I just want to add my voice I too! I am dealing with the same problem ... I think Nissan should be more supportive with this problem... I am going to see it I can find out what is happening. With my vehicle no pattern is present but it first began more 3.5 yrs after purchase.
Good luck to all trying to find a solution......

I am having off and on buzzing/vibration within my instument gauge panel (2001 Nissan Altima). Is this what you experienced. Does anyone know how I can go about fixing it--it is driving me crazy.
