So, I have been using the cadillac app just like the volt's to open/lock/pre condition the car when low and behold it said I have to upgrade to the $15/mo subscription. I imagine there was a free trial period when I obtained the car. I think they tried the same crap with the chevy app but changed it later. So there is no other way to use the app w/o paying 15/mo. Any other options that anyone knows? Complaining to corporate?
