2009 CHEVROLET COBALT SS Complaints

I BOUGHT A NEW 2009 COBALT SS TURBO ON APRIL 15TH 2009, ABOUT 8 MONTHS LATER MY REAR BRAKES HAD GROOVES IN THE ROTORS AND MY LEFT REAR CALIPER WAS STICKING. THIS CAUSED VERY POOR BRAKING PERFORMANCE. I TOOK THE CAR INTO THE DEALER AND THEY HAD TO REPLACE THE LEFT REAR CALIPER, NEW REAR PADS AND THEY MACHINED THE ROTORS. I HAVE HAVE SINCE HAD TO TAKE THE VEHICLE BACK INTO MY DEALER DUE TO A RING OF RUST BUILDING UP ON THE LEFT REAR ROTOR. I HAVE REASON TO BELIEVE THAT THE REAR BRAKES ON THESE CARS HAVE DEFECTIVE PARTS FROM THE FACTORY. THERE ARE A LARGE NUMBER OF OTHER 2008-2010 COBALT SS OWNERS HAVING THESE ISSUES.

2009 CHEVY COBALT SS 4DOOR CAR HAS ONLY BEEN PUT UNDER STANDARD DRIVING CONDITIONS CITY/HIGHWAY AND BEFORE 20000 MILES THE REAR BRAKE ROTORS WERE GROVED AND WARPED BEYOND REPAIR AND THE INSIDE REAR BRAKE PAD WAS DOWN TO METAL. THE OUTSIDE PAD STILL HAD OVER 70% LIFE LEFT ON IT BUT WAS GROVING THE ROTOR ALSO. FRONT BRAKES ARE FINE WITH NO ISSUES.

REAR BRAKES GRINDING AND SQUEALING I AM IN FEAR OF MY LIFE WITH ALL THE CAR RECALLS BRAKES ARE NOT SOMETHING TO MESS WITH...I AM AFRAID TO DRIVE MY NEW GM COBALT SS FOR FEAR OF AN ACCIDENT AND FAILING BRAKES ! *TR

2009 COBALT SS WITH DISC REAR BRAKES. MILEAGE 16588. THE REAR BRAKES ARE GETTING EXTREMELY SCORED (LOOK LIKE A RECORD WITH GROVES) AND IT SOUNDS LIKE THE PARKING BRAKE IS DRAGGING. I NOTICED THIS STARTED 2 DAYS AGO WHEN IT FELT LIKE THE PARKING BRAKE WAS STILL ENGAGED WHEN I WENT TO PULL OUT OF A PARKING SPOT. THE REAR OF THE CAR SQUATTED DOWN, TO ME INDICATE THE BRAKE WAS HUNG UP. THEN I HEARD A "TWANG" SOUND FOLLOWED BY A POP. IT SOUND LIKE A BRING THAT WAS HUNG UP FINALLY LET LOOSE. AFTER THAT INCIDENT I STARTED TO NOTICE THAT AT SPEED LESS THAN 10 MPH YOU GET A NOTICEABLE SCRAPING SOUND FROM THE REAR BRAKES. IT SOUND SIMILAR TO WHEN YOU TURN ROTORS ON A BRAKE LATHE. *TR

HAD ONLY 2000 MILES ON MY 09 COBALT AND REAR BRAKES STARTED TO SCORE FROM INNER BRAKE PADS. DEALERSHIP WOULDN'T FIX DUE TO BULLETIN GM SENT OUT NOT TO REPLACE. HAD TO REPLACE BRAKE PADS ON OWN. CAR WOULD HAVE GRINDING NOISE FROM REAR BEFORE REPLACING BRAKE PADS. *TR

REAR BRAKES ON 2009 COBALT SS T/C ONLY 1500 MILES ON THE CAR AND REAR ROTORS ARE ABSOLUTELY TRASHED. OUTSIDE PAD LOOKS GOOD INSIDE PAD IS DOWN TO THE MEDAL. *TR

REAR BRAKES ARE WEARING DOWN UNUSUALLY FAST, PARTICULARLY ON THE INSIDE SURFACE WHERE IT IS HARD TO SEE. BRAKE ROTORS ARE GROOVING SEVERELY. DEALER HAS RESURFACED THE ROTORS AND SANDED THE PADS ONCE ALREADY LESS THAN 4000 MILES AGO, AND NOW THEY WILL HAVE TO BE REPLACED. CLEARLY, FAILING BRAKES IS A SERIOUS ISSUE. *TR

THE REAR BRAKES STARTED SQUEAKING REALLY BADLY AT 5000 MILES ON MY NEW 2009 CHEVY COBALT SS. WHILE PERFORMING A TIRE ROTATION, I INSPECTED THE BRAKES AND ROTORS FOR UNUSUAL WEAR. I NOTICED TWO REALLY DEEP GROOVES/SCORES ON THE BACKSIDE OF THE DRIVER SIDE REAR BRAKE ROTOR. I TOOK IT TO THE DEALERSHIP WHERE THEY AGREED THAT WAS NOT NORMAL WEAR AND REPLACED THE ROTOR. THE BRAKES STILL SQUEAK BUT NOT AS BAD. IT IS UNFORTUNATE THOUGH THAT I HAVE TO DRIVE AROUND IN A NEW CAR AND AM EMBARRASSED TO COME TO A STOP WITH ALL THE SQUEALING. I WAS HANDED A TSB (#08-05-22-004) STATING THAT SQUEAKING BRAKES ARE NORMAL AND ARE NOT TO BE REPAIRED. I CAN ASSURE YOU THAT NO ONE TOLD ME TO EXPECT SUCH AWFUL NOISES FROM MY NEW CAR WITHIN THE FIRST FIVE MONTHS OF DRIVING IT. *TR

MY BRAKES VIBRATE AND HAVE DEEP GROOVES IN THEM AND I ALMOST GOT TURNED DOWN FOR REPAIRS BECAUSE THEY THOUGHT IT WAS FROM IMPROPER USE OF MY VEHICLE. *TR

2009 CHEVROLET COBALT SS. SEDAN. EXTREME REAR BRAKE PAD WEAR (70%) AND REAR BRAKE ROTOR DAMAGE AFTER ONLY 4000 MILES. WHY HAS NOTHING BEEN DONE ABOUT ALL THE COMPLAINTS REGARDING THIS SERIOUS ISSUE? I DO NOT ABUSE THE CAR AND DO NOT APPLY HARD BRAKES. I ONLY ENGAGE THE PARKING BRAKE WHEN THE CAR IS STOPPED AND PARKED. INVESTIGATE, RECALL AND REPAIR. *TR
