Engine began to leak oil after 40000 miles. The company and dealership assured me this was normal. Longer I operated this car, more it began to leak. At first few drops, then later, 1-2 qts between oil changes. Today, it is worst. I have spent several thousand dollars related to this engine. The leaks continue to this date. Engine stopped once on me, shut off, nothing worked. No airbag, any electrical service. Hit hole in road and everything shut off. Called company many times, wrote to president, other executives all to no avail. There are many Cadillac Devilles with same leaking problem, the northstar engine has this problem since 1998, on all their models. It is like the key, they will do nothing until made to correct it. I hope you follow through, this is not right and cause many problems with deep expenses for owners.

This northstar engine has leaked oil,(not burning it) since 40,000 miles. I use 2 or more quarts of oil between oil changes. It leaks whenever it is parked. I have spent monies on this, but it appears a major engine repair is needed. Some say, the bolts were too short, and others say, this defect continued until the 2006 year.

My 1997 Deville has an oil leak due to poor engineering and results in the car dying out at any time. This has resulted in loss of power steering and brakes. I have had the car serviced but the problem quickly reoccured.

I have a 1996 Cadillac Deville that I purchased new. At about 83k miles, I noticed that an oil leak had started from under the engine. I took it in to the dealer near where I live now (moritz Cadillac in arlington, TX), and was told that the cause of the oil leak was the wearing out of the engine seals at the bottom of the engine. I was then told it would cost $1,800 to repair as it would require the complete removal of the engine from the car to repair (about 18 hours of labor). After some research on the web I found that this is apparently a fairly common problem with Cadillac's with the northstar engine. I believe this to be a design flaw in the engine, and because the cost is so high, makes it very difficult for owners to have the repairs done, and hence are driving cars that are both environmentally unsound and potentially unsafe due to the leaking oil.
Vehicle was leaking oil from several places. Took to dealer, and they put in gaskets, but it's still leaking oil.
Loose oil filter causing leakage. Mjs.
Not a safety defect but this car is leaking oil around the oil pan and from what I understand from the dealer that they have redesigned the rubber gasket to withstand hotter tempatures and I feel that this should be some kind of recall on this. The dealer is wanting $1800. 00 to repair this and my car has only 58,000 miles on it.
Leak oil after serviced twice.
