NHTSA Complaint #10238765 — 2007 BUICK LUCERNE

I PARKED MY 2007 LUCERNE FOR 17 DAYS WHILE ON VACATION. WHEN I RETURNED, THE BATTERY WAS DEAD. THERE WAS NOTHING PLUGGED INTO THE CAR LIKE A PHONE CHARGER OR ANYTHING ELSE. AFTER CHARGING THE BATTERY, I TOOK IT TO LOCAL DEALER WHO KEPT IT FOR OVER TWO WEEKS, PERFORMED A PARASITIC DRAW TEST, AND BASICALLY FOUND NOTHING EXCEPT A 201MA CURRENT DRAW OVER 7 DAYS. THE BATTERY AND CHARGING SYSTEMS CHECKED OK. THEY COULDN'T TELL ME WHEN OR FOR HOW LONG THAT 201MA DRAW LASTED OR WHAT CAUSED IT. THEY CLAIMED THAT SINCE THEY COULD NOT DUPLICATE THE PROBLEM, THEY CAN'T FIX IT SINCE IT'S "WITHIN SPECS" AT THIS TIME. I BROUGHT CAR HOME AND LET IT SIT UNTOUCHED/UNDRIVEN FOR 3 MORE WEEKS TO TRY TO DUPLICATE IT BEING PARKED ON MY VACATION, AND THERE WAS NO BATTERY DISCHARGE PROBLEM. HOWEVER, I FEEL I CAN'T TRUST THE CAR TO BE PARKED, UNUSED, FOR ANY LENGTH OF TIME (MORE THAN 2 WEEKS) FOR FEAR THE BATTERY WILL DISCHARGE AGAIN. *TR
