Query: Maybe it's defective?

I purchased this item for my 4 year old nephew's birthday. I tested it out to see how it works. I loved it and knew he would as well. It seemed to be the perfect blend of an educational toy and a "boy toy" (the drill is really cool) I was right- he LOVED it! He was able to use it almost entirely independently. It kept his interest for over a half hour. Then, suddenly, the "reverse" mode seemed jammed. He kept trying and after about three minutes, the drill started smoking. We haven't let him use it yet, for fear that it could be a very dangerous defect. I suppose we have to return it, but he keeps asking for his "machine" back and will surely be disappointed when he realizes he may never get it back. I am especially concerned since I bought two more of the same toy as Christmas gifts for other children in the family. Now I don't know whether to keep or return them! :-(
