I have a 2014 Kia and the bluetooth works well. I can control the spotify app using my volume/ffd/rwd controls on my steering wheel. The music plays automatically when I change the source from, let's say AM/FM to Media.
I've never tried to have it read my SMS. (Not sure how to even set that up).
I agree with Techitrucker. It's probably your car stereo and not the phone, although you may want to check to see if your bluetooth is set up to only broadcast phone calls or media as well. Check the stereo to see if it has that option in the bluetooth setup.
