NHTSA Complaint #10201742 — 2006 CHEVROLET COBALT

I HAVE A 2006 CHEVY COBALT PURCHASED USED WITH 28000 MILES ON IT. ALL MY PROBLEMS STARTED ABOUT A MONTH AFTER I BOUGHT THE CAR. THE STEERING WHEEL STARTED SHAKING VIOLENTLY WHEN DRIVING AT 50 MPH AND OVER SO I TOOK IT IN TO A CHEVY DEALER AND THEY ROTATED AND BALANCED THE TIRES AND THAT SEEMED TO FIX THAT PROBLEM. ABOUT 2 WEEKS I WAS DRIVING HOME AND I WAS SITTING AT A RED LIGHT AND THE CAR JUST SHUT OFF. I RESTARTED THE CAR AND EVERY THING WAS FINE ON THE DASH BOARD, NO WARNING LIGHTS OR MESSAGES IN THE DRIVER INFORMATION CENTER. I STARTED DRIVING AGAIN AND WHEN I PRESS ON THE GAS THERE WAS THIS LOUD GRINDING NOISE AND IT FELT LIKE THE CAR WAS NOT SHIFTING GEARS PROPERLY. SO I PULLED OVER ON THE SIDE OF THE ROAD AND TURNED THE CAR OFF FOR ABOUT 10 MINUTES AND RESTARTED IT AND IT DROVE FINE. NOW AT THIS POINT IM JUST THINKING THAT THERE IS A MALFUNCTION IN THE COMPUTER. I TOOK THE CAR TO THE DEALER THE NEXT DAY AND THEY SCANNED THE COMPUTER AND FOUND NO ERRORS AND EVERYTHING WAS CHECKING OUT FINE. ABOUT 3 WEEKS LATER I WAS DRIVING ON THE HIGHWAY AND I LOST COMPLETE CONTROL OF STEERING AND THE POWER STEERING MESSAGE IN THE DRIVER INFORMATION CENTER WAS DISPLAYED ALONG WITH THE CHECK ENGINE LIGHT. UNABLE TO STEER I HAD TO STOP IN THE MIDDLE OF THE HIGHWAY AND SHUT THE CAR OFF. I WAITED ABOUT 20 MINUTES AND RESTARTED THE CAR AND THE POWER STEERING WARNING MESSAGE AND CHECK ENGINE LIGHT HAD GONE AWAY AND I GAINED STEERING CONTROL AGAIN. I ONCE AGAIN TOOK THE CAR TO THE DEALER AND THEY COULD NOT FIND ANYTHING WRONG WITH THE CAR. NOW SOME DAYS WHEN I START MY CAR THE POWER STEERING WARNING MESSAGE AND THE CHECK ENGINE LIGHT COME ON AND SOME DAYS THE CAR DRIVES FINE AND ITS REALLY STARTING TO FRUSTRATE ME. IN ADDITION TO THE STEERING PROBLEM I AM UNABLE TO REMOVE MY KEY FORM THE IGNITION. TO THIS DAY NONE OF MY PROBLEMS HAVE BEEN RESOLVED. *JB
