Should clarify that dead pixel is different than hot pixel. Dead pixel is a defective pixel that is constantly bad. This pixel remains constant regardless of exposure time or ISO.

Hot pixels on the other hand is not absolute. These are pixels that appear brighter than adjacent pixels. As the exposure time is increase and at high ISO, the hot pixels becomes more apparent. Basically, the brightness difference gets larger between hot pixels and neighboring pixels. You can have hundreds of hot pixels if you go to extreme exposure times and ISO.

I believe dead pixels should be covered under warranty, but not hot pixels. But not sure, since I have not seen any explicit description of the coverage by camera makers.
