Didn't start my 2008 Ford Escape Hybrid for about 2 weeks and wouldn't start

Hi all! I have been working from home the last 10months and don't drive my 2008 Escape hybrid as often. I have been starting it and driving it at least every week but didn't do that for two weeks and when I went to start it the stop safely caution thing popped up. Anyone knows what I should do? The hybrid battery was refreshed 2 years ago and functions good but I asked my uncle (he has 3 of these in SF) and he said there's a small part to replace thats about $150.00 that usually comes up when you don't start it for a little while. All help is appreciated. Picture included (from internet but exact same as mine) Also anyone in the DMV area that knows a mechanic for my vehicle....
