One day this week I stopped at the ATM and when I got back in my car( about 4 minutes later) it would not start. There was no power at all, no cranking, no clicking, no lights, totally dead car. After about 45 minutes I finally got someone to give me a jump and it started right away. Now for some of the particulars; it’s a 2009 v6 with Premium pkg. It has184k miles and the battery was replaced last summer. I haven’t had any issues at all with the car. It has always started right up even in the coldest of times. The weather on this particular day was sunny and in the 60’s. I took the car to my friends shop and we put the tester on it and all components were charging and working as should be with a full load on the system . Has anyone here had this or a similar experience? Or does anyone have any idea on what might be the issue?
