Trying to find horror movie

Howdy

So I only remember bits and pieces from the trailer and I don’t even remember where I found that.

I think it’s around the 2000s or 2010s and I also think it’s entirely available on YouTube

What i do remember

1. Weird child / girl standing on balcony back the camera
2. A guy in a truck(?) asks a girl outside if she’s alright and then boom she slams into the side of the truck rapidly or something similar to that
3. They have like an uncanny smile or face just its just weird

That is literally all I remember and my google searches are turning up nothing
