Sometimes i'll go a couple of days where the doors may or may not unlock when i remove my key from the ignition. I'm pretty sure its the BCM. I have a 75k warranty so my real issue is getting someone at the dealership to see it in action, but after two visits I'm looking like a crazy person. Also I've heard a weird sound like a dying motor sometime when it happens. And the sound is coming from the locks. Is there a way for me to prove to these guys there is a problem other than it happening when they are in the car?
