Any help on this before I just tear the damn thing apart? When it decides to "go rogue", all you can hear is the trunk clicking open almost non stop.

 

Not any good ones. If it were mine I would spray a little WD 40 on it. But only if it looks "sticky stuck". If it looks like it's just jammed in too far you will probably need to remove the whole thing. Perhaps the spring has jumped off its guide. I was just going to suggest just pull the harness off to prevent the power to the switch but then you can't get in. So never mind on that.

 

I think that it's the little black button next to the backup camera that's stuck. It's pushed in and just can't release.
If I pull the power off the harness to the little black button, I wonder if the FOB trunk opener will still work???

 

What year charger do you have?

The button is not stuck, but actually broken. It is a known issue. Happened on my car as well.

You can buy the new part on ebay for $16.

Install from start to finish takes about 20 minutes. Very easy. Open the trunk, remove a few plastic push clips holding the trunk liner in, pull down the trunk liner enough to get at the 3rd brake light, I think there might be some screws not 100% sure, remove the old button, disconnect the wire connection, put the new one in, put it all back together.

It will then work good as new.

 

I've got an '11.

I just found a TSB on this. Apparently the plastic button on some years was prone to leaking and let water in to short out the circuit. The TSB is to replace the plastic button with a rubber one to get a better seal. Parts and labor at the dealership is $65. Got an appointment to take it in this week.
