Owner Complaints (4)
Your brake pedal required excessive force to stop the vehicle while reversing, and the brakes failed to respond properly even when pressed hard. When you shifted to drive, the vehicle continued rolling forward uncontrollably despite pressing the brake pedal, forcing you to steer into a curb to avoid hitting a building. A mechanic diagnosed a faulty ABS module with low voltage communication issues as the cause, and the vehicle was not repaired.

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.
