I got kind of the same problem just happened yesterday, when I pull the latch, it has that "hood already popped" feeling, like there's no tension on it, but the hood won't pop. I even tried prying the hood up, I could get it up far enough to get my fingers under it but as hard as I pulled it wouldn't come up. This is really annoying, all I wanted to do was just look around the engine bay make sure everything loooked alright.
