I replied to another similar post also so we are not alone. My 06 DTS does the same thing. It happens when the car is still fairly cold in the morning and about a mile or two from the house. Interestingly today, the light at the same intersection where it usually does this was green for a change and I actually heard the four knocks as I was drving through the intersection while moving (albeit slowly) It has happened frequently when stopped and my kids were in the back seat and they tell me that it sounds and feels (they feel the vibration of the knock) from the floor boards, not the trunk even though it sounds like the trunk from where I sit. I only have 2k miles on mine and haven't had it in the shop yet.
