I'd return it for sure.
But just to make sure we're all talking about the same thing... Is this hot pixels on the sensor, that you can see when reviewing on the LCD, or is this pixels on the LCD that are stuck on?
On an LCD of that size, there is no excuse for a stuck on pixel. Stuck on is significantly more distracting than stuck off, and it is obviously defective.
On a sensor, there will always be a few hot pixels, and will usually get worse as sensor temp increases (video, long exposure, live view). You just have to determine if the number present on your sensor are acceptable to you. If you are asking the question, then it probably isn't.
Like I said at the top, return it.
