2009 CHEVROLET COBALT SS Complaints

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

REAR BRAKE CALIPER PISTON DRAGGING CAUSING EXCESSIVE INNER PAD WEAR. REAR BRAKES FREEZE UP. DAMAGED REAR ROTORS. INADEQUATE BRAKE PEDAL OPERATION. *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

AFTER DRIVING ABOUT 4 MILES AND THEN BACK 4 MILES PARKED CAR. NOTICED GASOLINE DRIPPING IN THE DRIVEWAY. CALLED SERVICE GARAGE AND THEY SAID GET A TOW TRUCK,DANGEROUS TO EVEN TRY AND START CAR, ONE SPARK AND IT COULD EXPLODE. FOUND PROBLEM WITH FUEL TANK AND FUEL PUMP. HAD ONLY HAD CAR A FEW MONTHS. GARAGE REPLACED FUEL PUMP AND REPLACEMENT WAS DEFECTIVE ALSO. REPLACED IT AND PUT ON A NEW FUEL TANK. SEPT GOT A GM RECALL #12190 NOTICE. TO TAKE IT IN FOR FREE REPAIR TO A DEALER AROUND 40 MILES FROM MY HOUSE. HAD ALREADY PAID ALMOST $800 TO GARAGE WHEN I HAD THE CAR REPAIRED. NOW I HAVE A RECALL NOTICE 12045 BUT HAVE NOT BEEN ABLE TO FIND OUT WHAT IT IS FOR. CALLED RECOMMENDED GARAGE TO SEE IF THEY HAD PART TO REPAIR (CALLED TWICE NEVER HEARD BACK FROM THEM). STILL HAVE NOT BEEN ABLE TO FIND OUT WHAT THE PROBLEM. I ALSO FOUND OUT THAT THE ORIGINAL RECALL NOTICE ABOUT THE GAS PUMP HAD GONE OUT I BELIEVE A COUPLE OF YEARS EARLIER AND THIS WAS THE SECOND ROUND WITH THE SAME PROBLEM. GO TO A SITE ON LINE THERE IS ONE THAT COBALT DEALERS HAVE REPORTED THE PROBLEMS THEY HAVE HAD, THAT IS HOW I FOUND OUT ABOUT THE PRIOR RECALLI THINK THEY SHOULD HAVE TO TELL YOU WHAT IT IS THEY ARE RECALLING THE CAR FOR. IN THE FIRST GAS PROBLEM WE WERE LUCKY NOT TO HAVE HAD THE CAR EXPLODE. HAD I BEEN DRIVING ON THE INTERSTATE IT WOULD HAVE MADE A BIG NOISE. *TR

REAR BRAKES WEAR OUT VERY FAST FOR A NEW CAR, ALSO VERY NOISY AND DESTROY MY ROTORS. OUTTER PAD SEEMS FINE, INNER PAD IS DETERIORATING AT AN ALARMING RATE. *TR

THE REAR BRAKE CALIPER SEIZED AND CAUSED ME TO LOSE ALL REAR BRAKES. THE REAR BRAKE PADS WILL WEAR DOWN TO BARE METAL ON THE INSIDE SO NO WEAR BAR NOTIFIES THE DRIVER YOU HAVE AN ISSUE TILL YOU NO LONGER HAVE REAR BRAKES. THIS COULD CAUSE AN ACCIDENT! *TR

SHORTLY AFTER BUYING THIS CAR, THE PARKING BRAKE STOPPED WORKING COMPLETELY. THE REAR CALIPERS HAVE LOCKED UP AND DO NOT DO ANYTHING WHEN THE HANDLE IS PULLED UP. THIS IS A TERRIBLE DESIGN WHICH CAUSES, AT BEST AN INCONVENIENT, AND AT WORST, POSSIBLY DANGEROUS SITUATION AS, FOR A CAR EQUIPPED WITH A MANUAL TRANSMISSION, THERE IS NO PARK TO PUT THE CAR IN SO I HAVE TO BLOCK THE WHEELS WHEN PARKING UNTIL I CAN GET THIS PROBLEM FIXED. THE GM DEALER SAID THIS IS A COMMON PROBLEM BUT THERE IS NO PERMANENT FIX. HOW CAN SO MANY PEOPLE HAVE THIS PROBLEM BUT NOTHING IS BEING DONE ABOUT IT? WHAT IF I HAD PARKED ON A HILL AND MY CAR ROLLED DOWN INTO ANOTHER VEHICLE OR A PEDESTRIAN? *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

NOTICED PARKING BRAKE NOT HOLDING ANYMORE. THEN CHECKED REAR BRAKES AND FOUND REAR PASSENGER SIDE INNER BRAKE PAD (NOT THE OUTER PAD) COMPLETELY WORN OUT....ALL OTHER PADS ON CAR HAVE ATLEAST 70% PAD LEFT. NEVER SEEN ANYTHING LIKE THIS BEFORE WITH THIS LOW OF MILEAGE WITH NOT BEING DRIVEN IN ANY WINTERS. HOPE THERE IS A FIX FOR THIS! MAY BE PROPORTION VALVE DESIGN PROBLEM? *JS

BRAKE PADS AND ROTORS DID NOT LAST. MY BRAKES NEEDED REPLACING WAY EARLIER THAN THEY SHOULD. IT'S A SAFETY HAZARD. *JS
