I bought mine in Jan.of 2016. Put a new battery in Jan of 2018. Was doing the same thing as yours when I needed a new battery. Like, all the dash lights came on and I couldn't get it to move. Thank God I was right across the street from Auto Zone so I just walked over and got a new battery. And with this issue I thought it might be the battery but I had the battery checked and it's good. So I'm hoping that changing the CPS fixed it! Good luck to you as well!
