Treated Lumber Porch Steps

Last June I used treated 2 x 12 s as treads to build steps for my front porch. Yesterday I noticed they have begun to crack and curl to the point that they are pulling up from the stringer, even though I used 3" deck screws. Any suggestions as to why, and what I might do about it? Any help appreciated.

You used the wrong sized lumber. You should never use anything wider than 8" on outdoor decks or steps. In this case you should have used 2 - 6" treads insteat of 1 - 12". You may be able to remove the treads, cut them in half and rescrew them to the stringer. If they are too curled to do this replace then with 1"X6" or 2X6".
