GMC Acadia Transmission Problems



  • simbimbosimbimbo Posts: 4
    After reading more posts about the transmission failures and associated failed repair/rebuild attempts at various dealerships on this forum and on Edmunds forum, I began to worry that this repair would be the beginning of a long, drawn-out problem, so I called GM customer service to see if anyone there could help me. I was in contact with a regional specialist named Matt who told me he was going to contact the dealership to find out what was going on then get back to me; that was yesterday around 2pm. After 2 calls placed into him; I heard from him today, but there seems to be a huge disconnect between what he and I are discussing and what the dealer is doing, let me explain. Matt and I are discussing a new transmission for the car, but the dealer has no information on that from Matt, so whenever I talk to Matt, he tells me he is working on a new transmission, but when I talk to the dealer they keep telling me the rebuild is going great and I should have the car back soon… I'm really getting frustrated.

    Skip to yesterday afternoon....

    I received a call from Matt who was sorry to tell me that the GM rep responsible for my area worked with the dealer, and that the decision was made to rebuild the transmission instead of installing a new transmission because "It was in GM's best interest". I find this to be insulting.. with all of the issues I have had, I have been without this car for just under 3 weeks out of the past 6 months.

    Skip to this morning..

    The dealership called me to tell me the rebuild was going well, and the transmission was going into the car today and they were going to test it extensively before I would be able to pick it up. I told 3 service writers at the dealership that I hope they take the time to do things right because this car was going on a 500 mile trip this weekend including a run to the top of Mount Washington as part of my companies "Summer Outing". I told them unlike the other repairs they have made, on this one there is no option to "get it right the second time".

    I just would like to say, although the GM reps on this forum and on the phone are very polite, and the dealership is also very nice, I feel as if all of the posturing and attempts at helping me with this issue, from the initial failure, the camping weekend, new transmission, etc.. resulted in, well, nothing. I have received plenty of lip service, and promises to "look into it", but the fact is, I had to borrow a friends car for the camping weekend, and I'm still getting a dealer rebuilt transmission, so it was all for nothing. I'm very underwhelmed..

    I can only hope that the transmission is rebuilt correctly, and doesn't fail again.

    My dealer rebuilt transmission failed again within two weeks of getting it back. They ended up replacing it with a "GM Certified Rebuilt" transmission. I've had no further transmissions problems since then.

    I just called the dealership to find out what time I should pick up my car and I was informed that they are keeping it another day because now there is something wrong with the control section of the transmission and it gets stuck in 5th gear. This tells me that they didn't do a good job of cleaning all of the metal from the transmission and some found its way into the area with the control solenoids, etc...

    This really is beginning to piss me off. I knew this was going to be a problem. I just placed a call to Matt the GM Customer Service person for my area and demanded a new transmission and told him I don't want this one back.

    I'm beginning to wonder about the competency of this dealership, they may be nice, but they seem to need 2 or more tries to fix something. This may be the end of GM in my household.

    I need some help. I have a 2008 Acadia, loved it until it nearly killed my 4 year old and myself on a major highway in MA. Previous to what happened yesterday to us I had brought my Acadia to the dealer 3 x's to pretty much be told I was crazy because what I had experienced was not showing up on the computer when they checked it.
    The best way I can describe it is I will be driving on the highway and the transmission will slip into neutral and I can not get it to move. This has happened to me numerous times the most recent time is what worries me the most because I was going on vacation and driving with my child in the car....... and came to a dead stop in the middle of a major highway. I have also been experiencing my car bucking in reverse, again brought it to a GMC dealer and told nothing came up on the computer. This time after a couple of hours finally got it about 2 miles away to a GMC dealer. WHo had no time for me since it was close to 5:00 and they were in a rush to go home. They told me to leave the car and go on my way....... Again stranded 160 miles from home and not even an offer of a loaner or a rental. Seeing that I have brought it to GMC dealers and to be told it is fine worries me greatly. I know they will put it on the computer 2 days after it has been sitting there and it will be "fine" and how can they expect me to drive it 160 miles home. Called GMC yesterday and today and they seemed very concerned but not one person called me back today. Again I am stranded 160 miles from home. Seeing I almost died yesterday you would think GMC would be more accomodating than that.

    I do not feel safe driving this and need to know if anyone else has experienced this and if so what has been their sollution.

    Thanks- Stranded in MA thanks GMC for caring.......................

    Wow, sounds like I am not alone!!!!!!!! Our 2007 Acadia has 65,600 miles on it and was purchased on 7-9-07....just 5 years and 16 days ago. Just 16 days past the 5 year/100,000 mile warranty for the transmission ..........we were told today the transmission needs to be rebuilt.

    We were told by the dealership that we would have to use our Zurich warranty and that the only way GMC would pay for part of the repair was if, for some reason, Zurich denied the repair. We were also told that his repair could take up to two weeks.

    This car has really been unreliable and spent a lot of time in the shop. Here is a list of things that we have had go wrong:
    -Power steering unit went out after 2 years and had to be replaced. we were 500 miles form home.
    -Car started to leak water on the people sitting in the back seat. They did something to the drain tubes around our moon roof.
    -Heated washer fluid unit was recalled and fixed. When this fix did not work, GMC paid us $100 and completely removed the fuse on the heated washer fluid so it will never work again. They left an inoperable button on our dash.
    -Massive rattling in the front end. Several parts ins the front end had to be replaced.
    -Car died while sitting on 3 different occasions and had to be jumped. Nothing was left on. Dealership could find nothing wrong.
    -Now the transmission.
    -Problems that are inconsistent and not yet fixed: DVD player working inconsistently, heater/airconditioner "spits out" random hot or cold air when set to a specific temp.

    My wife loves this car but this will be our last GMC. Calling GMC customer is a huge waste of time and, on most occassions, have had a very difficult time communicating because the individual spoke very broken English.

    I would bring it to the dealer and insist they check for the 3,5,R wave plate failure.
  • lclanceylclancey Posts: 8
    Yes GMC customer service is a waste of time. Numerous people told me they would call me back of course no one did. The dealer is a joke no one has even called me from there and they have had my car for 3 years. Today I broke down and called GM executive in MI- I was in tears. I will let you knwo if I get anywhere with them. All I can say is I am going back to buying foreign for me we almost got killed because mine decided to stop moving in the middle of a highway- and NO ONE from GM cares at all. I will let you know if the corporate office is any better.

    I loved my 2008 GMC acadia .... but it has been at the dealership for 2 weeks now having the transmission rebuilt. It has 96, 000 miles and I was 300 miles from home when the trouble started. Apparently, after reading several post from this forum ... it is the 3,5, R wave plate failure. There are also 3 other acadias in this town that just had the same problem. This is so disappointing because I really liked this car but now feel it is not reliable and scared that this will happen again. I am suppose to get the car back tomorrow, but considering selling/trading .....too worried about being on the highway and not feeling safe!

    Thank you for taking the time to post your concerns. I would definitely recommend asking the dealer about the parts and labor warranty on the transmission. Please keep me updated on what you plan to do. I am happy to assist you in anyway possible. Please feel free to email me directly.

    I'm told yet again today that they just can't get the part fixed and running right. This is extremely frustrating and I don't know what to do. 15 days with no car - and at this point not sure when I will get it back. Very disappointed with GMC. Looking for a new car now .....
  • lclanceylclancey Posts: 8
    I am so afraid that is what is happening with me. I call the service dept. at the Gm dealer and no one is returning my callse is calling me back.

    I agree 100%... My tranmission went out with the same kind of problem over the weekend while my 17 year old son was driving, now the dealership wants to charge me 1500.00 just too look at it and then figure out how much more it will be to fix it... Really mine is all highway driving as well. I am just wondering why we even pay for extended warranty, because obvisously GM is telling us that any car over 100,00 miles does not last... I am not happy about this because its about the 6th thing Ive had done to the vehicle!!!! :mad:
  • rbahnsenrbahnsen Posts: 29
    Well here I am again... This is the third major thing that has happened to my 2007 Acadia..
    I am fed up, I fell that GM cars do not last past 100,000 miles which is ridiculious. I will never buy another GM car, I will buy Ford from now on.
    I had to have all new timing chains put on @ 103,000 miles, had to have my Service Tire sensor fixed at 112,000 miles, I have done all the re-calls for the sun-roof leak, the heated windshield fluid, and whatever else hs been re-called on this vehicle!!!
    My 17 year old son was driving my car in heavy traffic on a majoy highway when the car just stopped and then he could only get it to go 30 mph. He is lucky he was not rear ended. I took it to the dealer, it will not go over 30 mph and reverse. They told me they think it is the Wy plate and it will be at least $1500.00 just to get into the transmission and see what the problem really is.. Come on $1500.00??? Seems very high and then charge me for the parts and labor to get it all back together. I am soo mad and upset because I need my vehicle, so sice I am sure GM will not do anything to help with the cost I have to fix it just to trade it on a different vehicle because this one can not be trusted!!!! SAD SAD SAD that Gm cars wont last!!! Especially when I paid $40,000 for it 5 years ago. Thanks GM for nothing!!! :mad:
  • After this happened to me I made a call to GM executive in Detroit. I keep telling them they need to look into this problem because it is not only happening to me and it is a major safety concern. But they DO NOT care the women is like oh ok I will call you on Friday. Really GM! I wish there was something we could do to get them to listen. When and if I get my car back I will be getting rid of it, which sucks because I still owe a lot of money on it but if I have to take the loss I will just to be safe. :lemon:

    Unfortunately, to "check" the wave plate the entire engine/trans/suspension/steering assembly needs to be dropped from the vehicle in order to access the side cover of the trans which needs to be removed to access the 3-5-r clutch and wave plate. Some techs will try and do this without dropping the whole thing from the vehicle and are successful, sometimes. However, if it isn't the wave plate it still has to be put back together again. If it has no reverse or grinds or bumps in reverse, chances are extremely high it is a wave plate issue. Usually there is a code stored as well. Typically something about shaft speed sensor error. Thankfully, none of the wave plate repairs I've been a part of or witness too have ever come back with a repeat failure. That is, as long as the trans was completely disassembled and all the metal wave plate "leavings" were cleaned out and a new filter installed.
  • One simple search and you should see the pages and pages of posts by gmc owners about their transmissions crapping out within months/days of the warranty expiring. One call to a local GMC dealer and they have three or four acadias in line in front of us that need transmissions fixed. When will GMC do something more than "check on the status of the rebuilds"?

    I have an '07 Acadia with 67k miles. My warranty expired March 02 of this year. So tomorrow will be five months out of warranty. Just this last Monday (two days ago), while driving to pick up my kids, Our sunroof leaking mobile decided that was all she wrote. She started skipping/catching while trying to shift and within minutes alarms were going off "Shut off Engine!", "Shut off A/C!", "Engine Overheated Shut off Engine!" I was able to coast into a local church as antifreeze began to pour (not drip mind you but pour) out from underneath. I shut off the truck, removed the keys, and opened the door and the alarms were still going off. I literally had to turn the vehicle back on and off three times to get the warning bells to shut up. I had to have the vehicle towed - the diagnosis was that I needed a new water pump and a new A/C belt. 450$ later .......I go to drive it this morning for the first time to work. I noticed it was still catching again but it only did it once. I made it safetly the whole 6 miles away that I work. When I get in it this afternoon to go pick up the kids the catching increased in frequency so I immediately turned around and went home. My husband drove it the 9 miles to the shop that had just replaced the water pump the day before and literally had to drive it in the emergency turn lane the whole way there because it refused to shift over third, and while trying to back out of our driveway; the reverse decided to crap out as well.
    A tech there informed us that it needs a new transmission; we called the local GM dealer and he is arranging to have it towed up there tomorrow to have it fixed ( the dealer is being more than helpful)....but will probably be 500$ out of pocket and a time frame of at least 3 weeks because he is so backed up with other transmission probs right now.

    So we are close to a grand out on this vehicle in less than three days for a problem that a large % of 07/08 Acadia owners seem to be having. I am also out of a vehicle for at least a month as well.

    Have any of you had any luck with recouping any of the $ that you've had to put out for any of these related issues?

    I have never owned a vehicle that has had so many recalls and problems! My husband and I are seriously considering getting it fixed and then trading it in for anything else but a GM product. However, even if we decide the keep the lemon, we will never buy another GM product again. GM's customer service would really have to come in and save the day on that one to make us want to change our minds. I was getting by with our duct tape fix on our unusable leaking sunroof - but this is beyond my level of patience.
  • 17 days and counting .... STILL do not have my car back .....and I still have no answers. This is ridiculus and I am very disappointed with GMC ... I think at this point a new transmission is the OBVIOUS answer. I just want the car back so I can get rid of it.

    If warranty is paying for the repair and a rebuild is $100 less than a new trans, you won't get the new trans. At least that's what I've seen so far unless management or GM step in. Still no guarantees though.
