  • Hey

    We just encountered basically the same thing with our 2007 Acadia. Timing chain had jumped and GM is going to cover the new timing chain but are saying they will not cover the damaged Cylinder Head.
    I was just wondering if you got anywhere with them covering your engine repair?

    My wife got this message and shut the car down. Restarted and it ran fine for a while and then came on again. Took it to the dealer the next morning and they just called and said motor needs to be replaced. Want approval for 9 hours to tear down and think it may be sludge buildup from improper maintenance? If so, not covered under powertrain. Has 90,000 miles. After doing some research, it seems that sludge is an issue with this motor. What should I do? I have a call into my attorney.

    Gave the authorization to pull the motor and see what the issue is. Call GM customer service and opened a case file. 71-1178413754. May know by the end of the day what the issue is.

    After posting back in January and trying to resolve our issue (engine sludge), GM stated the problem was100% our fault and informed us that they voided the remainder of our warranty. We did further research with the original dealer and found out that the vehicle went in at 21,000 miles and the front half of the engine was replaced (cams, lobes, and timing chain) for the same issue. The dealer stated the back half of the engine was not touched as per recall/technical bulletin regarding timing chains (the back of the engine is what currently failed). This tells me that there is very obviously an engine problem with this engine. Our vehicle's engine worked when we dropped it off at the dealer for repairs. We had the vehicle towed from the dealer when there was nothing more they could do for us, the engine does not run. It just sits in our driveway as we pay monthly on our loan. We have tried numerous times to correct this matter w/ GM customer Care, they no longer take or return our messages. With driving around my 4 children, there is no way I would not keep my vehicle in perfect running condition. GM, however, has put my family at risk by refusing to fix THEIR KNOWN engine problem on a vehicle that was UNDER WARRANTY! The BBB was not able to help us. I feel our only recourse is to get an attorney involved. I need a reliable vehicle for me and children. Any advice is greatly appreciated!

    Hello everyone! I am very upset and scared waiting on the dealership to get back to me on what the heck went wrong with my car. I was driving uphill on the highway yesterday when my wheel locked and the car shut off. Thankfully I had just barely hit the exit. Tried jumpstarting and the car made a rattling noise but would not turn on. Had to get it towed to my home. I find out I still have a limited bumper to bumper warranty (expiring in August) on this certified pre-owned vehicle (purchased October 2012). Which I'd thought of the Roadside Assistance last night and not paid out of pocket for towing. In any event, dealership instructed me to call GMC Roadside Assistance and car was picked up at my home and taken to dealership. Just got a call back this afternoon and they said 'your engine seized. We wont really know what caused it until tomorrow so can't get you a rental just yet. There was metal in the oil'. I hope this was not their way of implying that I could have somehow caused this to happen. They provide all the maintenance on my vehicle. It is up to date. Oil life was still at 80%. I am sick to my stomach as to what they are going to call me back with tomorrow. Anyone think they know what could have happened here? They just had my car in their shop 2 weeks ago for that recall (hose leak). Praying whatever it is is covered under warranty. :sick:

    The same thing happened to my wife and I on Thursday. GMC called today and said the oil had metal shavings in it. I too am afraid they are trying to imply owner negligence. Not sure what to do/feel. We had to prove that we had our oil changed regularly. We were told that we were 3 quarts low on oil. Just earlier in the week I checked to see that our oil life was at 51%. No oil light or check engine light came on at all. They told us that they would make a determination tomorrow on whether or not we would be covered by warranty. I do find it very odd that the same excuse/reasoning is being used with two different GMC customers on the same day. Ours is a 2011 and we did buy it from the dealership. This seems to me to be a very odd coincidence. :sick:
  • magetromagetro Posts: 4
    Exact story. I will circle back later with response from GMC dealer's service dept. please let me know what you are told. Something isn't right here. My car was just fine prior to me taking it in to them for that water pump recall repair. May be a coincidence but odd same thing happened to you. :mad:

    One thing I did do was send an email to GMC yesterday ( informing them of my issue and dealership response. I have yet to receive a confirmation or reply but perhaps you should do the same? Wouldn't hurt to log your issue with GM as well.

    GM's 3.0 or 3.6 liter engines have severe problems after 50k miles. Check out Edmunds Cadillac CTS engine problem forum. The Cadillac CTS has the same engines as the Acadia. The 3.6 liter engine has 3 timing chains. The timing chains have a tendency to stretch leading to catastrophic engine failure. My guess is that it has something to do with the timing chains. Good luck.

    I'm sorry to hear that you had to have your vehicle towed to the dealership. I understand that unexpected repairs can be extremely inconvenient. Please keep us updated on the vehicle prognosis.

    On Saturday we were driving home from the beach when our 2010 Acadia with 61k miles died. The engine quite, the dash lit up and that was all she wrote. Lights still worked etc, but the engine would only click. We had it towed for $300 to our local dealership and they just called to tell us the engine has seized. I'm gathering all of our oil change records now (all have been done at the dealership or at the local Sunoco station) and then we find out where to go from here. How strange that there have been three of these incidents in less than a month!

    My engine was replaced under warranty. I am not confident that all is well now. Got my vehicle back with new engine Wednesday evening. Saturday 'Service Stabilitrak' light comes on and off sporadically. Later 'check engine' light and low tire pressure indicators. In addition car is a bit sluggish starting up. I had OnStar run a diagnostics and was told an engine misfire was detected (Code P0300). They suggested I not accelerate too quickly, tow any heavy things (trailer or similar) and take it back to GMC for servicing within 7 days. I took it back today. They said whatever was causing the engine misfire must have pushed or cleared itself because trouble code was non-existent today. Hesitated starting is a result of battery. I now need a new battery and new tires. I've had this car 8 months. This is crazy. What else will I need to replace soon? I am at 55k miles and until 2 weeks ago all was well. Sounds like this is the mark where these cars start having issues (after 50k) :mad:

    Hi nnylidoj,

    I am sorry to hear that your engine has failed. You should still be within your vehicle Powertrain Warranty-- so under normal circumstances, this would be fully covered. Please let us know if there is anything we can do to assist through this time.

    Thanks Amber. Just heard back from the dealership (love the service team at Jeff D'Ambrosio in Oxford, PA) and they found metal throughout the engine. We just had to show all maintenance records and the engine is being replaced under the Powertrain Warranty. A bit nervous about a new engine but fingers crossed all ends well.
  • gmcustsvcgmcustsvc Posts: 4,251

  • We had the same issue as the others described here only our Acadia is a 2011 with 31k miles. There were absolutely no problems at all leading up to the engine going out. We had just driven about a 120 miles, made a couple of stops along the way. Arrived at our destination took a quick trip to the grocery store, again no issues. About 2 hours later following dinner, we were taking a short ride to the local Home Depot. Prior to leaving, we heard a clicking noise but didn't think much of it. A mile away, we heard a loud pop and then it was like I was driving on ice. Engine stopped, I lost power steering and brakes. Lights and interior display working fine. Engine would not click. Someone offered assistance by jumping battery but it wouldn't charge. Car was towed to a local Chevy dealership (Best Chevrolet, Easley, SC) as there wasn't a close GMC dealer and key left in drop box as they were already closed for the day. I arrived next morning 15 minutes after them opening at 7 AM. The service advisor was very nice and told me they would check the vehicle quickly as they were not scheduled to be very busy that day. He stated he would call soon with an update. When I had not heard anything by 11:30, I called him. He told me they were still trying to figure out what was wrong but they suspected it was the engine. I asked how much longer would it be before we knew what was wrong. The service advisor told me probably 2 hours, so I well why don't we say 2 PM. I never received a call and had a family member take me to the dealership. We arrived at exactly 2:52 and asked to speak with the service advisor. Of course he said he was just about to call me. I could see my Acadia out back, not being worked on and thought perhaps that was a good sign. Boy was a I wrong. They still didn't know exactly what was wrong with the car and to make matters worse, advised me they weren't sure why it was towed to them rather than a GMC dealer and we would need to have it towed to one. They gave me this line about they were told by their Regional Operations Manager, they could not work on it. I was also told we would need to drive to the GMC dealership to get a rental car. All this after they had my car for over 7 hours. I questioned everything they were telling me because it just didn't make sense. I agreed to having the car towed at no charge to me to the GMC dealership about 25 miles further away but I didn't understand why they couldn't give me a car rental. They said it was because they didn't use the same car rental company as the other dealership. I asked to spe3ak with the service manager. Suddenly 5 rental cars were available and ironically, from the same car rental agency as the GMC dealership uses (turns out they use the same company and fleet of cars). Given this was now 4:30 PM, the GMC dealer said they would have to call us on Monday since they were closed on the weekend. My husband called them today and guess what, they believe it's the engine and would be removing it to determine exactly what the problem is at this point. We have already filed a complaint with GM customer service regarding how the Chevy dealership handled the situation. Very concerned and confused.

    We waited 9 weeks to get our 2007 Acadia. We finally got it March 3, 2007. Ever since then we have been living a nightmare!! This Acadia has had nothing but problems & also is a moving target. I have had my lift gate replaced over & over again. I was in a bad accident in 08 and had to have both of my front & rear end replaced, both mufflers, my air conditioner, my gas tank, ect... I have been 5 accidents all rear ended & once this year hit a deer & had my front end replaced again! Back to the problems it came roof leaked. Rain water would pour in through the dome lights, sun roof, and just about everywhere else!! I paid over $400. Dollars to have it fixed! I had it fixed over 4 times. The dealer was nice enough to cover the last 3 repairs. From all the water it blew out my radio & blew my speakers, again the dealer was nice enought to cover the repairs. The radio & dome lights would not go off when the car was off, again paid to that fixed. Had to replace my second air conditioner, again paid to fix that! Then my dome lights would not go on when you opened the door, paid to have that fixed too! When we would put gas in the Acadia or go to start it after is sat for a while & it would not start. It would kind of start & then die, paid to have that fixed! My windshield fluid would not come out, paid to have that fix too! Now my radiator is leaking (& there is a recall for that but GMC will not repair that because again we are over the milage & have no warranty.), my windshield fluid will not come out again, my drivers side door panel will put down my passenger window but won't put it up, my air conditioner is broken for the 3rd time, when you go to start it it dies - happening again, and now my transmission is going! It has been acting up for a while now. It seems to jump when press the gas & doesn't shift. I was driving to work today, up a very steep bridge and the car would shift. The rpm's went all the way to 5 and it started to make this sound. It wouldn't go over 20mph. I was very scared!! I hate this car!! I called GMC today & they told me there is nothing they can do for me, I am over the milage & I have no warranty.
  • I have been reading a lot of the post here on this forum and I am seeing so many problems with almost the exact same issue. I got in my Acadia one morning, started it fine, no issues prior to this, and began to drive it to the store. On the way to the store it shut off, no warning what-so-ever. I ended up getting it to a parking lot, all within 1/2 a mile of my house. It would not start at all, thinking it was the battery I tried to get it jumped, no luck. I checked everything I knew, coolant, oil, terminals even thinking maybe there was something blocking the charge. Nothing wrong. I had to have it towed to the nearest dealership, where after almost 2 weeks I find out that what the issue "supposedly" is, is that the engine has seized from metal shavings in the oil. Mind you it has just over 37,000 miles on it, and less than 3 years old. We only got our oil changed once through GMC due to the fact I am in the military and have been moved around a lot and some of the places did not have a GMC nearby. Sorry but I will not drive my car 40 miles to a dealer, wait half a day, just to have an oil change that I can get done closer to the house.

    Now after all that I do get called frequently by GMC Customer Service, that is not an issue mind you. But when I talked to them last I was informed that they would only pay for 40% of the cost.....that is almost $6000 as I was quoted by the dealership it would cost almost $10,000. Mind you, this is not acceptable, I don't have that much money lying around for something that my warranty should pay for. I did ask some questions to this, like if I had taken my Acadia to the dealership every single time that I had oil changed and what not, would that be covered then. I was told that they would cover 40%.....wait what???, not it would be covered then, no that they would only cover 40% even if I had taken it to the dealer to have services done there. Now that was aggravating, top that off, I asked if I did pay the $6000 out of pocket and did get it replaced, would my 100,000 mile warranty still be good, since it would be through GMC, or would it restart, or what?? I was told that the new Engine would have a 12 month, 12,000 mile warranty on it, and that is wait, you are telling me that even though this is a common issue, and it has been noted above by several different people, that even if it was replaced my warranty would basically become invalid, and that it would only go up to 12,000 now. What happens if after another 37,000 miles it seizes again?? I would be out $10,000 instead???? REALLY!?!?!??!?!

    Needless to say I had read what others have done and I am not going to be taking this lying down. Thankfully I do have a legal office on my base, and I will be talking with them in the next few days in regards to this matter. And if I am not able to get help through them, you better be d*** sure I will get an outside lawyer. If you are not going to honor your warranties when something like this happens, then don't offer them to people. I am tired of being bombarded with the notion that if you purchase this warranty then it will be covered, ummmm, no it wont as this has clearly been demonstrated.

    And before I am asked about this, my service request number is 71-1228966695. I was informed today that my case would be closed and that any further correspondence is to be done through the dealership as to help mitigate the time issues having three parties involved. While I understand that theory, I will have to get a new third party involved, and that will be JAG office/Lawyer.
  • Hey there! I am shocked that your dealer is not processing this through your PowerTran Warranty. Mine did! The whole job was covered. In addition, a week or two later my starter went as a result of the 'trauma' the engine suffered. That too was replaced free of charge. I purchased my car through this dealership and only have good things to say about them (so far). Sad to hear that your dealership is trying to rip you off.

    This seems too common an issue with this vehicle after 30k miles. GMC should really recall them. They are nice looking and roomy but not dependable or safe. My engine seized on the highway and my teenage Son was driving. I can't tell you how thankful I am that he was near the exit to our home. Thankfully.

    I would definitely hire a lawyer. Keep us posted.
  • That is not totally the case, the dealership is working with me on this issue. This is the GMC Customer Service that is telling us the 40%, we are currently though trying to get all the paperwork together on the oil changes. Maybe once they are all together then the dealership can help us out more, but it has been two weeks that my wife has been without a vehicle. If they, GMC C/S still insist on the 40% then the lawyer will get involved and to top that off we will also be getting the lawyer to get us the months payment out of this too......sorry but we are paying ALOT to not be using it.

    Hopefully the Dealership can help us out. Mind you any amount I have to pay will piss me off, but something under a 1000 is more plausible than 6000. Will keep everyone posted though.
  • I have had this same experience with my Acadia, and it is currently in the shop with an estimated (out the door) fix price of $3684.00!
  • I have had my 2010 GMC Acadia for almost 3 years. I currently have 104,000+ miles on it. I recently took it to the dealership and was told that the whole engine needed to be taken out so they further examine the engine and find out what exactly the problem was.
    Come to find out I need new bushings on the steering, and I need to have the cham shafts replaced. right now I am looking at a $3,684 from the dealership.
    I'm so upset that this has happened, and I will never buy a GMC again.

    I'm having the same sludge issue with my '09 Acadia but am being told GM will not help because I'm past my warranty period (118K miles). I'm wondering if any of you have considered a class action lawsuit against GM? I'm not sure what it takes but will be seeking an attorney for my own personal situation. In light of all the recent findings with GM that they have been very negligent with many of their vehicle models.
  • I have had the same engine problems and sludge issues as all the rest and am
    starting the process of a class action suit for anyone who would be interested I joining me. I have several media outlets willing to cover the story. 
  • Do not, do not, do not buy an Acadia!!! GMC will not honor their warranty! I have an 08 that needed a new engine and they told me the acid levels in my oil were too high!?!?!? Acid levels? I couldn't get anyone to explain what that meant. The engines in the 07 and 08 were not good engines and gmc had a lot of problems, more than they wanted to fix obviously! 
  • Bought a new 2011 GMC Acadia with a 100,000 mile / 5 year power train warranty. After 60,000 miles / 1,840 days (5 years + 15 days) we experienced a "catastrophic engine failure". First told by GMC to be patient while they gather data requesting assistance. Originally told $0 assistance due to improper maintenance, we then provided copies of our maintenance records. We were told the oil filters were not AC Delco filters and were told by a GM Service Manager that this caused the problems and this states this in our owner's manual. We pointed out in the manual it states or equivalent. The Chevy dealer then said GMC would split the cost 60/40 for a new engine. We did not accept this offer since our vehicle is less than 1% outside the time frame but still well within the mileage frame. We countered GMC pay 100% for new engine or buy our vehicle back at fair market value before the engine failed. After 3 weeks of being patient, the Chevy dealer recommends to have the vehicle towed 22 miles to a GMC dealer. My patients are wearing thin, I believe this is GMC's plan.

    What oil and filter were you using when servicing the engine? Specifics are important, if you can provide them. What was the mileage and time interval for the services?
