My 2009 G37x has been having this issue with the back up camera in hot weather, it's perfectly fine in cool weather. Has anyone seen this before? Or can you tell me how to access the wiring in the trunk area so i can look for issues/corrosion?

 

I've never seen that issue before.. have you pulled the interior trunk lid lining to make sure the camera is properly connected?

 

I have not, I was unsure of how to safely pull the lining without damaging it/not being able to reattach. How does one remove it?
