  • Not so sure . Bought an 05 cts with 55k on it. thought finally a good car that our family wont have to worry about. Got the oil changed around 3000, and i was told that it was using about 2 quarts but not to worry that it was normal for that engine. One day it developed a rattling noise so i took it to buck chevy in canalfulton. they did diagnostic and told me it was because of the bad battery huh? I was told they trannie was electronic and that the new battery fixed it. Soo drove it for a while but the same was happining... so i checked the oil nothin ... I added 5 quarts of oil ,,, with only 2k from my last oil change it wouldnt accure to me check the oil.. now i need a new engine. so anyone know how new of an engin i can put in a 05 cts. I would like to set it on fire in front of our local caddy dealer

    heyburt,

    I apologize for the problems you are experiencing with your vehicle. Do you currently have a case set up with GM Customer Assistance? If so, could you please email me your case number?

    Thank you,

  • OK. Reading all of these posts about oil consumption and expiring engines is giving me an upset stomach. I have a 2007 CTS with the 3.6L engine with 46K miles. I've changed the oil every 6K-7K miles. No oil consumption issues at this point. However, I'd like to hear from some folks with older cars with the 3.6L that have over 75K miles who have not had any problems. Any good news out there??
  • So I had the same issue with my 2005 CTS and found a fix. Go to the dealer and state that your cadillac is burning through oil at an unreasonable rate. They will ask you to do an oil consumption test, which consists of paying for a new oil change ($90) and then coming back in 1500 miles to see how much oil has been consumed. Here is what I did.... I drove the car like a mad man for the first 1000 miles. Heavy on the gas to burn as much oil as possible. The car can handle the heavy driving and it's actually not a bad idea to burn out the old build up.

    Then at 1000 miles I removed the oil plug for a few seconds and drained a about a 1/4 of the oil remaining. Place the oil plug back into position and MAKE SURE you have at least enough oil to cover the first hole in the dipstick. Continue driving for another 500 miles to build up gunk on the oil plug so they can't tell you have drained it and make sure to monitor the oil amount along the way so that you don't drop too low.

    I took the vehicle back to the dealership 1500 miles after the oil change and guess what... They performed the cadillac service needed (about a $3500 repair) for free and my car has run like a champion ever since. Performance is better and you can feel the response difference due to all the new seals etc. I don't lose a drop of oil between changes now and never have any excess oil burn. It was a tricky way to get it resolved but I've had several friends do the same now and we all have great working caddy's. Good luck!

  • "Then at 1000 miles I removed the oil plug for a few seconds and drained a about a 1/4 of the oil remaining."

    You fabricated an oil level in order to get Cadillac to work on your problem?

    How much oil were you actually burning?
  • MAKE SURE IF YOU ARE GOING TO KEEP THIS CAR PLEASE BUY THE EXTENDED WARRANTY. THERE IS ONLY GOOD NEWS YOU SHOW THE DEALERSHIP A COPY OF THESE COMPLAINTS AND THEY GIVE YOU THE EXTENDED WARRANTY.
  • i love my cadillac 2006 and it has 106,000 miles on it with no problems except the thrmostat gave up twice. the first time i bought a new one at the dealer and the second one after market at 96,000 miles. now listening to all you guys i am getting exta, extra worried. the cadillac is using way too much synthetic oil. actually i forgot to check for 6 months and luckily i found out when the engine started making weird noises. i measured the oil and the dip stick came out dry three times. as of 9-21-11 i put in 4 quarts of pennzoil synthetic oil.
    At 106,000 miles is it ok to use non-synthetic oil now. thanks guys. let us keep the pressure on GM.
    My first american car was a used ford escort, lasted for 2 years. this is my second american car bought brand new. i am having secon thoughts---will stick to foreign cars
  • The good news is it seems you have escaped the pain many of us have gone through. So far. The really good news is that you should have no trouble trading your car for another year/make/model that does not have this kind of history. Get while the gettin' is good, friend.
  • Yes I did. I had to add 1 to 2 quarts between oil changes and with synthetic oil thats ridiculous. EVERYONE with a CTS has this issue of burning oil and the car should not being running that way. I can personally tell you the performance and oil level is 1000x better since the fix. They virtually replace every seal in the engine. I strongly recommend this as an easy way to get your car in proper working condition. Even if you're burning oil like I was they generally come back with a "normal oil consumption" result on the test. Not this time :)
  • I was out on another Cadillac forum and I read a posting from a guy who has a 2005 CTS that was burning a couple of quarts every 1000 miles or so. This guy obviously knows something about cars because he made a modification to his PCV vacuum tube (don't ask me to explain what he did), and apparently the engine no longer drinks oil. So that got me looking around again on the web and I went back to the old reliable: technical service bulletins on the CTS. Apparently one was issued in May 2011 that talks about oil consumption. Finally! Right? It mentions only 2006-2008, but I suspect this can apply to all of model years with the 3.6. At least we now have something to wave in the face of the dealership when they say, "Oh, that's normal" or "We don't know where the oil is going". See below.

  • Why is cadillac going to admit this is a crap engine? I dont think so . So can you at least tell me what years will go in my 05 with the least amount of change. I still owe 10k on the crap car. so it has to last till its paid of.
  • lwwlww Posts: 1
    No good news. My 2005 started using 1 qt every 1000 miles at 55k. I had to have the engine replaced at 87k (covered under extended warranty). New transmission at 125k, new cats/oxy sensors at 130k, new radiator at 150k, new coils at 160k. I now have an apparent ecm issue at 168k (car won't start; key won't come out). My 2005 Sierra has a similar litany of problems. After having owned GM products all 38 years of driving, I'm DONE!
  • what do ya think???

    lww,

    Could you please email me your VIN and current mileage? I would like to look further into your situation.

    Thank you,

  • 05 CTS 89k on it. Changed my oil before taking a short weekend trip (appx 962 mi.). Using Mobil 1 full synthetic, still I dont know why, got home from my trip and had to add 2 full quarts to TOUCH the dipstick. Usually between recommended service intervals my car ONLY consumes 2-2.5 quarts of liquid gold. THIS IS RIDICULOUS! This is just as bad as GM's transfer case problems, which they were fully aware of BEFORE they were put into production. Does anyone know of a VERY GOOD Corporate attorney that would be willing to file a class action lawsuit? I have a little moneyb to burn and would sure like to get the ball rolling. NEVER EVER going to purchase a GM product again, and will do anything I can to stop others. Tomorrow the car is going to be parked right in front of Dealer with a giant LEMON on the roof. I will be there telling everybody about GM's "NO RECALL OR TSB, so no problems exist policy.

    klamper,

    I apologize for the frustrations you have been experiencing with this concern. Have you taken your vehicle into your dealership to have an oil consumption test performed on it? If not, this would be the direction I would recommend towards resolving this concern with your vehicle.

  • I see GM is suggesting you have an oil consumption test done at the dealer. At least GM is doing an oil consumption test now. My service writer just shrugged his shoulders when I suggested the car was consuming oil. While it's good to know some folks may be able to avoid the hell I went through, you gotta know I wish I hadn't had to go through it myself. Oh well.........always blazing a trail here. Somebody has got to walk point.

    I suggest you observe the strategy employed by mrvr2u mentioned earlier in this thread.
  • I have had the same problem with the Cadillac CTS and the oil consumption that I am reading about. My car is 6 years old and has less than 28k miles on it. I have had regular oil changes and now my engine blew. Cadillac doesn't care and I am out alot of money and basically have to trash this car (which is otherwise in mint condition). I will never buy a Cadillac again. I have already contacted an attorney and I am interested in filing a class action suit against Cadillac (GM). Who is on board with me?

    Using the forums to organize legal action isn't permitted.

    Additionally, class action lawsuits generally take YEARS to resolve, and in the end the consumer often gets a settlement in the form of either 1) fixing the issue (on a vehicle they likely no longer own by that time), or 2) something like a $500 off voucher toward your next Cadillac vehicle purchase.

  • Didn't know you can't use these forums for that. Well, I already have an attorney working on it for me. I find it disgusting that Cadillac can get away with this. I wish I had known before it happened (unfortunately I didn't go around googling information about the Cadillac until it happened). If I had known, I would NOT have bought the car off the lease. I would have turned it in and bought a completely different (probably foreign) car.

    carolsue1,
    I apologize for your frustrations. Can you email me your VIN and current mileage? Have you had an oil consumption test done on your vehicle? I look forward to your response.

  • I have had Onstar since the day I bought the car. My "remaining oil life" is tracked and I have receipts from every oil change I have had.

    It is too late, my engine already is gone even though my last oil change was in June (1,800 miles ago) and I have 27.5 miles on my car.

    Sorry, but dealing with another GM Customer Service representative is really a waste of my time. It is in an attorney's hand now.
  • Wow, using the word "tricky" to describe what you did is very imaginative. It's called "fraud" where I come from. We all pay for those $3500 tricky fixes.
  • If any one else is having the oil consumption issue read this article , seems the SRX is also having the same consumption issue as the CTS BUT in this case GM confirmed this is normal, when I talk to Cadillac customer service they had no knowledge of any oil consumption issues although my dealer and another dealer were very open about it and said it was quite common with all GM products with the 3.6L engine.

    This engine is also in the GMC Acadia where it's having problems and it's in the Chevy Camaro. For 2012, the Chevy Impala gets it. Looks like GM is dropping all of its OHV V6's (3.5, 3.8, 3.9) for the sake of a modern twim cam V6. I'll take the simplicity and reliability of old tech over modern new tech any day!

    Have you found a solution to your problem? My check engine light just came on with the #4 misfire and 300 code. Injector 4 was replaced but it didn't solve the problem. I am ready to get rid of the piece of junk but I'll have to park while it is at least running on 5 cylinders until I find something new. I'm not putting another dime into this piece of crap. Good news is, it isn't burning oil yet but I would guess that's next.

  • I've been reading everyone's posts about how poor the GM cars are (and especially the Cadillac CTS). As previously written, I have had the same problems and my car has been at the dealer for over 3 weeks now. They are useless and GM is useless (don't even bother sending the GM rep your VIN #, etc.; it's a waste of your time). Just chalk it up to a bad experience and/or sue GM and certainly don't ever buy a GM car again! That's what I am doing. I am in the process of suing GM (Cadillac) and the dealer that sold me the car. In the meantime, I went out and bought a Toyota. Good luck to all with the lousy Cadillac CTS!

    Thank you for responding but I am no longer a prior GM purchaser - I just traded the vehicle for a Ford. I have/had $62,000 on the car. I will tell you the issues with the car asside from the few recalls on it. There was a bulletin issued on the grinding noise in the rear. I had it repaired under warranty. All they did was change the oil which lasted for 10,000 miles. I called customer service to notify them of the problem and they said it was out of warranty but if I took it to the dealer for a diagnostic check they would see if they could pay for anything but would not commit to anything until I spend $150 to diagose a problem that we all know what it is. We just keep changing the oil ourselves. Than, my airbag light came on and spent $671 to fix it. Waited for the recall so I could get reimbursed, received the recall form & received reimbursement, than a couple days later the airbag light came on again. My guess is that it wasn't fixed properly the first time but I was told by the dealer they won't pay for it again. My check engine light came on a few weeks ago showing showing the misfire in #4 and I spent $300 to fix that (not at the dealer or it would have probably been triple). This didn't work and was told it could be the ECM which is a $500 part but that may or may not work. Oh and yes, the tires lasted about 30,000 miles so needed to get new tires which should have lasted at least 60,000 or you would hope 40,000. Bottomline, after reviewing all of the forums, etc. it would appear the car is ready to start using oil so we limped it to the Ford dealer, got close to Nothing on trade but at least we didn't spend several thousands of dollars replacing the rear, repairing/replacing the motor, fixing the airbag, oh yes, the driver's side heated seat. Oh and yes, our mechanic called Cadillac regarding the entine problem and they told him they weren't aware of any issues. That's pretty much what I had gotten every time I called. From all the complaints you know darned well there are problems with this vehicle and you do nothing. As you can see I am venting but GM should be ashamed at this quality and no service. Of course, my fault, I didn't buy an extended warranty. Just want to add that I am not an aggressive driver, serviced the vehicle every 3,000 miles, used Mobil 1.
