Cracks in concrete patio

Cracks in concrete patio
Our house is about a year old. The patio is 15 x 34 - about half of it is covered. I realize that it is normal for large areas to have some cracks but we have about 4 that run from the house all the way to the edge of the patio (15 feet). A couple of these appear to be shifting as settling occurs because the patio of one side of the crack is slightly higher than one the other side. I have also noticed within the last couple of days that new cracks are forming and that there are some now that run partially across the length of the patio. Since I have never had a pation like this before, I don't know if this is normal. I certainly hope not as it looks like it will all be stepping stones before long. If it isn't normal, I have to do something soon because my 1 year builder's warranty runs out in 1 month.

I might expect a crack along an expansion joint, but wholesale cracking and settling such as you describe seems to indicate that the base for the patio is inadequate. I would invoke the warranty before it expires.
Proper preparation and installation should have prevented all cracking except for along expansion joints.
I suspect that removing the pad and rebuilding it from the base up will be needed to remedy this situation.
Hope this helps.
