  • In Canada 4 liters of oil at the dealer are $ 56 and I think the oil change needs 7liters. Plus the filter Plus the labour. Even at a retail store Mobile 1 synthetic is $12 for a 1 liter container or $ 49 for 4.54 litres.
  • Since my problem with GM I have already convinced two people not to purchase any GM vehicles. I can not wait for the day for this company to collapse. To many complaints & they still refuse to help worst customer service ever.

    With my CTS, the problem that I have is the smell of something burning all the time. I have looked for leaks, but can't find one. One day I saw smoke turn the heater off no more smoke, but the smell still come when I drive the car. Anyone having this type of problem?

    If you travel by car to the U.S. on a regular basis bring back a 5 qt. jug of oil. It costs about $29.00 U.S. at WalMart for Mobil 1 5W30 synthetic. It's a lot cheaper to provide your own oil than to buy the oil in Canada. Good luck.

    I had the exact same problem lasr year. The dealer replaced the alternator which didn't fix the problem. A nechanic here on my farm traced it down to the brake calipers. First one was replaced and eventually the second. Feel the calipers when you get the oder and I bet they will be very hot.

    I have a new 2011 Cadillac CTS with 1700 miles on it. Yesterday, I was driving 60 mph on a highway, and the car just cut out completely -- only the radio kept working. I must have felt the car decelerate, because I looked at the dashboard, and it was totally dark. Luckily, I was in the right lane and traffic was light. I was able to maneuver the car onto the shoulder. I tried to restart the car, and nothing happened -- It didn't even make a noise. It was like someone unplugged the power to the car. A few seconds later, I tried to restart the car again, and it started right up and ran fine. The dealer has the car now and is trying to determine the problem, but has not yet figured it out. Has anyone had this issue? Does anyone know someone who experienced this with their car? Any ideas? Thanks.
  • i am having the same problem with my 3.6 v6 burning oil and has been in the shop now 3 times for smoking when i excellerate quick, dark smoke, i have black soot all in my tailpipes and only have 30,000 miles on the car.

    do you have the direct injection engine or the base engine....

    Sarah, The service department said they can't find anything wrong with the car and they test drove it for 80 miles. They said it must be a software anomoly, and they downloaded software. The car is a deathtrap, and Cadillac is not taking responsibility for it. Who should I contact, and how?
  • Yes, so glad to find you. The day (1-2 weeks ago)I drove my 2007 Cadillac CTS from the service department for having timing chain & passenger side airbag recalls (supossedly) fixed...my car has been making new strange noises and added a burning smell that I cannot locate. Under 76,000 miles~~maintenced properly. I can only speak for myself~~I bought a Cadillac for not just luxury also for RELIABILITY. I am a divorced single mom who all the way (4yrs) of RN school and waiting tables when not in class said to myself, "When I get my first RN paycheck I am going to reward myself with a Cadillac." Well I got a Cadillac...
    but no reward.

    There are good reasons for buying a CTS. However, if reliability is a top priority, then it may not be a good choice. Consumer Reports indicates that reliability of CTS has varied from average to much worse than average over the years. Major engine problems have developed in older models.

    CR is a good source of this type of information, and has helped me make wise car buying choices for decades. The on-line subscription is particularly helpful, as it provides detailed information on reliability, road tests, etc. Note that I am just a long time CR subscriber, and have no relationship with CR.
  • If you haven't already done so, I would ask for you to send us an email using the information in my profile here on Edmunds. My coworker Christina generally responds to the incoming emails from Edmunds, and so you should hear back from here over the course of the next few days. Another option would be to call the Cadillac Customer Assistance Center at 800-458-8006. They're open 8am-9pm EST, Monday through Saturday.

    Best,

  • Wow! I just bought a 2005 CTS about 2 and a half months ago that just had an oil change before I bought it and we checked it and it looked fine. Oil wasn't supposed to be changed for another 1500 miles and the car started sputtering and wanting to stall. No warning lights came on but a friend checked the oil and it was DRY!!!! Now I'm reading about how terrible this kind of engine is online and don't know what to do. It's no longer under the dealers warranty but I have just started receiving extended warranty offers. I just don't know what I should do! I'm SO surprised at how this is all coming from Cadillac: a vehicle with such a good reputation!
  • Good morning,
    I'm sorry to hear about this oil concern you've encountered with your new CTS. Have you had an oil consumption test performed by your servicing dealership?
    Sarah
    GM Customer Service
  • No, this just happened two days ago and I immediately took it to get an oil change. I am taking it back in a week for them to check and document the oil usage. At this point the dealership has just washed their hands of the vehicle and I am left to figure out what my rights are and how I should handle this.
  • Sarah-

    I've been alerted to this discussion, and it is of great concern to me.
    I bought a 2004 CTS (new-in 2004), and now have 14,600 miles on it. Yes, 14 THOUSAND 6 HUNDRED. The car has never seen snow. It's been in the rain only a few times.
    I do change oil after 2,000-3,000 miles, ignoring what the instument panal tells me regarding oil life (it usually has 50+% oil left remaining when I do change oil).
    I did have to have the computer changed, as the security system would not disable, not allowing car to start.
    My concern now is this oil issue I am hearing more ansd more about. My friend had an issue with her 2005, and it has less than 30,000 miles.
    Am I to expect the same issues that I've been reading about? I'd like to know the view Cadillac is taking on this.
    Thanks-

    NAD
  • I understand your concern; hopefully the following information on oil consumption is useful.

    All engines require oil to lubricate and protect the load bearing and internal moving parts from wear including cylinder walls, pistons and piston rings. When a piston moves down its cylinder, a thin film of oil is left on the cylinder wall. During the power stroke, part of this oil layer is consumed in the combustion process. As a result, varying rates of oil consumption are accepted as normal in all engines.
    The accepted rate of oil consumption for engines used in the vehicles referenced is 0.946 liter (1 qt) in 3200 km (2000 mi).

    Our dealerships will evaluate the consumption of a vehicle based on a variety of factors to determine whether or not the consumption is abnormal. If you should have further inquiries on your specific vehicle, please get in touch via email (please include the last 8 digits of your VIN).

    may claim that a quart of oil consumption in 2000 miles in street service is normal, most don't. I am in possession of three cars with engines that don't use more than a pint of oil in 5K miles, two of which have over 100K miles on them, and the third of which is a Honda (Acura, actually).

    Something is seriously wrong with the design of this engine. The rest of the car appears to be wonderful, but this engine thing is killing it.

    The real cherry on the sundae is that the oil consumption increases exponentially before "the event," after which the engine is toast. Checking your oil weekly, even in between gas fills, won't help if it's your time. Even if it used <1 qt in 2K miles, in the next 200 it may use 3, after which. . .
  • I just took my cts in today. 70,000 miles. I had the check the oil in the engine when they drained it. Short 2 quarts/ 3,000 miles! They are going to replace the rings and pistons with redeveloped ones. I am going to file suit. This is a covet-up! It should be a class action suit!
  • I have a cadillac cts. Since I took the car in for service before a road trip, I've ben having problems. The dealer did'nt put the proper amount oil in the car. When I end at my destination I was 4qts of oil short. I've been having a problem every since. Now it's back at the shop for engine problems. I wish I had never bought that car. The car is a 2005 and it's running bad.
  • After I paid the car off, I found out that the car had been in a front end accident and it was never disclose. I think it's a danm shame that a dealer has the right ti take your money and never discose anything about the history of a car,
  • If we can follow up with your dealership for you, we'd be happy to do so. Please get in touch via email (include your name and contact information, the last 8 of your VIN, and the name of your dealership).

  • I am a 2005 CTS owner and have been since 2007. This car is sharp to look at but there is where it ends. I've posted on this site before and have dealt with gmcustomerservice and cadillac about the oil consumption problem and brakeing issues. Part of my brakeing issues were resolved but others still remain. The oil issue is the one that has really upset me the most. GM sent me to my Dealership to have an oil consumption test conducted. They really did not know how to tell me what to do since I had to keep up with checking the oil at every fillup. I had to read the SOP to figure it out myself. When I brought it in to be checked (since it had used oil to the extent that it needed to be filled back after only about 1000 miles) they put it up on a lift to check underneath and told me it had a leak around the timeing chain housing and they couldn't do anything about the oil problem until that was fixed at a cost of $1400. HOW CONVIENIENT!!!!! I've had this car since 2007 and never have I seen a drop of oil anywhere where I park and I park in the same spot every day. I'm 62 years old and have owned multitudes of vehicles in my life and never have I seen an engine use oil like this one. I have a young friend that has purchased a 2005 STS with the same engine. I told her to be aware of the oil problem and to check it often. Well she apparently forgot and one day her car wouldn't start. She called her Dad for advice and he told her to check her oil. Well, low and behold, she was 4.5 quarts low. The same thing had happened to me after my first oil change. GM, what are you going to do about this problem!!!!!!!! I'm not paying $1400 to continue this process when I know that is not where the oil is going!!! Have you not read enough posts from CTS owners to know there is a serious problem!!!!!
  • I have had the exact same issues. Although I had to resort to installing a used engine, the 3.6L which still eats oil. GM/ Cadillac has been unresponsive to all of these posts and concerns. Sarah (GM Customer Service)has tried to be helpful and understanding, alas, I feel she does not have the power to affect any change in the GM customer service, or lack thereof. I am pretty sure the American people bailed this company out! I am out $4000.00 for a used engine! For anybody that has a CTS (mine is a 2005) get rid of it, before it's too late!

    Just an update on this. The dealership returned the car to me 4 days after I brought it in. The dealership could not determine the problem and made an assumption that it was a software issue. The dealership downloaded new software, but did not want to replace the computer. Cadillac corporate customer assistance put me in touch with 2 GM district specialists, one of whom told me that if the problem happens again (and there is a car left after losing all power at 60 mph), that the dealership would look at it. The other GM district specialist told me that I need to have faith that the dealership fixed the problem, even though they could not locate the actual problem. When I bought the car, I had faith that it wouldn't lose all power at 60 mph. Barring identification of the cause of the problem, that's all the faith that Cadillac is getting from me. I filed a complaint with the National Highway Traffic Safety Administration, which administers recalls, because if I did have a software problem, so too will other 2011 CTS drivers. And I got rid of my 2-month old Cadillac CTS at a significant financial loss, but at least I don't feel as though I'm driving a deathtrap.
  • The best advice would be to trade it an run before the used car market catches on to the design flaw with the GM V6 motors. I started to buy a Camaro RS until I realized it had the same motor as my 05 STS which was destroyed from the inside out due to this unmanageable oi consumption issue. The only other thing I can think of is to install a "day tank" in the trunk and top it off every time you come home. Good luck.
