Cadillac CTS radio display shows starting disabled with stalling and engine shutdown issue after ignition switch replacement on Cadillac CTS

Some Cadillac CTS owners report experiencing issues with their radio display showing "starting disabled" after an ignition switch replacement, which may indicate a problem with the VTD system disabling the starting system due to a message from the theft deterrent control module. Additionally, some owners face stalling and engine shutdown problems that could stem from a dead battery, damaged starter, fuel pump, alternator, or engine. In instances where the car shuts off and displays "Starting Disabled - Remove Key," gently lifting the throttle pedal may help the vehicle restart. It is advisable for owners to check the battery and verify the condition of the starter, fuel pump, alternator, and engine. If problems persist, seeking assistance from a professional or contacting Cadillac is recommended to ensure proper vehicle function and prevent further complications.
