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.

THE CAR SHUTS COMPLETELY OFF WHILE DRIVING, IT HAS ONLY HAPPENED AT LOW SPEEDS AND ACTS LIKE IT JUST STALLED. ONCE RESTARTED, THE CAR RUNS FINE. THIS HAPPENS AT RANDOM TIMES BOTH WHEN FIRST STARTING THE CAR AND ALSO AFTER DRIVING LONG PERIODS.

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!
