Reposition a small displaced brick wall
If you can get purchase on the wall with a rope and have a hitch on your car the poetic justice approach would be to attempt dragging it back into place. :-) But I expect this will just pull it off the carport pad and into your yard.

I suggest you contact a brickmason. From your description it sounds like there is a screened-in porch supported by that wall. You will need a mason to repair the wall or risk losing the porch. They might attempt to drag it in place and patch it but I doubt that. Most likely they demo the wall and build you a new one.
