If somehow you turned your camera off after choosing high ISO noise reduction "off", the setting automatically returns to "standard".

It is normal to see hot pixels on long exposures. If that is when you see them, then the camera is fine. There is a reason that the long exposure noise reduction option exists.

Its also normal to see hot pixels on fast high iso exposures too.

You say..."If somehow you turned your camera off after choosing high ISO noise reduction "off", the setting automatically returns to "standard".

If your camera does that, send it in to be repaired.
