I have an appointment to install PPF on mine in September. Hope my installer knows about this potential issue and how to fix it.....
Rather than leaving the doors open (I checked my app when they were installing it, and after a day's worth of work they always closed all doors, hood, and trunk), the issue may be that they leave the key inside and do not lock the car, leaving the system running. I would suggest to your installer that they close all doors, hood, and trunk, and take the key out of the vehicle and lock it. This may not be possible depending on what they were working on when closing the shop.
