Noticed my new tahoe wanted to do an update so accepted and it installed over an hour. Went back and everything seemed fine but went out the next morning and the battery was dead. Took it to the dealership, supposedly cleared and reset the system. Gave it back to me, and after stopping at the store noticed the radio was still on after the door opened. Back to dealership and after talking to GM they decided it was corrupt during the update. Installed a new module and it is doing the same thing. Anyone else have the same issue/remedy?
