1* purchased March 2018 (acadia denali) since August 2018 in motion when I accelerate it sounds like a loud lawnmower & crackling sound in rear muffler area. Took it chevy place in glenpool, ok. They couldn't find anything. 2* on 2 occassions, in motion, the car accelerated with a loud noise & as if it were getting power & not moving then jerks & speeds up about 15mph faster & I couldn't stop it. I kept slamming on my breaks, but the break would only go in so far. I was frightened with my 2 young boys in car screaming. It's like riding a horse & it takes off & you can't control it. 3* on about 8 or 9 occassions stationary I get out of my car & it makes a really loud annoying sound like a machine/robot powering down. My kids always say, it's going to blow up 4* the most annoying, for past month. . . Stationary, every single day & time I turn my ignition off. It has loud beeping sound & check rear seat flashing on screen then shift into park flashes. This occurs every single time I turn my car off. Sometimes I have to just let it go on all day because I can't get it stop. I turn car on & off shift back & forth & it still will not go off. Sometimes it does after long periods of time. I don't have time to struggle with getting a car into park every single time I turn my ignition off. I have to beat it forward hard with my hand to the point my wrist is bruised. Now I have to use my foot to kick gear shifter into park. I'm afraid t's going to roll out & or down and hit something, someone or even one of my children. Which would not be good. I've seen several of same complaints. This really needs to be investigated & recalled ASAP. My elderly mother had to call my brother to another part of town to beat the gear shift into park. This car was brand new & I shouldn't have any of the above mentioned issues. It's frustrating thinking GMC was top of the line & it's not.

Oil changes at dealer performed every 3k miles. At 88k miles, shortly after drive train warranty expired. The check engine light appeared. Full diagnostics performed by local dealer stated timing chain buffers were beginning to fail. Est cost $3500. Advised that since the light comes on/off intermittently, okay to wait to see if problem worsens, which may be many years, if ever. At 92k miles, while on highway, the transmission wouldn't shift gears, rpm's climbed, pulled over vehicle where it stalled and wouldn't restart. Vehicle towed to dealer, where tested and determined that engine needs replacement due to loud metalic engine noise and metal shavings in oil. Estimated repairs from two GMC dealers of $6600 to $7600 for re-manufactured engine. Local dealers have stated that timing chain buffers is a very common problem with 2008 GMC Acadia and vehicle should be recalled, but is not due to the cost of engine replacement. Contacted GMC (belva - senior case analyst) to describe case and they responded that they will not assist in the repairs because: 1) vehicle was purchased used - stating that all such purchases are 'as-is' from dealer and its up to the consumer to do due-dilegence before purchasing, 2) vehicle power train warranty expired by date shortly before purchase, and 3) power train warranty is now 3 years past the date, regardless of when issue first appeared. GMC senior advisor also stated the she recently purchased a used gm product, and the engine failed shortly afterward at 100k miles, and gm will not assist her either, as that is also out of the date range of the power train warranty. Engine was manufactured in the k-gm (saint catharines, ontario) plant.

My husband was driving our 2008 GMC Acadia and the power train started to make a whining noise, when the gearbox shifted the noise stopped. A minute later he stopped and then when he tried to proceed forward the vehicle would not shift into any gear and the car would no longer drive. We had several people in our vehicle, mostly kids, and had to recruit bystanders to help us push the vehicle off the road to a nearby parking lot. This is a huge saftey issue! my family had to stand on the side of the road while my husband and some gracious strangers had to push the vehicle since it was no longer drivable. And they we had to wait for someone to come get us. I have seen several complaints with the same scenario and really think this issue needs to be investigated. And this worst part to this whole situation is that we are military and are currently stationed overseas and will cost us over $5000 just to have the part shipped here.

Transmission. Problem shifting. . . 3rd gear. Vehicle would attempt to shift at 40mph but unable to do so. Engine would rev up then shift extremely hard with a loud clunking noise. Took vehicle to local dealership who informed me transmission would need to be replaced. More cost efficient to replace than to rebuild. No third gear. Transmission should not need replaced at 75,000 miles.

I was driving during daylight hours on the highway and I pressed on the gas to accelerate because there was a slight incline on the route I was traveling. When I pressed on the gas pedal, there was no acceleration and I got nervous that it might be the alternator. However, I was still able to drive the vehicle although it did not want to pick up speed. I exited the highway and noticed that the vehicle was having difficulty shifting gears and was making what sounded like a whirring noise from under the hood. I drove the vehicle straight to my mechanic's shop. He was surprised to find out that it was the transmission as the vehicle is routinely serviced. It appears that the wave plate failed and there was debris inside the transmission.

Transmission slipping jerks and bumps when shifting. Passengers noted there was issues also. Loses power going up hills. Took it to cochran pontiac for two years and did not correct situation, since there were no codes on the computer even though the car had no power and was jerking. Engine light, antilock braking, no rear sensors, and the fuel guage lights are now on after another dealer fixed transmission and I had to pay $1,500 and I should have not paid anything. I did not have these lights on my dash board when I went to get the transmission fixed and the dealer has not fixed them. Recently, my car lost power and died on a blind dangerous curve and shut down the engine. I was afraid to get hit and felt my car was unsafe. We put gas in and would not start and engine was hot. I had to have it towed to dealer after two weeks from getting the transmission repaired and told dealer transmission has noises in it and engine was hot and car would not start. They called and said it was out of gas and runs now, however, they did not address the issues noted above for all of the lights that were on the dash board. The gas was not the issue before car was towed since we put gas in there when it broke down. This 2007 Acadia has had issues since 2011 that continue to present and this SUV is known to have many recalls and is unsafe. The car was taken to the dealer numerous times with complaints by the customer.
