Sounds like a loose or bad ground/power cable. Being a 2012, there have been quite a few people with weak batteries that have needed replacement, I replaced my battery in my 2012 over 2 years ago. If you live in a very hot environment batteries can easily need replacement every couple of years, I replace mine every 4-5 years before I ever experience any problems that could leave me stranded.
