Make sure you have the radio software update if there is one for your vehicle. My 2015 came with wifi capability but no way to buy it, until we had the dealer run an update. In my case, it was also the update that blocks hijacking of the system, which has since been updated for all models to the best of my knowledge. A simple update will likely get you right where you need to go! If you're kind to the dealer, they'll treat you well. It IS frustrating. Been there, done that, was without my Jeep 18 days while a new radio was ordered and installed, only to find that the later issues I had were again, software.
Get the updates, log what's wrong, when and what you should have, and it'll be fixed.
Some of us are waiting for updates to fix the "red light overhead" issue with 9-1-1 calls right now.
Good luck, and please keep us posted...shared information is the BEST information. Cars are no longer 4 wheels with entertainment, they're a computer that happens to go down the road.
