I bought my 2005 G35 Coupe 5AT around 3 2.5 months ago and I have noticed some interesting issues. First, if the outside temperature is above 70-75 degrees Fahrenheit the navigation screen will pop up and then immediately go back down if I try to access it. Second, my drivers side door lock actuator will not work at temperatures above 80 degrees Fahrenheit. I know that these are common problems with G's on their own, but mine are specifically caused by the heat. Has anyone experienced something similar?

 

Electrical motors act very odd in their late life. It all depends.
