  • Update to all following this: I finally received a reply from the above mentioned cust service rep. I was told my "case" was closed due to them unable to reach me. That is very interesting considering I never received a call or email response from anyone.

    The case is now reopened and I will supposedly receive a call within 24-48 hours.

    Not holding my breathe.

    I will keep you all posted.

    I am happy I could assist you in getting things together on the right track with your case. To anyone who has a case with GM Customer Assistance, you should speak with your agent weekly or bi-weekly, or after any dealer interaction.

    I just received word that our 04 cadillac 3.6 was blown with the exact same problem.It was low on oil and jumped timing ruining the engine.In my case the oil had been changed on a very timely basis.I would bet it still had 60 % usage left on it .the car itself only has 47k miles.Has anyone had any success with gm fixing these engines.I am take very good care of my vehicles and there is no reason on my part that this engine should go .I always used Mobile 1 and changed the oil on more than a regular basis.The garage said it was very low on oil but no light or any indication that any thing was wrong.Any suggestions?
  • Wow I am so sorry, this is the exact same problem I had with my 05 3.6L. I too changed my opin frequently, the last time being a month before the "blowout". I can't believe with all the issues the 04-05 have had, they didn't do a recall. I'm sure GMs focus is more on sales vs taking care of their existing customers. You should open a case with GM. The more of us that speak up about this issue the more likely they are to take action. Good Luck and pleae keep us posted. I will do the same.

    The 3.6 Engine is becoming infamous like GM's old Quad 4 engine from the late 1980's and 1990's. Check out other forums (e.g. GMC Acadia) and others have similar problems with this engine. Good luck.
  • Update on my nightmare dealing with GM:

    I just received a call from another incompetent rep. He called to put me on hold for 10 minutes, then got back on the phone to tell me the Supervisor is not available right now. Really? So he called me to put me on hold then tell me I can't speak to anyone yet. This is amazing. Where do you find these people?

    I have yet to speak to a supervisor.

    I understand your frustration. After looking through your case I see that your agent has asked you take your vehicle to have it diagnosed by a GM dealer. This seems to be the hold up with your case. You have your vehicle diagnosed by a GM dealer your agent (or their supervisor) can then plan a course of action to get your concerns taken care of. As every major company we have standard operating procedures and having the vehicle diagnosed is just that. This helps us to get technical information on your concerns. Please feel free to contact me or your agent once you have taken your vehicle in to an authorized GM dealer.

    Wow. That the same response I got from them. By the way, when you take to the dealer and they claim that it's your fault (which they will) you will get to pay the dealer for the diagnostic. This is what happened to me. I then brought the car to an independent shop for repair and they sent the heads out for repair to an ASE machine shop, who broke them down, piece by piece and they found a design flaw. Go figure. GM wouldn't even look at the report. Good luck.
  • I have experienced almost all problems discussed in this forum and sympathize with all those who are suffering. I had an '05 CTS 3.6 with 67K miles which I just traded in this past weekend and salvaged $9000 before the inevitable engine failure. Here are some of the problems I had:

    Occasional rough idling since day one.
    Coolant leak/broken water pump in second year.
    Differential leak twice.
    Went through 3 batteries in 6 years.
    Creaky suspension when going over bumps.
    Whining noise when going at low speed - 20~30mph.
    Severe shaking and smoke out the pipe when starting in the morning from time to time.
    Occasional shaking when stopped at a light.
    OIL CONSUMPTION (1 quart every 500~600 miles) the last few months.
    Worst dipstick ever. It's colored black, so you can't really see the dark oil on it.

    I've had a positive experience with an '02 Chevy Astro, so I won't say I'll never buy another GM car, but I'll be more hesitant in the future. For sure however, I won't purchase another American luxury car because of the horrible resale value; the loss is just too much. For comparison, my friend just traded in his '06 Civic LX with similar mileage for $12K.

    I maintain my cars very well and usually make necessary small repairs here and there and drive them for long time, but I didn't want to take a chance with the engine on this CTS. Good luck to all awaiting resolution.

    Worst dipstick ever. It's colored black, so you can't really see the dark oil on it.

    The fact that you know what the dipstick looks like, unlike so many who post here, is why your engine never went completely south. You've also confirmed what I've believed -- high oil consumption that, if ignored, leads to total engine failure.

    Wonder why some of these engines work so well and others don't? It's not as if every one of these engines is a dog. Either they (GM) know and don't want to say, because the cost of fixing all of them is prohibitive or, worse yet, they don't have a clue.

    Either way, you dodged the bullet. Better luck in the future!
  • Update on my nightmare: After finally speaking to a supervisor, accomplished nothing.

    I am not willing to pay out of pocket to have my car towed & diagnosed by Cadillac knowing they will never admit fault. I'm sure that is a can of works they'd rather not open, as it will cost them hundreds of thousands to admit to a faulty engine for an entire fleet of cars having the same issue.

    At this point my only recourse if to purchase a new/used engine and (a) drive it for a few years to get my money out of it or (b) sell it as quickly as possible and never look back.

    I can't speak for all GM's but I can assure you this was my first and last Cadillac purchase.

    Good luck to those in the same position. I at least feel better about the situation knowing I am not alone in this.

    My 06 STS V6 just let go at 80K miles. No compression. Metal shavings in the valve actuators. I had the same mysterious oil consumption issues but never had low oil pressure indications. I was told the car has a low oil pressure safety switch which kills the motor on low oil pressure. Does anyone know if this is true? Dealer wants $10K for new motor (a 5 star Cady dealer). That ain't happening. Calling Detroit today. If I had bought 07 it would be under the new 100K mile drive train warranty. Good luck to us all.
  • Sorry to hear that...sounds like we are all in the same boat. My 05 CTS still sits in my driveway now collecting dust. I've spoken to a few shops and they all had a hard time locating a used engine. The best they could find was this: HI-for-Sale/lot-24746790/Graham-Washington

    The dealer wants $7 for a short block alone. I don't have 10k do drop on this P.O.S but if I sell it as is I'll get nothing. Cadillac offered no help unless it was 07 or newer. We're all screwed basically. Spend 7-10k to repair it and hope I can get a couple years out of it....or sell it as is for a couple grand while I STILL owe 3k on it. Either way I am loosing allot of money on this purchase that I made only a year ago.

  • Sorry to hear about the problems - - - my engine went last August, and I have a 2006. No lights, no warning, and we were on vacation. I left my car in Nebraska until I could get answers from GM. Eventually, they came through with a new engine but it took 2-1/2 months without my car. I had 56K miles and my car had just gone out of warranty. I had all my service done at our local Cadillac dealer, which probably saved me. GM did a huge amount of checking before they agreed to a new engine. I still think it was the timing chain that went and caused the rest of the damage. At this point, I don't know whether to keep the car or not. When I read of your problems, I am thinking it might be best to sell it. I have a new warranty on the engine, so I thought that I was kind of safe.

    If you got a new motor you are probably okay until you sell it, I guess. It's about time to trade it anyway, yes? Mine went in to the dealer at 60K running rough. They said it was and three quarts low on oil. The car was between 5000 mile oil changes. I should have traded it on the spot then. I just put my wife in a 2011 Malibu LT today. She loves it. GM is really trying to move the Malibu and Impala. right now. Good rebates. Dealer cash. Impala goes away for 2012 and debuts with a new design in 2013. Of course, the world ends Dec 2012 according to the Mayan's, so what's the point. ;)
  • I agree! I took my Caddy Cts 2005 3.6 car to the dealer with what I described as a weird Vortex kind of sound comming from the motor. I was stumped having been told by my dealership to go by the oil-life monitor and not the dip-stick. DUH ! I was told I was 5 quarts down but my oil-life monitor was still reading 28% I was totally taken off gaurd-5 quarts low did I hurt something? Earlier last year after having the car and putting my first3000 miles I set up my first oil change. When I arrived they checked the oil life monitor and sent me home saying it's not time(at that time the oil-life monitor read 51%)come back when the monitor reads under 10%! Something has to be done and too many people have a very plain and simple problem! I'm really thinking that if something goes terribly wrong with my car because of this problem I will seriously find a great lawyer and go full-boar after the appropriate party! :mad: :mad: :mad:

    Sell it. Trade it. Get out of it. The next thing that happens could be total motor failure (like mine). My dealer treated me pretty fairly all things considered, but you could be on the hook for all of the diagnostics ($2K plus) and then and easy $5K plus for a rebuilt or junkyard motor (they told me $10K for a new GM motor). It's not worth it. I was over two months without a vehicle trying to figure out what was going on. I should have traded mine the first time the oil mysteriously disappeared. Newer Cady's (07 and above) have 100K drive train. Run, mama! Run fast! Good luck.

    maddcaddymama is right! Sell it as fast as you can and don't look back! My engine completely siezed (2005 w 80k miles) and I had NO luck finding a used engine with a warranty that exceeded 6mos. The dealer also told me $10k for a new engine. They were of no assistance to me whatsoever! Luckily I fount a buyer for that nightmare, who gave me $6k for it. Not near what it's worth but considering it needed an engine I took what I could get for it. I was not willing to invest another 5-10k in a completely unreliabe vehicle that might drop dead on me a year from now. That was the first and last Cadillac I will ever buy. I am now in the Market for a Honda, Acura or possibly and AUDI! Good Luck
