So I just bought an 09 30z with 20 k on it.
I noticed one morning that when I started the car the speedometer did not do the initial cycle like it should. Then once I started driving the speedometer was off same with the Rpms. I was going 35 miles per hour and only read like 10. So took it to the dealer and after talking with Nissan techs they needed to replace it. They had to keep the car since they had to order a new guage cluster with same exact milage on it. They gave me a rental in the mean time

After new one got installed now the problem is the menu buttons on left side and dimming switches on the right don't work. Took it back and they were not able to figure out why.

So they ordered my old cluster back to swap. to see if its a problem with the new cluster they got or something else going on.

Any one got any ideas or had similar issues. I am really hoping they don't have to keep my car again.

Thanks
