  • 58,000 miles


My 2007 GMC Acadia's first started having transmission problems in December of 2012. The vehicle started having issues while trying to merge onto the highway or depressing the gas pedal for a passing and/or merging purposes, this would somehow revert into a neutral position, having the rpms rev up and no forward motion, until it's sort of caught up itself by backing off on the accelerator. The other issue involved putting the automobile into reverse, not only at times it wouldn't go into reverse but instead would revert to a neutral position, until you started all over again with the process of putting it back into park and then back into reverse. Never was there a light nor a warning by the cars sensors or any other symptoms that would give an owner a warning that there would be a problem coming soon. In any event, after having the symptoms described above the car somehow dropped into first gear and cannot shift from that position and finally, the transmission light came on. At the moment, I am in the process of filing a complaint with GM and at the advice of the GM representative, they advise me to have the dealership look into the situation. In my opinion, this is a very dangerous situation. Seeing all the same complaints on the internet leads me to believe that there should be a further discussion on the transmission of the 2007 GMC Acadia. Thank you

Acadia 6-cyl

  • 88,700 miles


We were leaving my sons basketball game tonight and when we went to enter the interstate the tachometer went to 5000 RPM's and the vehicle was not moving. As I am setting along the interstate with vehicles hammering by me at 75mps I tried to go again. To no aval the vehcle would not move. I called a tow truck, moved my wife, 11 year old son and 16 year old son over the guard rail to safety. The transmission is bad, along with all the others posted on the internet. What gives" this vehicle has 88,000 miles on it and im told GM wont fix it because th 5 years is up on the warranty. What does 5 years have to do with anything when this is happening everywhere to this particular vehicle?"

Transmission dead-racing RPM without gear shifting, broken wave plate inside transmission is the cause. Water leaking from sunroof when raining, constant whinning in steering column. All these major problems under 75K miles.

Acadia 6-cyl

  • 99,500 miles
While accelerating vehicle started to shake between 30-40 mph. Shaking subsides at around 45 mph. This started around May 2012 with 99,000 miles on the car. Took the car to the dealer to have it checked out because I though it was the transmission. They thought the tires needed to be rotated and balanced, which did not fix the problem. By 106,000 miles it was so bad that the vehicle could not be driven safely. This time the dealership said it was the motor mounts, which did not fix the problem. I had them keep the car until they found the problem. After 2 weeks they determined that it was the transmission! after the transmission was replaced the vehicle drives great. I have read hundreds of complaints on the Acadia transmission and there are likely tens of thousands of cases just like mine. There should be a recall for the transmission on this vehicle.

9/27 as I was driving in a residential neighborhood to take my daughter to school I was approaching a green light at a four way and started to accelerate to 35 mph from a complete stop to cross four lanes of traffic. The vehicle reached 35 mph and although the speedometer stated 35mph the vehicle stopped moving and stalled and started making a churning noise coming from the engine. At this point my front end was in traffic under the light that was now turning red so I had to think quick and put on my flashers to alert the other drivers that I was having difficulties as I couldn't get the truck to move. When I pressed the gas pedal the engine just roared but no movement. Once other drivers were alerted I had to coast backwards from the incline at the light and maneuver onto the side of the road. I turned the truck back on and it came on and miraculously I was able to drive it 5ft off the road before it stalled again. I had to be towed to a dealer as of today I was told it was the transmission but the dealer had to contact GMC to report all major engine failure before proceeding with any work. Last year in Dec. My truck started making whining noise and I immediately took it to the dealer to find out that the camshaft had went bad and spit metal in my motor causing me to have the engine replaced. Because I was the second owner of the vehicle GM didn't want to pay for the total bill under the powertrain warranty and the fact that I was 3000 miles over the powertrain warranty itself. They did pay a third of a $5000 bill and I had to pay the rest only to have them place a recall on the camshaft and to reimburse me half of what I paid. This situation with the transmission reminds me of the rollover with the Firestone tire Ford had years back but the difference is that Ford and Firestone took responsibility. Please make GM responsible before someone is killed.

My transmission went out after 58,000 miles and 5 years and 5 months. So I am over my warranty by 5 months and am out $3300. In doing some research, there seems be an abnormally high incident of transmission failures on the 2007 GMC Acadia. Some bloggers indicate that the Acadia models have big issues before the 2010 model. Is there a systematic issue that GMC needs to address or am I just unlucky?

Basically bottom line is this is the 4th major thing I've had my Acadia in the shop for. This repair of a rebuilt transmission is costing me $3500 out of my pocket. Supposedly the GM customer rep does not think there is anything they can do for me because my car is 5 years old and 131000 miles.. that is just bs!!!!! I spent $40,000 on this car to drive it longer than this and for all the things to start nickel and dimming me is ridiculous. The mechanic at the GM certified garage told me that GM used a prt in the transmission on the 07-10 models of the Acadia that cost them 1.69 and that they know they should have used a part that cost them $39, so this is the part that is breaking in the transmissions and making them junk and having to be rebuilt or new ones put it.. GM didn't want to recall the 07-10 models because it would have affected millions of cars, so they are just letting the owners suffer for their stupidity and lack of responsibility. My biggest complaint after the money is the fact the my child was driving my vehicle when this happened, he was panicked as he could not go over 30mph on a very busy road and the vehicle started to shut down on him!! he is very lucky the vehicle made it to a safe place and he was not rear ended as the car just stopped on him!!! really GM when are you going to recall these models and make it right for all of us that have to encounter such a high expense?? I really can not afford another vehicle or the $3500 to repair this one, but that is my only choice!!!!

My transmission has to be replaced at 131,000 miles and a cost of over $3400 out of my pocket. Well here I am again... this is the third major thing that has happened to my 2007 Acadia.. I had to have all new timing chains put on 103,000 miles, had to have my service tire sensor fixed at 112,000 miles, I have done all the re-calls for the sun-roof leak, the heated windshield fluid, and whatever else hs been re-called on this vehicle!!! my 17 year old son was driving my car in heavy traffic on a major highway when the car just stopped and then he could only get it to go 30 mph. He is lucky he was not rear ended. I took it to the dealer, it will not go over 30 mph and reverse. I spoke with the head mechanic at the GM garage that is putting a new transmission in my Acadia at the cost of $3400 to me, and he told me that all the 2007-2010 Acadia's have a part in the transmission that cost GM $1.69 instead of using the part they should have used that would have cost them $39. He said GM know they should have recalled all the 2070-2010 Acadia's but chose not too because it would have been millions of vehicles involved, so instead "thank you GM" for screwing all of us and now we have to pay for your mistake and cut backs....

The vehicle started over revving while changing from 1st to 2nd gear, slowing down in busy traffic. There were many in traffic who were blowing their horns and swerving to avoid my vehicle, which at the time contained my wife and three small children. The following day, the vehicle would not go into any gear. Fortunately when the transmission failed, I was on a private road with minimal traffic.
