Brightness Buttons issue, daylight sensor?

[DougChoe715]

Hello everyone, I have search and found few thread about brightness issues, so far the problem with the I recently pick up a new 2011 370Z 2 week ago.

I don't understand why during day light, I turn on "parking lamp" on, drl on and full on, the brightness button don't work while driving in full daylight outside and it only work at night? Am I missing something or it just malfunction need to be check out at the dealership?

Some one on this forum say it working fine for them when the vehicle is moving and brightness can be adjust but my car cannot, I find this odd and frustrating.

Thanks.
