2007 Infiniti G35 Brakes Problems

WHEN I PRESS BRAKE PEDAL DOWN THE BRAKE STARTS TO SLOW THE CAR, BUT ALL OF THE SUDDEN THE BRAKE IS COMPLETELY TO THE FLOOR. THE CAR JUST KEEPS GOING. BRAKES COMPLETELY GONE. I HAD TO USE THE E BRAKE TO STOP THE CAR FROM SLAMMING INTO ANOTHER CAR IN AN INTERSECTION. I WAS ABLE TO PULL THE CAR OFF AND ON TO A SIDE ROAD WHERE I CALLED AAA FOR A TOW. THAT UNFORTUNATELY WAS NOT THE FIRST TIME THIS HAS HAPPENED. THE FIRST WAS IN A DRIVE THRU. I WENT TO STOP AT THE WINDOW AND LITERALLY JUST KEPT ROLLING LIKE I WAS NOT EVEN PRESSING THE BRAKE. I STARTED TO PANIC AND FRANTICALLY PUMPING BRAKE WHEN FINALLY I SOMEHOW HAD BRAKES AGAIN AND THE CAR CAME TO A SUDDEN STOP. VERY SCARY. I REPORTED THIS ISSUE TO INFINITI AND THE LADY ON THE CHAT LIVE SAID SORRY THERE'S NOTHING WE CAN DO FOR YOU. I HAVE READ BLOGS AND BLOGS OF PEOPLE HAVING THE SAME ISSUE I DON'T GET HOW THIS IS LEGAL AND NOT RECALLED. I HAD MY CHILD WITH ME THE DAY I USED THE E BRAKE HE WAS SO SCARED HE DIDN'T WANT TO RIDE IN THE CAR AGAIN.

WHILE DRIVING I EXPERIENCE EXTREME VIBRATIONS, COMING FROM THE RIGHT SIDE OF THE CAR TRAVELING AT OR ABOVE 65 MPH. ONCE I REDUCED THE SPEED VIBRATIONS DID NOT STOP, BUT IT WAS MANAGEABLE. I HAD MY TIRES BALANCED AND ROTATED THE NEXT DAY, THINKING THAT WOULD FIX IT. BUT ONCE AGAIN IT STARTED, MY VEHICLE HAS NEW TIRES AND I HAD THE VEHICLE ALIGNED. AFTER DRIVING THE CAR A COUPLE MORE DAYS, THE VIBRATIONS STOP BUT DAYS LATER IT BEGAN AGAIN. I WAS FED UP, SO I TOOK VEHICLE TO MY MECHANIC AND FOUND THAT THE RIGHT REAR CALIPER HAD GOTTEN STUCK AND IT WOULD NOT RETURN TO ITS PROPER PLACE AFTER BRAKES WERE DEPRESS, THUS MAKING THE CAR VIBRATE AFTER DRIVING ABOVE 65 MPH. I HAD THE CALIPERS REPLACED, BUT NOW THE LEFT SIDE IT VIBRATING AS WELL. THE VEHICLE HAD NO VISIBLE RUST OR PROBLEMS, PERHAPS CALIPER IS OR ARE DEFECTIVES AFTER ONLY 7 YEARS ON THE ROAD. *TR

THIS SAFETY CONCERN IS IN REGARDS TO THE BRAKES EVERY TIME I ACCELERATE ON THE BRAKES FROM SPEED THERE IS A VIBRATION CAUSING THE VEHICLE TO JERK. *TR

THERE WAS NO INCIDENT. MY CONCERN IS THAT A AUTOMOBILE SHOULD NOT HAVE TO HAVE NEW REAR BRAKES PADS AND REFINISHED ROTORS AT ONLY 20,000 MILES. I CONSIDER THIS SITUATION AS A SERIOUS DEFECT IN THIS PARTICULAR MODEL. I HAVE DRIVEN MANY CARS AND HAVE NEVER HAD TO REPLACE ANY BRAKE PARTS AS SOON. USUALLY, THE FRONT BRAKE WEAR FIRST. THE BRAKES WERE BECOMING VERY POOR AND I HAD TO HAVE THEM SERVICED FOR SAFETY REASON. I WOULD HOPE THAT YOU WOULD CHECK INTO THIS AS I REALLY FEEL THAT IT IS IMPORTANT THAT THE GENERAL PUBLIC IS AWARE OF THIS APPARENT DEFECT IN THE BRAKE SYSTEM ON THIS MODEL. THANK YOU.

PARKING BREAK DOES NOT HOLD CAR WHEN FULLY ENGAGED, EVEN ON A VERY SLIGHT HILL. THIS HAS ALWAYS BEEN THE CASE, EVEN WHEN THE CAR WAS NEW.
