NHTSA Complaint #10214007 — 2008 GMC ACADIA

MY COMPLAINT CONCERNS MY 2008 ACADIA DELIVERED SEPT.2007. CURRENTLY WITH LESS THAN 5,900 MILES ON IT. IT IS NOW IN THE SHOP FOR FAILURE TO START FOR THE THIRD TIME. THE BATTERY IS SOMEHOW BEING DISCHANGED. OTHER THAN REPLACING THE ORIGINAL BATTERY, ON THE FIRST OCCURANCE, THE DEALER SERVICE CAN NOT SEEM TO TRACK DOWN THE SOURCE OF THE PROBLEM. THEY SAY THAT THE CHARGING SYSTEM CHECKS OUT OK. IT DOES SEEM TO START FINE FOR A WHILE, SEVERAL WEEKS, THEN ALL OF A SUDDEN IT WILL HAVE A DEAD BATTERY OVER NIGHT. NOTHING IS EVER LEFT ON. I CHECK THAT EACH TIME THE GARAGE DOOR IS CLOSED. THE HEADLIGHTS ALWAYS GO OUT IN ONE MINUTE, IF ON. WHILE DRIVING I DO NOTICE THE VOLTMETER ON NUMEROUS OCCASSIONS WELL STAY AT ABOUT +15 VOLT CHARGING RATE. I KNOW THAT IT SHOULD BE NO HIGHER THAN ABOUT +13.5 VOLTS, AND SOMETIMES IT DOES, BUT MOST TIMES, NOT. I AM CONCERNED ABOUT A POSSIBLE FIRE DANGER AND BEING STRANDED SOMWHERE. I AM AN AIRCRAFT A&P. MY TROUBLE SHOOTING THOUGHTS POINT TO A STARTER SHORTING. I COULD BE WRONG BUT I WOULD START THERE AND PROVE THAT NOT TO BE THE PROBLEM. EASIEST FIX FIRST, THE AIR FORCE WAY. *TR
