AFTER VEHICLE POWERED OFF AND AND AFTER COUPLE OF HOURS LATER, THE BREAK PEDAL GETS VERY STIFF. SO, TREMENDOUS FORCE NEEDS TO APPLY TO START TO ENGINE. AFTER AROUND 600 MILES OF DRIVING THIS NEW VEHICLE, THIS PROBLEM HAPPENED. MY WIFE IS PRIMARILY DRIVING THIS VEHICLE. AND THUS SHE IS GETTING KNEE PAIN ISSUE TO STIFF BREAK PEDAL. ACURA CONFIRMED THIS IS KNOWN ISSUE BUT THEY DENIED TO FIX IT AS INDICATED IN THE ATTACHED DOCUMENT.
THE ANTI COLLISION SYSTEM IS DEFECTIVE AND IT'S PUTTING MY FAMILY AT RISK. IT SLAMS ON BREAKS BY ITSELF WITHOUT ANY OBSTACLE IN FRONT. IT STARTED HAPPENING MORE AND MORR FREQUENTLY. CALLED THE ACURA DEALRSHIP AND THEY CLAIM IT'S NORMAL AND THE CAR WOULD BREAK FOR ANY PERCEIVED OBSTACLE IN FRONT OF IT.
BREAKING LIGHT GOES ON AND THE BRAKE GETS STUCK AND MAKES A GRASPING NOISE LIKE SOMETHING IS GRINDING AND THE PEDAL IS STUCK DOWN.
