After my 2013 ford focus sat in my garage for one month because we were on holidays, the battery was flat. I recharged the battery, then the car would start but nothing else electronically would work. I had to take it back to the dealer to get the system rebooted. Is this going to happen every time the car sits for a month? The dealer said to disconnect the battery when I go on holidays, but I can't shut the hood and lock the car then as I can't get back in. What do you think?
