cracked foundation?
I live in a new construction, built in 2006. today, I saw this in my backyard:

this is kind of scaring me. I touched the corner and the piece is kind of loose. Looks like I can probably pull that piece out.

1. is this bad?
2. is this something urgent that needs to be fixed?
3. how do I fix it? can I just patch it up with cement?

Is there any damage that you can see from the basement?

It looks as though there has been some water damage before. I get this from the sealant someone slathered on there. I would try binders to tie it back into itself. then skimcoat it with a good parging agent. This might serve as a temp fix only if it continues to pull away from itself.

I do not have a basement.

what are 'binders? btw, is this considered 'bad?" I mean, could this lead to serious foundation problems with the home?

If you have a crawl space look in there

If this is the only location that is cracked it will not cause the house to fall down, it is just and eyesore especially on a new house. If you can contact the original contractor, even though the 1 year warranty has passed, he should come over and repair it under warranty. It looks bad on the contractor and just a little bad word-of-mouth can be very damaging to him.
If he won't talk to you, you can break the cracked portion out, clean the space with a stiff brush and water, brush on an epoxy bonding agent, make some very stiff sackreet and apply it to rebuild the corner. Use a damp sponge trowel to rub it to the existing concrete. Keep it just damp and rub it in with the sponge several times at 1/2 hour intervals; this will keep it from drying out too quick and re-cracking.
