Well gm strikes again. I just submitted a transmisson with my 2014 silverado but it looks like my 12 Acadia has the same transmission issue. We bought this Acadia used and within the first year of owning the transmission failed due to a known issue by gm. I almost got rear ended today because the transmission shuttered significantly enough that the car wouldnt go. I am extremely annoyed. I think its time we go to another manufacturer. . . The 35r clutch wave plate is junk and sends metal throughout trans and destroys it.

They said that time that they '' couldn't replicate the transmission problem it '' at a single test drive. Now that it has completely failed they say the extended warranty has expired time wise and they will not repair it. Despite knowing it is a safety problem freq.

Had my transmission fail while camping in the mountains with zero cell phone service. Check engine light came on at 121,657 miles, then deteriorated until it would no longer move when pressing on the gas pedal. Taken to the local dealer told me that the transmission needs complete replacement totalling 4. 5k. GMC refused to assist me in any manner towards the bill even though this is a very known issue with this make of vehicle. There needs to be a recall on these transmissions as it is a dealer defect.

The contact owns a 2007 GMC Acadia. The contact stated that the vehicle failed to accelerate when the accelerator pedal was applied numerous times. In addition, the transmission failed to function properly when shifting and various warning indicators illuminated. Within a week of owning the vehicle, it was taken to the dealer (shoreline auto group inc, 2275 n state rd, ionia, mi 48846, (616) 523-6882). The dealer kept the vehicle for over a month due to no sound for the turn signals, various warning indicators illuminated on the instrument panel, and the vehicle was slow to pick up speed. The dealer was unable to replicate and diagnose the failure for over a month. The vehicle was taken to an independent mechanic for further diagnostic testing. The manufacturer was notified of the failures months later to determine if they may be able to provide a solution to repair the vehicle. The approximate failure mileage was 14,000.

What's not wrong with this car?? I bought it used with an extended warranty. After a year everything went downhill. It has been in and out the GMC service at lease 3 times a year. I don't even know where to start. The airbag light is on but it isn't covered under the airbag recall. What about safety? there has been a check stability trac and traction lights on as well on several occasions. When those lights come on the vehicle decelerated while driving across the kentucky bridge which almost caused a 12 car pile up. In addition, it also skips gears. When trying to speed up it jerks into the next gear like a hiccup. The dealership stated these problems were electric and wear covered under my extended warranty. I suggested that maybe the transmission was bad. However, they stated otherwise. Literally, 4 months later the transmission is out. But what a surprise no longer under warranty. Now I'm looking at a $5,000 bill. The service department stated that it is transmission failure due to an electric issue (out of my control). There is nothing that I could have done to prevent it from happening. But after talking to gm they, basically explained that they don't stand by their product after 100,000 and that they can't prove that the issues are actually manufacturers defect. I strongly disagree as there are hundreds of people experiencing the same hardships as me with the 2008 vehicle. On carcomplaints. Com, for GMC Acadia, 2008 is the worst year with the most complaints for transmission failure. How aren't these already recalled by now? they are nothing but junk! not work anything. Even a GMC service rep. Said these were the worse year and get them in the shop all the time. Why won't GMC just isssue a recall and take them off the market. I have all the proof of regular maintenance and service receipts.

9/2014 at 93,000 miles transmission failed. Dealer confirmed GMC agreed to pay 60% of repair, but later after transmission, wave plate recall I was reimbursed. 2/2017 133,000 miles new replacement transmission is failing again in 3rd gear with same internal failure code per my service person.

Water pump failed in the freeway prematurely, brake cylinder failed prematurely, steering, rack and pinion and power steering pump failed @116k, transmission failed @ 116. No means of transportation with 3 kids.

1) a transmission switch plate error - warranty repair (GMC never paid my hotel/rental car claim. On hwy with family. 2) transmission issue - paid close to $2000. I asked if this would lead to transmission failure; they told me no, car would be good to go. The person who helped me no longer works at the el paso dealership when I reported he tried to overcharge me. Driving on hwy in el paso with kids. 3) transmission - paid $4000+ for transmission (GMC claims not related to the previous repair); discussed with service dept if we should spend more money on the car. . . They told me the new transmission would work. (mileage was 125k) the transmission failed while moving from el paso to colorado springs. . . No safe place to stop. 4) 2 mos later (now) - claim the timing belt failed and rh tie rods need repair and they say I declined a repair. I never discussed this needed repair and the possibility of a $2600 repair following this $4000 repair. . . So if they mentioned it, they never said you have $6600 worth of work in front of you. I already was concerned about paying $4000 after paying $2000. It happened on highway. GMC is more than aware of these issues with their cars and they are leaving their customers to deal with it. I have a 2002 GMC envoy and never paid anything close in repairs. There are serious problems with this make and model. We are also a military family who travels quite a bit. We started getting errors on road trips and we even had the original warranty repair while we were out of town, causing us to be stranded on the side of the highway in the washington DC area when our car just stopped. GMC is showing a total disregard for its customers. They are aware of these issues and they are not taking any responsibility for them. They are putting their customers in physical danger and wreaking havoc on our finances. This is disgusting and unacceptable.

The transmission went out. I only have 70k miles on the car and we had to replace the entire transmission. It cost me several thousand dollars to get it fixed! I am thankful that when it happened, my husband was pulling into a parking lot and not going down a freeway with our children in the car. As I investigate this issue with the 2007 Acadia's I'm finding that the transmission failure is a huge issue! please GMC fix this problem before lives are lost.

Steering locks up when driving down the road causing you to lose all control of your vehicles steering. We almost hit traffic light and hit by a semi on the interstate. Also transmission failed and will loose all power when your driving down the road. This vehicle is dangerous to drive and is a very common problem. This needs to be recalled or a class action lawsuit needs to be opened. This vehicle only has 88,000 miles on it and is a hazard to drive.

I'm logging these issue as I have now come to realize that the issues we have had with our 2008 GMC Acadia are very widespread among owners. Very early on in the life of the vehicle approx oct 2008 we began seeing small amounts of water inside the cabin. Water would drip along the windshield occasionally, no action was taken as it was not consistent or so we thought. On multiple occasions my wife would complain that the vehicle would "cutoff" or "die" generally at slow speed in areas such a parking lots when turning, however the dealer was unable to re-create the issue so no repairs were made. One day this summer (2014) my wife was unable to start the vehicle, it just would not crank. On taking it to the dealer the vehicle was diagnosed with a corroded battery cable that ran from the middle of the vehicle to the starter in the engine bay. Cost to repair $1,200. In approximately June 2014 the vehicle began experiencing a slight rollback when placed into drive. At first we didn't think it was an issue as it didn't get worse with time. However by October 2014 we got a check engine light, diagnosis transmission failure cost to repair $4,890 after a $200 discount.

2 months after I bought my vehicle used I have had to replace ignitions coils, so many recalls and only had some replaced cuz of being told they don't have the part in store at the dealerships. The electrical system for heat and a/c don't match up when turning the knob and the defrost doesn't work 3/4 of the times. I get flashes of loss power and my tire monitoring system keeps acting up. Now my engine and transmission are failing and no one can tell me exactly what it is without paying $5000 for them to diagnostic it and take it apart!! where do I have that kind of money?? this vehicle was the worst $16000 I have ever invested in and have only had it less that 2 years!! I am scared on a daily basis to drive my kids anywhere in it let alone myself to work. I so wish I would've kept my Jeep grand cherokee but we need more room for travel. Well you can't travel in something that's unsafe and unreliable. GMC won't call or respond back and either will the dealership. Lemon law in michigan is for new vehicles only so I am basically paying for something I can't drive and I can't afford to fix. What do I do??.

Vehicle transmission failed. Wave plate destructed ruining transmission. No warning. Traffic behind was forced to slam on brakes and swerve. Caused traffic jam. Very dangerous. Known manufacturing defect by gm. Refuse to recall. Hundreds of complaints that have the 6t70/75 transmission (enclave, Saturn, some fords).

Transmission failure @ 67070 miles. 35r wave plate. GMC dealer service rep. Said they had never heard of this problem. Personally talked to dealer mechanic, and he states that he has replace a number of these transmissions for wave plate failure. It's bad enough that this is a know problem and gm does nothing about it, but for the dealership to lie to me right off the bat, takes the cake. No more gm products for me, ever. . . . .

The contact owns a 2009 GMC Acadia. The contact stated while driving 70 mph, the vehicle stalled and the check engine light illuminated. The vehicle was taken to the dealer. The technician diagnosed that the transmission failed and need to be replaced. The manufacturer was not made aware of the failure. The vehicle was repaired.

My wife was driving home from work when she experienced erratic operation of her vehicle. When taking off at first the vehicle lacked power then suddenly the engine rpm raced and the vehicle lurched forward. The engine speed was uncontrollable with the throttle. At a stop light the vehicle would barely take off and suddenly engine rpm's would race and the vehicle would surge when throttle was applied. The vehicle was driven directly to the GMC dealership on the way home and at that point it was determined the reverse gear was completely inoperative. The transmission failed due to a broken reverse wave plate. Vehicle was delivered new 7/10/09 (less than 5 years). The transmission replacement final billing was $3,906. 54.

Transmission failure. 2007 was the first year of the GMC Acadia. At 94,000 miles I don't think the transmission should fail. When I purchased the car it came with a 5 year 100,000 mile power train warranty. I have owned the car for 7 years. I know GMC has made improvements to later models. I feel this is a huge injustice. I have been quoted $4500. 00 to replace the transmission by the dealer. I have been told by a reputable aamco shop that the only place this can be fixed is at the dealer because they have the codes to make the transmission and engine work together.

Transmission failure while traveling on interstate. Only to find out this is only one of multiple Acadias with this few miles to have this happen and leave us stranded miles from home. And unfortunately we are now finding out that a lot of people have had this happen but noone bothered to tell us about it or warn us that this might be a problem. And of course our warranty has expired because we have owned it 5 years and have taken very good care of our vehicle having the oil changed every 3000 miles and tires rotated and balanced routinely and you could look at it and it looks brand new. . But now we are out $4000. 00 + which should not be happening with this vehicle. . We are very disappointed and angry that we could have been in a very dangerous situation had my husband not been the one driving that day.

I was driving home when my transmission suddenly started to lurch and hunt for gears, then hesitate. My car then wouldn't move forward nor would it go into reverse. Two codes showed up when I had the vehicle scanned, p2715 and p0700. After doing research I concluded the wave plate in my transmission had failed. My vehicle is no longer drivable. Thankfully I wasn't on the freeway when this incident happened because once the transmission quit the vehicle came to a stop rather quickly. In reading reports online it appears transmission failure of this particular model is highly probable and that gm knows it's an issue but has refused to recall the vehicle.

I just had my transmission fail on me yesterday. Luckily it still had 1st & 2nd gear, unfortunately I'm 5yr-8months into it at 58xxx miles. Sounds like I'll be paying for this one. If there is any info out there on recalls . From what I've been reading online, it seems there is a real problem with this transmission (6t70) in the early years. I imagine as more and more '07 - '09 Acadias (traverse, enclaves & vues) get into the 50k+ mile range the transmission problems are really going to start spiking up. It would be a real shame if gm chooses to ignore the obvious and push this problem back on to their customers.

I was turning left at stop light. The transmission failed to shift and stalled causing me to be struck. This could have been a fatality if traffic were heavier. I have since researched and found that gm has had thousands of complaints regarding the transmission problems. This could have been prevented had gm recalled a defective valve located in the side box (according to mechanic at gm dealer this is why I stalled out). I am seeking an attorney for a class action lawsuit.

Wave plate transmission failure 2 months after purchase and 5 months after warranty. So disgusted!!!.

We bought vehicle from hendrick Toyota on 6/15/2013. My wife began driving to work when it completely stopped in the middle of the road. She was frantic because of the busy street and thankfully, our kids were not in the vehicle. Car was towed to hendrick where it was determined that transmission failed. It was told to me that the wave plate in these vehicles was known to fail and after research and a technicians affirmation, apparently GMC never tempered this particular part and have known about the issue for quite some time. Again, after researching, I've seen countless complaints/issues of people with the same thing happening and that gm and their service and customer satisfaction departments quite simply explain it away as "well, there's nothing we can do" despite, what appears to be, clear evidence that this major power train problem has been completely ignored. Now, I'm looking at a bill of $3000+ (dealer cost) to repair and from what I've seen, others are having the vehicles fixed at least the $4000. I will do whatever I can to recoup any repair costs that this major issue has caused. It is beyond frustrating that I only had the vehicle for about 100 days and not even 3000 miles on it (after the 90 day/3000 mile warranty had expired) to only fork out thousands of dollars for an issue that a major automobile company should have recalled. I can tell you that through this experience, I will never purchase another gm vehicle again because of their incredible lack of consideration to make this right with all that have had this issue. I hope to hear from someone very soon in regards to this matter. It's unfortunate that many people have suffered a great financial loss because of a clear decision by gm to avoid correcting this powertrain problem. I appreciate your time and efforts.

My 2007 Acadia, just a few months outside its 5 yr power train warranty, experienced a transmission failure at highway speeds. It suddenly started over-reving and would not shift into certain gears. Researching this on the internet shows many many complaints about the GMC Acadia. This appears to be called the "wave-plate" failure. Unfortunately, most people apparently have experienced this between 50-70k mileage, which is exactly where I am. I would highly recommend GMC institute a recall on this vehicle because this appears to be highly common, and a safety risk at high speeds.
