Verified

Vehicles with a 6speed automatic transmission may develop one or more of the following faults related to a broken 35R clutch wave plate inside the transmission: Illumination of the Check Engine Light with code P0716, P0776, P0717, P0777, P2714, P2715, and/or P02723, loss of reverse gear, slipping or harsh 3rd or 5th gear shift. Removal and dis-assembly of the transmission will be required to replace the broken 35R wave plate. It is also extremely important that all debris from the failed part be cleaned from the transmission while it is disassembled in order to try and prevent future problems.

    Car wasn't shifting properly. Broke down completely to a stand still (with my 3 kids in the car miles away from my home) and needed to be towed. Diagnosis from dealership: 3-5-R WAVE PLATE BROKEN. Transmission was repaired and reassembled. This seems to be a common problem with this vehicle. Class Action law suit??

    At 38,400 miles by 2008 Acadia let me sitting on a busy roadway for 2 hours. After it was in the shop for 3 days, I was told they would have to rebuild my transmission. Great! Not very happy with this whole mess. I purchased this vehicle for daily use and also because I thought I could travel here and there for family vacations. Now I am afraid this will happen again. Just dissapointed in a car I loved. Rebuilt transmission with 38,000 miles. What next!

    After a trip from Texas to Florida and back we began to experience issues with the transmission and within two days we had just about lost 3rd, 5th, and reverse gears. Mileage was at about 117,400. Knowing the seriousness of transmission issues it was immediately taken into a mechanic. He was able to find the service bulletin that described the issue. Luckily our mechanic is a good guy and tries to fix the problem with the least expense to the customer. He was able to access the transmission at the rear and pull out the guts until he found this broken piece, http://imageshack.us/a/img687/226/ot75.jpg. Unfortunately, there is no "solution" to keep this from happening again as he had to replace with the exact same parts. Thank goodness he was able to make the fix without pulling the transmission and our total cost was $1057 instead of up to $3k or more. Being judicious and taking it in quick also helped as we had caught it early before causing significant damage. In fact, it was only the symptoms that had appeared and no codes had been thrown. I hope this report can help others. We have since purchased a used Toyota Sequoia and are in the process of selling the Acadia as I'm not inclined to play roulette with when this will happen again.

    Like other's owner horror stories, car is in the shop with no reverse and 3 5 wave plate busted....of what can be said without openning transmission to see what other damage there. Was told that I am looking at 5K to replace the damn thing....now I am PIST, cause this is my first expensive car with all the bels and wistles, except the navigation system stopped working about 3 month after I purchased car - used with 30k miles on it, and the DVD player, which was so my kiddo can be entertained on long trips, stopped working 6 month later. all within months of expired warrantly, ofcourse. Oh and the leaking sunroof.....#@$%#^ I have NEVER seen a car LEAK every time it rains. How can you make such poor quality product???

    I first do my research on the problem and then call Buick customer support and let them have it, demanding that THEY cover the cost since they put a faulty part, (which is bound to brake after warranty expires) to begin with. Get transferred to another department that "handles" such issues, and am told that dealership manager will call me back with "financial assistance" offer...Well 2.5k out the door is better then 5K, I admit, but HEY, why should I swallow $2,500 of my hard earned savings???? GMC SHOULD!!!
    Can't we do anything to make this issue a recall item?

    Just informed of my wave plate being broken, to the tune of $2660+tax, and if debris in valve body, brand new transmission. Nothing like "quality" GM product. 62,000 miles is a little low to have this kind of problem.

    Driving along at 55mph on highway in cruise control, transmission slipped out of gear into like 3rd gear, limped it home 60 miles (real joy). Ran code reader on it P0700 and P0717. Reset codes, came right back 2 houses down. Read all the threads on-line, limped 8 miles over 2 hours to the dealer turning off car and restarting, erasing codes when that didn't work, wished I lived near tall bridge to throw this POS off of since this is our 3rd major issue after owning this SLT2 for less than 2 years! We were lucky enough to experience the water leaking sunroof and seam issues you can search on and the car has mold we can't get rid of. Wave plate shot and needs to be replaced. My super conservative Dad even is telling me to sell the POS the day I get it back and eat the loss and buy non-GM. Funny coming from a WWII vet who owned nothing but GM's over the past 60 years. GM is not the same as it was. I see a Honda in the near future.

    The transmission just started slipping in 3rd gear. I'm afraid that after reading all of these complaints that the wave plate might be fixing to go. I'm taking it to the dealership tomorrow. Update: Same ole same ole. Broken wave plate. The service writer stated when asked if this was a common problem ? He very candidly said yes. As these vehs start getting miles on them which in most cases comes after the warranties have just expired,he expects business to really pick up. I will say that my dealership bent over backwards to accomodate me. They gave me a new loaner vehicle and prorated the cost. It's still going to cost me right at $1500.00. It's a big expense right at Xmas time. GM needs to man up. I also filed a complaint with the NHTSA. If you have a 2007 thru 2011 Acadia and it's still under warranty the transmission slips right? Get it fixed on their dime. This is going to get somebody killed. It's not a matter of if these transmissions will break...it's when...

    Transmission slippage and hard shifting. No codes. Had dealer take a look. 35R wave plate. Tranny needed to be rebuilt. 5 months out of warranty. GM needs to step up and extend the warranty on this part.
