GMC Acadia Transmission Problems



  • Hi

    I seriously feel cheated with The local Saudi agency UMA. They told me yesterday that they need another $3600 to repair the transmission problem time less than 6 months after the first identical repair.

    Is there something I can do. Can someone help
  • Sell the car. Don't have GM repair your transmission. Ask the new dealer to factor in the repair of the tranny on your Acadia and deduct it from your trade in value. They can repair it cheaper than $3600. You will take a hit on your trade in but it will be worth not dealing with the junk Acadia anymore. These Acadias are lemons and GM will not back their product up. They are crooks. I have an update to my posted experience but I am waiting till I get the car back to reveal it. You won't believe what they did to me. They ended up paying for the entire cost of the repairs to the tranny but there is a catch. Do not buy another GM. Stay tuned.

    in 2011 at 75K miles my transmission went out, total failure, while I was driving. The Chevy dealer rebuilt the transmission which was covered by warranty. But now in 2012 the transmission is failing again, called torque converter failed, and now it is not covered under warranty and they want me to replace the whole transmission $4500. Of course if GM would have replaced the transmission last year I would not have this problem, but they went cheap on the repairs and now I am stuck with this piece of junk and the bill.
    Advice to Acadia owners - trade in immediately upon transmission problems, because they will continue with this car. Also, please file a complaint with for safety of the transmission, and maybe we can all get a recall for this obvious problem that they will not acknowledge.
  • I wanted to update you all that I made the decision to trade in my Acadia. My GMC warranty was out, and although I had an extended warranty still in effect, I just wasn't up for the battle on the transmission. Not to mention all the problems I'm sure would come after that. I spoke to an individual today who owns a 2007 Acadia. I asked him about his car. He stated flatly that it was a piece of junk. He began naming the problems he's had with it. Not a coincidence they were the EXACT issues my car had. Struts had to be replaced, power steering was repaired (although, not satisfactory), transmission had to be replaced after warranty went out which cost him $4000.
    I agree with the advice to be rid of the car. I bought a Honda Accord and I'm pleased as punch. Life is too short for these headaches. I will report the issues as suggested to put my signature on the line indicating GM needs to be accountable for these lemons. It's a shame we spend so much on a broke down piece of junk!
    I sincerely hope if you decide to keep this vehicle you get some recompense for your troubles!

  • Update.... for those of you just joining in, My 2007 Acadia tranny and 2010 Chevy Cobalt both went down on Nov. 11. Acadia transmission was spent with 68,000 miles about 7 months past warranty and my Cobalt with 84,000 miles engine blew with a cracked block (totally covered under warranty). I have details in previous posts so read those to catch up. After talking to GM customer service about my Acadia and sharing my displeasure about being out of warranty but many many many people having tranny trouble, my bill went from $3400 to $608.00. I was ok with this, however, when they put the new engine in my Cobalt, they severely damaged the transmission in the car and slapped a used one with 17,000 miles (so they say) in it. After arguing with the dealership about how they should have put a NEW tranny in the Cobalt and not a used one since they broke it, I finally settled for them taking care of the Acadia tranny bill and keeping the used Cobalt tranny. Although the dealer is a POS and did not offer me a courtesy car, or try to help me get my bill reduced, GM Customer Service was fantastic and if not for the lady there, I would have been fending for myself. So I encourage you all to call 866-790-5600 and ask for Larra... she was wonderful and helped me out tremendously. She was the only bright spot representing GM. I traded the Acadia in the next day for a Kia Sorento and couldn't be happier.

    I bought a 2007 GMC Acadia SLT [White] in 2007. I was very content with this vehicle until my guarantee expired six months ago. Around this time, I started having problems with the car; specifically with the transmission. I went to the dealer and he told me I was not covered and that the repair would cost me between $2,000 and $3,000, an amount that I cannot afford to pay (I still owe $9,000 on my car). Four months ago, I began to experience issues with the AC, specifically with the blower, which cost $350 to repair. Today, I went to Firestone in order to fix the car, they told me I had several problems (SU9491 MAP SENSOR, MAF SENSOR, FUEL SYSTEM, etc.), these repairs cost $892.34, but Firestone told me that they do not repair the transmission or the traction control, therefore these problems have not been fixed.

    I’m very careful and meticulous when it comes to my car, I maintain it regularly, it looks brand new. This is my third GMC vehicle. I previously had an Envoy and other GMC vehicles and I had no complaints with these cars. The Acadia is not a cheap car, and I expected a higher quality car for what I paid. I am very, very, very disappointed and frustrated with how my current car functions, and the mechanical and electrical aspects of the car. I am a person belonging to the middle-class, my wife lost her job, and I cannot afford this necessary repair. I never thought that a car this new could have so many problems, especially problems with the transmission. I am very loyal person, but I’m planning to get rid of this car as soon as possible and I will not be buying another GMC vehicle ever again and I will warn everyone against buying a vehicle from this brand. It’s a shame, because I liked this brand, I like that this is an American-Made car, but the quality is questionable.

    If there's anything anyone can do to help me, please let me know! Thank you.
  • Talk to your dealer or call customer service. It will take a few weeks but don't take no for an answer. They are aware of the problems, especially the transmission. I was also out of warranty but got them to agree to split the repairs 50/50. DO NOT PAY UPFRONT! Good luck!
  • Like I said in a couple posts above yours... call GMC Customer Service. My Acadia had 68000 miles and 7 or 8 months out of warranty. I was assigned to a wonderful lady named Larra and she got my bill from $3400 down to $600. I ended up not paying anything because I also had a Chevy in there getting an engine replaced under warranty and they ruined the transmission in that car in the process. I got the Acadia back last week and the AC is not working and my power steering is whining horribly. I just bought a Brand new 2013 Kia Sorento SX AWD which is their top trim line and every option available for about $31,200. 5/60,000 mile bumper to bumper and 10/100,000 mile power train (engine, drive shaft and tranny) warranty. I was surprised by the quality of the Kia. Although it is a little smaller than the Acadia, it does have seating for 7 passengers with very little cargo space, or fold last row of seats down for 5 passengers and plenty of cargo space. I got well over KBB on the Acadia which held its value quite well. So get rid of the damn thing now while it's worth something. Good Luck.

  • Well I also have gotten the news that my 2007 GMC Acadia needs a new transmission due to bad wave plates. Our warranty expired in May and we have 103,000 miles on it, so also not too far out of warranty like many others on this site. After reading this blog, I was sure that nothing good could happen from this. However, to my surprise, my dealer just called me back and is offering a deal to us through GMC to put in a new transmission and fix the AC issues (also seem to be a common thread) for $2600! I am considering myself very lucky because we can't afford a car payment right now, so although I agree this car seems to be a lemon I am going to fix it. I'll report back later on how it is running.

    Looking forward to an update, hawkfan92!

  • I did but after a 20minutes overseas phone call I was asked to call another call customer center but in the UAE since our car VIN doesn't show up. Oh well
  • Just an update. An update on our sorry situation. We received a call from our local agency to come and pick up the finished car. When we tried to test the car it turned out to have a very loud sound coming from the transmission system section. I I have no idea why they did not test or notice it before calling us. A mechanic took a look at it. And determined that the transmission needs to be rebuilt (for the third time in less than 5 months)!!.

    In conclusion: we almost paid another $3700 for absolutely nothing.. Like the first time

    On the plus side they gave us a very basic Aveo until they finish the Acadia this time For our truble
  • I now get to be part of the fun! Only 55k miles and the transmission is toast...and only 7 months after the warranty expires!

    The quote is $4,200+ from the dealer.

    Seems like this is a common issue. Are folks getting support from GM or am I on my own?

    Thanks for any responses.

  • I will never by another American car. I have an 2000 Toyota Avalon and a 2007 GMC Acadia.
    I have spent more money in 5 years on the Acadia and yet my Avalon in 13 years old. This car of course if out of warranty and has about 62K miles on it. Two weeks ago I spent close to $900.00 in repairs to have the Power Steering pump replaced, front brakes, and muffler. The tow truck just dropped off my car and the transmission is shot. I have pages and pages of service records of all the repairs and recalls that have been done to this car. We have been the dealership for years that we think there may be something wrong with the transmission but they said no. I see many posts from frustrated consumers with the same problems. Transmission and steering. I have also asked my dealership for the number to GMC but they tell me that they will only tell you to talk to the dealership. Can someone please tell me how much a transmission is going to be for this car? :lemon:
  • I would strongly recommend that you call GM and be persistent. We went thru the same thing and although the entire process took about 3 weeks,( and only 2 days of that were mechanical) it was worth it! GM agreed to pay anything over 1000$ for our new transmission. The downfall is if they pay for any of it we were told the warranty goes from 3yr/100,000 mile to a 1yr/12,ooo mile warranty. Stupid since it is the exact same transmission, but we figure it gives us time to wear the tires we bought 3 days before the transmission went out and look for a new, non-GM vehicle! I would also suggest filing a claim with the NHTSA. I was told by the NHTSA if they have enough complaints they will force a recall and then GM will have to reimburse us any out of pocket money for the transmission. It is ridiculous that they do not back-up their professional grade better than this, but it will never change if we, as a whole, don't voice our complaints!! Call GM everyday and take notes of who you talk to!
