Started with a few drops of oil from under engine, keeps getting worse. Dripping oil getting on exhaust or other hot fixture and burning smell comes into passenger compartment unless air reicirc is turned on.
I've spoke to a couple of other DTS owners and they have the same problem and from the reports here and on other sites I cannot believe this hasn't been made a recall.

Oil leak from the lower crankshaft. Cost $2,553.00 to repair. I have not had it repaired. Do you think GM knew about this problem?
Have been told the gasket at the pan is bad and to fix the motor will need to be removed @ apx. $2,000. The tech I spoke with had worked at a Cadillac dealer up until 06. He said oil leaks were always a problem with Cadillac. Would think this should be a GM problem....any ideas. Charles

Dealer pulled engine and did a total fix for $1,000.
Great deal for me. Also fixed several other items.
Oil leak started small and grew. I initially thought it was just a poorly installed filter. Started before 50,000 but I didn't get it to the dealer. They now say $4,000.00 to repair, Cadillac offered $1,900.00. When I spoke to Cadillac customer service (a misnomer)I also complained heated seats failed, poor high speed braking (severe chatter especially on downhill grades-I changed front brakes rotors and pads to a non-GM brand and this reduced greatly even thought pads were not worn out) and lumbar support in driver's seat inoperable. They said "out of warranty." I now have clunk in front end at low speeds and no memory driver's seat function. $52,000.00 and it has more problems than a Yugo! I have always bought American maybe it's time to change.
I bought this car new in September 2005. The dealer has performed all maintenance and repairs. I first noticed small amounts of oil on the garage floor at about 45k miles. I took it to the dealer and the diagnosis was a leaking gasket between the block assemblies. The technician recommended a complete engine reseal at a cost of $4,000. I went to the local auto parts store and bought a $10 drip pan. I’ve owned Cadillacs since 1993 and think this one is my last.
Update 3/12/2011: After some price negotiation, this baby is going in the dealership shop Monday morning for a reseal.
Dealership found right rear valve cover gasket leaking oil onto exhaust manifold.
removed and replaced gasket with new o rings.
car under warranty, no charge.

Ever increasing oil drips on garage floor. Noticed earlier (while still in warranty) but thought it was filter leaking after oil change. Leak continued, took to dealer. Quoted $4,000 to repair. Contacted Cadillac and told them of the many problems with the car even at this low mileage (heated seats quit working, knock in front suspension at low speed). They offered 1/2 on engine repair. Not very co-operative. Informed me I was out of warrantee, tough luck. Note: noticed oil on floor while still in warranty but to dumb to run to dealer!!!
