Ongoing failure to start, multiple battery replacements in less than 2 years.

I HAVE HAD THIS VEHICLE FOR A LITTLE OVER A YEAR AND SINCE APRIL, I HAVE BEEN STRANDED IN DIFFERENT PLACES. THE REASON IS BECAUSE I WOULD GO TO GET IN MY CAR AND THE BATTERY WAS COMPLETELY DEAD. THE FIRST TIME THIS HAPPENED, THE DEALERSHIP SAID IT WAS A RECALL ISSUE THAT THEY CLAIMED TO FIX. THIS HAPPENED AGAIN 3 MONTHS LATER, AT NIGHT WITH MY BABY AT THE GROCERY STORE.
