This is a long shot, but maybe someone else has had the same problem and knows how to fix it.
I own a 2014 TC Platinum, and the rear lift gate is malfunctioning. It started out by not allowing me to open the rear lift door when when the button was pressed on the door, and it would only do this intermittently. Now the problem has progressed and it is now triggering an open for the rear door all on its own at random times.
I have already tried replacing the Rear Lift Gate locking module (cheap and easy to change). The dealer thinks the only other option is to replace the BCM (body control Module) but they are not positive that it will fix the problem. As this is rather expensive, and it looks like it has to be done by a dealer because it will have to be reprogrammed, I am looking for other options or ideas.
Thanks.
