How do i fix my electrical problems?

Hello, no these are not "common issues" but they are issues that can happen with a vehicle that has this much age. Unfortunately, each concern will require troubleshooting. Back up camera - diagnostic testing is required to find out what's going on. Moonroof - The moonroof track should be checked for debris or restrictions. A physical inspection by someone who knows what they are dong is needed, as these tracks and cables are unique and require special attention. The brake lights - could be intermittently not working if the brake light switch or wiring connector is compromised. If one of the 3 lights, instead, is not working, it will require testing on it to see what's happening when the problem is occurring.
