How long has your 2009 Cadillac DTS had this problem?
RepairPal Certified shops can diagnose and repair your 2009 Cadillac DTS. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Without personal *hands-on* testing - ALL we can offer here 'online' is a guess.
One *possibility* is there is an EVAP problem causing the engine to flood after fuel tank fill up.
Try HOLDING accelerator pedal to floor while cranking engine.
Highly recommend contacting local auto repair facility to discuss repair arrangements.
NEVER 'top off' fuel tank when refueling!
