GMC Acadia Transmission Problems



  • ok_acadiaok_acadia Posts: 3
    This is the first GM vehicle I have ever owned.

    My transmission just went out at 71,000. The water pump went out as a result of overheating due to the transmission issue. My warranty expired last month. Dealership has to rehaul the transmission. They've had my car for a week and a half already. Looking at $3,100 for the transmission and $500 for the water pump. This is after I had a steering issue that took over a week to fix. I noticed that day that the steering was having the issue all over again.

    After reading so many people having similar issues, it seems GM should consider some type of major recall on this vehicle. I had been considering purchasing their Terrain, but I doubt I will go with another GM vehicle. Despite all the recalls (which I have had done), I really loved this car up until the last year. I'm very disappointed.

    Dear All

    I bought a GMC Acadia 2008 when it was at about 70,000 KM, after a few thousand kilometers the transmission broke, I went through a transmission repair (complete overhaul) for about 2,500 US$. The workshop doing the repair gave a 6month/10K warranty.

    During the warranty, the link b/w the transmission and the engine leaked (red fluid), that was fixed within the warranty. Also have the vent/purge solenoid related emission issues, which I'm ignoring....

    Now I am at about 88,000 KM and the problem is starting to happen again, the reverse gear has started to become very unresponsive and gerky at times.

    I am really fed-up with this GMC Acadia transmission. Sami-ali has already posted his experience about this card in Saudi Arabia, so I don't know if someone will help me.

    I want to immediately sell this car if I have to get the transmission repaired again.

    CAUTION to buyers, THINK TWICE BEFORE YOU BUY an Acadia.....particularly in the Middle East where you won't get the full 100k coverage.

    This is really unfair from GMC, that they are continuing to ship this car without correcting the issue or doing a recall.

    I can see every one has had the same 2 issues - jerking while accelerating and freezing in one gear. I drive my 2007 Acadia in UAE. The jerking is caused by faulty engine mounting. The freezing in one gear is caused by overheating of the overspeed sensor. I observed that it happens after long low-speed trips around the city in hot weather.
    My 3 friends bought Acadias following me, and all three have sold them with huge smiles on their faces and switched to Toyotas. I have been luckier so far...

    Call GMC directly and ask to speak to the director of service. Tell them you feel that the vehicle is dangerous to drive express your concerns. As well look up lemon law in your state

    So, they've had my car for three weeks now. They rebuilt the transmission and my car was finally returned to me after two weeks. It ran fine going home that afternoon. On my way in to work the NEXT morning, I started having problems again. I took it back in. They pulled the transmission again. A week later, they tell me they can't find the problem so they are going to put in a whole new transmission.

    I'm trading this car as soon as I get it back. I didn't have any problems with it until the warranty ran out. This has been a nightmare, especially since I live and work outside of the city.

    So, now, they are saying because they had my car on the lift for so long, the struts went out and they had to order new ones to replace. Just another thing to be aware of, folks.

    So GM Customer Service, I just took my Acadia back in today, June 26, for - yes- the transmission AGAIN!! Same problem just as I predicted. It's been about 3 weeks since I got the car back.

    It seems the bean counters are dictating how cars are to be repaired. This is just mind boggling that GM refused again to install a new transmission after the second failure. I voiced all my concerns to the service people at Bill Deluca Chevrolet about the fact that they would not be able to get all dirt, metal shavings, etc out of the cooling system and transmission. Looks like I was right. The car is back in Bill Deluca Chevrolet (Haverhill MA). The car was bucking when it tried to shift. By the time I got it to the dealer it was stuck in 3rd gear and wouldn't shift at all.

    I want the Acadia fixed the right way now that it has failed THREE times now in 6 months. This means:

    New transmission
    New cooling lines
    New transmission cooler
    New Torque converter

    This is the ONLY way to keep this thing from failing again. I'll be done with GM forever if this doesn't get resolved the right way this time.

    The other thing to consider: GM has spent more $$ on labor & part rebuilding the transmission twice than it would have cost to replace it the first time as I had requested!

    I am unsure if you set up a Service Request through us as the incoming emails are generally answered by Christina. Please send us your case number or the last 8 digits of your VIN and we'll be sure to let your agent know of the situation.

    I sent an e-mail to the socialmedia address you gave in a previous reply. It contains all the information you had asked for.

    We have had nothing but trouble since the purchase of our "certified new" 2007 GMC Acadia last April. Twelve days after we bought it, it was in the shop for a shorted headlight and a squeaking noise in the steering column. It needed a new power steering rack assembly. Then, just 5 months later I needed new front and rear brakes. And that's when the water leaks started- in the front, in the middle, in the rear- at some points it felt like it was raining in my car! Between November and January (2011-2012) the car was at the dealership 5 times while the service department tried to identify the cause of the leak. It's finally been resolved, but who knows what type of damage the water did to the interior controls, electrical system, etc.

    Then it was in again in June for the front sway bar and brake rotors. The dealership tried to tell me I needed new brakes, but when I reminded them that I had just gotten new brakes in October- he "double checked" and then told me that "actually, they are fine." C'mon!!

    Now it is in again for the TRANSMISSION! At 54,000 miles and only two months out of the "certified used" warranty, the 3-5 wave plate broke, and apparently I need a complete transmission rebuild. So another 2 weeks with out my car. If I added up all the days I haven't been able to drive it because it's been in the shop, it would probably equal a month's time. Plus, we have spent over $700 (before the cost of rebuilding the transmission!) on maintaining this car- and it's only been out of warranty for two months!!

    I will NEVER purchase another GMC vehicle, and I will warn everyone who will listen that purchasing from this company is a mistake. With all of the transmission problems reported on this site, I am shocked that no one has brought a class action law suit against GM for this issue.
    It's a shame because I really love this car, when it's working. But I will never trust it again.

    Thank you for taking your time to post your concerns. Have you spoke with Customer Assistance regarding your concerns? Can you please email me with your VIN, current mileage, and involved dealer? I would like to look into this further for you. I look forward to your response.

  • I do have a case number but don't feel like the dealership is very concerned with fixing my car just giving me excuses. "If we paint where the molding don't have paint then the paint might not match the rest of the car because the diamond tri-coat is hard to match." "the car rolls back on inclines because the horse power isn't strong enough to keep the car from rolling back into who ever is behind you on the hill coming out of wal-mart, etc." So far we have had the wheel molding repainted because they were peeling within 4 months of getting car, the car was delivered to me after waiting 3+ weeks for the car to arrive with the door off track. The gear shift had to be completely replaced at 4 months because you had to force it down into gear, the chrome just peeled off the side of my car and scratched the door, the steering wheel was just replaced for squeaking when you turned, none of the door moldings had the paint completely to the edges. Sometimes it will die after starting but there is no way to figure that out unless it does it at the dealership, Sometimes it makes a loud whining noise but hasn't repeated it the last 2 weeks at the dealership. Sometimes when I'm driving down the road and I accelerate to pass it's like I'm in neutral and the car just whines instead of speeding up, then it will catch and then accelerate. I think the transmission is going out. I paid $50K for this piece of junk and I don't want it anymore. The lemon laws in Texas are 1 yr or warranty. Does that mean which ever comes first or what? We have had it 1 year this month and I have 14k on it. So disappointed in my "dream car"

    You could file a complaint online with the BBB to initiate a buyback or contact a lemon law attorney. As you know complaining gets no where fast especially at the dealership.

    So far I have had almost all of the issues listed on this forum

    Sunroof recall. Drop headliner and fix drain hoses
    Transmission shifting issues. Reprogram TCMA
    Stretched timing chains. Drop engine and replace
    Headlight burnout. Replace connectors
    Squeaky Drivers seat, seat moves. Replace seat mounting rails.
    Weird A/C control issues. Hard to control temperature. Reprogram control modules
    Steering noise. Replace steering hoses
    A/C makes hissing noise. Replace A/C hoses
    Brake pedal noise. Replace brake fluid
    Wheel bearing failure. Replace hub assembly
    Erratic shifting, no reverse. Waveplate failure. Rebuild transmission.

    The latest is the transmission failure, let me elaborate.

    Well, I was at the dealership. for a front wheel bearing failure and the tech and I took it for a ride.. While on a test drive the car experienced a very hard shift into 3rd gear. The tech took it into the bay and topped off the transmission fluid, took it for a ride and said it seemed better..

    I left the dealership and got on the on ramp to the highway and the car revved really high on a downhill ramp then banged into gear. I thought that was strange, so I continued on the highway. I then noticed some very erratic shifting and some more banging into gears, so I got off the highway. On the back roads I could hear a scraping noise in second gear and more hard shifting. I immediately called the dealership and told them I was heading right back, but may not make it.

    When I arrived I grabbed the tech and we started to go for a ride, but when he put it into reverse, it began bucking and grinding. We didn't even try to take the test ride because it was so bad.

    I'm sitting I the waiting room trying to figure out how I'm going to get a car that can tow my popup camper for our weekend camping/tubing trip.

    P.S. this was going to be the first time I towed with this car, it has the tow package, I thought maybe it would be immune to the 3,5,R waveplate failure, but I guess I was wrong.

    Once again, I can't tell you how happy I am with Vendetti Motors in Franklin, MA.... They have been extremely helpful with everything, but I'm becoming more and more concerned that this car may be a lemon. :lemon:

    I would really like someone from GM to help me make sure a NEW transmission is installed, not merely rebuilt.

    What year is your Acadia? Someone was having problems with their Mustang transmission over in Edmunds Answers and the OEM replacement looks to be a reman. I think that most replacement transmissions are remanufactured, not "new".

    Remanufactured is a lot different (in a good way) than a "rebuilt" transmission.
