NHTSA Complaint #10617266 — 2010 CHEVROLET COBALT

THE CHECK ENGINE LIGHT HAS BEEN ON CONTINUOUSLY FOR THE PAST YEAR. MULTIPLE DIAGNOSTIC TEST HAVE POINTED TO A COIL PACK OR SPARK PLUG MISFIRE PROMPTING A REPLACEMENT. EACH TIME THE COIL PACK OR SPARK PLUGS ARE REPLACED, THE CHECK ENGINE LIGHT GOES OFF AND WITHIN THE SPAN OF A FEW HOURS OR THE NEXT DAY THE LIGHT COMES BACK ON AGAIN. I TAKE THE VEHICLE BACK IN FOR ANOTHER DIAGNOSTIC AND THE SAME CODE POPS UP AGAIN. THERE IS A CONTINUOUS MISFIRE WHICH CAUSE THE CAR TO LOOSE THE ABILITY TO ACCELERATE OR CAUSE THE VEHICLE TO SHAKE VIOLENTLY WHILE DRIVING. THE A/C INCREASES THE CHANCES OF THESE OCCURRENCES. AT THE LAST CHECK THE MECHANIC FINALLY TOLD ME THAT THERE MUST BE AN ELECTRICAL PROBLEM BECAUSE HE KEEPS GETTING THE SAME CODE AND THEY HAVE REPLACED IT TOO MANY TIMES FOR IT TO STILL BE THE SAME PROBLEM. IT WAS SUGGESTED TO ME THAT THIS PROBLEM MAY BE A MANUFACTURE DEFECT. I LOOKED INTO IT AND HAVE FOUND SIMILAR COMPLAINTS FROM OTHER COBALT OWNERS. *JS
