPPENED WHILE GOING AT A VERY LOW SPEED NO MORE THAN 20MPH. NO ONE WAS HURT AS ALL THIS HAPPENED AT A VERY SLOW SPEED. HOWEVER IT SCARES ME TO DRIVE THE VEHICLE NOW. NOT TOO LONG AGO I HAD IT IN THE SERVICE WHERE THEY PERFORMED A FAULT WITH THE SOUND SYSTEM AND A MISALIGNED HOOD. I HAVE ALSO FELT THE BREAKS ACTING FUNNY WHILE COMING TO A STOP LIGHT PER SAY, IT TAKES A WHILE FOR THE CAR TO FULLY STOP WHETHER A SOFT PRESS ON THE PEDAL OR A HARD ONE. THERE SEEMS TO BE A "DEAD POINT" WHEN STEPPING ON THE BREAK PEDAL AS WELL. WE WERE ABLE TO DRIVE THE CRUSHED GIULIA TO THE NEAREST SHOP. THE OTHER PARTY WHO WAS HIT DIDN'T SUFFER MUCH DAMAGES, ON MY CAR, BOTH HEADLAMPS BROKE, HOOD CRUSHED INWARDS AND THE BUMPER IS TRASHED. I HAVE EXPRESSED MY CONCERN WITH ALFA ROMEO BUT NEVER RECEIVED A REPLY. ON A SIDE NOT I HAVE BEEN HAVING CONSTANT ELECTRICAL PROBLEMS POP UP RANDOMLY SINCE I PURCHASED THE VEHICLE IN 2017. ALL OF WHICH HAS BEEN ADDRESSED BY THE ALFA ROMEO DEALERSHIP, HOWEVER IT HAS BEEN IN THE SERVICE DR
