    After reading the issues in this forum I have decided not buy a 2013 Acadia. I don't know who the person at gm is that decided they would follow up each post with a ridiculous response like "We're sorry to hear that you are having these with your Acadia. If we can check into anything further for you, please don't hesitate to contact us via email at (include your name and contact information, the last 8 digits of your VIN and mileage, and a summary of the situation).

    This shows a total disregard for the customer. If the customers were taken care of they would have logged onto the forum and posted updates to rave about how the problems were resolved. Since that is not evident, this diminishes the value of a gmc product and warranty. I will skip on this car as well as the Buick and Chevy versions.

    My name is Arik, I'm a US citizen living in Bergen County Nj and I will choose another option. I want to thank all those owners that took the time to post on this forum. You saved me thousands of dollars and hours of problems. My heart goes out to all of you. God bless you all and God bless America.

    I was so excited about buying an American car and the Acadia back in 2008. I loved the look of this car. I should of known something was up when all the things starting going wrong.
    It started with the leaking sunroof, that had to go in for repair multiple times due to a drain hose recall.
    There were a slew of other smaller, misc issues - that were professionally services from the GMC dealership - it was just time consuming to keep bringing the car in.
    The item that has broken my patriotic purchasing heart though came a few weeks ago when I was told that my timing cover seal is going bad when I went in for an oil change/maintence check.
    I was in shock. I have only 67,000 miles on this thing!! And I was out of my extended warranty by 17,000 miles!!
    Beside myself and disgusted. The seal should not be going this early in the game.

    I am told it will cost over 1k to fix. And of course... all I can think of as the other potential issues that will be coming to me from this car!!

    @misc23 - You are exactly correct. Here is the response that we received from the GM rep that asked for additional information.

    Hi mksip,

    I just wanted to contact you for a follow up. I did speak with a service advisor at Dale Wiley Automotive. The advisor was able to clarify the concerns that you are having. They are still certain that your vehicle is operating as designed. There are also no recalls or bulletins that describe the concerns you are having. You are still well within your vehicle warranty, so if anything comes up that requires repair, your warranty should cover it if deemed to be defective. If you have any other vehicle concerns please do not hesitate to contact me.

    So as you can see they just repeat what the dealerships have said. It is normal for a vehicle to roll back while in gear. If I had wanted a standard shift that I had to hold the brake and gas pedal at same time I would have bought a standard shift instead of an automatic transmission! Based on their comment I guess I need to wait until my warranty expires and something else to go wrong with the vehicle!

    My 2007 Acadia just started having transmission issues. I am taking mine to the mechanic Tuesday. The trans is slipping and making a whining noise when I slow down. I hope it's not the wave plate.
  • scottmay3scottmay3 Posts: 17
    Its the wave plate. Get your checkbook ready. Get ready for a therapy session as well and make sure your blood pressure prescription is current.

    it is at the shop now . shugging at around 35 mph :sick: . low rpm has 134K on it. Shop mechanic says he can't copy my issue?? really? Did you even drive it I asked?? they did a diagnostic test and all came back neg..No codes .. No codes are poping. idiot!!! They are going to flush it and see what happens... the mechanic also said that he does not believe it is the wave plate as it usually happens well before 134K. Does it really matter how many miles you have on your car? I live far from my place of work... :mad:

    i don't have a good feeling after reading all of these post....

    I did call GM Sunday and they laughed at me..
  • wthdidigetwthdidiget Posts: 5
    but they took my $$$ we drove it home and cuold still feel the issue! did he drive my car?
  • OMG this sounds EXACTLY the problems I had with TWO different GM dealers in Two different states! Both times the transmission left me sit and would not go into reverse one time, or forward the other time. The techs at the dealers said it needed a catalytic converter cause that's what the code on the computer dash thing told them. I may not know a lot about cars but I know when your transmission won't go into a gear, IT IS THE TRANSMISSION!! It had TWO new catalytic converters and it still ran like [non-permissible content removed]. WHen it totally left me sit on the interstate in Georgia, then the third GM dealer finally said oh it's your tranmission. I do not think the computer idiot lights will say it is the transmission - there is no idiot light for that. They only go by the idiot lights, not by what you tell them or how it drives. I HATE THEM ALL. GM strung me along for more than a month after I filed a written complaint online and told me their tech guys did NOTHING wrong! That's why I HATE GM and will NEVER buy another GM car and will tell everyone not to buy GM. They do NOT stand behind their vehicles and make crappy vehicles.

    Last week, my transmission started going. My 2007 Acadia had no pickup when starting. I was an hour from home, just me (a Mom) and my 3 kids. We sat at red lights while everyone went around us. Eventually we would start and things seemed ok once we got going. Then that problem turned into a different one. There was a "catch" between gears 2 and 3. We took it to be checked and guess what? It's the wave plate, which requires a new transmission! So I drove it tonight (hoping it would get me where I needed to go) and it left me along the road. I was driving and suddenly I could push the gas pedal all I wanted and my Acadia was just coasting. I think GMC should stand behind this issue and do a recall, but that doesn't look too likely based on what everyone else is saying. This is what we get for trying to buy US-made.
  • wthdidigetwthdidiget Posts: 5
    I am thankfull I have another car but it is an older car that has some things that need to be fixed.. but this ACADIA issue is really a ticker and I am not happy about it. .i just paid the damn thing off!!!!!! GM and the GMC Dealers need to help us and take care of us.. hell I don't have this kind of $$ sitting around and to keep forking out $$$$ because they keep saying oh it is this and it is that.. . bull crap .. RECALL THE PART DAM IT. :mad:
  • nboere1nboere1 Posts: 2
    You are smart... I made the worst mistake buying a gmc Acadia. Do not do it.. My 2008 with 57570 mileage hare the transmission blow on it and GMC are being assess about taken care of me.. I think all of us GMC Acadia owners need to file a class action lawsuit against the company.... I will never buy another GMA vehicle again!!!!!!!
  • nboere1nboere1 Posts: 2
    Gmc Acadia are a joke do not buy one.
  • wthdidigetwthdidiget Posts: 5
    My husband came home from Detroit MI last night.. and took my Acadia out for a test drive today and wooops it did it again. :blush: ... shugging and then it didn't do it again... not sure what the issue is with the car..... He is going to replace the plugs to see if that does anyting. We could be just throwing $$$ at it.. Who knows if it is the stupid wave plate.. But the mechanic does not seem to know what he is talking about either!!! :confuse:
  • If it is your transmission, get a rebuilt one - someone that knows how to rebuild them. PUtting another crappy new replacement GM transmission into it will probably not last long either. I hate my car. If it wasn't paid for, and I could afford it, I would trade it in a minute for a HONDA or a more reliable foreign car. Sorry but I am burned on US cars.

    I have a 2012 Acadia Denali with 21,00 miles that has a transmission with a mind of its own. When stopping at a light, the transmission doesn't always downshift. The engine will maintain 1000 to 1100 rpm's, then you will feel a jerk, transmission will downshift, and engine rpm's drop back to 600. Other times, when slowing down for a traffic light or stop sign, the transmission will downshift very hard, almost feels like someone hit you. Dealership has driven it, has been able to replicate the issue, but since there are no fault codes showing up, their attitude is that there is nothing wrong. This is the first and likely the last GMC product I will own if this is the best they can do building a product and then tell me nothing is wrong with it and that I just have to get used to it.
  • wthdidigetwthdidiget Posts: 5
    If it is the transmission and i am sure it is.... .. I will have someone else do it.. NOT GM.. That's for dam sure!!!

    Hi there,

    I am sorry to hear that you have been experiencing this issue with your Acadia. I know it can be frustrating when the dealer isn't able to pinpoint the problem. Have you tried working with a different dealership to get this issue resolved? A second opinion may be worth a shot. Please let me know if you need any further assistance with this matter.

    Amazing how I just went thru a similar experience. Vehicle lost power on highway, check engine light came on. The vehicle would not shift out of first gear. Took it to local GM dealer where we bought it in May 2007. The diagnosed it as a faulty transmission solenoid where the "ports" were clogged. I then commenced to ask questions how they would have become clogged as GM was the last one to have the transmission open, in July 2011 when they replaced a "faulty" backing plate. I asked could the port have been clogged as a result of not flushing the transmission when they last worked on it? "Possible, but doubtful...". GM's answer, "You are beyond the warranty, so it is your responsibility". Spoke to Alex, GM Customer Service. Explained to him the story, two days later another woman called stating GM cannot help as it is beyond the warranty. When asked about the possibility of contaminated il cogging the port, she stated, " I am not a technical person, I have to rely on the Service Writer". The same service Writer, Joe, who charged me for a front end alignment he could not find where I authorized it. My cost, "$1668.00" By the way lets not forget the timing chains replaced at less than 40K miles, or the fire in the front wiring harness, ( my portion of the repair was $300.00), or my cost for replacing the steering assembly, $900.00, because it is not part of the drive train??? Then the transmission in July 2011 which they stated, we will repair, as a "Good Faith", even through it was after I sent a tow truck to get it to have it repaired elsewhere.

    If you find a lawyer, please keep me informed as I too am looking.....
  • I have a 2007 Acadia which has had one problem after another, many of them MAJOR problems - transmission, timing chain, transmission control module. GMC Corporate informed me that they will not provide any assistance for my most recent $1300 issue - this after a long delay in returning my call, putting me on hold for an unacceptable amount of time, and no proof of the research that brought them to that decision. I am extremely disappointed in their lack of customer service and vow never to buy another GMC vehicle again. I am telling all of my friends and family the same.
  • emclaugh3emclaugh3 Posts: 1
    I experienced the same problem last week. Acadia went into neutral while on highway, driving 60 mph, then went into first and wouldn't shift out of first. We had transmission "re-built" at 62,000 miles, now at 83,000 the transmission needs to be replaced AGAIN. Our warranty just ended 4 months ago, so we were told new transmission would be $4000.

    If anyone finds a lawyer, please let me know!
  • sbellesbelle Posts: 2
    If your Acadia has less than 120K miles GMC is now (as of Nov.-Dec. 2012) footing the bill for the Stabilitrak issue under what they called an "extended warranty" (an 'act of good will' to keep them from getting their pants sued off for manufacturing these $35-40K lemons with cheap parts). And it is a major safety concern, so they should be held accountable (I lost all engine power while driving uphill in a 70 MPH zone on a busy interstate w/ my 2 kids in the backseat). The problem is actually a bad timing chain and not the transmission, though if not fixed can ultimately burn up the trans. I have an awesome mechanic who diagnosed the bad timing chain and did some research to find that GMC was covering it (just not publicizing it apparently as I had already spent hours searching and found nothing to indicate this). My husband called GMC Customer Service (not the dealer) and told them we'd taken it to the mechanic and when he told them what the engine codes were and the problems manifested from it, they totally changed their tone, from skeptical to extremely cooperative. They arranged for the GMC dealer of our choosing to replace the timing chains absolutely free of charge for us. GMC is also reimbursing those who had to pay out of pocket for the same, and I may be wrong but I think any other repairs related to the bad timing chain (i.e., transmission) and I believe it applies at least to 2007-08, maybe other year models, with <120K miles at the time repairs were done.
  • sbellesbelle Posts: 2
    BTW, if you look up recalls even by VIN#, it yields nothing about GMC's "warranty extension" or a recall on the timing chain. And strangely, we got a letter from GMC with the specifications I mentioned above only a few days after calling GMC Customer Service!
  • mbr549mbr549 Posts: 3
    Mine is a 2012 with 21K miles on it. Since there have been no fault codes recorded, GM is unwilling or unable to do anything about the problem. Add to the fact that the gas mileage is pathetic, less than 20mpg on the highway and about 16mpg with in town driving, I am less than enamoured with GM and their quality. To add insult to injury, someone claiming to be a representative of GM posted on my original post that I should take it to a different GM dealer to see if they could figure something out. My thought is that shouldn't all dealerships be staffed with competent and knowledgeable personnel who can diagnose and repair issues such as this. Right now, I'm leaning towards trading it for something else instead of putting up with GM and their lack of customer service.
  • mtlwizmtlwiz Posts: 6
    not defending gm, but to get 20mpg,with this small of a motor moving a 5000 pound vehicle is damn good! and it will cruise at 95 mph all day long.
  • dagger6dagger6 Posts: 14
    Here's the ironic thing. My 2008 Acadia was great - when it was working at all. Good mileage, great ride quality. But after two transmissions in the 79K miles I had it, leaving me stranded and in danger of getting steamrolled by oncoming traffic when the transmission puked for the second time, I couldn't take the chance. Got rid of it. GM Customer Service is the absolute worst. They lie. And when you show them proof that they lie, they lie about the lie. Just awful people. Nice to know we bailed them out and this is what they do with our money. Never again will I buy a GM product. This from a guy who bought his first of many Chevies in 1971.

    Hello mbr549,

    I completely understand the frustration you are experiencing with your vehicle situation. We depend on our dealerships to diagnose any vehicle concerns you may be having, and are confident in our technicians. Unfortunately, when the issue is unable to be recreated, we cannot determine the steps to advise towards correcting the problem. The option of visiting another dealership is solely for a second opinion, in hopes of them being able to find the cause of your concerns. Please let us know if you request any further assistance with this issue.

    Hey Amber N. Here's how you can help. OWN your problems. You guys designed this car. You built it. We PAID for it. And you made a profit. On top of which, you got OUR tax money to keep you afloat. FIX the problems you created. I kept my last vehicle going reliably for 344,000 miles before I sold it. It's still on the road with 375,000 miles on it. I maintain my cars to a fault. My Acadia was a disaster. No matter how well I took care of it, it FAILED. And FAILED again. And AGAIN. With 79,000 miles on it, I had to sell it just out of self preservation. It almost got me killed TWICE when the transmission died on the highway at highway speed. You FAILED FAILED FAILED to fix it.

    I just left my dealer that I was able to limp to in 1st gear. I'm thankful that the tranny went just before I turned onto the highway on ramp. I would live to hear from GM what solutions they suggest to this growing problem. My '08 is a few months past warranty and I anticipate that I will get the bad news tomorrow that I need a transmission I can't afford. With my wife out on maternity leave I think the dealer may have an acadia on their hands for awhile.
