Sorry I searched and found no similar problem. I have a 2007 Escalade and most of the time if you turn the
radio up loud the cruise disengages. Seems as soon as it gets to a certain volume level it happens.

That is strange. Whenever I hear of a problem like this one it reminds me of a problem I had with a motor home. whenever I worked the drivers electric window the windshield wipers started up. A mechanic told me to check the ground wire to the window. Sure enough I put in a new ground connection in the door window and the problem stopped. JUST A THOUGHT.
Good Luck

I know there's a common fault with a sensor by the brake pedal which makes the cruise control malfunction sometimes. Turning the radio up with loud bass probably has something to do with it.
