Hey all. I have a '14 2SS/RS that I am having battery issues with. I bought the car in May and it is my 1st Camaro. The only electrical mods that I have done is added the Morimoto sequential taillights, an LED trunk light and a Phastek 3rd brake light. I drive the car at least once a week. The battery is dead after 3 days of sitting. I replaced the battery about 2 months ago.
I am not knowledgeable about electrical stuff at all. Just trying to find a place to start with figuring this out. Anyone else with similar mods have this issue? Thanks in advance!

Mine used to do that also. I had an update done to my blue tooth and fixed it. Ill see if I can find my old post. Drove me nuts.

I'd start with the tail lights.

If you messed with the tail lights like above i would check them but I found out this was my problem.
This was my post
This is the 3rd time in about 2 years I have had a dead battery. The first was shortly after I purchased it and installed a new battery. After the battery went dead the first time everything was great for about 6 months then dead after sitting all week. I charged and it was fine all summer. Last week dead. I was going to make a parasitic test cable to see whats going on.
I was at work and we have access to tech service bulletins so thought i would take a look. Guess what "16-NA-227 dead battery after exiting car following a blue tooth call. Some customers may complain about a dead battery after exiting car in 2-3 days". I was on the phone and just opened the door and it transferred to my phone and I walk away. I went to the car 4 days later dead.

Looks like onstar should be reprogrammed. It says some vehicles use the onstar module for the blue tooth.Going to take it in and give it a try. Just wanted to get it out there.
