I got a PHN U1146 error this morning. Loss of onstar communication????? What can I do about this, I just got some other stuff fixed on the car(plug misfires). PLEASE tell me that this isn't expensive. I heard a loud knock like sound and then the message come on on my way to work.

What did you do to fix the plug misfires? Just spark plug wires and spark plugs? Keep in touch!

Do you have Onstar active? When did you have the other stuff fixed?
You aren't telling us much.
