general problems of the 2008 GMC Acadia - part 1

Transmissions will not shift out of 1st gear. And puts out a 752 code. This can happen at anytime. Vehicle will suddenly lose power at any time.

�service air bag� had been on my computer screen for a few days and isn't going off. I purchased this vehicle used and they told me it means something is unplugged. I took it back only to have it come back in months later. It sometimes happen as I'm driving but lately it's there when I turn the ignition. I also have shifting problems out of first gear and sometimes second. I was told it's the wave plates and it's a known issue. How are these vehicles still being sold with the same issues over and over! this happens all the time as I'm driving.

The contact owns a 2008 GMC Acadia. The contact stated that while driving at an undisclosed speed, the vehicle stalled without warning. The vehicle was towed to the residence. Wilkins Buick-GMC 6913 ritchie hwy, glen burnie, MD 21061, 410 999-1419, was contacted and the contact was informed that the engine and transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 142,000.

Tl-the contact owns a 2008 GMC Acadia. The contact stated that the instrumental panel service stability track control illuminated remained illuminated and the engine light flashes and the gear locked in fourth gear, the contact had to release the accelerator pedal to be able to have the gear release from fourth gear. The vehicle was not taken to the dealer to have a diagnostic performed. The manufacturer was not contacted. The approximate failure mileage was 187,000. Li.

This vehicle will all of a sudden start swaying from side to side and the stabilitrak light will come on. In addition, the transmission will suddenly seize up, losing acceleration and nearly causing a crash. The engine will also state that it is overheating, all of a sudden and the vehicle will shut itself off and smoke will start coming from the engine. This has happened while going between 35 and 65 mph. On the streets and highways. My children in the bucket seats in the back were sleep and their heads hit the window. They sustained injury. That was on a regular street and the speed limit was 35 mph. I was within or slightly under the speed limit when the vehicle started swaying unexpectedly. When the road is wet, it will sway from side to side on simple curves in the road. I have had the transmission replaced twice. Due to the safety concerns and fear of my family being fatally injured, it was around christmas time. I have had to park the vehicle. I have contacted GMC by phone several times with no response in return. I spoke with someone and was informed to report it to NHTSA. Maybe something can be done about this before a death occurs.

Tl the contact owns a 2008 GMC Acadia. The contact stated that the gear shifter seized and was unable to move into park. The contact stated that the vehicle exhibited the same symptoms as listed in NHTSA campaign number: 09v073000 (power train). The vehicle was not taken to a dealer to be diagnosed or repaired. The manufacturer was notified and stated that the vehicle was not included in a recall. The failure mileage was approximately 91,000.

There is a recall on the convertrr post that causes the engine to seize up and pull to go into the engine. . When started nothing comes out of the exhaust pipes as they are clogged making it dangerous to operate. . The recall ignoramus this year, make and model for the same problem however after contacting GMC repeatedly they say that it doesn't include this exact VIN. . I have already had the engine replaced once due to this problem and ther dealer failed to diagnose it properly and acknowledge that it had the same problem as the recall in other vehicles ofthe same make and model. . . The vehicle sizes up at any rate of speed and the exhaust is clogged making the vehicle dangerous to operate.

Worst vehicle ever.

My vehicle has 85,500 miles on engline and transmission. I bought the vehicle when it had 36,000 miles on it. I have never pulled anything behind my vehicle that would put strain on the transmission. I took it to the mechanic and found out I needed a new transmission. The vehicle would stay in 1st gear and would not shift to a higher gear.

I needed to add this information to complaint 11113379. Sometimes the care would be shifting okay and going 55 miles per hour and then it would downshift to 1st gear and stay in first gear.

This is the worst viechle we have every bought. You name it an it has gone wrong. Transmission twice, timing, power steering, tailgate, we have never pulled anything with our car. When it rains the steering locks up. . One minute we are going 70 and bam the car turns off. I can keep going. GMC pretty much just said OH well. This have happened so many times I lost track.

For the past 6-9 months I have been experiencing problems with unwarranted speed shifting, hard shift changes & overall transmission issues. I have had my car to transmission specialists almoat on a monthly basis for these issues. I was told by the specialist that he repairs at least 3 cars of my same make & model per week. He said he is noticing a very common failure in each vehicle. My vehicle has power but the speed & gear shift are huge safety issues, as it is very random & unprovoked. I have been driving on the highway & my vehicle would just stall or shift. I have had to carefully pull over to the side of the road to avoid a major accident.

This car came with a 30 day and/or 1000 miles warranty. Within a week pass the warranty it started. The radio illumination started to go out we would have to tap on it to get it to turn on so we could see the time etc. Then it would not come back on at all and all chimes went away. , stopped working altogether. No turn single indicator, seat belts, back up warning, door ajar etc. The passenger side air bag indicator would say no one when someone was sitting in it and while driving blink between the two. Also air bag needs maintance indictor in dash will flash while driving. Park assistant on and off will flash while driving. The steering will move in itself while driving and around bends/turns in the road and worsening on highway! to the point I do not take my children on. There is also a faint burn smell around front floor. I decided to take it to the local advanced auto parts store and have them hook it up to see why I lost my radio, steering etc. They tell me that it was a dead battery cell and that my battery is located in the floor of this vehicle behind the passenger seat. By the way this vehicle does not have a sunroof all the windows go up tight as well. I called my mechanic who I've known for years my family has went to him as well and asked him to assist me in the battery issue. So we get there he opens the floor behind my seat and we discovered the battery is underwater dark sludgy water! the battery is replaced after a very unprofessional and disrespectful experience with this particular establishment by now I am at my wits end. I've exhausted all efforts with them! I paid to have a GMC certified mechanic run diagnostic on these issues at hand and to my thinking they determined to be flood and/or water damage and would need further diagnostics. However puzzling the VIN is clean and no recent or active recalls. I am barely into this contract 3 months!.

Transmission problem I am being told. . . No warning signs! stopped at a red light and went to accelerate and Acadia would not go faster than 25 mph! now I am being told I need a new transmission at 95000 miles GMC is a joke! will never own another one!.

I purchased a used 2008 GMC Acadia in may 2017 ever since I purchased this vehicle I have had nothing but problems I purchased this vehicle because my daughter is a senior in high school and I knew that we would be needing it to travel from state to state for college tours. Every since I purchased we have not been able to travel because of the continuous light to come on, continuous codes that comes on and it causes the car to run horribly I am spending $20-$30 a day on gas and I'm also noticing that the oil is just evaporating but I'm not seeing it on the ground I continue to take it to the mechanic he continue to fix things that the codes gives him. I'm still spending money and I'm still not getting any results I have not been able to travel in this vehicle because I refuse to get on the highway with my child and breakdown in the middle of nowhere. What we need to do is start a petition with GMC because if everyone is having these problems then it is a serious problem I am to the point where I am ready to start a lawsuit. I mean let's be honest what are we waiting for either us or one of our loved ones to die and is known death trap. There are so many recalls on this vehicle that all of them should be just called in and repaired apparently it's a problem with GMC assembling the vehicle and they do not want to own up to their responsibilities and it's not fair to us that I lives are at stake.

Happened 2x already. Vehicle is in motion high rate of speed 55 to 75 mph, engine light comes on and vehicle starts to slow down drastically on its own. Eventually the engine shuts off loosing all power and power steering. Happened once on highway and once on a major busy road. If you try to accelerate there is no power. The vehicle eventually stalls without warning. Once I could not even tell the engine stopped because the dash board lights still worked. Pulled over, wait 10 to 15 minutes and then try to start vehicle. It will start and everything seems normal again. Each time this happened I had my 3 kids in car. Not safe at all. Took it to dealer and they have no clue. Said it may have something to do with transmission.

Approximately 3 weeks ago, my 2008 GMC Acadia was serviced at 140,000 miles for worn out timing chains. Now, I am looking at problems with my transmission. How convenient. Within three weeks this vehicle has failed on me. The timing chains were rattling in turns when it was taken into the dealership and the problem was discovered. I actually visited and left the dealership several times before the problem was diagnosed, so I was riding around with a faulty part in my engine. The transmission went out after I had exited the interstate at which point I could not accelerate more than 10 mph. Good thing I was not on the interstate when it decided to stall out on me as I can only imagine how disastrous that would have been. The 2007 and 2009 GMC models were recalled for timing chain issues, never the 2008 model. The transmission problem is related to the 3-5-r wave plate, which had a 20,000 mile extension from gm to cover the repair if this broke, which of course I am out of, thus the repair costs for both defects are my problem. I do not understand how they will not back their products knowing that they are faulty. Gm needs to step up and man up to the fact they have inferior products inside these engines and transmissions.

Citizen petition - 2008 GMC Acadia, timing chain and 3rd/5th reverse clutch wave plate defect the consumer would like the vehicle to be included in a recall. Updated 09/21/2017.

I have a 2008 Acadia which is equipped with a timing chain that has been known by general motors to prematurely stretch and fail, and which can cause serious damage to other engine components, as well as activate certain sensors either prematurely or not at all. Your engine and key components and crankshafts and sensors rely on the timing chain in order to function properly. When you're driving in your vehicle and the timing chain gets stretched, the check engine light flashes on, the engine and transmission will power down and shut off, a loud buzzing sound will occur and hope to god you are not on the highway, because general motors knows about the defect but still will not issue a recall on the prematurely stretched timing chains due to the extensive cost of repair. They have extended warranty coverage on certain similar models in 2007 and 2009, and have offer full replacement of the timing chain up to 10 years and 120,000 miles, but despite the same issue occurring in vehicles made in 2008 with the same defects, they have denied my service request. This a very costly and extremely unsafe condition to drive the vehicle in. It is terrifying when your engine misfires and powers down, and your warning lights flash with a loud buzzing alarm sound blaring through the speakers. The traction control, stabilitrak system, and airbag sensors are all adversely affected by the defective timing chain as well, and the manufacturer is well aware of this defect and unfortunately will probably not be held responsible until someone is killed in an accident as a result of a defective timing chain. I'm so disappointed in this vehicle and the lack of accountability through the manufacturer. They know it's a problem. They are aware of the defect. They even extended coverage to replace up until a certain point, but beyond that, they do not care.

2008 GMC Acadia with just over 30,000 miles started jerking a couple days ago when gears would change from first to second. I took it to my mechanic today and what do you know - I need a new transmission. I can't believe that GMC has done nothing about this after reading all of the complaints. A $3000 repair if I'm lucky. My car looks like new and is hardly driven - and the transmission goes out?? crazy.

Vehicle lurches when going from 10mph to 20mph was going downhill would no longer accelerate once I was at 40-45 mph it revs up to 4 and nothing had to coast downhill turn into a parking lot and stop the car. Took it to the dealer who sold it to me and he was able to replicate the same issue under similar circumstances. The dealership will look at it but I bought it used for my family at 99,950 miles 8 days ago.

The contact owns a 2008 GMC Acadia. While driving approximately 55 mph, the vehicle stalled, the brakes seized, and the traction control and abs indicators illuminated. The contact lost control of the steering. The vehicle was able to restart on the first attempt. The failure recurred five times. The vehicle was not diagnosed or repaired. The manufacturer stated that there were no recalls for the vehicle. The failure mileage was approximately 131,000.

The contact owns a 2008 GMC Acadia. While driving 35 mph, the vehicle hesitated while the contact attempted to accelerate. In addition, the vehicle would not start when prompted on numerous occasions. The vehicle was diagnosed as having a faulty part within the transmission. The vehicle was not repaired. The manufacturer was not made aware of the issue. The failure mileage was 131,000.

While driving, the vehicle began to idle sporadically. Eventually, it started to idle and not shift into the next gear. Finally, the check engine light came on. When took it to a repair shop determine the codes associated with the check engine light, and found p0700 and p0776 codes. These codes reference a well known problem encountered in the 2008 GMC Acadia. The waveplate may be broken, and cause issue in the 3rd, 5th, and r gears. So, now the vehicle doesn¿t shift into any gear, and I will have to pay out of pocket ($4k) for an issue that gm knows is an issue, and has since corrected in the later year models. I called gm to see if they would offer any type of assistance, and was told no, due to the mileage on my vehicle. I am currently at 143,000 miles. Regardless of the miles on my vehicle, if gm placed a faulty part in their vehicles, they should be required to place a recall to fix it, and not have it be the consumer¿s responsibility!.

Transmission started getting sluggish around 88, 000 miles. Vehicle wouldn't crank due to electrical stabilizer, now my sunroof is leaking. Dealership is going to charge me $275 dollar to unblock the sunroof drains what a rip off when this is the three time I have had the drains cleaned and the sunroof still leak. This has to be a GMC problem that they refuse to acknowledge. The transmission is still under the GMC warranty so thank god I don't have to pay out of pocket for that. The electrical modules seem to be okay for now but at any giving time the vehicle may stop working. GMC should own up to these problems and look out for their customers.

Driving down the interstate when the transmission burnt up inside. The transmission shop said this was a very common issues with vehicles of the same make and model of ours. If there is so many of these going bad shouldnt this be fixed by the manufacturer???.

The contact owns a 2008 GMC Acadia. While driving 60 mph, the oil pressure gauge needle fluctuated and the vehicle was taken to the dealer where the transmission fuse was replaced; however, the failure recurred. The manufacturer was not made aware of the failure. The approximate failure mileage was 160,000.

Driving vehicle with my family in it 3 kids and wife and it just stopped working. No warning no nothing just stopped.

Get on the freeway with 30 mph, then suddenly the car stop accelerate. Luckily, I was able to merge into exit ramp. The engine light is on and the car won't move any more. I be able to start the engine but there is no acceleration.

The contact owns a 2008 GMC Acadia. The contact stated that the vehicle experienced a complete loss of power and was no longer operable. The check engine warning indicator illuminated. The contact took the vehicle to the dealer where it was diagnosed that the transmission malfunctioned and needed to be replaced. The vehicle was repaired; however, the failure recurred. The vehicle was towed to an independent mechanic where it was diagnosed that the engine was defective and needed to be replaced. The vehicle was repaired, but the failure recurred. The vehicle was taken to the independent mechanic again where the engine was replaced again. The failure recurred. In addition, the engine oil coagulated and the air bag light remained illuminated. The manufacturer was notified of the failures. The failure mileage was 110,000.

I purchased this vehicle, and was told there were no active recalls and nothing wrong with vehicle, the dealership supposedly had took it thru a hundred point inspection, immediately the air bag light came on, it started losing antifreeze and the check engine light came on , after several trips to the service dept at this Toyota dealership, I am still having issues, they fixed the small things like the water pump, the rear wiper blade, electrical but the engine light still comes on and I had it checked out and it is the transmission, it is going out, and the air bag (service air bag soon) is still on, but was supposedly fixed by a recall in 2011, either it was a bad part, or it was not serviced at all. I have been driving for 40 years and I have always been a loyal gm owner, especially the Buick lasabre which I drove for 15 years, but I am not happy with the quality of this vehicle and the dealership that I purchased it at, and they are rated by the bbb as a. I also do not like the fact that on gm commercails it states non gm owners,like come on in, we will take care of non gm owners but not the loyal ones. I think it very important to stick with american brands and love gm, just very dissatisfied with this one. I think gm should fix this car, the air bag and especially the transmission!!!!.

Transmission went out. Had to fight with dealer about the fact that this is a known issue on these vehicles. I understand I was out of warranty. But how many people expect their trans to go out in the first 100k? if you own an Acadia, expect to replace transmission between 75-85k. There are hundreds of horror stories on transmissions in the Acadia, traverse, enclave, and outlook alone on the web. Gm knows about it but never issued a recall for a sub standard transmission with faulty wave plates. But when it goes out, you get to pay for the "new and improved" version. Dealers are well versed in the failure. In addition to the trans, my sway bars had to be replaced before 50k and I had to pay for it. The headliner was damaged from clogged sunroof drain tubes which new design was installed. New style water pump. All 3 of these items were newer style replacements because gm had to redesign them. That tells you they had known issues with them and instead of standing behind their problems, they hide behind a black and white warranty policy. At the end of the day, a one off problem should be black and white. But when you know there is a major failure history that causes you to redesign components, you should goodwill the customer and proactively perform recalls.

Driving down the road pressed the gas to go up a hill and car would just rev up. Acting as if it were in neutral and it was in drive. Lost all gears. Shut it off and started it again and I had low gear. Continued to go back up the hill to get to my mechanic and when I got to the top of the hill the car lost all gears again and would just rev up. Turned it off and started it again and it let me make it a little further down the road and did it again. I then had it towed. Was very happy with this car until this happened. There was no warning that my cars transmission was going to go. The car never acted up until the moment this happened. I have since looked online and seen that the transmission going around this mileage is a typical issue for this year of Acadia. . Read more...

The contact owns a 2008 GMC Acadia. The contact stated that the vehicle failed to shift into any gear outside of first or second. In addition, the contact mentioned that the vehicle failed to accelerate above 20 mph. The vehicle was taken to an independent mechanic. The technician diagnosed that the transmission needed to be replaced. No repairs were made to the vehicle. The manufacturer was made aware of the failure. The failure mileage was 84,800.

Yet another safety issue w/2008 GMC Acadia. Dropping daughter off at school (19 degrees out/inch of snow on ground), as I'm pulling out of parking lot going very slow thankfully, the car feels like it shifted and then flashing light service traction control, power limited or something and engine buckling like it's going to shut off. I only live a mile from school and kept driving on back road unable to go over 15 mph. Had I been on a highway or going 30 or so I can't imagine what would've happened the way the truck just buckled. I let the truck sit for a few hours, now when I turn on the check engine light is flashing but the service traction control is gone soooo taking it to the gm dealer will be useless, been here before and they never find anything wrong. Hoping it's just the very cold weather making it act up but cold weather should not make this happen, unacceptable. My Acadia acts up with lights, flashing low tires, etc. Etc. All the time when it's cold and this would be the worst time for the vehicle to not work and leave me stuck somewhere. All the $ I dish out for this truck ugh, I would be better off buying an old beater and taking my chances cuz this vehicle seems like if one thing is off the truck just has a mind of it's own and everything is out of whack. Gm please stop selling unsafe cars!! I have kids and I do not feel safe driving this truck. I hope this issue gets recalled, read numerous complaints with the same issue but dealership never knows how to fix.
