If anyone could help me with this issue that would be much appreciated. Keep getting this error message and/or this screen randomly while car is either running or upon start up. It's not a overheating issue as it happened this morning after being garaged all night. When the fuzzy screen occurs, all dash controls like the AC buttons become unresponsive. Have not taken the car to Infiniti yet, would rather see if this is a common problem that can be fixed before I lose an arm and a leg to the dealership. Please feel free to comment, any advice is welcome.

 

I'm having somewhat the same problem. When I start my 08 g37s coupe the radio won't come on and i cant control my a/c if comes on from time to time but once I turn car off when the radio do works it wont come back on.
