The foundation may just be setting and all, I wouldn't consider a major concern (as in I don't think your house is going to collapse in on itself or something to the like), but I also don't think that it would hurt to call someone or look into the matter a bit deeper. Damage to the basement is not good if too severe, considering it is not only the foundation to the house but is home to...well, everything that keeps the place running. Heater, boiler, water lines, gas lines, etc. Better safe than sorry, but like I said, I doubt it is anything serious. Houses, even new ones, get some superficial damage here and there, if only from the weight of them.
