Battery Dead problems of the 2011 Nissan Juke

In August of 2013 I purchased a 2011 Nissan Juke. 2 months later the battery died. I replaced it. Between that time and March 2015 I had to replace the battery 2 addition times. In March of 2015 again the battery dies. I jumped started it a couple of times in a period of 3 days. On the 4th day while driving the car acted as if it would stall on me while driving. This scared me enough to take it into the dealership. They ran diagnostic test on the car and found nothing. They replaced the battery (corporate reimbursed me for the cost) now in Feb 2016 the new battery they installed died again. I did as they advised me to do the previous time which is to have it towed into the dealership instead of jump starting it and driving it to them. Again they ran diagnostic test and found nothing. They have again replaced the battery. The dealership acts as if the problem is fixed. My concern is that a few months from now the car will again drain the battery. What about if it drops a charge while I am driving it on the road? I have read several complaints on line regarding the same issue with other 2011 Juke models but I do not see it mentioned on the national highway safety administration website.
