2009 CHEVROLET COBALT SS Complaints

I HAVE A 09SS/TC AND I HAVE A PROBLEM WITH MY BACK ROTORS WITH LINES AND GROOVES IN THEM. I ONLY HAVE 4000 MILES ON MY CAR NOW. I TOOK IT TO THE DEALERSHIP AT 3500 AND THE SHOP MANAGER ARGUED WITH ME THAT IT IS NORMAL WEAR AND TEAR AND THAT THE BACK BRAKES ARE "AGGRESSIVE" STYLE PADS. AND HE ARGUED THAT THE BACK DO MORE STOPPING POWER THAN THE FRONT. THEY HAVEN'T DONE ANYTHING ABOUT THIS PROBLEM YET AND I KNOW THAT MANY OTHER CARS OF THE SAME MODEL HAVE THIS PROBLEM. THE MAIN MECHANIC DID CONFIRM THAT IT ISN'T A NORMAL WEAR BUT SAID THAT THE CAR IS TOO NEW TO ANYTHING ABOUT IT. PLEASE HELP US OUT I REALLY DON'T WANT THIS TO CAUSE AN ACCIDENT OR FOR ME TO HAVE TO PAY FOR ALL NEW ROTORS AND PADS AT MY EXPENSE BECAUSE OF THEIR MESS UP. *TR

BOTH REAR ROTORS ARE HEAVILY SCORED ON THE INNER AND OUTER SIDES OF THE ROTOR. DEALER CALLS IT HANDBRAKE ABUSE. I NEVER KNEW THAT PULLING YOUR HANDBRAKE WHEN YOU PARK THE CAR WAS ABUSE. *TR

REAR BRAKES HAVE EXTREME GOUGING AFTER ONLY 7,000 MILES AND ARE STARTING TO SQUEAL AND YOU CAN TELL THEY ARE STICKING TO THE ROTORS AND NOT FULLY RELEASING WHICH CAN TURN INTO A BIG LIABILITY ISSUE. GM NEEDS TO REPLACE THE REAR ROTORS WITH A QUALITY PRODUCT THAT CAN WITHSTAND THE REAR PADS USED.... OR REALLY NEEDS TO CHANGE TO BREMBO ROTOR/CALIPER LIKE THE FRONT. *TR

PREMATURE REAR BRAKE WEAR. INNER ROTOR SURFACE HAS GROOVES AND UNEVEN PAD WEAR. NOTICED AT 4500 MILES. *TR

MY REAR BRAKES ON MY 2009 COBALT SS WITH JUST OVER 17000 MILES ON IT WERE COMPLETELY GONE WHEN I TOOK THE CAR TO THE DEALERSHIP ON TUESDAY JULY 28TH OF 2009. I FIRST NOTICED SOME UNUSUAL NOISE COMING FROM THE REAR OF THE VEHICLE AT AROUND 15000 MILES. AT FIRST THE NOISE WAS SPORADIC AND I WAS NOT CONCERNED WITH IT BUT IT SOON DEVELOPED INTO A CONSTANT FRICTION TYPE NOISE THAT COULD NOT BE IGNORED. AFTER LEAVING THE VEHICLE WITH THE DEALERSHIP ALL DAY THEY FOUND THE CAUSE OF THE PROBLEM. MY REAR BRAKES WERE METAL TO METAL WITH THE ROTORS. THE SERVICE EMPLOYEE ASKED ME IF I E-BRAKE SLIDE THE CAR, SINCE I WAS NOT EXACTLY FAMILIAR WITH THE TERM HE HAD TO CLARIFY ITS MEANING. I TOLD HIM I AM NOT AN E-BRAKE SLIDING KIND OF GUY AND ASKED HIM TO CHECK THE WARE ON THE TIRES IF HE DID NOT BELIEVE ME BECAUSE IT SOUNDS LIKE PERFORMING A MANEUVER LIKE THAT WOULD CAUSE THE TIRES TO HAVE BALD SPOTS. WE THE SERVICE PEOPLE COULD NOT FIND ANY BALD SPOTS THEY RULED THE BRAKE AS A DEFECT AND COVERED THEM UNDER WARRANTY. I JUST FIND IT UNUSUAL THAT THE REAR BRAKES WOULD DO THIS SO EARLY IN THE LIFE OF THE VEHICLE WHEN THE FRONT BRAKES LOOK LIKE THEY HAVE BARELY BEEN TOUCHED. IF I HAD BEEN TAKING A TURN OR HAVING TO BRAKE IN AN EMERGENCY I DON'T KNOW WHAT ALL COULD HAVE HAPPENED WHEN I HAVE REAR METAL TO METAL INSTEAD OF THE OEM BRAKE PADS TO PROTECT ME. *TR

WEARING OF REAR BRAKES. THIS INCLUDES DEEP SCORING OF THE ROTOR AND BRAKE PAD AS WELL AS LOUD GRINDING WHEN STOPPING. THIS HAS BEEN ONGOING SINCE 100 MILES. I AM NOW AT 5K MILES AND HAVE SEEN A FEW CARS WITH THE SAME PROBLEM. PADS AND ROTORS NEED TO BE REPLACED AND AN ALIGNMENT DONE. *TR

I BOUGHT A USED COBALT SS FROM A DEALER IN MEMPHIS ON JULY 15, AND DROVE IT HOME TO KANSAS, ABOUT 900 MILES. IT HAD ABOUT 3300 MILES ON IT, AND HAD BEEN IN GM FLEET SERVICE. IT NOW HAS 4600 MILES. THE REAR BRAKE ROTORS ARE SCORED BADLY ON BOTH SIDES, AND MY LOCAL DEALER WILL NOT DO ANYTHING FOR ME, CALLING IT "WEAR". IN MY OPINION, THIS IS AN UNACCEPTABLE WEAR RATE ON BRAKES, WHICH IS A SAFETY CONCERN. I HAVE BEEN IN TOUCH WITH A NUMBER OF OTHER COBALT SS OWNERS WITH SIMILAR PROBLEMS. *TR

BRAKE PAD FAILURE: AT ROUTINE SERVICE, 17,665 MILES, DEALER FOUND REAR, INNER BRAKE PADS EXCESSIVELY WORN. RIGHT PAD WAS GONE, ROTOR BEING SCORED. LEFT WAS LESS THAN 5% REMAINING. OTHER PADS WITHIN NORMAL LIMITS. REPLACEMENT PADS ARE NOT IN STOCK AT GM, BACK-ORDERED. *TR

MY 2009 COBALT SS HAS 10,800 MILES AND AT 7K MILES, THE REAR BRAKES BEGAN TO SQUEAK. YOU CAN FEEL THAT THE ROTORS IN THE REAR ARE GROOVED TERRIBLY, AND THE INSIDE OF THE REAR PADS ARE EVEN WORSE. THE CAR IS AT THE DEALER NOW GETTING THIS FIXED AFTER I HAD ALREADY TAKEN IT TO ANOTHER DEALERSHIP AND THEY WROTE IT OFF AS "WEAR AND TEAR". REAR ROTORS DO NOT GET WORN OUT IN 10K MILES. *TR

MY ORIGINAL COMPLAINT IS 10263782. I NOW HAVE TO HAVE THE REAR BRAKE PADS REPLACED AGAIN. WENT FROM NEW TO 3/32 IN LESS THAN 4000 MILES. IN LESS THAN 12,000 MILES THE REAR INNER PADS HAVE BEEN REPLACED TWICE AND THE ROTORS RESURFACED ONCE. *TR
