GMC Acadia Problems and Repairs



  • Are these recalls on the 2007 or the 2008 Acadia?
  • Well the dealer finally what appears to be the problem with the anti lock brakes stability control ect on my wifes Acadia.

    Those numb nuts in the manufacturing plant routed the wiring past a sharp rivet which pierced the wiring harness and caused it to short out. The tech repaired the shot and rerouted the wiring.

    Hope this fixes the problem and helps others with a similar issue.

    Still considering getting rid of this problematic thing and writing a letter to GMC's engineering group.
  • I am very displeased with this vehicle and with Gm..Here it is October and I bought the vehicle with 50 miles on it and I have less than 4000 on it now and my power steering pump is leaking fluid like it is going out of style..The Acadia is parked under my carport and has been since the weekend before October 15th. I have been waiting on a Power Steering pump now for going on 2 weeks..I talked with Gm directly and basically was told that I am going to have to wait for them to get the power steering pump in to the GM factory and then to the Dealership where I bought the vehicle from..Said they have a certain amount that is being shipped an so many people are needing one..So in the meantime I have to ride my family of 5 around in a 4 door car with 2 in car seats and one 6 year old in the middle of the 2 car seats and pray that I don't have a wreck and kill the 6 yr old pinned in between 2 car seats..Told GM I needed a loaner vehicle because the power steering fluid was ruining the undercarriage of my brand new vehicle. And that was the reason I wasn't driving it..After the dealership and GM told me YOU can drive it It won't hurt anything..SURE it won't hurt anything JUST the resell value when I go to sell this piece and the buyer asks me Hey what is all that oil under the undercarriage of your 4000 mile new vehicle.?? So the Acadia needless to say hasn't been driven in 2 weeks...ALSO Have any of you did this software upgrade for this Acadia. The one dealing with the transmission?? I read where they said it will effect the gas mileage for the first couple of weeks..My question is what is gonna happen in 2 weeks that will make my gas mileage go back to normal??? I ain't fallin for that one..Sounds like a bunch of poo poo to me>..Let me know if it helps or hurts to get the upgraded tranny software...Thanks for letting me rant and rave...
  • Well now the AC doesn't work and the outside temp sensor is frozen at 37 degrees and it is in the mid 70's here in Colorado.

    Not sure if this has anything to do with the short in the wiring harness and the fact that they failed to rehook up the AC or what.

    Have read other posts about the outside temp sensor.

    It's anyone guess as to what is going to happen next.
  • I just wanted to let everyone know that I just had to have my whole Transmission replaced in my 2008 Acadia and it only has 2900 miles on it. And the service department is still not really sure if that will fix the problem.
  • Looks like our 2008 has a major transmission issue as well. My wife heard a loud bang when shifting into drive, then the car, which has 3,500 miles on it, wouldn't budge. Had it towed to the local dealer on 10-17-07. Ten days later, and they still haven't figured out the cause. Can they go any slower???
  • Hello everyone,

    I just bought a GMC Acadia here in Texas and was thinking about years of non-problematic driving but that doesn't seem to be the case. I've had the car less than 2 weeks and less than 1000 miles, and the anti-lock brake system started engaging at very slow speeds in parking lots for no reason. Also the a/c wouldn't stop pushing out cold air and I had it up to 88 and a/c off, what the ....? I had to turn the air off and then auto to get it to work.

    Now I'm worried that the transmission or something else might give out from reading here. What are my rights people? Can I 100% turn this car in and get my money back? I do NOT want a problem car!!! I'm use to driving Acura, Honda, and Lexus with no problems. I only bought this because my wife liked it. I'm going to bring the car in next Monday. I would like to give it back, do I need a lawyer? because I am NOT taking this car. I also used a trade in, what a mess!

    Also the car never had much get up and go but I notice more now that it doesn't have the pony up to really move. I can see the problem that others talked about catching up with me. I think they mated the engine to the trans very poorly and that's just great.

    I want to go back the comfort of the best auto makers in the world forget going anywhere else again. Listen to me folks, this is not normal, cars should not have any problems from drive off, if it does it's junk. I don't care if it's a 100k Mercedes or what. We don't pay alot of money for troubles less than 5k miles. This is fraud!

    Please help! What can I do?
  • I felt the exact same way. I told them I wanted a new car or my money back and was told that my name was on the title it was now my car. We have checked into the Lemon Laws here in TN and the car has to break down three times without them being able to fix it. Supposedly the are trying to say that maybe it was just a bad batch of cars or something. We have even talked with the GM Company and the owner of the dealership that we bought the car at. So if you figure out what we could do please let me know. I'm so scared driving around in that car with my kids in it. I don't even like to have to pull out of somewhere I'm afraid that it is just going to stop again.
  • Yeah they could not ever find out what was actually wrong with my transmission that is why they just put in a brand new one. They are sending it back to GM to have it analyzed to find out what was wrong with it. THe Regional manager over the service center came down and could not figure out what was wrong with it so good luck.
  • Hello Again, On my 2007 SLT 1 Acadia.
    I have already complained about my problems earlier. Still very, very, dissapointed in the gas mileage.Still only getting about 16.9 on average - BOTH CITY AND ROAD COMBINED.
    They advertised on the sticker window - 18 city - 26 road.
    I don't know where they tested the vehicle to come up with that mileage or how they done it ??? Seems to me that they are putting out some FALSE ADVERTISEMENT?
    My advise to anybody - IF YOU WANT A SIMULAR VEHICLE - CHECK OUT THE 2008 TOYOTA HIGHLANDER LIMITED.They built it bigger this year. I'm trying to trade this Acadia for one.
  • My 2007 Acadia was leaking water inside on the front passenger side where the seat belt pulls thru & on the floor under the glove bos. The dealership says they have found the source of the leak (on the 4th try). A drain hose was not connected -- as in never was connected -- near the rear sunroof. They think they have it fixed now, they had to drop the headliner (that worries me) along with the DVD system, air vents (worries me, too!). Should get the car back sometime today, so we'll see. Other than the leaking issue, I've not had any other problems with the Acadia -- really love the car!!

    I'm sure the 1 mpg difference between the city rating and what you are getting is reason enough to lose thousands of dollars to get rid of it. I drive mine a 75% city 25% highway split and get about 17-19 mpg on average. When I took it on a long highway trip with it filled to the gills, I still got 24-25 mpg.

    BTW: Did you happen to notice the size of the vehicle before you got it? Did you happen to notice that it was about the size of a minivan? Did you expect to get 30 mpg in a 7 passenger non-hybrid vehicle? If so, you need to wake up. I'm sure with the increased size of the Toyota, mpg will suffer. It is the nature of things. Bigger and heavier things get worse mpg than smaller and lighter unless you throw hybrid in the mix.

    Reason #257 why I don't like sunroofs.
  • Got the Acadia back on 11/1/07 after more than 2 weeks in the shop. The diagnosis was a broken transmission gear...actual pieces of metal that broke free and jammed up the transmission...on a nearly new car??? hmmmmmmm

    Anyway, also had the trans flash performed and I've got to say the car shifts much more smoothly and the noticable downshifting/trying to find the right gear when accelerating from a 40-60mph cruising spped is gone...keeping my fingers crossed!!!

    . . . nothing worse than a brand new vehicle that's a pain. . . .but all things considered, this thread is relatively small on serious complaints. I'd love to see GM return to making at least it's share of the best cars in the world. We all need to pull for our American auto makers. It appears GM and Ford have gotten the message and are making serious efforts. I hope this Acadia is a world beater, and in spite of the complaints, I'm considering one.
  • chuckhoychuckhoy Posts: 420
    When the topic of the thread is "problems and complaints" that is what I would expect to get a lot of. Every auto maker makes some lemons. Every one. I have an 07 Outlook and so far my biggest complaint is that the outside temp sensor does not work as well as I would hope. In the grand scheme of things, it is a petty complaint.
  • why don't they just take one off another car that's what they with my 07 AWD. The power steering pump is bad. You need to call the GM number in the back of the book and you will get a rental car. My Acadia stayed 28 days and we had a rental... Good luck, Goodbye GM I am going to trade it before I get stranded on the side of the road in nowhere land.
  • I had the same problem in the first week after purchasing my 08 Acadia back in August. I was parked in a parking space and when I put the car in reverse it was like the transmission wouln'dt respond at all. I then put it in drive since I had rolled partway out of the space, it wouln'dt go forward either. I finally let it roll out of the space (it was on an incline) so I could get it out of the 10 min. only parking, after several attempts to rty to get in drive gear it lunged forward and died. I was able to restart but needed it towed to the dealship, who initially told me that the car ran fine. Later they called to say it was a computer problem with the transmission, the same problem they are addressing in the recall.
    Now, besides other small problems, I'm still having the same issue that others on the board are have with the vehical shifting. Getting unto a freeway is always an experience, most cases when you push on the excelerator the car slows down, push the pedal harder and it will eventually kick in and accelerate.
    This is my first American car in 15 years, I'm beginning to wonder if I made the right decision.
    Total days in the shop since purchase, 8, mpg. 14.5. Most of that was waiting for the nav. system to be installed

    I have a 2008 SLT2 AWD Acadia - the service stabilitrack and traction control warning light keeps on coming on. I have had it serviced two times and the dealer only clears the code for the warning. They cannot find a solution yet. Has anyone else experienced this problem and was a solution found? Thanks for the info.
  • Had the same problem. With the Stabilitrack light and warning message coming on.

    Took the dealrship two full weeks to locate the problem.

    The numb nuts at the factory that assembled the vehicle routed the cabling for the wheel sensor that sends messages to the computer that regulates the stabilitrack programming for the vehicle over a sharp part of the chassis under the right rear seat causing a short so that eeverytime the cable moved the message and warning lights came on.

    The dealship technician re-routed the cable and added some shrink wrap tubing over the cabilig to protect it.

    The dealership in trying to locate the problem had practically rebuilt the entire braking system before they found the problem.

    So much for GM's great quality control.

    These problems on the Acadia's must be costng them a bloody fortune.

    No wonder they are billions in the whole.

    Thanks for the info - will keep it, if it turns on again.
  • Very unfortunate..

    I understand your frustration - but here's my honest understanding - (and I am not an attorney) is that there is a very high bar for your car to be declared a lemon - so even if you hire a top $ attorney - you may end up spending more money that way.. You are better off living with it for some time - and trading it in for another vehicle..

    Look at these links - &

    I was planning on buying the 2008 Acadia and after reading your post, it is giving me a serious pause..
  • I bought a 2008 Acadia 10 days ago, yep - that's 10 days, and it broke down. The car would barely move in drive or reverse and the stability control system light is flashing as well. After a tow, the dealer has no idea what is wrong with the transmission or the stability control. I saw in a previous post where it mention the wires needed rerouting, I will suggest that. I am regretting this buy already. I chose between the 4Runner and the Acadia. I should have gotten the 4Runner. I had a GMC Sierra for 13 years. It gave me transmission issues at the 11 year mark. I should have learned from that one.

    GM - I am VERY disappointed! :mad:
  • You are giving bad infor on this one!!! I had a 2005 Pathfinder new after 1000 miles the fan belt pop I took it in to Nissan and they fixed it with another fan belt, well it pop again after 3500 miles and they fixed it again with another fan belt, well at 8500 miles it pop again I called 1800 my lemon in Philly showed them the 3 paper works for the 3 fan belts from Nissan and they took my case for free!!!! they called Nissan and Nissan offered to take the suv give me a loaner and give me $1,000 for my time till they fix the suv I told my lawyer I didn't want that I want my money back! so we went to court 3 day before court the belt pop again now we are at 13000 miles when the judge seen the 3 paper works for the fan belt he looked suprize but when I pulled out the 4th one we knew we won!! they had to give me all my money back for every payment even the down payment all I had to pay for was for 1000 miles I think it was about $900 I took that 5,000 and got a new MDX problem

    P.S. When I sent back the Patherfinder it had 15,800 miles on it!! just think if they would have took it back at the 1000 mile
  • I have a 08 SLT Acadia and the stabilitrack and traction control just went off yesterday afternoon and this morning while I was backing out of the garage but after a few minutes of driving the warning went away. Was going to take it to the dealer but I guess I'll wait till it comes back on. I've had a lemon (different make) before and hope that it doesn't get to that with this one.
  • Winter has arrived and I'm now getting to check out the AWD of my 2008 Acadia. After a 3" snow I though I would try it out on a driveway.

    My test: Stop on an incline, then resume up the incline.

    Results: Going forward, the all wheel drive worked as expected. As a wheel began to slip, other wheels began turning and I was able to drive up the incline just fine, slow and steady.

    Driving in reverse gear produced a different result. The right rear wheel would spin and the vehicle would not move. At about 3500rpm one or both of the front wheels kicked in, but the left rear still did not, causing the rear of the vehicle to begin sliding to the left, but still no movement up the incline.

    By the time the front wheels kicked in, the engine RPM was so high and the back right wheel was spinning so fast that any wheel turning was simply going too fast to get a grip. (My guess is that the front right wheel must have gotten some type of grip to cause the rear to slide to the left?) I never made it up the driveway while in reverse gear. We tried this test several times. Me thinks the TCM needs an adjustment.

    The service guys at my GMC dealer know of no tech bulletins out on this. I have it scheduled for service on 12/11/2007 -- I'll let you know the response I get.
  • My 2008 Acadia did this as well and required a re-flash of both the TCM and PCM. Pretty much everything is controlled by software these days.

    I called OnStar when the StabiliTrak and Traction Control messages came up in the DIC and asked them to run a diagnostic check. They said the codes they see are: 1) My ABS is not functioning, 2) the StabiliTrak is not functioning, and 3) there is a high-priority need for the PCM to be serviced within 24hrs. It's always a good idea to call OnStar (if you have it) to get the codes documented -- in case they mysteriously go away before you get it back to the dealer.

    After the 1st service, the error messages were resolved but the odometer began registering only 1/3 of the miles I was driving. I noticed this because my avg. MPG dropped to about 4.5. Took a while to figure out that the mileage was not accruing properly. Another trip to the dealer and a PCM update fixed that problem.

    it's cool if you have car in lease. Think 12 k per year, you can 36 k per year, after 3 years lease returm them with 100K on car, but odometer reads 36k.

    Now that -30C weather has arrived I was so pleased I had the remote start on my 2007 Acadia, then for 2 days recently it stopped working. Dealer informed me that GM already was aware that because of the Candian difference in gas mixtures (we have up to 10% ethanol) the fuel sensor notes "moisture" in the fuel so won't start, and thgat the gas guage reads errors too. When I looked at the guage my full tank read 1/2 full. GM is in process of rectifying the sensor to stand Canadian winters. On the other hand, I drove 1300 kms through 2 bad snowstorms in the last 4 weeks and traction was great, as was mileage.
  • My remote start also intermittently works. I can often see the lights flash when I press the LOCK button, but then pressing the start button results in "nothing". Sometimes I have to try several times. I wish I knew what is used for the antenna -- possibly I could park the thing a certain way so to get the best shot at it receiving the signal.

    Since you are in cold weather -- try this for me. Park on a snow-covered incline, headed down. Then put the vehicle into reverse and try to back up. I have found that one rear wheel spins, and the others don't, until I get to about 3500rpm, then the other wheels kick in. By this time, the one wheel is spinning so fast it has no traction at all. Does your Acadia do this?

    Then, try parking on the same incline, this time headed up. The AWD seems to work fine in this situation.
