2009 CHEVROLET COBALT SS Complaints

I HAVE A 2009 COBALT SS THAT I BOUGHT NEW AND BEFORE I HAD THE FIRST OIL CHANGE AT 5000 MILES I WAS HAVING BRAKE SQUEALING THE DEALER LOOKED AT IT AND SAID ITS NORMAL IV HAD IT AT 2 DIFFERENT DEALERS SEVERAL TIMES AND NOTHING HAS BEEN DONE, I NOW HAVE 26000 MILE AND NO BACK BRAKES ROTORS ARE BADLY SCORN, SOMETHING HAS TOO BE DONE WITH THIS. *TR

WITH JUST OVER FIVE THOUSAND MILES ON THE CAR THE REAR BRAKE PADS ARE GRINDING. THE OF THE REAR ROTORS HAS DEEP GROOVES. WHEN IT IS WET ITS EXTREMELY HARD TO STOP. I ALMOST HIT THE VEHICLE IN FRONT OF ME WHEN I WAS ON AN EXIT RAMP BECAUSE THE VEHICLE WOULDN'T STOP. *TR

BOUGHT MY 09 COBALT SS WITH LESS THAN 1,000 MILES AND MY REAR BRAKES SQUEAL AND GRIND HORRIBLY WITH ONLY 11,500 MILES. *TR

HAD TIRES ROTATED AT DEALER, THEY FOUND REAR BRAKE PADS WORN OUT COMPLETELY AND ROTOR SCORED AFTER ONLY 6000 MILES. HAVE FOUND MANY OTHER OWNERS WITH SAME PROBLEM. DEALER CLAIMS IT WAS CAUSED BY DRIVING WITH THE E BRAKE ON. THEY REFUSED TO REPAIR UNLESS PAID, CLAIMS WARRANTY DOES NOT COVER PADS WEARING OUT UNUSUALLY TOO SOON. *TR

WHILE DRIVING DOWN THE HIGHWAY, DOING APPROXIMATELY 60 MPH, MY 2009 CHEVROLET COBALT SS SHED IT'S INNER LEFT REAR BRAKE PAD, CAUSING THE BRAKE PEDAL TO SINK TO THE FLOOR, WHEN PRESSED, TO NO AVAIL. LUCKILY, NO ACCIDENT RESULTED. UPON INSPECTION, THE LEFT INNER PAD WAS COMPLETELY GONE, WHILE THE LEFT OUTER, AND BOTH RIGHT REAR PADS WERE WELL WITHIN NORMAL LIMITS. THE GM DEALERSHIP REFUSED TO FIX THIS PROBLEM, STATING THAT IT WAS "NORMAL WEAR AND TEAR". A MECHANIC AT THE DEALER WHISPERED TO ME THAT IT WAS A FAILURE THAT WAS LIKELY CAUSED BY THE CALIPER NOT RETRACTING PROPERLY, AND, WHILE IT SHOULD BE COVERED UNDER WARRANTY, THERE WAS NOTHING HE COULD DO. THIS FAILURE OCCURRED AT ABOUT 12,000 MILES, WHILE THE VEHICLE WAS ONLY 4 MONTHS OLD. THE REAR BRAKE PADS, AS WELL AS, THE LEFT REAR ROTOR HAD TO BE REPLACED. *TR

I HAVE A 2009 CHEVY COBALT SS. AT APPROX. 4000 MILES THE CAR WAS TAKEN TO THE LOCAL CHEVY DEALER DUE TO THE REAR BRAKE ROTORS DEEPLY GROOVED. THE DEALER TURNED THE ROTORS AND REINSTALLED THE BRAKES. AT APPROX. 7000 MILES THE ROTORS ARE STARTING TO GROVE AGAIN. THE DEALER REPLACED THE ROTORS AFTER A LENGTHY CONVERSATION WITH ALOT OF RELUCTANCE. THE DEALER STATES AND HAS A BULLETIN FOR GMC THAT NOISE AND SQUEAL ARE TYPICAL WITH A HIGH PERFORMANCE BRAKE SYSTEM. PLEASE NOTE IT'S NOT THE SQUEAL THAT CONCERNS ME IT'S THE DEEP GROOVING OF THE REAR BRAKE ROTORS. ALTHOUGH IT HASN'T TURNED INTO A SAFETY PROBLEM YET IT IS A CONCERN. I HOPE YOU WILL INVESTIGATE THIS PROBLEM BEFORE IT BECOMES ANOTHER TOYOTA AND PEOPLE ARE HURT OR POSSIBLY KILLED BE CAUSE OF PREMATURELY GROOVING AND WEARING OF THE REAR BRAKES ON THIS CAR. *TR

REAR BRAKES WEARING OUT AFTER 4000-5000 MILES. NEW AT 0, CHANGED AT 5044, NOW BAD AGAIN AT 10,600 MILES. MANY MANY MORE PEOPLE REPORTING SAME THING AT WWW.COBALTSS.NET. *TR

2009 COBALT SS - REAR BRAKES WORN. THE DEALER HAS ORDERED NEW ROTORS BUT NOT PADS. *TR

480 MILES ROTORS REPLACED 1200 MILES BRAKES BAD AGAIN SQUEALING AND GRINDING I AM IN FEAR EVERYTIME I DRIVE IT OF BRAKE FAILURE THIS SHOULD BE BROUGHT TO THE ATTENTION OF CNN AND THE BBB. *TR

REAR DISC BRAKES ON MY 2009 CHEVROLET COBALT SS TURBOCHARGED HAVE FAILED AFTER ONLY 15,000 MILES. THIS HAS CAUSED A SIGNIFICANT SAFETY CONCERN. THE DISC BRAKES HAVE SINCE WORN INTO THE ROTORS, CAUSING PROPERTY DAMAGE. ON TWO OCCASIONS, I VISITED A CHEVROLET DEALERSHIP AND ASKED ABOUT THE SQUEAKING IN THE BRAKES. ON BOTH OCCASIONS, I WAS TOLD THAT "UNDER CERTAIN...CONDITIONS, OCCASIONAL BRAKE SQUEAL, SQUEAK, OR OTHER NOISE MAY BE HEARD..."
