Cadillac CTS Engine Problems



  • 4u2no4u2no Posts: 7
    Actually I am positive that their was no indication what so ever! I had the same exact problem and there is a Low Oil Level indicator and a oil life percentage. The percentage was always well above 50% and the low oil level didn't come on to warn me. We changed oil every three months ourselves so we know it was done properly. I had to take my car in for check engine light and the oil was dangerously low and no indication that it was getting low! This was mostly in town driving that I was doing also. That only happened like 2 times because I double checked it. Then 2 years later my engine went! I am getting a second opinion on mine. I also contacted GM customer service which was a joke! They didn't offer any help or sympathy to me at all! It is an 04 CTS with 83,000 miles. So I don't think this problem is the consumer at all. Good luck to them on getting GM to do anything!

    I have have already tried this avenue. The GM customer service rep was Caron. Case number is 71-964760776. Someone will be contacting you within 3 business days. If you do not hear from someone within the time frame, please let me know.

    VIN: 1G6DP567850217479 2005 CTS 3.6L

    I was contacted by GM and I was told "there are no recalls on your vehicle, therefore we can do nothing for you" I have owned 7 GM products, but I have found that customer loyalty has ZERO value to GM!

    I ended up purchasing a used engine and having it installed, I am bitter, disillusioned and very disappointed! I have contacted BAR (Bureau of Automotive Repair) This is a wide spread and major problem with the CTS. I feel very sad for anyone that has purchased a Cadillac CTS, if they have not experienced a problem yet....just give it some time...they will!

    I'm not sure GM even opened a "case" for me. In early April this year I called and the GM rep put me on hold while he called the dealership. He came back on and told me the dealership was working on the car. It was mostly handled at the dealership. The end result was the dealership (Ron Craft - Baytown Cadillac) gave me 5K for the car which would have been worth 10K + had the motor not cratered. I have to say the dealership was great and I have no complaints there. My issue is that I took the car in before asking where in the heck the oil was going. It would eat two or three quarts to oil between oil 5K mile oil changes. I always figured if it wasn't leaking it out on the garage floor or burning it out of the exhaust, the oil was still in the crank case. Silly me. It got to the point I was adding a quart every two weeks or so. When it finally laid down on me it had 3K on the oil change and was 3 quarts low plus one quart I had added at about 2K miles. I'm not sure I still have the VIN but will look. I'm sure my credit union has the VIN number since I'm still paying for the car.

    Don't believe everything reported in Consumers Reports as it does not provide sufficient sample information for specific vehicles. For example, there may be few Cadillac owners reporting to Consumers Reports. The best evidence that this a major problem is the anecdotal evidence from owners provided in forums such as this one and the fact that other GM owners are reporting similar problems with this same engine but in another vehicle. For example, check out the GMC Acadia forum for engine problems and you'll see this engine is a disaster in that vehicle too. Good luck with your vehicle.

    Consumer Reports does not report reliability when the sample size is too small for an accurate assessment.

    For the GMC Acadia, CR reports worse than average reliability with major engine problems for the 2007 model year.

    After reviewing your case, unfortunately due to the age and mileage of your vehicle I will have to agree with the decision made by your phone agent. I apologize for your frustrations.

  • I'm with you on the "class action " law suit against GM. Why has there not been a recall on all of these CTS engines with oil consumption problems? Too much cost to repair? Why have their intelligent engineers not corrected this problem? Goodbye GM, hello Toyota.
  • It is hard to do a recall when the cause of these sporadic engine failures has not been identified. I have suggested that defective valve seals should be considered, as this has previously caused engine failures with low oil levels in other brands (e.g. VW & Audi). I also wonder if these engine failures qualify as a safety issue, which is the usual requirement for a government mandated recall.

    safety issues, not bad engineering or crap engines.

    2004 cts 3.6 automatic, after the car sits overnight when the car is put into drive it has a 5=6 second delay before it moves. car is fine the rest of the day, only does it after sitting over night. took to dealer, tech could not duplicate it said no codes found, i know my car and it does this everday, left over night, service manager was able to duplicate it, tech again said no codes found, well duh didnt think so, i was told to do a transmission flush, i said thats not the problem some thing is starting to wear out im not paying 200 dollars for a flush only to have the problem still there and then to be told well lets try this to see if this will work, my extended warranty has 100 miles left on it, car has 89,500 miles either the friction plates or the torque converter are going, im not stupid, then i asked if i pay 200 to flush it and it still does it and you finally find its something else will i get my 200 back and was told no. this is nonsense, you mean to tell me your techs can only fix somehting when there is a code that shows, this nothing more than trial and error at my expense till they finally find the problem, what should i do, thank you, any ideas what might be wrong are welcomed.
  • Take the car to a privately owned shop (not a cheap chain).
  • hi have you had any engine issues like timing chain and oil consumption I also have a 2004 and have both problems , would like to try and get idea of how many people have 100k miles on their cars without any problems. If anyone reading has a high mileage car please share any comments good or bad. thanks
  • no engine trouble i change the oil faithfully every month and does not have oil consumption issues

    . . . i change the oil faithfully every month . . .

    Wow -- so your put is that MONTHLY oil changes are the answer.

    How far do you drive in a month? a year?

    With today's oils (just dino, never mind synthetic), oil change intervals of 5 - 7K miles are generally well regarded.
  • I have a CTS 2009 AWD 3.6. I bought a demo car. A 2009 in 2009. Since I have had the car the car eats over a quart of oil every 800 miles on the usual. More so at other times. I currently have 34,000 miles on it and have reported the problem. And they say "service guy" that that is usual and there's nothing that they can do unless it consumes more oil. That is baloney I have had 9 new cars in my 41 years of life and never have had a car ever eat oil like this. And this is not cheap oil it is synthetic. I mean to me they are just riding this out until the car is out of factory warranty then when the engines blows they will state that I am responsible for a new engine out of pocket. I have contacted Cadillac and they want me to bring it every 500 miles. I have had 3 Cadillac's in my life and never a problem like this. I am thoroughly disgusted as you state. I purchase the car new to not have these problems and support the American industry only to be screwed by the American automaker. Next time I am buying foreign. Yes they are nice at the service desk but nice doesn't fix my problem on my 48,000 dollar car.
  • I agree with you. I purchased a new vehicle expecting not to have major issues. At least you got an answer. When I asked my dealer where the oil was going they just shrugged their shoulders. Actually, now that I think about, that was a more honest response. They really don't know where it is going but they do know there is a issue with the V6 consuming oil. I wonder what "uses more oil" means? A quart a day?
  • maybe 1000 miles, but i have the oil and tires rotated every month regardless, have ever since i bought it, mainly because of the timing chain issues i have heard about,i take really good care of this car, have every reciept from the dealer for services, one thing if anything did happen cadillac cant say i didnt do maintenance.

    I apologize for the problems you are experiencing with your vehicle. Have you spoken with Cadillac Customer Assistance? If so, could you please email me your case number? I would like to look further into your situation.

    Thank you,

    I have a 2009 CTS with the 3.6 engine. I have the oil changed at 5 to 6000 mile intervals at a Cadillac dealership. It uses a quart between changes. Do not let this oil usage problem go until it is out of warranty. I would stay on this until I got GM to do something about it. My service advisor told me that one of the problems they had with the oil life monitor was its generosity between changes. He said some people change the oil, going by the monitor, and never check between changes. He told me that they recommended no more than 6000 miles; that what they were finding was the actuators were going bad at around 50000 when people were going more than that. In my case, if I went by the monitor, I would go 13000 miles between changes. It does not sound like you are doing that. Your situation is not normal.
  • no i havent called customer service, im just dissapointed that the highly trained tech cant find the problem, it does this everyday and its not normal, im affraid that the transmission will finally go bad all the way and ill be stuck with the bill, thats why i bought the gmpp, first one for 2400.00 second one for 1400.00. i take excellent care of this car oil changed every month and wheels rotated every month., my car is at della cadillac in queensbury ny 518-793-3871. just authorized to have the transmission flushed, but i know thats not going to fix the problem. thank you for reading my story and writing me.
