I've been alerted to this discussion, and it is of great concern to me.
I bought a 2004 CTS (new-in 2004), and now have 14,600 miles on it. Yes, 14 THOUSAND 6 HUNDRED. The car has never seen snow. It's been in the rain only a few times.
I do change oil after 2,000-3,000 miles, ignoring what the instument panal tells me regarding oil life (it usually has 50+% oil left remaining when I do change oil).
I did have to have the computer changed, as the security system would not disable, not allowing car to start.
My concern now is this oil issue I am hearing more ansd more about. My friend had an issue with her 2005, and it has less than 30,000 miles.
Am I to expect the same issues that I've been reading about? I'd like to know the view Cadillac is taking on this.

I understand your concern; hopefully the following information on oil consumption is useful.
All engines require oil to lubricate and protect the load bearing and internal moving parts from wear including cylinder walls, pistons and piston rings. When a piston moves down its cylinder, a thin film of oil is left on the cylinder wall. During the power stroke, part of this oil layer is consumed in the combustion process. As a result, varying rates of oil consumption are accepted as normal in all engines.
The accepted rate of oil consumption for engines used in the vehicles referenced is 0.946 liter (1 qt) in 3200 km (2000 mi).
Our dealerships will evaluate the consumption of a vehicle based on a variety of factors to determine whether or not the consumption is abnormal. If you should have further inquiries on your specific vehicle, please get in touch via email (please include the last 8 digits of your VIN).

may claim that a quart of oil consumption in 2000 miles in street service is normal, most don't. I am in possession of three cars with engines that don't use more than a pint of oil in 5K miles, two of which have over 100K miles on them, and the third of which is a Honda (Acura, actually).
Something is seriously wrong with the design of this engine. The rest of the car appears to be wonderful, but this engine thing is killing it.
The real cherry on the sundae is that the oil consumption increases exponentially before "the event," after which the engine is toast. Checking your oil weekly, even in between gas fills, won't help if it's your time. Even if it used <1 qt in 2K miles, in the next 200 it may use 3, after which. . .

I just took my cts in today. 70,000 miles. I had the check the oil in the engine when they drained it. Short 2 quarts/ 3,000 miles! They are going to replace the rings and pistons with redeveloped ones. I am going to file suit. This is a covet-up! It should be a class action suit!

I have a cadillac cts. Since I took the car in for service before a road trip, I've ben having problems. The dealer did'nt put the proper amount oil in the car. When I end at my destination I was 4qts of oil short. I've been having a problem every since. Now it's back at the shop for engine problems. I wish I had never bought that car. The car is a 2005 and it's running bad.

After I paid the car off, I found out that the car had been in a front end accident and it was never disclose. I think it's a danm shame that a dealer has the right ti take your money and never discose anything about the history of a car,

I am a 2005 CTS owner and have been since 2007. This car is sharp to look at but there is where it ends. I've posted on this site before and have dealt with gmcustomerservice and cadillac about the oil consumption problem and brakeing issues. Part of my brakeing issues were resolved but others still remain. The oil issue is the one that has really upset me the most. GM sent me to my Dealership to have an oil consumption test conducted. They really did not know how to tell me what to do since I had to keep up with checking the oil at every fillup. I had to read the SOP to figure it out myself. When I brought it in to be checked (since it had used oil to the extent that it needed to be filled back after only about 1000 miles) they put it up on a lift to check underneath and told me it had a leak around the timeing chain housing and they couldn't do anything about the oil problem until that was fixed at a cost of $1400. HOW CONVIENIENT!!!!! I've had this car since 2007 and never have I seen a drop of oil anywhere where I park and I park in the same spot every day. I'm 62 years old and have owned multitudes of vehicles in my life and never have I seen an engine use oil like this one. I have a young friend that has purchased a 2005 STS with the same engine. I told her to be aware of the oil problem and to check it often. Well she apparently forgot and one day her car wouldn't start. She called her Dad for advice and he told her to check her oil. Well, low and behold, she was 4.5 quarts low. The same thing had happened to me after my first oil change. GM, what are you going to do about this problem!!!!!!!! I'm not paying $1400 to continue this process when I know that is not where the oil is going!!! Have you not read enough posts from CTS owners to know there is a serious problem!!!!!

I have had the exact same issues. Although I had to resort to installing a used engine, the 3.6L which still eats oil. GM/ Cadillac has been unresponsive to all of these posts and concerns. Sarah (GM Customer Service)has tried to be helpful and understanding, alas, I feel she does not have the power to affect any change in the GM customer service, or lack thereof. I am pretty sure the American people bailed this company out! I am out $4000.00 for a used engine! For anybody that has a CTS (mine is a 2005) get rid of it, before it's too late!
