Google pixel xl3 will not auto connect to bluetooth

[Android Central Question]

Let me explain. I will receive (or make) a call. My phone is connected in Bluetooth mode bc my Spotify works from my phone. Call comes inand I hit 'accept' the call goes to speaker on phone automatically. I have to click Privacy button twice to get call on vehicle Making a call the 'end call' lit up. Other options not. I have to click Privacy button twice to get it to connect also. And on phone face the Bluetooth button is lit up, activated. I go to settings on my phone and it's connected only to vehicle.
I did a factory reset couple weeks ago bc I have an app that's announces callers name and it would randomly choose a name from my contacts to announce. App is called 'Shouter'
Help please
