NHTSA Complaint #10641576 — 2008 MERCEDES BENZ C350

I HAVE A 2008 C350 WITH 81,300 MILES. I DROVE THE CAR HOME FROM SCHOOL THURSDAY PARKED IT IN MY PARKING GARAGE WENT OUT THIS MORNING AND IT WOULDN'T START. THE KEY LOCKS AND UNLOCKS THE DOORS THE LIGHTS COME ON AND THE DASH LIGHTS UP. YOU CAN INSERT AND TURN THE KEY BUT THE CAR WILL NOT START. THE STEERING WHEEL IS LOCKED AND THE DRIVE IS LOCKED IN PARK. I TRIED JUMPING AND IT DID NOTHING I DIDN'T THINK THE BATTERY WAS BAD BUT WENT AND HAD IT CHECKED ANYWAYS. THE BATTERY BEING CHANGED. I CHECK THE FUSES THAT ARE ASSOCIATED WITH THE STARTER AND THEY SEEM TO BE OK. I'M NOT SURE WHAT TO DO NEXT AND NOT EXCITED ABOUT HAVING IT TOWED TO THE DEALERSHIP. ANY INFORMATION WOULD BE HELPFUL. *TR
