THE CAR WAS STOPPED ON A PARKING LOT EXIT RAMP. WHEN THE CAR AHEAD OF ME MOVED FORWARD I TOOK MY FOOT OF OF THE BRAKE SO I COULD MOVE FORWARD. WHEN I APPLIED THE BREAK TO STOP, THE BREAKS DID NOT WORK AND I HIT THE CAR IN FRONT OF ME.
OCTOBER 10TH, I WAS IN AN ACCIDENT WHERE I WAS LITERALLY AN ENTIRE CAR LENGTH BACK DRIVING WITH THE FLOW OF TRAFFIC AT 50-55 MPH, WHEN THE VEHICLE IN FRONT OF ME CAME TO AN ABRUPT STOP ON THE FREEWAY. I SLAMMED ON MY BRAKES BUT MY CAR SLID STRAIGHT INTO THE BACK OF THE VEHICLE IN FRONT OF ME. IT FELT AS IF MY BRAKES WERE NOT STOPPING MY CAR. I NOTICED THIS HAPPENING BEFORE ON A MAIN STREET AND I WAS TRAVELLING AT 45 MPH BUT I DID NOT THINK ANYTHING OF IT AT THE TIME.
IN FEBRUARY 2019 I PURCHASED A 2018 CHEVY IMPALA PREMIER, UPON DRIVING THE CAR I NOTICED THAT THE BRAKES WERE NOT WORKING LIKE MY 2018 CHEVY CAMARO BUT I CHUCKED IT UP TO THE CAR BEING HEAVIER AND PAID IT NO ATTENTION. FOR MONTHS I HAVE BEEN THINKING THAT MAYBE I JUST NEED TO GET USED TO THE BRAKES ON MY NEW CAR AND THAT IT WAS NOTHING. WHILE I DRIVE AT NORMAL SPEEDS (40 - 45 MPH) MY CAR SLID AN EXTRA 5- 10 FT MORE THEN IT IS SUPPOSED TO EVERY TIME. YESTERDAY WHILE BRAKING MY BRAKES JUST TOTALLY DID NOT RESPOND CAUSING ME TO HIT THE BACK OF ANOTHER DRIVER. I WAS DRIVING ABOUT 30 MPH LITERALLY JUST TURNING OUT OF A SHOPPING PLAZA WHEN THE ACCIDENT HAPPENED. I STARTED TO PRESS THE BRAKES ABOUT 50 METERS AHEAD AND MY CAR DID NOT BUDGE NOR DID IT BEGIN TO STOP IT CONTINUED TO DRIVE AT THE SAME SPEED UNTIL I PROMPTED TO TURN AND BRACED FOR THE COLLISION. I HIT THE BACK PASSENGER BUMPER AND THE SIDEWALK BRINGING MY CAR TO A HALT. THIS INCIDENT WHICH PROMPTED ME TO LOOK FURTHER BRUNG ME ONLINE TO SEE THAT THERE IS A RECALL FOR THE CHEVY IMPALA BRAKES WORKING IMPROPERLY. IT SAYS THAT IT IS ON SOME IMPALAS AND I BELIEVE THAT MINE IS ONE OF THEM.
