My 2011 Prius had a blown head gasket so I went and replaced the engine with used one. You know how it goes. Anyway, after awhile when I'm slowing and coming to a stop, I get a hooting noise coming from under the hood. It quits by the time I open the door and get out. It's been happening for one to two weeks. Now today I get in and it won't start, dash doesn't come on. The door did open, but can't open the hatch, so I can't check the battery. I bought the Battery on 02/02/2020. Any ideas?
