The short answer is “yes.” It would not be easy for them to do so, nor would it be immediate or automatic; however, it is an eventual possibility. We would obviously keep up the good fight as long as we could, but ultimately they are in control of their system and customers should accept the fact that GM could eventually disable this. Of course, the question that always goes along with “can they,” is “will they,” which is really only a question GM can answer. We are all in agreement that it would be ridiculous for them to do so, as a happy GM customer is a loyal GM customer. There are far too many EVs both available now and coming on to the market that offer CarPlay/Android Auto. At the end of the day it’s their company and their choice, but you can’t argue with the data that shows customers very much want the option and will choose alternatives when those features aren’t available.
