iPhone does NOT disconnect when GM vehicle turned off.

The only reason the iPhone would remain contacted to the Bluetooth in the truck is if is still broadcasting. It seems there is a problem with the vehicle turning off Bluetooth when you turn off the vehicle. The iPhone should disconnect from the device if Bluetooth isn't available.

You mean it WILL disconnect if BT is not available (since there is nothing to be connected to).

True, I'm just saying it is not the phone that is causing the problem.

I have the same issue but only began when upgraded phone to the 5S, had no problem with the 4s. IT IS THE PHONE and NOT the TRUCK.

How is the iPhone staying connected to a device with no power?

Think about it it, how can the phone stay connected to a radio that is off?

That would be called Magic.

The radio does have FM! 😁 (electronic term for when something broken simply start working for no apparent treason)

Perhaps the phone is giving a false positive on the BT connection showing a connection is still on when it's really off. I suppose one way to test the theory would be to walk a fair distance from the truck and see how far it takes to disconnect if at all.

Thanks for the GM link Chris CA...Hope the future update works for my issue. Seems to have annoyed a lot of GM owners!

With my old 4S I could be on Bluetooth and turn off truck (2009 Silverado) and pull keys out and still be connected and when my call is done it then disconnects. To reconnect I would just restart truck or turn key to accessories.

No one mentioned anything about this...

I am having the same problem. I have had the 5s paired to my Cadillac srx for a year with no problems. Suddenly, my phone is staying connected to the car after the car is turned off and I am in the house. I have missed calls since they are ringing inside my car in the garage. I have been on the phone with onstar and they think the cars' Bluetooth is not disconnecting when the car is turned off. Look at your onstar buttons, I have a green light that is staying on. On star says that is evidence that the onstar is not disconnecting. They recommend I take the car into the dealer. You might want to consider it is the gm vehicle and not your phone. I have an appointment for gm to look at this on the 25th. I'll post if they solve the problem.

I contacted GM yesterday and they said it was indeed a GM issue and that they have a solution (see below response from GM). They said it would have to go to a dealer and be updated. Hopefully this will work and I will post back whether there solution works.

Great! Hope they get it sorted ASAP...

My 2009 Silverado issue has been resolved, below is the procedure I used to fix through a GM fix. Hopefully it will work for others with different phones and vehicles.

On the OnStar device press the phone button once and wait on response

Then say "Digit dial" wait for response

Then say "star key" wait for response

then say 22890 dial...you will have to say each number one at a time and wait for response then continue with numbers. Once done with numbers say dial.

if done correctly you will hear a voice confirming and reprogramming OnStar. Once complete turnoff vehicle remove keys and close door. Re-enter vehicle and give it a try.

MAKE SURE YOUR PHONES BLUETOOTH IS OFF BEFORE BEGINING.

Hope this helps others!

This worked perfectly for my 2009 Traverse. Problem was driving us nuts for about 2 weeks. Thanks for saving us a visit to the dealer.

If you follow the steps in coastalwetlands post right before this one, dated 9/24/14, it reprograms OnStar and stops the problem where Bluetooth won't power off. We too had problems where the car would answer phone calls with the car off and Retained Accessory Power off as well. My wife was wondering why she could not hear anything after the phone rang. She only figured out the problem after hearing my voice coming out of her car in the driveway.

Thanks again to coastalwetlands for posting the solution to this very peculiar problem.
