NHTSA Complaint #10156540 — 2005 CHEVROLET IMPALA

I HAVE A 2005 CHEVY IMPALA. ABOUT 2-3 TIMES WEEKLY, MY CAR WILL NOT START PROPERLY. I TURN THE KEY TO CRANK THE VEHICLE, AND IT TURNS OVER WITHOUT FIRING UP. SOMETIMES IT MAY DO THIS ONE TIME, AT OTHERS IT MAY DO IT 4-5 TIMES. IT IS VERY IRRITATING, AND SOUNDS HORRIBLE. I AM NOT SURE IF THIS IS DAMAGING TO MY VEHICLE IN ANY WAY OR NOT. I HAVE TAKEN IT TO THE DEALERSHIP ABOUT 3-4 TIMES SINCE I PURCHASED IT. THEY HAVE TOLD ME THAT THERE IS NOTHING WRONG WITH IT. THEY SAY THAT GM HAS INSTALLED A CHIP IN THE IGNITION THAT WILL CAUSE THIS TO HAPPEN. I DO NOT BELIEVE THAT IS TRUE, AND CANNOT GET A RESPONSE FROM GM. I HAVE SENT THEM EMAILS, AND HAVE GOTTEN REPLIES BUT NOTHING THAT HELPS. I WOULD APPRECIATE IT IF YOU COULD GIVE ME SOME HELP OF ANY KIND. PERHAPS YOU HAVE HEARD OF THIS PROBLEM ALREADY AND KNOW OF A SOLUTION. THANKS SO MUCH. *JB
