I Have An Intermitant Problem. The Car Starts And Runs Fine. I Park It And Sometimes I Turn The Key On To Start The Car And There Is No Power In The On Side. No Dash Lights Or Display, No Radio Or Climate Display, No Power Windows Etc. And Of Course No Power To The Starter. If I Turn The Key Back To The Acc. Side All Of The Options Work Fine. I Have Had The Car Towed To The Cadillac Dealer 3 Times And Each Time It Gets There The Problem Is Gone And The Cars Starts!!!!!! The Dealer Has Replaced The Ignition Swich The First Time, The Key And Reader The Scond Time And They Still Have The Car Waiting For It To Not Start!!!! What Could It Be??
