2009 CHEVROLET COBALT SS Complaints

A TERRIBLE GRINDING COMING FROM REAR BRAKES. THE BRAKES WEAR OUT TOO QUICKLY (AND THE ROTORS ARE BEING SCORED AT 100MILE-20,000MILE CARS) ALSO INSIDE REAR PADS START TO GET NOISY. *TR

THE STOCK ROTORS ON MY CAR STARTED GETTING SEVERELY WARPED WITHIN THE FIRST 3-4 MONTHS OF OWNING THE CAR. THE CAR WAS BRAND NEW WHEN I PURCHASES IT. I REPLACED THE BRAKES AFTER OWNING THE CAR FOR 10 MONTHS AND THE CAR HAD ABOUT 14,000 MILES. I SHOWED THE DEALER THE ROTORS AND THEY RESURFACED THEM. I'VE BEEN DRIVING THE CAR WITH NEW BRAKES SINCE JUNE 2010, THE NEW BRAKES ARE ALREADY SQUEAKING AND ROTORS HAVE SEVERE GROOVES ON THEM. I PURCHASED THE CAR JUNE 2009 BRAND NEW. *TR

UNEVEN AND EXCESSIVE WEAR ON THE REAR BRAKE PADS AND ROTORS. WHEN THE DEALERSHIP PULLED THE PADS THERE WHERE CHUNKS OF METAL THAT APPEARED TO BE ROTOR MATERIAL EMBEDDED IN THE PADS. *TR

I BOUGHT A 2009 CHEVY COBALT SS USED WITH 9000 MILES ON IT. FROM THE DAY I BOUGHT IT I CONSISTENTLY HEARD REAR BRAKE NOISE WHENEVER I STOPPED THE CAR. THERE IS EXCESSIVE PAD WEAR ON THE REAR BRAKES AT 11000 MILES NOW. WAY TOO MUCH WEAR THAN NORMAL. DEEP SCORING IN THE ROTORS. TOOK THE CAR TO THE DEALERSHIP I PURCHASED IT FROM AND THEY RESURFACED THE ROTORS BUT THE PROBLEM WAS STILL THERE AFTER I DROVE THE CAR HOME FROM THE SHOP. SO FAR NOTHING HAS BEEN DONE TO CORRECT THIS PROBLEM BY THE DEALERSHIP OF CHEVY. *TR

HAVE 2009 CHEVY COBALT SS AND HAS HAD TO TURN MY REAR ROTORS FOR THE 5TH TIME SINCE I GOT THIS CAR BRAND NEW, AT 36,000 MILES NOW. *TR

MY VEHICLE IS A 2009 CHEVROLET COBALT SS COUPE PURCHASED NEW IN MARCH OF 2009. AFTER 15,000 MILES (ABOUT A YEAR'S WORTH OF DRIVING), THE REAR BRAKE ROTORS WERE PITTED AND SCORED, AND WHEN THE BRAKES WERE APPLIED A METAL-ON-METAL GRINDING NOISE WOULD OCCUR. ALSO, AFTER GETTING WET FROM DRIVING IN THE RAIN, THEN ALLOWING TO VEHICLE TO REST FOR A SHORT PERIOD OF TIME, ENOUGH RUST WOULD BUILD UP ON THE REAR BRAKES THAT A COPIOUS AMOUNT OF THROTTLE WOULD BE NEEDED TO BREAK FREE THE PADS FROM THE ROTORS TO MOVE THE VEHICLE FORWARD. AFTER TAKING THE CAR TO THE SELLING DEALER FOR INSPECTION/REPAIR, I WAS TOLD THIS PART WAS A WEARABLE ITEM AND NOT COVERED UNDER MY MANUFACTURER'S WARRANTY. I EXPLAINED THAT MOST ALL OWNERS OF COBALT SS MODELS BETWEEN THE 2008 - 2010 MODEL YEARS WERE EXPERIENCING SIMILAR REAR BRAKE ISSUES, BUT WAS TOLD THAT DID NOT MATTER. THE PARTS WERE NOT COVERED UNDER WARRANTY, AND IF I WOULD LIKE THEM REPAIRED/REPLACED, I WOULD HAVE TO PAY FOR THE PARTS AND LABOR. *TR

PURCHASED CAR BRAND NEW, HAVE APPROX 10K MILES ON IT. REAR BRAKE CALIPERS SEEM TO NOT RELEASE FULLY- CAN BE HEARD GRINDING WHEN REVERSING AND SCREECHING WHEN GENTLY BRAKING WHILE MOVING FORWARD. REAR BRAKE PADS ARE WEARING UNEVENLY SO THAT THE OUTSIDE PAD IS SCORING THE ROTOR AND WEARING MUCH FASTER THAN THE INSIDE. POSSIBLE THAT THE SLIDER PINS ON THE CALIPER ARE NOT LUBRICATED? I'VE HAD MY LOCAL CHEVY DEALERSHIP WHERE I PURCHASED THE VEHICLE LOOK AT IT, THEY WROTE IT OFF AS BRAKES BEING A "WEAR&TEAR" ITEM. REAR BRAKES ONLY ACCOUNT FOR 20% OR LESS OF THE FULL BRAKING OF THE VEHICLE. WHY IS IT THAT MY FRONT BRAKES ARE FINE AND MY REARS ALMOST NEED TO BE REPLACED ALREADY? *TR

FRONT & REAR ROTORS SCORED SEVERELY WITH DEEP GROOVES THROUGHOUT. THE CAR HAS LESS THAN 12,000 MILES. BRAKING IS SEVERELY HINDERED DURING WET CONDITIONS AND PERIODICALLY THE BRAKES ARE NOISING MAKING "SCREECHING" SOUNDS AS THOUGH METAL TO METAL IS TOUCHING DURING BRAKING. PROBLEM IS MOST LIKELY DUE TO BRAKE PADS BEING FAR TO HARD OF A MATERIAL CAUSING EXCESSIVE WEAR ON THE ROTORS. *TR

I PURCHASED A NEW 2009 CHEVROLET COBALT SS SEDAN. THE CAR HAS BARELY BROKEN 10K MILES. THE BRAKES ARE WEARING ABNORMALLY FAST. I AM VERY GENTLE WITH THEM ALWAYS, AND THEY ARE VERY WORN ALREADY. PULLING UP TO STOP SIGNS OR TRAFFIC LIGHTS IS RIDICULOUS. THE SCREECHING FROM THE BRAKES IS LOUD. I HAVE NEVER HAD BRAKES GO OUT THIS EARLY ON ANY OF MY OTHER VEHICLES. *TR

HAD TO REPLACE REAR BRAKES ON 2009 COBALT SS AFTER ~ 12000 MILES. ROTORS HAD TO BE REPLACED. MADE VERY NOTICEABLE SCREECHING AND GRINDING SOUNDS. BRAKE PERFORMANCE HAD DECREASED VERY MUCH EVEN BEFORE THEY WERE REPLACED, DECREASE IN PERFORMANCE OF BRAKES AT ABOUT ~7000-8000 MILES. *TR
