#70 of 721 05 CTS New Engine
Dec 26, 2009 (12:35 am)
Bought an 05 CTS in June 2009 with only 32,000 miles and boy were we in love! Then the first $85 oil change...one month and 3000 miles later another $85 oil change...and so on and so on. This being the only real complaint we were still in love with our baby! Then the beginning of the end--the coolant level was low appeared on my screen. Hubby replaced missing fluids and back to lovefest. Light came on the following week--no possible way we lost that much fluid in under a week and there were no leak spots in my driveway! Not sure what miracle my husband performed but the light quit appearing. Then about two weeks later I grabbed the kids and a girlfriend and headed out shopping--made it to the end of the block before I heard it suddenly start knocking!!! Hubby checked all fluids--no problems! Great --on a Sunday afternoon--no open service center! The next morning my husband had to call in because this being our only car would not be seen til the following day. Tuesday morning took it to service center. That afternoon we were called to pick it up and were given a recommendation- a repair shop who dealt with the Warranty Company we paid extra for! Wow--thank goodness for that small favor! A check diagnostic revealed: Engine has a spun Rod Bearing! I got my car back Dec. 23--Merry Christmas to me!!! I found a new mechanic who is a great man and works wonders with warranty companies! Aren't synthetic blend oils more expensive in part because they last longer--anywhere from 3000-5000 miles between changes? We are adamant about 3000 miles and the one time I let it go a little over 4000 miles my car needs a new engine? Is the honeymoon over? Not yet--had a 2010 Toyota Corolla rental for the two weeks my baby was at the spa and DAMN was that AWFUL!!!! I am spoiled now----Will totally investigate everything for my next Cadillac purchase--but there will be more in our future!

You are not alone. The same exact problem happened to me on Dec 20, 2009 while returning from a Xmas party. I had changed the oil on my 2008 CTS at 25000 miles and at 26,000 miles the engine blew up. GM says it happened because the engine had no oil and they refused to honor the warranty. My car even caught fire at the exhaust pipes and had it not been for a nearby gas station where we parked and put the fire out, the car would have exploded.
After reading so many problems with oil disappearing from CTS engines I believe there is a basic design problem with them and a class action lawsuit should be discussed among all of us with the same problem.
Anybody has any other alternatives?

I can't believe anyone would pay that kind of money for a dream car and then not take care of it. The computer lets you know when to change the oil. That's a no brainer. Maintained my car and had timing chain problem. Ken Batchelor came through and stood behind the car. Take care of your car and it'll take care of you.

are you saying you did your first oil change at 25K?..09 CTS with 22K on it...and no evidence of oil useage at all....I have the non-DI engine...
#74 of 721 04 CTS Engine Failure
Feb 09, 2010 (2:19 pm)
I'm sad to say I get to join many others who's engines have failed. After first great mid-Atlantic blizzard last week I started my car (80K mi). Terrible noise from the top of engine. Checked oil, reading was normal. I have it changed every 3K mi.
Thought it might be head gasket seal that had allowed antifreeze into oil. Got it to my mechanic who did tested oil and antifreeze and said it was fine. He drained oil and changed filter. he said the oil was black, heavy sludge, and carbonized particles. (last change was 2k mi ago) Filter has trace particles of metal, apparently oil is not getting to lifters, he said it might be clogged channels...etc. Anyway engine is shot.
Never got any indicator/msg. Called my salesman who gave me Caddy number. They've opened a case, want to look at it at dealership...
Now I wait. Granted product is out of warranty, but catastrophic failure without warning!
I lost over $15K when GM bondholders were wiped out...
Mechanic say Honda is best car out there...
I love the CTS but I might not be able to afford this kinda of 'quality'
#75 of 721 No warning for low oil defect
Mar 03, 2010 (1:16 pm)
My 2005 CTS with no previous problems and no warning lights on started to hesitate so I pulled into the first gas station once I got off the toll road . The engine was at least three quarts low on oil . the engine oil life still says 25% life left and no oil pressure light was on . I started it up this morning and now its knocking . The mechanic says it needs a rebuild job . this problem sounds like an engine defect that GM knows about but doesn't want to acknowledge .

I did not had any engine trouble on the 2005 I had, but my friend did. His engine went out at 30,000 miles. He bought it used and it had the certified 100,000 mile warranty. I am wondering, too, if Cadillac has a problem with their engines. I rolled into the dealership with my 2009 CTS with 8,000 miles for the first oil change. I talked to the service advisor and he said that they were now recommending 6,000 mile oil changes; they were having problems with some of the engines at 50,000 miles. He said not to go by the monitor. My monitor would have let me go at least 10,000 miles.

the question is who is "they" that are recommending the 6K oil change....most of the issues I see here are for low oil/oil consumption by the older MY CTS engines...and lack of warning light indicators......I would ask did the oil pressure guage give any indication of a problem?....
I too have an 09 CTS with the non-DI engine.....I check oil levels in all my cars monthly, along with tire pressure and air filters.....just part of routine maintenance on my part.....oil changes are all sythnetic, done by the GMOL usually around the 6-7K mark or about 25-30% on the indicator.....have 3 GM vehicle....04 Chevy with 160K, 06 Pontiac with 40K and the 09 Cady with 22K on it.....and follow the above process with all three.....no issues at all with any of them oil related....

I am certainly not saying that I let my maintenance go. I, too, check the oil on a regular basis. That is just common sense if you want to make an engine last. When I had my 2005 CTS, I went to the Cadillac dealership to get the oil changed at 5,000 miles. He told me that was not necessary because it was synthetic, and that I needed to go by the monitor. I asked the dealership on the last oil change if they were still going by that recommendation. At 8,000 miles, mine was at 40% and I just did not want to go any further. He told me that they, the Cadillac dealership, were now recommending 6,000 miles because what they had found was that, if you went by the monitor and the number of miles it allows, they were beginning to have engine problems at around 50,000 miles on some of the 08's and 09's. They attributed this to people changing their oil in the 8,000 to 10,000 miles range.

OK so it was your specific dealership that recommended the change......did they specify what kind of engine problems they were encountering.....Im sure some of the 08s and a few 09s are in that mileage range now....just wondering the population size of the dealership's "08/09" engine problems they are basing this recommendation on....and why they directly attribute it to not changing the oil on a more frequent basis...as opposed to a service bulletin released from GM with such a recommendation.
My driving habits dont allow me that 8-10K range between changes even using the GMOL....which I usually let go to the 25-30% range before I change (6-7K range)...I also wonder if the problem engines have used a synthetic or dino oil?....I beleive the new CTSs come with synthetic in them from the factory now....I run only mobil 1 or pennzoil platinum synthetic in all my cars.....and have no problems at all....
Im just always leary of a dealership pushing their "own" service schedule vice that of the manufacturer.......all of em do it if you let them.....havent seen a dealership yet that doesnt have a nice little flyer at the service desk with their own specific schedule....which most of the time is far more stricter in frequency and services than listed in the owners manual.....
