THE CAR GOT VERY LOUD DRIVING HOME FROM WORK, GOT HOME SHUT OFF THE ENGINE AND IT WOULD NOT START AGAIN. HAD THE CAR TOWED TO HAVE IT LOOKED AT, THE MECHANIC REPORTED THAT THE TIMING CHAIN BROKE WHICH RUINED THE ENGINE.

THE VEHICLE STALLED AFTER I STOPPED THE CAR AT A STOPLIGHT (CITY STREET). BEFORE THAT (10 MINS OR SO) IT WAS LOOSING ITS ACCELERATION POWER AND THE ENGINE LIGHT CAME ON. I HAD IT TOWED AND THE REPAIR PLACE SAID IT WAS A MANUFACTURING DEFECT AND THAT I WOULD HAVE TO HAVE THE WHOLE ENGINE REPLACED. THERE WAS A FAULTY TIMING CHAIN COMPONENT.

LOW COMPRESSION IN ONE CYLINDER (74LBS) CAUSING INSPECTION FAILURE. FOUR IGNITION SPARK COILS FAILED AND CHANGED PREVIOUS TO ENGINE FAIL. LUCKILY THE ENGINE HAS NOT BLOWN OUT, NO ONE HURT. OTHER OWNERS HAVE THE SAME ISSUE. MY VEHICLE IS 9YRS OLD, UNDER 79,000 MILES, OIL AND FILTER (WHICH IS TERMED AS "SPECIAL"-IT'S A CORRUGATED "PAPER" FILTER AT AN ADDITIONAL $12+ EVERY CHANGE) CHANGED EVERY 3000 MILES. CATASTROPHIC ENGINE FAILURE IS NOT "NORMAL" FOR A VEHICLE OF THIS AGE WITH NO HISTORY OF OVERHEATING OR ANY OTHER ISSUE UP TO THIS POINT! HOPEFULLY NO ONE HAS BEEN OR WILL BE INJURED DUE TO ENGINE SEIZURE OR FAILURE WHILE DRIVING. JUST INFORMING OF POSSIBILITIES, THESE VEHICLES SHOULD NEVER HAVE BEEN SOLD! MY VEHICLE IS STATIONARY SINCE THE END OF APRIL UNTIL I CAN HAVE IT REPAIRED.

TL* THE CONTACT OWNS A 2007 CHEVROLET COBALT. WHILE DRIVING AT APPROXIMATELY 35 MPH, THE VEHICLE STALLED AND ALL THE WARNING LIGHTS ILLUMINATED ON THE INSTRUMENT PANEL. THE VEHICLE WAS ABLE TO RESTART. THE FAILURE RECURRED NUMEROUS TIMES. THE VEHICLE WAS TAKEN TO A DEALER WHERE THE CAUSE OF THE FAILURE WAS UNDETERMINED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 100,100.

AT ROUGHLY 110,000 ON A GENTLY USED 07 COBALT THE INTERNAL TIMING CHAIN BROKE AND RENDERED THE ENGINE USELESS. THE REPAIR - A TOTAL MOTOR SWAP FOR $5K! AFTER I RAN INTO THIS PROBLEM MY WIFE LOOKED UP OTHER REVIEWS ON THE COBALT AND FOUND OUT NUMEROUS PEOPLE HAVE HAD THIS PROBLEM. THIS IS A SUPPER EXPENSIVE ERROR THAT CHEVY HAS OVERLOOKED AND COSTLY FOR THE CONSUMER - US! AS WITH OTHERS, I WENT THROUGH ALL THE OFFICIAL RECALLS SUCH AS THE IGNITION AND POWER STEERING, AND THEN I PAID AN ADDITIONAL $600 FOR THE FUEL SYSTEM TO REPLACE - ANOTHER NOTORIOUS PROBLEM OF THE COBALT, AND NOW THIS!? COMPLETELY UNACCEPTABLE. IF YOU CANT MAKE A CAR OUT OF QUALITY PARTS, DON'T MAKE ONE AT ALL! ANYWAYS, LUCKILY THIS HAPPENED WHILE WE WERE PARKED BUT OF COURSE IT WAS VERY INCONVENIENT PLUS WE HAD TO PAY FOR THE TOW. IT MIGHT HAVE SHOWED SYMPTOMS OF A PROBLEM TWO WEEKS PRIOR WITH OCCASIONAL DIFFICULTY STARTING THE CAR WITH EITHER PROLONGED CRANKING, OR EVEN A SECOND TRY WAS NEEDED. I DON'T KNOW WHAT EXACTLY IS FAILING WHETHER IT'S THE PLASTIC PARTS OR THE TIMING CHAIN ITSELF, BUT THERE IS SOMETHING HERE THAT SHOULD BE INVESTIGATED AND ULTIMATELY LIFTED TO A RECALL CAUSE THERE ARE A LOT OF PEOPLE OUT THERE AFFECTED BY THIS, AND $5K ISN'T SOMETHING THAT ANYBODY SHOULD HAVE TO PAY FOR A CORPORATION'S INCOMPETENCE.

I WAS DRIVING DOWN THE ROAD, WHEN A WARNING SIGNAL WENT OFF ON MY CAR, A MESSAGE CAME UP THAT SAID "ENGINE POWER REDUCED" AND MY CARS ACCELERATION WAS SIGNIFICANTLY REDUCED. I COULD NOT GO OVER 10 MILES AN HOUR AND THE CAR WAS SHAKING VIOLENTLY. I PULLED INTO A GAS STATION THAT I WAS LUCKILY CLOSE TO, AND THE CAR LURCHED FORWARD AS SOON AS I PUT IT IN PARK, ALMOST CAUSING ME TO HIT THE BUILDING DIRECTLY IN FRONT OF MY PARKING SPOT. I TURNED THE CAR OFF AND LET IT SIT FOR MINUTE, ONLY TO TURN IT BACK ON AND HAVE IT ACT COMPLETELY NORMAL. I HAVE HAD 3 DIFFERENT MECHANICS LOOK AT IT, AND SEVERAL THINGS REPLACED AND THE PROBLEM STILL PERSISTS. MY CAR CANNOT GO MORE THAN 10 MINUTES WITHOUT HAVING THIS ISSUE, AND THE NEXT TIME IT HAPPENED I WAS ON THE FREEWAY AND IT ALMOST KILLED ME AND THE PERSON BEHIND ME. I HAVE READ THE CHEVY FORUMS AND COMPLAINS AND I AM NOT THE ONLY PERSON HAVING THIS ISSUE. THERE ARE MANY PEOPLE, IN MY POSITION WHO CANNOT AFFORD NEW CARS, WHO BOUGHT CHEVY'S BC OF THE AMERICAN NAME TO ONLY BE SCREWED BY THE CORPORATION. I HAVE NO CHOICE BUT TO DRIVE THE CAR AS I HAVE TO GET TO AND FROM WORK IN ORDER TO LIVE, WHILE THIS CONTINUES TO HAPPEN EVERY TIME I DRIVE THE CAR. SOMEONE. NEEDS TO MAKE CHEVY ACCOUNTABLE FOR THEIR TERRIBLE CARS!

CAR JUST TURNED OFF WITH NO POWER, WHILE BACKING FROM DRIVEWAY. COULD NOT STOP THE VEHICLE AND RAN OVER MY BOYFRIENDS FOOT. TWO NEIGHBORS WERE ABLE TO STOP MY VEHICLE SINCE WASN'T GOING FAST. NO WARNING. VEHICLE WOULD NOT RESTART. JUST PASSED ANNUAL INSPECTION AND ALWAYS FOLLOWED MAINTENANCE SCHEDULE. IT SHOULD BE NOTED THAT MY BOYFRIEND INJURED HIS FOOT AND WANTS TO FILE A CLAIM WITH MY INSURANCE.IM TRYING TO TALK HIM OUT OF IT BECAUSE I DON'T FEEL I WAS AT FAULT AND I DON'T WANT MY RATES TO INCREASE. CHEVY CORP SHOULD RESOLVE THIS ISSUE BEFORE SOMEONE DIES. I TOOK MY VEHICLE TO THE CHEVY DEALER AND THEY WANT TO REPLACE MY ENGINE AT MY COST. $3800. *TR

MY DAUGHTER WAS DRIVING HOME ON THE HIGHWAY DURING RUSH HOUR TRAFFIC WHEN THE TEMP LIGHT CAME ON SHOWING 240 DEGREES AND THE FAN KICKED ON AND THE LIGHT WENT OFF. THE TEMP LIGHT CAME BACK ON AT 304 DEGREES AND THE CAR DIED WHILE IN MOTION. WITHOUT SPENDING ALOT OF MONEY TO FIND SPECIFICS, THE MECHANIC IS UNSURE WHY THE COOLING SYSTEM FAILED CURRENTLY LOOKING AT THE POSSIBILITY OF HAVING TO REPLACE THE ENGINE IN ITS ENTIRETY. *TR

ITS BEEN ALMOST A MONTH SINCE MY COBALT WENT IN TO THE DEALER FOR IT TO GET FIXED. HARDLY ANYTHING HAS BEEN DONE FOR THE CAR TO BE REPAIRED. I HAVE CALLED TO CHECK AND ALL THEY SAY ITS THAT IS GOING TO BE READY SOON. MY DAUGHTER REALLY NEEDS THE CAR FOR SCHOOL AND WORK TRANSPORTATION. CAN SOMETHING BE DONE FROM THE GOVERNMENT SO THAT THE PROCESS CAN GO BY FASTER? IT WASN'T MY FAULT THAT THE CAR CAME OUT WITH ALOT OF PROBLEMS! *TR
