CTS Howls and Whines

2006 Cadillac CTS 4dr Sedan (3.6L 6cyl 6M)
My CTS howls and whines at all speeds and RPMs. Cadillac states that this is 100% within its standards and is characteristic of the vehicle. This does not give me peace of mind that the car is operating safely.
The exterior looks and color (Blackberry). Very easy to navigate in traffic.
Fix the differential, engine, transmission pump and exhaust system to curtail the howling and whining noises.
