 I just bought a 2014 Nissan Altima 2.5 S,with only 40,000 miles at $14,000, I've had it going on maybe 3 months, now all the sudden in order for me to get it started I have to get a jump, had it tested everything came up good no problems, no codes and the battery is good.  Drive it home, turn it off ,push the button to start it, it makes a little sound , then nothing. Have to get another jump...I don't know what to do or who to do it with. Please can you help me
