2009 Chevrolet Cobalt SS Problems

I WAS DRIVING THE OTHER DAY AND NOTICED THAT ONE OF MY BACK BRAKES WAS STICKING AND SO I TOOK A LOOK AT IT AND FLUID LEVEL WAS FINE AND THERE WAS NO AIR IN THE BRAKE LINE. I FEEL THE CAUSE OF THIS IS BAD CALIPERS AND SOME OTHERS I HAVE TALKED HAD THE SAME ISSUE.

FUEL LINE RUSTS THROUGH CAUSING FUEL TO LEAK OUT NEXT TO EXHAUST PIPE. HAPPENS TO EVAP LINE AS WELL. POOR DESIGN IN THE HEAT SHIELDING TRAPS MOISTURE WHICH RUSTS THROUGH THE LINE. FUEL LEAKS OUT WHEN THE CAR IS RUNNING, PARKED, MOVING OR NOT. REAR BRAKE CALIPER STICKS OUT FROM USING THE PARKING BRAKE AND PAD STICKS TO ROTOR CAUSING EXCESSIVE WEAR.

MY AIRBAG LIGHT STARTED RANDOMLY GOING ON AND OFF. I NOTICED THAT IT OFTEN OCCURRED WHEN SOMEONE WAS SITTING IN THE PASSENGER SEAT. I ALSO NOTICED THAT WHEN SOMEONE WAS SITTING IN THE PASSENGER SEAT THE INDICATOR OFTEN INDICATED THAT NO ONE WAS SITTING THERE. THEN AFTER ABOUT A WEEK OF THIS OCCURRING, THE LIGHT AIRBAG REMAINED ON AT ALL TIMES AND THE INDICATOR STATED THAT NO ONE WAS SITTING IN THE PASSENGER SEAT EVEN WHEN SOMEONE WAS. I THEN TOOK MY VEHICLE TO THE DEALERSHIP AND THEY ADVISED THAT IT WAS THE PASSENGER AIRBAG PRESENCE SENSOR AND THAT IT NEEDED TO BE REPLACED. THEY ADVISED THAT IT WOULD COST OVER $1,000. SO OBVIOUSLY I TOLD THEM THAT I COULD NOT AFFORD IT AT THIS TIME. THIS IS A MAJOR SAFETY CONCERN AND SHOULD BE AN IMMEDIATE RECALL. I HAVE SEEN AND READ HUNDREDS OF COMPLAINTS ABOUT THIS EXACT SAME ISSUE ON TWO DIFFERENT COBALT FORUMS, THE NHTSA WEBSITE, AND ON VARIOUS OTHER WEB SITES THAT I ACCESSED THROUGH GOOGLE. IT IS OBVIOUSLY A MANUFACTURERS PROBLEM AND IT NEEDS TO BE CORRECTED BEFORE SOMEONE IS KILLED DUE TO THE NEGLIGENCE OF CHEVROLET. I AM OBVIOUSLY GOING TO GET THIS FIXED WHEN I GET THE MONEY EVEN WITH OUT A RECALL, BUT I THING THIS NEEDS TO BE INVESTIGATED AS SOON AS POSSIBLE AND I AM WILLING TO LET WHOM EVER USE/LOOK AT MY VEHICLE AS A STARTING POINT. NHTSA OR CHEVROLET PLEASE CONTACT ME SO WE CAN GET THIS PROCESS STARTED BEFORE SOMEONE GETS SERIOUSLY HURT OR KILLED. IM NOT SURE ON THE MILEAGE WHEN THIS PROBLEM ORIGINATED A FEW MONTHS AGO BUT, I BELIEVE IT WAS AROUND 80,000

MY AIRBAG LIGHT IS ON FOR MY PASSENGER SEAT. I HAVE TAKEN TO A DEALERSHIP AND THEY SAID THE SPECIFIC CODE IS NOT COVERED BY A RECALL. THEY SAID MY PASSENGER PRESENCE MODULE NEEDS REPLACED.

CONNECTOR FEEDING POWER TO THE A/C-HEATER BLOWER MELTED; CAUSED A CRACKLING SOUND, A SMELL, AND THE FAN TO STOP WORKING. THE CONNECTOR MELTED TOGETHER. TO GET A PICTURE OF THE PIN THAT FAILED REQUIRED ME TO BREAK THE CONNECTOR. POWER WAS PRESENT ON THE BROWN WIRE AS SOON AS THE IGNITION IS ON - THE BLOWER DID NOT NEED TO BE OPERATING TO GENERATE HEAT AT THE CONNECTOR. THE WIRE LEADING TO THE CONNECTOR WAS DISCOLORED FROM THE HEAT.

I STARTED MY CAR AND WENT TO TAKE OFF AND THE AIR BAG LIGHT CAME ON. THERE WAS A COUPLE OF INCIDENCES WHERE I HAD A PASSENGER AND THE AIRBAG LIGHT CAME ON TO SERVICE AIRBAG. I'VE READ IN MULTIPLE PLACES WHERE THIS OCCURRENCE HAS HAPPENED AND THE MANUFACTURE SHOULD FIX THIS.

FUEL LINE RUSTS THROUGH CAUSING FUEL TO LEAK OUT NEXT TO EXHAUST PIPE. HAPPENS TO EVAP LINE AS WELL. POOR DESIGN IN THE HEAT SHIELDING TRAPS MOISTURE WHICH RUSTS THROUGH THE LINE. FUEL LEAKS OUT WHEN THE CAR IS RUNNING, PARKED, MOVING OR NOT. REAR BRAKE CALIPER STICKS OUT FROM USING THE PARKING BRAKE AND PAD STICKS TO ROTOR CAUSING EXCESSIVE WEAR.

FUEL LINES UNDER THE CAR, DRIVER SIDE REAR STARTED LEAKING FUEL. THE LINES WERE RUSTED THROUGH AND FUEL LEAKED PAST THE EXHAUST SYSTEM WHERE A POTENTIAL CAR FIRE COULD HAVE HAPPENED IF NOT NOTICED RIGHT AWAY. THE VEHICLE WAS PARKED IN THE GARAGE AND OFF WHEN I NOTICED THE STRONG SCENT OF GAS AND SAW A SMALL PUDDLE OF FUEL UNDER THE CAR. REPAIRS WERE COMPLETED AT PORTER CHEVROLET SERVICE IN NEWARK, DELAWARE. REPAIRS CONSISTED OF REPLACING THE FEED LINE AND FILL LINE. THE ESTIMATE QUOTED WAS $800. REPAIRS ENDED UP COSTING $480.

WHEN I DRIVE THE AIR BAG WARNING GOES ON,AND THE TIRE STRESS GOES ON(WHICH MAKE ME SLOW DOWN WORRIED ! ). I REPLACED THE TIRES COUPLE OF TIMES BUT I STILL GET THOSE WARNING(TIRES STRESS AND AIR BAG). LATELY I ALSO RAN TO PROBLEM WITH MY ENGINE. I TOOK IT TO PEP BOYS WERE THEY SAID I SHOULD REPLACE IT FOR 5700$. *TR

I PURCHASED MY 2009 CHEVROLET COBALT SS SEDAN A LITTLE OVER A YEAR AGO. WITHIN THE FIRST SEVERAL MONTHS, THE EMERGENCY BRAKE STARTED TO GET EXTREMELY LOOSE. IT THAN COMPLETELY STOPPED HOLDING WITHIN 6 MONTHS AND 40,000 TOTAL MILES. AFTER THIS INCIDENT, THE REAR BRAKES AND ROTORS BEGAN TO PREMATURELY WEAR OUT EXTREMELY QUICKLY. SINCE THESE ARE NOT COVERED UNDER ANY WARRANTY AND DEALERSHIPS REFUSE TO FIX THE ISSUE FOR FREE, IT'S VERY COSTLY OUT OF POCKET FOR THE REPAIRS. I CAN'T PARK ANYWHERE NEAR ON OR A HILL, DUE TO THE EMERGENCY BRAKE BEING COMPLETELY BROKEN. AND THE REAR BRAKES AND ROTORS NEED EITHER REPAIRED OR RESURFACED CONSTANTLY EVERY SEVERAL THOUSAND MILES. MY OTHER MAJOR ISSUE IS WITH THE TPMS (TIRE PRESSURE MONITORING SYSTEM) THIS HAS BEEN GIVING ME AN ERROR CONSTANTLY FOR AROUND 10,000 MILES, ON HOW IT NEEDS TO BE SERVICED. MY CAR IS GARAGE KEPT WITH MAINTENANCE DONE ON TIME, AND WELL TAKEN CARE OF. *TR

DECEMBER 29, 2011, I WAS DRIVING HOME ONE EVENING IN THE COBALT WHEN MY CAR'S ENGINE SHUT OFF AND I LOST CONTROL ON A SEMI-RESIDENTIAL A FEW BLOCKS FROM HOME. DRIVING AT ABOUT 35-45 MP, DOWNHILL, I HIT A PARKED CAR ON THE LEFT SIDE OF THE ROAD (NARROW ROAD, CARS PARKED ON BOTH SIDES, 2-WAY STREET). I THOUGHT, "I'M GOING TO DIE". THIS IMPACT MADE THE CAR CONTINUE ON, FASTER AND MORE OUT OF CONTROL, HITTING ANOTHER PARKED VEHICLE ON THE OPPOSITE SIDE OF THE STREET AND I FINALLY WAS ABLE TO STOP THE CAR BY HITTING THE PASSENGER SIDE FRONT WHEEL/BUMPER OF THE COBALT AGAINST THE A PARKED TRUCK TO AVOID DRIVING INTO AN INTERSECTION OR ANY ONCOMING TRAFFIC. NO AIRBAGS EVER DEPLOYED. THE CAR THEN FLIPPED OVER, AND THAT'S HOW THEY FOUND AND RECOVERED ME. I AWOKE HOURS LATER IN SHOCK TRAUMA AT WASHINGTON HOSPITAL CENTER IN DC (WHERE I WORKED AT THE TIME), WITH THE CAR TOTALED AND JUST A SCRATCH ON MY HAND. I JUST HAD ACHES/PAINS, NO BROKEN BONES, BUT HAD TO TAKE SOME TIME OFF WORK. I HAD NO HEALTH INSURANCE AS I WAS A CONTRACTED EMPLOYEE. CAR INSURANCE PAID OFF THE EXPENSE OF VEHICLE. THANK GOD NOBODY WAS KILLED NOR SERIOUSLY INJURED. I HAVE ALL PAPERWORK, PHOTOS BUT I STILL DON'T DRIVE, MAYBE JUST ONCE A WEEK. THE YEAR OF THE COBALT IS FROM 2009, BUT I BELIEVE THIS VEHICLE SHOULD BE INCLUDED IN THE CLASS ACTION SUIT, AS IT WAS COMPLETELY UNSAFE TO DRIVE. *TR

VEHICLE'S AUTOMATIC DOOR LOCKS BEGAN TO ENGAGE AND DISENGAGE ON THEIR OWN, POSSIBLY LOCKING THE STEERING COLUMN AS VEHICLE ENTERED INTO A CURVE. CAUSED DRIVER TO LOOSE CONTROL GO INTO DITCH, BOUNCE OUT OF DITCH AND LOG ROLL THE VEHICLE. AIR BAGS DID NOT DEPLOY. DOOR LOCKS WERE STILL GOING UP AND DOWN SEVERAL HOURS LATER AT THE VEHICLE IMPOUND YARD AND WAS OBSERVED BY THE POLICE OFFICER AND NOTED IN HIS REPORT. ADDITIONAL. THIS PROBLEM IS MUCH BIGGER THAN BELIEVED! I HAVE A 2011 HHR AND HAVE HAD THE IGNITION SWITCH TURN OFF WHEN I HAVE DROPPED THE ADJUSTABLE STEERING COLUMN TO THE DOWN POSITION WHILE MOVING. I HAVE A HEAVY KEYRING AND WHEN I BROUGHT IT UP TO THE DEALERSHIP THEY TOLD ME THE KEYRING WAS THE PROBLEM. MY OTHER DAUGHTER'S 05 IMPALA HAD THE SAME PROBLEM WHEN SHE HIT A BUMP. *TR

WHEN I DRIVE THE AIR BAG WARNING GOES ON,AND THE TIRE STRESS GOES ON(WHICH MAKE ME SLOW DOWN WORRIED ! ). I REPLACED THE TIRES COUPLE OF TIMES BUT I STILL GET THOSE WARNING(TIRES STRESS AND AIR BAG). LATELY I ALSO RAN TO PROBLEM WITH MY ENGINE. I TOOK IT TO PEP BOYS WERE THEY SAID I SHOULD REPLACE IT FOR 5700$. *TR

CAR SUDDENLY SHOWED SYMPTOMS OF COOLANT LOSS A DYE AND PRESSURE TEST WAS COMPLETED AND FOUND NO EXTERNAL LEAKS. I DROVE THE CAR TO WORK THE NEXT DAY 15 MINUTE COMMUTE AND UPON ARRIVING LOW COOLANT INDICATOR POPPED UP I CHECKED THE DIP STICK TO CONFIRM MY FEAR THAT THE COOLANT WAS ENTERING MY OIL SYSTEM 1-WAY. HAD THE CAR TOWED TO THE DEALERSHIP AND AFTER 2 WEEKS OF TEARDOWN VERIFIED THE ENGINE HAD NOT SIGNS OF ABUSE AND THE HEAD AND HEADGASKET WAS NOT WARPED OR LEAKING/BLOWN. THE CAR WAS 2 MONTHS OUT OF WARRANTY AND GM DECLINED WARRANTY. LUCKILY I HAVE A 3RD PARTY WARRANTY AND THEY AGREED TO COMPLETE THE WORK DUE TO KNOWN ISSUES WITH SAID ENGINE/ SYMPTOMS . GM NOTIFIED ME THEY DID NOT HAVE A ENGINE AVAILABLE AND IT WOULD BE UNTIL OCTOBER BEFORE THE ENGINE WAS REPLACED AND DENIED TO OFFER RENTAL WHILE I WAITED AFTER A MONTH OF FIGHTING WITH GM CUSTOMER SERVICE THEY AGREED TO LEND A RENTAL CAR. TO THIS DAY MY CAR SITS IN A LOT ROTTING AWAY. A SHORT GOOGLE SEARCH OF CRACKED LNF ENGINES WILL BRING A HOST OF RESULTS EVEN MAJOR GM AFTERMARKET PERFORMANCE COMPANY'S ARE AWARE OF DEFECTIVE CASTINGS OF THE LNF ENGINE .. BELOW ARE A FEW EXAMPLES HTTP://WWW.COBALTSS.NET/FORUMS/DRIVETRAIN-79/CRACKED-BLOCK-2008-2-0-TURBO-62KMI-213316/ HTTP://WWW.COBALTSS.NET/FORUMS/PROBLEMS-SERVICE-MAINTENANCE-69/WHO-HAS-HAD-CRACKED-POROUS-BLOCK-LNF-287721/ *TR

MICHELIN PILOT SPORT A/S PLUS TIRES ARE "CHUNKING" AND HAVE DRY ROT/CRACKING ON THE TREAD. THE TIRES ARE 3 YEARS OLD WITH LESS THAN 20K MILES. THEY HAVE BEEN PROPERLY ROTATED EVERY 6K MILES. MICHELIN WILL NOT ACCEPT A WARRANTY CLAIM, AS THE TIRES WERE INSTALLED BY THE VEHICLE'S PREVIOUS OWNER.

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

SHIFTING I THREW THE GEARS QUICKLY TO GET UP TO SPEED OF TRAFFIC. THE SHIFT LINKAGE BREAKS AND CAR IS EITHER STUCK IN GEAR OR NEUTRAL WITH NO ACCELERATION CAUSING TRAFFIC TO BREAK HEAVY OR ACCIDENT BEHIND VEHICLE. REPLACE UNDER WARRANTY WITH SIMILAR PARTS BUT STILL SAME PLASTIC ENDS AND CLIPS SHOULD ME METAL ON DRIVE LINE PARTS. *TR

REAR BRAKES SEQUEL REALLY BAD AT TIMES AFTER DRIVING FOR A WHILE CAR HAS LESS THEN TWO THOUSAND MILES ALSO ON THE 20TH OF SEPTEMBER THE SHIFTER LINKAGE BROKE AND WAS NOT ABLE TO PUT CAR IN GEAR. *TR

I WAS TRYING TO START MY CAR AND TURNED THE KEY IN THE IGNITION AND MY CAR WAS COMPLETELY DEAD. I THOUGHT IT WAS THE BATTERY AND TRIED TO TAKE THE KEY OUT, BUT IT WAS STUCK AND WOULDN'T COME OUT. I GOOGLED HOW TO TAKE IT OUT AND THAT WORKED, WE JUMPED THE CAR THINKING IT WAS THE BATTERY, BUT WITHOUT THE KEY IN THE IGNITION, THE LIGHTS AND ELECTRICAL ALLTURNED ON. THIS TELLS ME THAT THE CAR'S IGNITOR/SHIFTER WAS STUCK IN THE "ON" POSITION. IT COULD HAVE BEEN A DANGEROUS SITUATION IF I WERE ANYWHERE BUT HOME. *TR

BRAKE PADS WEAR AT AN EXTRAORDINARY RATE. THEY HAVE ALSO GOUGED THE ROTORS. THIS IS ON A BRAND NEW 2009 CHEVY COBALT SS, LESS THAN 9000 MILES ON THE CAR (PURCHASED IN APRIL). THE BRAKES CONTINUALLY SQUEAK, AND HAVE DONE SO SINCE I PICKED UP THE CAR. THE DEALERSHIP EXPLAINED IT WAS A "BREAK-IN" PERIOD, BUT CLEARLY IT SHOULDN'T LAST THIS LONG. THE SQUEALING, IN ADDITION TO BEING ANNOYING, MAY POSE A SAFETY RISK DUE TO THE ACCELERATED PACE AT WHICH THEY BRAKE SYSTEM WEARS. I NOTICED AFTER A CAR/WHEEL WASH, THE NOISE DISSIPATES, BUT RETURNS SOON THEREAFTER. I'M CONCERNED ABOUT THE LONGEVITY OF THE BRAKE SYSTEM. *TR

THE PASSENGER SEAT BELT LIGHT STAY ON ALL THE TIME EVERY ONCE IN AWHILE IT MAY GO OFF BUT IT COMES BACK ON

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

REAR BRAKES HAVE BEEN DEVELOPING GROOVES BEING CUT INTO THE ROTORS. MAKES METAL SCRAPING/RUBBING/SCREECHING NOISE DURING BRAKING. *TR
