I have had this problem probably since 6 months after purchasing the vehicle new. Nissan's response to the problem was that this kind of thing just happens, and offer to clean the battery terminals for about $50. At the time, I went and purchased battery terminal cleaner. Within the last few days I have had issues with extremely dim low beams and in the process of troubleshooting, I was told to take a look at corrosion on the battery terminals. I was blown away by the amount of corrosion on the positive terminal when I pulled off the terminal cap.
