SERVICE BRAKES, HYDRAULIC
2009 CHEVY COBALT SUPER SPORT REAR BRAKES WEARING DOWN TOO QUICKLY. ONLY LASTED 10,000 MILES TO WHICH I WAS TOLD HAD TO BE REPLACED AT THE COST OF 470 DOLLARS. REMAINING FRONT BRAKES HAD MORE THAN 60 PERCENT OF LIFE. REAR BRAKES WERE COMPLETELY GONE. REAR BRAKE CALIPER FAILURE IS REASON, BUT CHEVROLET REFUSES TO ADMIT FAULT. *TR

TL*THE CONTACT OWNS A 2009 CHEVROLET COBALT. WHILE DRIVING THE CONTACT LOSS CONTROL OF THE STEERING WHEEL AND WAS FORCED SHUT THE ENGINE OFF SO THAT IT COULD RESET ITSELF. THE DEALER WAS UNABLE TO DIAGNOSE THE FAILURE. THE MANUFACTURER HAS NOT BEEN NOTIFIED. THE FAILURE MILEAGE WAS 650.

SERVICE BRAKES, HYDRAULIC
THE REAR BRAKES ON MY 2009 CHEVROLET COBALT SS ARE FAILING AT JUST 2400 MILES ON THE ODOMETER. THE INNER PADS HAVE WORN DOWN TOO QUICKLY, CAUSING EXCESSIVE GROOVING ON THE ROTORS. THIS HAS DECREASED BRAKES PERFORMANCE VASTLY. *TR

AIR BAGS
AIR BAGS DID NOT DEPLOY IN A 2009 CHEVROLET COBALT CRASH THAT CAUSED $7,200 IN DAMAGE AND ON STAR DID NOT CALL OR REPORT THE CRASH. WHEN I ASKED WHY, I WAS TOLD "BECAUSE THE "BRAINS" OF ONSTAR WAS "KNOCKED OUT" IN THE CRASH, THAT SHUT DOWN THE AIR BAG SYSTEM AND OTHER SAFETY MEASURES." FORTUNATELY, THIS CRASH DID NOT CAUSE ANY BODILY HARM TO THE PERSON INVOLVED, BUT THE WHOLE FRONT END OF THE CAR WAS PUSHED IN, RADIATOR WAS PUSHED BACK, WITH LOTS OF OTHER DAMAGE. THE PERSON IN THE CAR WAS FINE, BUT IF THE ENGINE WOULD HAVE BEEN PUSHED IN FURTHER IN, IT COULD HAVE BEEN IN THE LAP OR, EVEN WORSE, THE CHEST OF THE PERSON DRIVING. I DO NOT HAVE ON STAR FOR IT TO BE "DISABLED" IN A CRASH BECAUSE OF WHERE IT IS PLACED IN THE VEHICLE. THIS SERIOUSLY NEEDS TO BE EXAMINED AND FIXED BEFORE SOMEONE DOES REALLY GET HURT, IF THIS HAD NOT HAPPENED ALREADY. *TR

SERVICE BRAKES, HYDRAULIC
I DRIVE A 2009 COBALT SS. WHEN PUTTING THE CAR IN REVERSE AND BACKING UP I NOTICE A LOUD SCREECHY SOUND WHEN APPLYING THE BRAKES. I BROUGHT IT TO THE DEALER AND THEY SAID THIS WAS NORMAL. RECENTLY I LOOKED ON THREADS AND IT TURNS OUT LOTS OF OTHER PEOPLE ARE HAVING THE SAME PROBLEM. I ALSO SEE THAT THE BRAKES ARE WEARING OUT ALOT FASTER IN THE REAR. *TR

SERVICE BRAKES, HYDRAULIC, PARKING BRAKE
MY COBALT WAS PURCHASED 3/5/2009, AND HAS ONLY 5400 MILES ON IT AS OF 9/8/2009. I DO NOT DRIVE AGGRESSIVELY AND THE CAR IS PRETTY MUCH JUST DAILY DRIVEN TO WORK/HOME. THE REAR BRAKES ARE ALREADY EXHIBITING WHAT I'D CONSIDER TO BE ABNORMAL WEAR, ESPECIALLY WHEN COMPARED TO MY OTHER VEHICLES. THE ROTORS ARE BECOMING DEEPLY SCORED AND THE INSIDE BRAKE PADS ARE WORN MUCH MORE THAN THE OUTSIDE. HAVE BEEN TOLD ME THIS IS "NORMAL" (ALONG WITH A HOST OF OTHER ISSUES, INCLUDING OIL LEAKS FROM THE ENGINE). THERE ARE SEVERAL HUNDRED PEOPLE ON A NATIONAL COBALT FORUM ALSO EXPERIENCING THIS ISSUE. THE ROOT CAUSE APPEARS TO BE THE PARKING BRAKE NOT FULLY ALLOWING THE CALIPER TO RETRACT, BUT I'M NOT AN ENGINEER. *TR

SERVICE BRAKES, HYDRAULIC
REAR BRAKES ON MY 09 SS COBALT WERE GROOVED SO I HAD THE DEALER LOOK AT THEM, THEY SHAVED THEM DOWN AND DID NOT REPLACE THEM WHICH THEY SHOULD, THESE BRAKES CONSTANTLY GRIND AND SQUEAK EVEN THOUGH ITS A BRAND NEW CAR. MY BRAKES ON MY 2000 IMPALA ARE FINE BUT FOR SOME REASON THE BRAKES ON THE COBALT GRIND AND MAKE LOTS OF NOISE AND DON'T SEEM HEALTHY. *TR

SERVICE BRAKES, HYDRAULIC
I JUST BOUGHT MY CAR IN APRIL OF 2009. I OWN A 2009 CHEVROLET COBALT SS AND I AM SEEING A FAIRLY QUICK BRAKE WEAR RATING ON THE BACK BRAKES. UPON CLOSER EXAMINATION, I NOTICE THE BRAKES HAVE SOME PRETTY DEEP GROVES WHICH I HAVE NEVER SEEN BEFORE ON BRAKES DISCS ON A CAR. I RESEARCHED THESE GROOVES ONLINE AND APPARENTLY ITS CALLED "SCORCHING". ITS WHAT'S RESPONSIBLE FOR WEARING THE BRAKES AS QUICKLY AS THEY ARE. IT SEEMS TOO BE CAUSED BY FRAGMENTS OF METAL NOT FILED DOWN ON THE REAR CALIPERS ETCHING OUT THE REAR ROTORS. ITS ALSO BEEN BROUGHT TO MY ATTENTION THAT THE CALIPERS COMPRESS THE REAR ROTORS HARDER ON THE INSIDE OF THE ROTOR THAN THE OUTSIDE. THIS MIGHT BE ANOTHER REASON TO THE SCORCHING. *TR
