Cadillac CTS Engine Problems

  • My 2005 was doing same thing , 2 weeks ago I got rid of mine , my advice sell it or trade it while you can .
  • I did a lot of research and found that the oil problem has been reported over every model year on the three point six. One report that might be of interest was a 2013 cts with eighteen thousand miles had oil consumption issues.
    I also read that part of this is due to piston rings that are undersized. This individual had the rings replaced at the dealer cost and the engine still seized on them. Others have reported six thousand dollars in repairs from eighteen thousand miles up to eighty thousand. Unless you can afford the cost and don't mind being left stranded-other reviews tesify to computer problems, no starts-and cutting out while in motion-if you can over look these than the cts might work out for you. :lemon:
  • Ever since I traded my 2006 CTS I have been looking in car mags-there are always plenty of them for sale..Let me see the car fax. Actualy I've seen all I need to see. The Cts In my review gets a one in a possible five. I rate it only on it's styling. It does look nice, but the performance issues that are easy to research and documented puts this car in the lemon category.
    These posts serve only as a buyer beware. If anyone decides to buy a Cadillac CTS and they do not experiance the problems so many do-then they should post as well. but So far the negative comments outways the positive. :sick:

    I have a 2011 CTS and have not had any of the oil problems discussed thus far (knock on wood). I did have an earlier post where I had some early problems of the whole car shutting off on me 3 times within six months of owning it. After two visits to Cadillac dealership maintenance it seems to have fixed the problem. My guess is that there was a loose connection or short which caused the problem and the full car inspection and checking every cable solved this issue. Thus far....the engine has run well and no extensive oil use problems....again...knocking on wood. :)

    Hi there,

    Glad to hear that your '11 CTS has treated you well so far and that your dealer helped you through those few minor issues. If there's anything you have questions about, or need assistance with, please let us know.

  • I'm glad I found these series of posts to give me some peace of mind. Regardless of what some of you may think my purchase, but I happened to buy a used 2005 Cadillac CTS 2.8 from a dealership and was surprised to see the engine light turn a week after my purchase. The engine ran great, didn't feel any abnormalities with the exception of the entire car shaking when you would turn on the air conditioner heater. Pretty easy to confirm as you can turn on the AC/Heating and immediately feel the "kicking" sensation. However since I live in cold-[non-permissible content removed] Canada I didn't really bother with it, even though the car would consume more gas with the heating on than off.

    The problem I faced was three months into the purchase when driving from 0 -60 km/hour. After driving for a few months I had a pretty good "feel" as to what was normal acceleration and started feeling irregular gear shifts and "stuttering" coming from the engine. A shriek would sometimes be heard when accelerating/sounding like an awful acceleration noise.

    Since my Transmission fluid was at 14% and my engine oil was 20% I figured my transmission oil needed changing. The oil percentage was at 95% when I first bought the vehicle and I thought it was going to be a transmission problem. After taking it to Canadian Tire the mechanic told me that the oil level was dangerously low! And that by replacing the oil the issue with acceleration would dissapear. After the service the engine light also dissapeared and would not come back on again.

    I'd like to mention that prior to the service the engine light would either turn off and then turn back on, or would randomly flash occasionally.

    With the oil and transmission oil fully replaced I drove for another 4-5months only to find the "stuttering" happening again along with the acceleration grinding issue happenign again now that the car is at 24% oil life (96% transmission). After restarting the engine the "check engine oil" message came on. SO it makes me conclude that the Cadillac CTS takes much more oil than expected and the % indicator for oil should NOT ever be trusted. Thankfully I know what the problem is with the onscreen diagnostics message and the engine light coming on (it's off now), and I will replace the oil in the morning, but it's a shocker to me that the on-screen diagnostics are simply not accurate.

    Point taken - check your engine oil regularly and change the oil before it reaches 30%.

    As I've only driven for the day to experience this issue, I'm hoping there's no permanent damage. Will keep everyone one posted after the service tomorrow.

    2007 CTS -NICE veh--Vinyl top, leather seats, pin stripping, alloy wheels gleaming in the Florida sun!!
    Man, what a sight!(Better I had been blind.) !475 miles on odometer.
    Two weeks later, a scratch appeared fully along the right side. First trip to body shop. $!400.00--ins paid
    All was well until June 2011 1330 hrs(1:30 pm). While on a trip to Augusta, Ga, I killed a 200 lb buck with the front of my CTS.( all cosmetic damage and we finished our trip with hood bunged down ) 2nd trip to Body shop. $4400.00---ins paid- no deductable.
    Two weeks later, at 31000 mi, threw timing chain. Oil level was aok. First trip to mechanic.
    Two days later, call confirmed timing chain. Two days later,call confirmed bent valves.
    Four days later, call revealed cracked engine block and that I needed a complete new engine! $9050.00
    Thank God we had a 'Bumper to bumper' warranty!!!
    It ain't over yet!
    Three weeks after getting CTS back, a man backed into the right rear quarter panel in Publix parking lot. 3rd trip to Body Shop. Ins paid $1800.00 --no deductable.
    Now, we're happily driving and enjoying our Black Cloud CTS-----THEN----last Tuesday while on I 75 south bound, a miss began. Got off and stopped for a traffic light 250 ft from my destination. Engine died. 2nd trip to Mech. Two days later, Cadillac informed me that I need to overhaul the engine ($6000+) or install another new one.(9000+?!) 73,346 mi on car (42,000 mi on 2nd engine)
    Service manager(felt sorry for me) gave me the number for Cadillac Cust Care. Related this story to them and at present, I am waiting for a call back to let me know if they will help!!!!!!!!!!!!!!!!!!!!!!
    Please excuse my pessimism but---------HA HA HA Ha ha

    Happy In Florida! (Although I'm not quite sure why..???)

    PS: I have had to put 7 qts of oil in this 36L engine in less than 1500 mi
  • I entered the wrong date of the deer incident--it should be June 2010 NOT June 2011.
    FYI - actual date of first failure was 8/2010. WOW, I get to buy a new engine every 3 yrs!

    Good luck indeed. Mine burns a quart every 1,800 miles and I never got a reply to my somewhat jaded inquiry.
  • They can't diagnose it over the internet AND they can't diagnose it if you bring it to the dealership either, because I fell for that yesterday. They said, 'bring the car in, so we can hook it up to our diagnostics' So I did. GUESS how that went. According to Jeremy at autonation (gm dealer in Port Richey, FL.) they hooked it up, but wouldn't be able to tell me if the cam needed a shim, or the timing belt was gone, or the cylinder had to be replaced. To quote Jeremy, "best case scenario" you're looking at about $400, $500, "worse case scenario" you're looking maybe $2200 or more if the timing belt is worn, but I can't tell until I take the top of the motor off and see what's going on. WOW, thought you told me I had a 'SMART CAR' that would tell you what's going on 'once you got it hooked up REALLY????? 54,000 MILES, AND I COULD BE LOOKING AT THOUSANDS OF DOLLARS IN REPAIRS. Buy a CADILLAC, GM'S finest, and right after 50,000 miles, I have major problems with the motor???I'll bet when they do get your car in, you won't get an answer until they pull the engine apart, and then what will you do when they say it's thousands o dollars, and they've got you by the crank shaft???? "Put it back together" and WHAT WILL THAT COST YOU?????? to put it back the way they found it? The diagnostics is right around $100.00. But, pulling the top of the engine and putting it back???? REALLY??? TO FIND OUT WHAT'S WRONG???? I still owe 7 grand on this car, and it's gonna sit in my driveway. Well, that was my CADILLAC EXPERIENCE" What's yours????
  • Well I have heard a lot of stories about the Caddillac CTS and did not believe them until now I bought my 06 CTS in February 2012 the car only had 38,000 miles on it I heard a little ticking sound coming from the driver side part of the engine and had it looked at the maintance tech said it might have just needed an oil change so I had him do it. which of course did not stop the problem so I had spoke to a couple of friends and family mebers to ask them what they thought and of course no one really new. I kept up on the oil changes and always checked my fluids since I drove this car a lot back and forth between my home and Columbus and the car never gave me a problem just had a light ticking sound. well needless to say August 20th 2013 I was heading back to Columbus and my engine gave up and was done it blew up at my half way point to Columbus so I had my car towed to Germain Cadillac and paid $260.00 in a tow fee and asked them to look at it while I called GM I waited a month just to find out the my car was not going to be covered even though my warrenty ran out of time not mileage and now they are wanting $200.00 for the inspection they did. GM is saying that there was burnt oil and that my car threw a rod and a bearing threw the block I still owe on the car and have not had it long enough to have these kind of problems with it this is crazy I showed them where the car had maintance done on it everytime I traveled and that the oil was changed every 6,000 to 7,000 miles I am now looking to go forward with a class action Lawsuite
  • Don't get a CTS they have lot's of issues and GM will not fix them even if you do what your suppose to do to maintain them. My 07 CTS has become one of the biggest headaches I have ever had.

    Read all the posts here if you have not already..you have the 2.8-the 3.6 is famous for the engine seizing-due in part to undersize piston rings-which causes the engine to consume five or more quarts every four thousand miles.

    I had the 2006 cts kept it two weeks and turned it back in-engine shaking,check engine light-and number four injector code problem.
    What I learned reading in this forum is that all the 3.6 cts engines-even some 2013 models have extensive repairs...it is not just the engine-it's everything and everything is expensive. Read on and hopefuly you have one of the good ones-is there a good one? I traded mine for a chrysler 2007 sebring and no problems-Ill never buy a Gm product again....

    Haven't posted about my CTS in a while, but this is what I know --

    Back about 10 years ago, they began cutting corners and as we all know the gov had to bail GM out. The rings and pistons in the v6 engine they used in the CTS we're not engineered correctly allowing excess amounts of oil being burned through the rings and into the cylinders. Most engines experienced running through a quart of oil every 1000 miles or so. If you did not religiously check your oil it was only a matter of time before your engine became useless.

    GM said this massive amount of oil consumption was within normal limits. Many people who took road trips of over 5000 fried their engines after checking the oil prior to their trip. They were always told they did not maintain the oil properly.

    I would bet 1000s of people had their engines fried and the we're told it was their own fault because they are incapable of checking the oil in their Cadillacs.

    This is such a coverup!'

    FYI. They replaced the whole top end of my 2008 CTS. And the whole exhaust system as the oil in the exhaust ruined both catalytic converters!! They had my CTS 46 days total!

    You need to find a dealer committed to fighting for you.

    Sounds pretty typical. You can vent here, but there's no real help here. And if you post anything vaguely threatening the holy GM they will just delete it, or they have the host delete it. I've tried. You see, we can't share email addresses or phone numbers. I've had 30+ GM vehicles but this sight has made me hate them for basically screwing us. Good luck
