Speedometer error - sticks at 50mph and will not drop

Funny you mention this old post. My 2009 370z started doing the same thing that ZForce had except.....when I reach 60 plus it says I'm going 180, below 60 is accurate. My tach was reading double as well but the car itself was running completely at normal. I have scoured the internet for someone else with the same problem as me, no luck until now. Not so happy about the issue but happy to see another that had the same issue.
We unhooked the battery for an hour to let the computer reset and it has fixed the tachometer but now the speedo says 140 in neutral HAHAHA, All I can do is laugh at this point because its so crazy. There has to be a reason this is happening and a solution to the problem..... replace the cluster....UGH, will be expansive out of warranty.
