MY DAUGHTER IS DRIVING A CAR WITH A FUEL LEAK THAT IS HAS A RECALL IN SOME STATES FOR THE PROBLEM BUT NOT IN MINE. RECALL # 090226 , HOW IS THAT POSSIBLE, PLEASE HELP! I THINK I HAVE TO WORK AS HARD FOR MY MONEY AS OTHER STATES, AND I AM CERTAIN MY CAR COST AS MUCH TO PURCHASE AS IN OTHER STATES. HER CAR HAS FUEL DRIPPING BETWEEN THE DRIVERS DOOR AND LEFT REAR WHEEL. APPEARS TO BE STARTING AROUND TOP OF TANK LOCATION.

THE CAR LIGHTS WILL FLICKER ON AND OFF WHILE DRIVING. STRONG SMELL OF GAS AFTER I PUT THE CAR IN PARK. BEEN GOING ON FOR THE FLICKERING 2 MONTHS NOW. FOR THE FUEL 2 WEEKS NOW

I HAVE RECENTLY HAD MY COBALT TO THE CHEVY DEALERSHIP IN REDLANDS CA DUE TO A HORRIBLE GAS SMELL. THE DEALERSHIP LOOKED IF MY CAR WAS UNDER RECALL FOR THE FUEL PUMP HOWEVER IT WAS NOT. I INDEED HAD A CRACK ON THE FUEL PUMP HAVING TO REPLACE IT AS THE FUEL SMELL WAS OVER THE TOP. I PAID FOR THE PART AND LABOR OUT OF POCKET YET WONDER WHY MY VIN WAS NOT RECALLED WHEN I HAVE A 2009 CHEVY COBALT WITH THE EXACT SAME FUEL PUMP ISSUE???

I HAVE A 2009 CHEVY COBALT AND SINCE I PURCHASED IT IT HAS BEEN PROBLEM AFTER PROBLEM FIRST THE KEY GOT STUCK IN THE IGNITION BEFORE THE RECALL. I HAD TO SPEND ALL DAY AT THE DEALERSHIP, THEN I HAD TO TAKE IT BACK FOR THE IGNITION SWITCH RECALL. NEXT IT WAS TAKEN BACK FOR SUSPENSION PROBLEMS AND A CRACKED STEERING COLUMN, NOW I KEPT HEARING A NOISE WHEN I PRESSED THE GAS TO SPEED UP TOOK IT TO TWO PLACES AND IT WAS THE CATALYTIC CONVERTER WHICH COST ME $1,548 OUT OF POCKET BECAUSE THE WARRANTY I HAD DIDN'T COVER THE CATALYTIC CONVERTER THIS CAR ONLY HAS 89414 MILES ON IT I KEEP UP THE MAINTENANCE BUT THIS CAR IS BEGINNING TO MAKE ME NOT WANT TO BUY ANY AMERICAN CAR EVER. I INITIALLY PURCHASED THE CAR BECAUSE IT WAS ECONOMY CAR,GOOD ON GAS WHICH IS STILL GOOD ON GAS. I SEEN IN THE EARLIER MODELS THERE WERE RECALLS ON THE CATALYTIC CONVERTER SO I WAS TRYING TO FIND OUT IF THERE WERE ANY ON THIS PARTICULAR MODEL? WHEN I PURCHASED THIS CAR I WAS HAPPY ABOUT THE THE CAR BUT PROBLEM AFTER PROBLEM IS BEGINNING TO BE MORE THAN I CAN HANDLE AND THE LAST THING IS THIS CATALYTIC CONVERTER, THANK GOD I HAD THE MONEY. THE CATALYTIC CONVERTER WAS CRACKED AND GASKETS HAD TO BE REPLACED.

SERVICE ENGINE LIGHT HAS BEEN ON INTERMITTENTLY FOR A YEAR. DEALER SAID IT WAS PROBABLY DUE TO A LOOSE GAS CAP AND NOTHING MORE. ENGINE STARTED SHAKING WHEN STOPPED AT STOP LIGHTS AND THE SERVICE TRACTION AND TRACTION OFF LIGHTS WOULD COME ON. THE ENGINE LIGHT WOULD START BLINKING, AND IF THE CAR WAS STOPPED FOR TOO LONG THE ENGINE WOULD SHUT OFF. ONE MECHANIC SAID IT WAS THE CAM SHAFT, WHICH I GOT FIXED AND STILL CONTINUED TO HAVE THE SAME PROBLEM. TOOK IT TO ANOTHER MECHANIC WHO REPLACED THE CYLINDERS. PROBLEM CONTINUES TO OCCUR WHICH ENGINE SHUTTING OFF IF STOPPED LONGER THAN A MINUTE. *TR

TL* THE CONTACT OWNS A 2009 CHEVROLET COBALT. THE CONTACT STATED THAT WHILE DRIVING AT 50 MPH, ENGINE POWER REDUCED THEN THE VEHICLE STALLED. THE VEHICLE WAS TAKEN TO A INDEPENDENT MECHANIC WHERE THE MECHANIC WAS UNABLE TO DIAGNOSE THE FAILURE. THE MANUFACTURER WAS CONTACTED ABOUT THE FAILURE. THE FAILURE MILEAGE WAS 90,000 AND THE CURRENT MILEAGE WAS 94,000.

TAKATA RECALL, I WAS DRIVING MY VEHICLE 2 WEEKS AFTER 2 RECALLS WERE REPAIRED ON IT. IT WAS RUSH HOUR I WENT TO PUSH ON MY BREAKS AND THE STEERING WHEEL LOCKED AND THE CAR TURNED OFF, AT THIS POINT IM FREAKING OUT. I CONTACT CHEVY SERVICE FOR ASSISTANCE AND THEY ADVISE THAT THEY CAN NOT FIX THE PROBLEM BECAUSE THE RECALL WAS REPAIRED THEY ALSO COULD NOT DUPLICATE THE PROBLEM BECAUSE IT WAS TO DANGEROUS FOR THEIR EMPLOYEES. SO I ASK THE BANK TO REFINANCE ME ANOTHER VEHICLE BECAUSE THIS CAR WAS WAY TOO DANGEROUS TO PUT MY BABY IN, THEY SAID NO DUE TO MY CREDIT. I THEN HAD THEM REPO THE VEHICLE BECAUSE I WOULD NOT CONTINUE TO PAY FOR A DEATH TRAP. NOW THEY ARE SUING ME FOR THE REMANDING BALANCE ON THE VEHICLE. I AM GOING TO COURT AND WONDERING IF I HAVE A CASE.

I DROVE MY CAR AROUND 7:15 AM UNTIL ABOUT 10:00 AM. EVERYTHING WAS FINE. WHEN I STARTED IT UP AGAIN I HEARD THIS LOUD NOISE COMING FROM THE ENGINE. IT SOUNDED LIKE A DIESEL TRUCK. MY FLEX PIPE WAS DISCONNECTED. THIS ATTACHED TO THE MANIFOLD. I DIDN'T HIT ANYTHING TO CAUSE THIS PROBLEM. I ASKED THE REPAIR MAN WHAT COULD HAVE CAUSED IT AND HE DIDN'T HAVE AN ANSWER.

THE KEY WILL NOT TURN IN THE IGNITION CYLINDER. THEREFORE THE CAR WILL NOT TURN OFF. THERE IS A SPECIAL BULLETIN #10256 ABOUT THIS EXACT PROBLEM INCLUDING ONLY THE 2009 COBALT HOWEVER AS THERE IS NOT AN OPEN RECALL THE MANUFACTURER WILL NOT REPAIR MY CAR BECAUSE MY CAR HAS A BRANDED TITLE AND THEY WILL ONLY REPAIR 'OPEN RECALL' ITEMS. THIS ISSUE IS NOT LISTED IN THE GLOBAL DATABASE WHEN MY VIN IS SEARCHED BUT IT NEEDS TO BE LISTED UNDER MY VIN AND THERE NEEDS TO BE AN OPEN RECALL ON THIS ISSUE BECAUSE IT IS CERTAINLY A HUGE SAFETY PROBLEM THAT MANY OWNERS HAVE BEEN EXPERIENCING. THE ONLY WAY TO TURN THE CAR OFF IS TO GET UNDER THE HOOD AND REMOVE THE FUEL RELAY FUSE. IN CASE OF A FIRE THIS WOULD BE A CATASTROPHIC SAFETY ISSUE WHICH COULD RESULT IN SERIOUS INJURY OR EVEN DEATH. *TR
