On Oct,30,2017 I was sitting in the car with it idling. After about 10 minutes the car started registering "hot". the dash board said it was running hot. The thermostat hand had moved to the red point. I cut the car off and waited for about 5 minutes and started back up and drove it to crest dealership. At this point the hand or needle had gone back to normal level. The customer service person informed us that it could be the gasket. We left the car with them and was told 2 days later that it was indeed the gasket going out and would cost around $6300 to fix. The problem is that the car is serviced on a regular basis, oil changes, winterized belts checked, etc. I have had numerous problems with the engine and had it fixed. The car has about 45,000 on it. This engine has given more trouble and I have spent a lot of money. I feel that the engine, which is a northstar engine and is a "lemon" and should be recalled. I should not have to spend so much money on getting this car fixed and I keep it up to date on the maintenance of this vehicle. Please take to the time to contact crest Cadillac in nashville Tennessee for my records.

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 took it to the dealer and the diagnosis was a leaking gasket behind the oil filter housing.I replaced that gasket and oil still leaking from the oil pan engine housing.have been told the gasket at the pan is bad and to fix the motor will need to be removed @ apx. $3,000. Cadillac dealer and GM knew about this problem in 06. But no recall. 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. Just type in Cadillac Dts oil leaks on the internet and you will see the problems with these cars.

We have owned this Cadillac since Feb 2010 (approx 28 months) and have had this vehicle back to the dealer 16 times. Each repair requires a rental vehicle, anywhere from 2-5 days per service visit. We have had 7 wheel bearings replaced and 12 sensors replaced. There doesn't seem to be a day when the service engine light is not on. The quality of this $52,000 automobile is very poor. The vehicle is back at the Cadillac dealer now, with coolant & engine issues once again.
