Cadillac CTS Engine Problems

  • I, too, am having major problems with oil consuption on my 2005 CTS 3.6L engine. So far my dealership is getting GM to pay for it. Initially, a year ago when I bought the car it was throwing codes for cam followers, which they replaced several times. Then they found that there was no oil (3 weeks after I bought the car). My service manager has been working with GM, who says that the piston rings and valve stems need replaced. My extended warranty won't cover it because it doesn't cover oil consuption issues. GM recommended that the engine be decarboned first. It went back in today because it is 3 qts. low in 1200 miles and GM is recommending another decarboning. Has anyone had the problem corrected and if so, what was the fix.

    Tell the dealer to find a creative way to write the service order so that the warranty will cover it. Was there any type of dealer warranty when you bought the car? Since the car is still having the same concern that it had 3 weeks after you bought it that warranty, if there was one, should still be covering all the repairs. Just a thought.
  • Please help. I see that there have been many issues with the CTS engine using too much oil and that leading to major engine problems. Last week my car's engine stopped running without any warning. It has 40,000 miles on and is still under factory warranty. I had the oil changed about 4600 miles ago and have a receipt and had it checked about 1,400 miles ago with written proof from my local shop where I get get my gas. I am told that I need a new engine and GM won't cover it because it only had two and a half quarts of oil left in the engine when it was towed in. I wanted to buy American and Cadillac is the flag ship of GM. What good is a warranty if they don't cover it? The service department said the oil should be checked every 2 to 3 thousand miles. I was inside of his recommendations. EVERY time someone gets their oil CHECKED they better have the attendants write it down for proof. You wonder how GM can treat their customers this way. We can't let them get away with this kind of customer service. I will never buy GM again. No wonder they are in BIG TROUBLE. Has anyone with problem got it solved the correct way without an attorney? I will get one if neccesary.
  • Im planning on getting a 2005 cts tomorrow...i dont know if i should??? Especially reading all of this!! I love this car..:( what should i do
  • your story sounds just like my sons except he has only put 9,000 miles on his cts since he bought it with 28,000 miles on the car. The engine blew with no prior warning or indicators and the dealership where he bought it says there was a lot of sluge and low oil but he checked the oil just minutes before it blew cause it knocked loudly at start up. The dealership where he bought it doesn't want to honor the warranty but will pay him $6,000 for the car if he uses that money to put down on another car from them. Sound fishy? I think GM needs to be held accountable for poor product. Did you ever win your battle?
  • 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...

    Hi,

    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'
  • 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.
  • paopao Posts: 1,867
    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....
  • temj12temj12 Posts: 450
    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.
  • paopao Posts: 1,867
    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.....

    I am looking at an '08 CTS DI AWD and after reading through all these engine issues I am VERY hesitant to continue my Caddy Quest. I currently own a '98 Regal GS Supercharged. Around 60k miles, the car started shutting down while driving, similar to what I'm reading here about the CTS engines. It would restart again after 10-20 attempts and seem to run fine. No mechanic could ever figure it out, and then one day, it just never happened again! The car now has 212k on it and is running like new still (except for slight bearing rattle from Supercharger nose). I would have sworn that they 'program' these problems into the engines. :)

    I may take the CTS for a test drive and just LISTEN to her. Thought about BMW, Infinity, Acura... but have always owned domestic (no real reason) and love the look and power of the CTS, especially with the DI.
  • paopao Posts: 1,867
    most of the issues here appear to be engine lock from low oil...as I read the more recent ones....not sure you will see that problem if at all in the new design CTS...08 and beyond.......quite happy with my 09 CTS with 23 k on it now
  • gm_bigotgm_bigot Posts: 19
    I have a 2007 CTS (3.6L) with 30K miles on it. I change the oil at around 7500 miles or so. I always check the engine oil level prior to the change just to see if there is an oil consumption issue. Never seen it down even a half quart.

    Good afternoon. I am sorry to hear about the problems you have had.
    The main reason why I have decided to reply to your post is souly due to the fact you are ( or were ) thinking the same thing I have been. Class action lawsuit. I normally wouldnt be saying this but GM needs to own up to some of this. I have a 05 CTS 3.8. with 58,xxx miles. I bought mine from a local dealer here is St.Peters Mo. I decided to buy it from a reputable Cadillac dealer ship, come to find out it didnt matter. The Cadillacs all have issues along with the dealer ship and GM. We had our car maybe a month and noticed that it was running wierd, not necessarily knocking but hesitating. After bringing it to the dealership almost 3 times they finally fessed up and said that the water pump was bad. About another month went by and the car started doing the same thing. Thank God I hopped on line and seen all of this. I'm not the most knowledgable about cars but I know enough. At this point the car only had 50,xxx miles on it. Need less to say that I only put 3 or 4,xxx miles on it after I bought it. The dealer said they just changed the oil so I didnt think about that. After I seen all of this I checked the oil to realize it was at least 3 quarts low. I was shocked, I have been checking it regularly and I add about a quart every 2 weeks. This isnt normal, I traded my Honda with 130,xxx miles on it for this. WOW. Thanks GM for screwing us loyal AMERICANS!!! What do I or we do now? How unfare would it be to sell this to someone and dump this in their lap? If you are a cadillac owner with these issues, your stuck. We need to have GM cover this. Lets stick together and get our problem solved. If anyone gets together for a law suit, I want in...Good luck...636-295-5672
  • I wanted to take a quick minute and let everyone know who reads this that if there are so many of us Cadillac owners who have had issues, there has to be someone out there who can help get this resloved. Whether it be by hiring a lawyer, everyone of us calling GM or even the most extreme... Picketing !!!! This is just insane. if anything we need to make the public aware of these issues. The typical Cadillac owner wont buy this car with the understanding that they need to check the oil regularly, at least not with in 3 or 4,xxx miles. Its common knowledge that if you run synthetic oil you can go longer than 3,xxx miles. Thats where I believe the problem comes in at. When I bought my used Cadillac the dealership said no worries. You dont need to change the oil but every 8,xxx miles. If your Cadillac burns oil like mine, by the time you hit that 8,xxx mile mark it will be to late. This is not my first post. Come on people, lets stick together and get something resolved. Good luck and God Bless....vincebange@yahoo.com
  • Since this happened to my car i have been warning everyone I see driving a CTS . I was telling a lady at the gas station about this problem because she was driving a CTS and we checked her oil which turned out to be about 2 quarts low and that blew her mind . I called an engine rebuilder and he laughed at me and said they have a policy of not rebuilding Cadillac engines period .

    I purchased a used 2003 Cadillac CTS with approx 59,000 miles in Oct 2009. I was not offered a extended warranty. First thing was the truck brake light had to be replaced. Next it was the engine light on because the dealership did not put the gas cap on correctly after gasing it up for the purchase. I did have my first complementary oil change done at the dealership where I purchased the car. The mechanic did not have any recommendations for the oil change. Then the low level antifreeze light came on.....filled that, light went out. Meanwhile the car would shake a little while idling at a red light....and the car would burn a LOT of gas. Keep in mind the car would operate but it had a slight shake while idling. Once in a while I would smell burning oil through the car's air vents. Then a few minutes later the smell would go away. On March 26, 2010, while driving on the highway without warning, the engine light came on, the car was shaking so bad I thought the car would cut off. The shaking would "calm down" a little if I did not excel over 50 mph. But if I excelled to 60 mph the shaking would get VERY rough as to cut off. When I took it to my mechanic I was advised at first the diagnostic code was misfire on cylinder #3 and #4. Both of the ignition corals had to be replaced. Once I agreed to the repair, he then called back to advise that the valve cover gasket was filled with oil.....causing cylinder #4 to be filled with oil and was dead and cylinder #3 was coming on and off. The recommendation was "car has a dead cylinder #4 has 90 psi will need a motor". I have only had the car at this point for 6 months, I have only put 5,000 miles on the car, and it gets better.....I am still financing it!! HELP!

    Very sorry about your experience. Did you have the car checked by an independent mechanic before you bought it?

    Also, in a 6-7 year old car, I think that what you needed was a dealer provided warranty rather than an extended warranty.

    In any case, when buying a used car with a very poor reliability record (see Consumer Reports), it is best to be very very careful.

  • The car I am referring to is a 2005 so it's only 5 years old . I did have a mechanic look at it and we fixed some other issues . If there was any question as to if this is a unique issue talking to the engine rebuild company removes all doubt. The lucky people that had this problem got their dealerships to manipulate their warranties to cover them but I wasn't so lucky. It is still my opinion that this problem is known to GM and they are not going to address it unless forced to .

    I'm at a loss. I bought a 2007 CTS 6 months ago. Currently it has ~25,000 miles. Every morning I back out of the driveway, put it in drive, and then start down the road. Consistently the first 100-150 feet the car hesitates like it is having trouble getting up and going, and then it kicks in and I feel the car surge forward. I took it to the dealer a month ago and they said nothing was wrong, but that I needed 2 quarts of oil (onboard computer said I was at 59%). Two weeks later I took it back and they said it was a worn timing belt which was replaced, and they did an oil change. I took it back two days ago b/c it has still been hesitating and I heard a strange knocking noise on Monday morning while it was hesitating, and again they said nothing was wrong. Other than kidnapping one of their mechanics so that they can sit in the car at 530 in the morning when it acts up, I don't know what to do. The 3rd visit was to a different dealer than the other two visits, and he thinks there is nothing wrong. It only does this first thing in the morning after a cold start. I blamed winter at first, but the last couple of weeks it has been 50 degrees or warmer in the morning.

    I dont know what the problems are with my car. I have had it for a year now and the same problem seems to persist, it's a rattling noise in the engine compartment. I have had it in the shop 5 times and now my warranty has run out and I am stuck and dont know what to do. first 3 times was the timing chain that had to be replaced after 2 months of my owning the vehicle. then I have gotten the runaround, having them fix some other things, so they say. But it's the same thing, when I go up a hill or I am low in gear, I lose power and it sounds like a big rig. Doesn't help that after 6 months my dealer that I bought it from closed up and can no longer sell GM products, hmmm... I am upside down on the car payments if I trade it in and I have no place to turn.

    please respond if you can help me out

    thank you
