“I WAS TRAVELING AT ABOUT 25 - 30 MPH WHEN WITH OUT WARNING MY 2009 CHEVY COBALT BEGAN TO SPIN IN THE MOST VIOLENT SPIN I HAVE EVER BEEN IN A VEHICLE. THE BRAKES WERE NOT STOPPING ME THE REAR OF THE CAR THEN SLID AROUND AND SLAMMED MY CAR INTO A POST OR CHAIN LINK FENCE HITTING IT HARD.THE FRONT PASSENGER DOOR WAS CREASED DOWN THE WHOLE SIDE, THE FRONT QUARTER PANEL WAS ALL RIPPED UP AND THE FRONT PASSENGER HEADLIGHT WAS COMPLETELY SMASHED AND BROKEN. WHEN THE CAR FINALLY STOPPED MY HAND WAS TWISTED IN THE STEERING WHEEL WHILE THE CAR WAS SPINNING AND THE FORCE OF THE CAR HITTING SPRAINED MY BACK. NO AIR BAGS WERE SET OFF AND I WAS BROUGHT TO THE ER BY AMBULANCE. I HAVE BEGUN TO HAVE PROBLEMS WITH MY IGNITION SINCE THIS ACCIDENT. MY KEY GETS STUCK IN THE ACCS POSITION AND I CAN NOT MOVE IT EITHER WAY. I HAVE TO WAIT UNTIL THE CAR SITS FOR A WHILE SOMETIMES HOURS BEFORE IT WILL UNLOCK. VERY SCARED TO DRIVE IN THIS CAR NOW. *TR”

“AS I WAS DRIVING DOWN THE STREET TO TURN INTO MY PARKING LOT I STARTED TURNING THE WHEEL LEFT WHEN I TURNED MY STEERING WHEEL AND BRAKES LOCKED UP AND DROVE OVER THE CURB OF MY APARTMENT COMPLEX CAUSING MY WHOLE RIGHT SIDE OF MY CAR $1300.00 WORTH OF DAMAGE THIS IS THE SECOND TIME THIS HAS HAPPENED TO ME FIRST TIME NO DAMAGE WAS DONE THAT WAS BACK IN OCTOBER. *TR”

“THE REAR BRAKES FAILED ON MY CAR AT AROUND 28,000 MILES. AS SOON AS I GOT THE NEW ONES INSTALLED THEY STILL ARE TERRIBLE, I DO NOT UNDERSTAND WHY THERE WOULD BE SUCH BRAKES THAT FAIL SO EARLY AND COULD CAUSE HARM TO PEOPLE. THERE NEEDS TO BE A RECALL ON THESE BRAKES, THEY ARE ENTIRELY TOO UNSAFE. *TR”

“TL* THE CONTACT OWNS A 2009 CHEVROLET COBALT SS TURBO. THE CONTACT STATED HIS REAR BRAKE PADS WERE PREMATURELY WEARING OUT RAPIDLY. THE ROTORS AND BRAKE PAD NEVER MADE ANY NOISE ALERTING THE CONTACT THERE WAS SOMETHING WRONG. WHEN THE VEHICLE WAS BEING SERVICED THE MECHANIC SHOWED HIM HOW THE ROTORS AND BRAKE PADS WERE WORN. THE VEHICLE WAS REPAIRED. THE FAILURE MILEAGE WAS 31,000 AND THE CURRENT MILEAGE WAS 40,000.”

“WHEN BRAKING SOFTLY, REAR BRAKES MAKE A LOUD NOISE AND I'VE STARTED TO NOTICE SLIGHTLY UNEVEN WEAR ON ONE OF THE REAR BRAKE PADS. ALSO OCCASIONALLY WHILE MOVING IN REVERSE WITH FOOT BRAKES APPLIED I CAN HEAR A VERY VERY LOUD SOUND SLIGHTLY DIFFERENT AND WAY LOUDER THEN THE SOUND WHEN MOVING FORWARD. *TR”
