2009 CHEVROLET COBALT SS Complaints

TL*THE CONTACT OWNS A 2009 CHEVROLET COBALT SS. THE CONTACT STATED THAT WHEN TRYING TO DECELERATE HE NOTICED THAT THE BRAKES WOULD MAKE A LOUD SCRAPING NOISE. HE THEN INSPECTED HIS VEHICLE AND NOTICED THAT THE REAR ROTORS WERE MAKING THE NOISE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 3500.

FULL REAR BRAKE REPLACEMENT AT 17K. WARRANTY ONLY COVERED CALIPER REPLACEMENT. *TR

I LAST CHECKED MY BRAKES WHEN I TOOK OFF MY SNOW TIRES IN MARCH WITH 18,000 MILES ON MY CAR. EVERYTHING LOOKED FINE, FRONT AND REAR PADS LOOKED ALMOST NEW WITH PLENTY OF MEAT ON THEM. IN JULY, I NOTICED THAT THE REAR BRAKES WERE STARTING TO GROOVE, SO I MENTIONED THIS TO THE DEALER WHEN I WENT IN FOR A RECALL AND THEY RESURFACED THEM FOR ME (22,885 MILES). I ASKED ABOUT THE PADS AND THEY TOLD ME THAT THEY HAD LOOKED AT THEM AND THEY WERE FINE AND EVERYTHING LOOKED NORMAL. IN OCTOBER, I NOTICED THE GROOVING COMING BACK. I TOOK IT BACK TO THE DEALER, AND THEY CHARGED ME TO REPLACE THE REAR DISKS AND PADS AT 29,170 MILES (THEY DID THROW IN THE ROTORS FOR FREE DUE TO THE ABNORMAL WEAR). AFTER THE SERVICE, THEY GAVE ME THE OLD REAR PADS AS PER MY REQUEST. UPON RECEIVING THEM, I COULDN'T HELP BUT NOTICE THAT THE INNER REAR PAD, WHICH HAD BEEN WEARING IDENTICALLY TO THE OUTER REAR PADS WHEN I CHECKED AT 18,000 MILES, WERE WORN ALMOST TO THE BACKING PLATE! THE OUTER PADS STILL HAD 1/4" MATERIAL LEFT, SO IT SEEMED CLEAR THAT SOMETHING WAS NOT RIGHT. THE DEALER COULD FIND NO REASON FOR THIS WEAR AND STATED THAT EVERYTHING WAS NORMAL BESIDES THE BRAKE WEAR. IT SEEMS INCREDIBLE THAT A FRONT-HEAVY, FRONT-DRIVE CAR WOULD WEAR THROUGH ITS INNER REAR BRAKE PADS WHILE ITS FRONT PADS (WHICH DO MOST OF THE BRAKING) AND OUTER REAR PADS STILL HAVE PLENTY OF LIFE LEFT WITHOUT THERE BEING SOME KIND OF PROBLEM. I STILL HAVE THE PADS AND ALSO HAVE PICTURES. I AM CONCERNED THAT IF THESE PADS WEAR DOWN SO QUICKLY, I COULD BE PUT IN A SITUATION WHERE I UNEXPECTEDLY HAVE NO E-BRAKE AND COMPROMISED BRAKING ABILITY DESPITE FREQUENT INSPECTIONS. I AM ALSO CONCERNED THAT GM IS MORE INTERESTED IN SELLING ME PARTS THAN IN DIAGNOSING AND CORRECTING THE ROOT OF THE PROBLEM. I HAVE HEARD FROM THE BOTH CHEVY DEALERS AND OTHER OWNERS THAT THIS IS A SOMEWHAT COMMON PROBLEM WITH MY CAR, AND I WOULD LIKE TO SEE IT RESOLVED. THANK YOU. *TR

REAR BRAKES ON A 2009 COBALT SS TURBO SCORE AND GRIND WITHIN 10,000 MILES. YOU HAVE TO PUT AFTER MARKET BRAKES ON THE CAR. *TR

I PURCHASED MY 2009 CHEVY COBALT SS/TC IN EARLY JUNE OF 2010. IT WAS A GM CERTIFIED USED CAR. WHEN I INSPECTED THE CAR BEFORE PURCHASING I NOTICED THAT THE BRAKES WERE HEAVILY WORN AND I LET THE SALESMEN KNOW ABOUT IT. HE TOLD ME THAT THERE WAS ALMOST 70% LEFT ON THE PADS AND EVERYTHING CHECKED OUT FINE . SO I DID THE DUMBEST THING I COULD DO AND TOOK HIS WORD FOR IT. AFTER ABOUT 5 MONTHS AND 4000 MILES LATER MY REAR BRAKES START MAKING A SCRAPING NOISE WHILE IN REVERSE AND WHILE LIGHT BRAKING AROUND CORNERS MOSTLY OUT OF THE PASSENGER SIDE.. I TOOK IT IN FOR MAINTENANCE EXPECTING SOME KIND OF MANUFACTURER DEFECT BUT INSTEAD I'M ACCUSED OF BAD DRIVING AND LETTING MY E-BRAKE DRAG. THE ISSUE WAS THAT THE REAR CALIPERS WERE STICKING AND NOT RETRACTING PROPERLY AND THE PISTONS INSIDE WERE BENT CAUSING UNEVEN PAD WEAR. BOTH SIDES MOISTURE BOOTS ON THE PISTONS LOOKED LIKE THEY WERE PINCHED AND BROKEN DURING THE FACTORY INSTALLATION. SO NOW HERE I AM WITH A BILL FOR ALMOST $1000 DOLLARS FOR REAR PADS, ROTORS AND CALIPERS AND ON A CAR THAT IS JUST OVER 2 YEARS OLD WITH ALMOST 2 YEARS ON A FACTORY BUMPER TO BUMPER WARRANTY. I'M SORRY BUT THE CALIPERS TO ME ARE A MECHANICAL DEFECTED PART AND SHOULD BE COVERED UNDER WARRANTY. *TR

I HAD EXTREMELY PREMATURE BACK BRAKE WEAR ON MY 2009 COBALT SS TURBOCHARGED. *TR

REAR BRAKES WORE TOO QUICKLY FOR A FRONT WHEEL DRIVE CAR THAT ONLY HAVE 10,000 MILES ON IT. *TR

TL*THE CONTACT OWNS A 2009 CHEVROLET COBALT SS. THE CONTACT STATED THAT WHILE DRIVING AT HIGHWAY SPEEDS, THE FRONT AND REAR BRAKES PULSATED WHEN THEY WERE DEPRESSED AND THE STEERING WHEEL VIBRATED. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHO STATED THAT THERE WAS NOTHING WRONG. THE VEHICLE HAD NOT BEEN REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 16,000.

MY REAR BRAKES ON MY 09 COBALT SS ARE WEARING UNEVENLY. MY RIGHT SIDE REAR BRAKE PADS ARE COMPLETELY USED UP AND AS A RESULT HAVE BEGUN TO GRIND ON TO THE ROTORS AND CAUSED THEM TO FORM PITS, AND OR GROOVES. VERY DISAPPOINTING. *TR

THIS HAS BEEN AN ONGOING PROBLEM FOR OVER A YEAR NOW. I TAKE MY VEHICLE TO THE DEALER AND TELL THEM THE REAR BRAKES ARE LOCKING UP AND THEY RESPOND WITH "THIS IS CAUSED BY DRIVER ABUSE, YOU HAVE BEEN POWERSLIDING IT" I HAVE HAD IT TO THREE DIFFERENT DEALERS. THE REAR BRAKES HAVE BEEN REPLACED 3 TIMES WITHIN 9 MONTHS AND ARE NOW NEEDED AGAIN. CHEVROLET STATES THEY ARE NOT WILLING TO FIX THE PROBLEM. *TR
