Hi guys. I recently started having some problems with my 2006 G35 coupe. The problem started after my OEM battery died which I replaced with an Exide battery, which I did myself. Here's a video. Note the random pattern(or lack of) of the clicks and the location of the clicking noise:





Situation: I open the garage door to park my car, the garage is dark. When I pull in, my lights are on auto and flick on for a couple seconds before I turn off the car. They stay on for about a minute after the car is off and that's when the problem starts(I think.) Car is off with no key in it. I found it late both times. Battery was too low to start both times so I jumped it, problem went away. About 4 days in between occurrences, so it doesn't happen every time.


What do you guys think this is?

 

That's a weird noise, but I don't have a clue what it might be.

 

Sounds like a relay. Check the fuse box in the engine compartment and also the IPDM near the passenger-side firewall.
