I have a 2004 Altima, and yesterday when I tried to start my car after gonig to the grocery store, it would not start. It was working fine before I got there. No headlights or interior lights were left on, but when I tried to start it, it did nothing. Thought maybe I had a dead battery, but my headlights and interior light worked fine. My BF suggested maybe I had hit the panic button and somehow disengaged the car fron starting? I hit the door open and close on my key fob a few times, and in a short time, it finally started, but my radio and clock were all out of whack and needed to be reset. It was like it had a computer malfunction. Anyone have a clue what this could be from? and do you think I should take it to my dealer and have it looked at? Thanks!
