Cadillac CTS Engine Problems

  • Why don't you post your contact info so people can call you directly , the people on this forum are very upset with the way GM Cadillac is dealing with their concerns and I have had the same experience. You are in no position to help any body so why don't you stop wasting peoples time and giving them them false hope.
  • I have a 2005 CTS 3.6 and it has the same problem with oil consumption. I'm much older than you and have owned dozens of vehicles in my lifetime and have never had the experience of 600-800 miles per quart of oil as I have with my CTS. The Cadillac dealership service manager told me that was in range for Cadillac. Sorry to hear that this is still a problem with the 2009 model. One would think that the engineering dept. would have this issue resolved by now.
  • AMEN! the GM service people told me "there are no recalls" or TSB's (technical service bulletins) therefore there is nothing we can do for you!
  • CTS ....acronym for Cadillac Truly Sucks!

    Head gasket problems on the old 2.2 found in the Cavalier's and Corsica's lasted for most of the 90's. Intake manifold gaskets blowing out on the 3.1, 3.4, 3.5, 3.8, and 3.9 V6 engines has been happening for the past decade. GM's track record on resolving major engine issues is not very good. Best of luck.
  • What is the oil capacity of the 3.6 engine???? The 3.5 V-6, alum blocked, 4-valve engine used in the Intrigue and Aurora between the yrs of 1999 through 2002 was 6.5 qts..Owned 2 Intrigues with the "Shortstar" engine and did 75k on a 99er and 120k on a 2002 w/o any problems.

    Did switch from Mobil to Pennzoil which helped eliminate the adding of oil between changes, every 3k..With Mobil usually 1500 mile was a qt low..Both cars were 90% driving on open highway at 75++..Caddys owned were a 91 Deville Touring Sedan w/4.9 V-8, 1996 Deville w/Northstar, and a 1999 Deville w/Northstar..Never added any oil between changes..

    I see the 2012 Impala has the 3.6 engine rated @300hp..Pricing starts around $25k, kinda takes the prestige out of the Caddy chatter!!! Love those corporate engines..Caddy engines in a Chevy!!!!

    My experience with the above owned models was satisfactory, the 91 got a new engine at 59k miles, gift from Cadillac due to piston slap..The Caddies were the wife's..I only drove them on Florida trips and to the dealer..

    Current Caddy pricing is "out of the ball park", no value!!!!!!!
  • I had the same experience with my 2006 STS, it was using over a quart of oil every 1,000 miles. The dealer had me bring it in every 1,000 miles for a total of 3,000 miles to document the oil usage. After that they changed all the seals in the engine under warranty. This fixed the problem. You might ask if your dealer can do the same thing.
  • The 304hp V-6 current offering has a crankcase capacity of 6qts..Called my friend at the Caddy dealership..

    The 215hp "short-star" V-6 of the Intrigue and Aurora was 6.5qts..

    Won't run the CTS/STS too long at 80+++, might go to trash....

    Cadillac family, I have appreciated the forum discussions but last month I decided to do something that I don't regret...I got rid of my car before it got rid of me! Some off the information that was mentioned I experienced and it is very true, trying to get Cadillac (GM) to come to your aid is like searching for gold. For the most part my CTS ran pretty good for me but I wanted to be the one to quit before it quit me. So, I took it to CARMAX and they rewarded me handsomely. I plan to stay within my car family Toyota and get me the LS 460L. It was good communicating with you.

  • someone should call the local news then drive their caddy through the front window of the dealer.
  • 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,
    Caron, GM Customer Service
  • 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 :)
