Difficult to give further advice than what has already been said and without further info from you.
As you say this has been a problem ever since you have had the camera I will make the assumption that you have read the manual, checked the settings and tried various 'modes'.
Set the camera to 'Manual', matrix metering, ISO 200, f11, and check that no exposure compensation has been set (+/- button top right). Go outside in good lighting (not direct sunlight). Using the cameras meter adjust the speed dial to achieve the meter needle in centre position (this will be somewhere around 1/125 to 1/250th.
Take three pictures, one with the meter needle centred, one with the needle to the right and one with the needle to the left.
Let us know the results.
Also, are these dark results happening with one specific lens ?
