2011 Sonata-Phone stays connected when car is off
 

Hello everyone. I did a search on this topic and didn't find anything... I have a 2011 Sonata with Nav and bluetooth. The bluetooth connects great. However, when I get into to the car while on a call (key in my pocket) the phone connects to the car bluetooth even when the car is completely off... I can't hear the call through the car audio because it's turned off. I can't hear the call on the phone because it's shows it's connected to the Sonata. I have to manually select the source on my phone before I can route the call back to the phone. Anyone else have this issue? It seems that if the car is completely off the bluetooth should not be active. Thanks for any suggestions or help.
