general problems of the 2008 GMC Acadia

The traction control turns on and then the shifts don’t work and I can’t drive since there is no speed also the rpm and the gas the speed and the battery gages start flickering up and down then I turn off the truck and it continues to work fine but after 40 miles or so it does it all again.

My lift gate door fell and hit me in the head out of no where and my car is not on the list for the recall for that exact problem. My airbag indicator goes off all the time even if no one is in the front seat. My speedometer barely works, it goes completely around and I can't get it to reset. I took it to the shop just to be told it's a sensor that causes it along with the slow cranking but they didn't know which one it was because my car has 4.

Takara recall it keeps shutting completely down in the middle of highway and this affects everything steering, complete loss of power to vehicle. No codes to indicate something is wrong !!!! extremely dangerous this has continued to occur even after parts have been replaced brand new. More than 5 times already. This will most certainly lead to death. I have 3 children with me at all times. That's 4 life's that could be lost because of this problem!!!! . We have been extremely lucky because it has shit down in the middle of the night and bridges where there is nowhere to get on the side but remain in the lanes where traffic is 70 mph and up!!!! this needs to be recalled immediately!!!!.

On 4 separate occasions within a 3 week period the vehicle would accelerate while driving without driver prompts or control (rpms revved from 2000 to over 6000 and speed would increase from 50 mph to over 85 mph with accelerator pegged to the floor. ) the only way to correct this was to put the vehicle in neutral, coast to the side of the road, stop the vehicle and turn off the engine for 10-15 minutes, then restart it and it would run normally for short periods of time. If I drove the vehicle for more than 30 minutes at a time it would react this way every time and nearly caused me to hit 2 vehicles on the interstate. On one occasion I had to impact a guardrail to slow the vehicle down. I took the vehicle to a certified GMC dealership who stated on both occasions they could not repeat the problem after driving it for 5-10 minutes or less than 15 miles. When I informed them that it only occurred after 30-45 minutes of driving, the technician stated he didn't have time to drive the vehicle that length of time or distance and went on to say no diagnostic codes were tripped so there wasn't any repairs he could do or that GMC would authorized. The vehicle was under warranty. . Read more...

Car loose power and stabilitraker control, press car gas pedal and only goes to 20 mph it happen anywhere highway and regular street.

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.

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!.

When travelling home on the highway after school shopping with my two children my vehicle suddenly reduced power, became uncontrollable and wouldn't allow me to get out of the way of the rapidly approaching vehicles behind me in time. I was able to get to the shoulder, after the reduced engine alert appeared. Stabiltrak was also disabled and one more feature I cannot remember. I had to shut my vehicle down and sit with two children in the car waiting for the car to somehow right itself. After 10 minutes I tried turning it on and the errors were gone and the car drove again, except rough. I took it to the local auto store and the diagnosed it with the code reader as tac. Throttle body. The person at the counter said they see this all the time with this vehicle. In fact, it should be a recall since it's so common and a clear flaw in the design. To the tune of $199 you can replace the part and have the same thing happen all over again at some other random, unsafe time! thank you gm for yet another unreliable family vehicle. I will have no choice, but to replace the part, as this is the car used for every day transportation in my household to school, work and back. Researching the internet horror stories can be found everywhere. It seems tragedy has to happen to make this $200 part a recall. Please redesign and replace. This mom cares for her kids.

When I accelerate and get to 40 mph the car begins to shake randomly, intermittently. Then the service engine light came on, then the traction control shut off and the light to service traction control came on then the car drop the speed from 60 mph to 10-20 mph! when I tried to accelerate it did nothing ! the speed wouldn't increase at all then it started running fine and then a few miles down the road it did the same thing, dropped speed from 60 to 10-20 mph! I pulled over and shut the car off and when I restarted it the same lights were on and when I tried pulling away it would only go up to 10-20 mph for a few miles then it got up to 60 mph for a few miles just to drop again! I had my 11 month old grandson in the car that was dangerous! I was on townline road and manito blacktop that are very high traffic.

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.

While driving the vehicle at a normal speed (55) on a highway, a dinging sound comes on and the car goes into reduced power mode, losing speed. The stabilitrak and the traction control warning comes on. This makes it difficult to cross traffic at intersections as the car will barely accelerate. There is no warning that this is going to happen. Also, the cars behind you do not know why you are slowing down. Then when you turn the car off and restart it, the lights go off and the car drives fine. After three trips to the GMC dealer, the throttle body was determined to be the problem. GMC has issued special circumstances warranty on the 2007 & the 2009 but not the 2008. I do not feel that the warranty is sufficient. I do not understand why there is not a recall because after searching the forums, I have found that there are numerous complaints with this happening. I had my grandkids in the car with me and we could have been hurt when we had the sudden loss of power we experienced.

Power steering failed and transmission stuck in 3rd gear from a stop, couldn't move out of the way of a car and got hit.

My family and I were driving out of town and then started to feel the car jerk at times and then out of no were it said stability traction control off and reduced power of engine and then engine started to make a terrible noise and shacking like it was going to give out. I could barely pull over. I have taken it several times in to get checked for the stability and they can never find anything wrong and they say its one thing and all I seem to do is pay for something that doesn't need to be fixed. This same issue has happened 3 times since then.

Coming home from out of town I noticed my Acadia started jerking, yet there was no check engine light well nothing telling me that something was wrong planned to take it to the mechanic the next day, when I got up the next day to take it in it would not go in reverse and would only drive less than 20 mph suddenly the check engine light came on being my only source of transportation I towed it to a mechanic shop, the mechanic told me that it was the transmission but he could not offer a reconstructed transmission because the 2008 transmissions came out faulty that I would have to purchase a new one and that GMC knew about this so they put out in the market renews and improve ones. . . . . Total cost 3,417. 00 not to mention interest on it due to having to borrow the money since I didn't have it. My question why wouldn't GMC put out a recall instead of improving it for the owners to purchase.

The transmission had been hard shifting from 3rd to 4th for about 200 miles. At 25 mph while turning through a very busy intersection the engine revved shifted through what felt like every gear, the car lost acceleration power; going from 25 mph to 10mph. Parked the vehicle. Restarted to find that only first and second gears worked and the check engine light illuminated. During the 200 previous miles of concern; I had heard a faint whine during acceleration. The first time any trouble occurred the vehicle was stopped behind a school bus loading and while I applied the brake (still completely stopped) the car lurched forward. I immediately shifted to neutral, not wanting to rear end the school bus.

I just had the clutch wave plate break into pieces inside my transmission causing us to almost get into an accident as my kids and I were getting on the freeway. We lost our gears and had to be towed. I looked up the issue and it sounds like this is a more than common issue with the Acadia at this mileage. If this is such a well-known issue why does gm not fix this issue?.

My 2008 GMC Acadia gave me the scare of my life. I purchased my vehicle just last month and was very proud, I have been dreaming of this car for a while. However while traveling to my sons track meet my Acadia started jerking as if it was not getting any gas and the engine started making a loud humming or buzzing noises on farm market 521. The car slowed down to about 25 miles. Despite my continuing to press the gas pedal. I ended up jerking my way onward with my hazards on. I had cars screeching and flying around me. My kids and I are a nervous wreck. The 521 does not have a shoulder to pull off on. Miles later varying speeds as low as 15 and up to 35 mph I found a gas station (thank god) & pulled over. I powered down waited a few minutes then restarted the car. It started normally but I noticed I could not go into reverse while trying to leave the parking lot. I made my way forward all seemed well but 3-4 minutes into driving on 521 the same thing happened and now my check engine light is on. I started to panic I'm not familiar with the area. This is my first time here & the 521 is the only major road on my gps. I put-putted along and finally made it to the track meet in the middle of nowhere. Called my husband to come and check the car. After his look around he thinks my transmission is going out. He took the children in the suburban while I drove slowly ahead. Then I get a new message - engine hot idle something - I freak out and pull off as soon as I could. He ended up towing me home. I am one week past the 30 day warranty this sucks. I really love my Acadia & am very possessive of her, no one else can drive her, I don't want my kids to touch her. I take excellent care of her, she is clean, driven with love, but just don't understand what happened. I'm scheduling to take her to the shop in the morning, husbands mad but I'm hoping this can be resolved quickly.

While driving car bucked and shifted irregularly, transmision slipped, no power, no reverse.

I was at my son's baseball game and went to move my vehicle when I was pulling out of the parking lot and the vehicle started reving and would not move other than coasting (since I was on a hill). I was 3 hours from home and had to have the vehicle towed to the tune of $300. 00 +. I have since had to have the transmission replaced. This has cost over $4500. 00 not to mention having to drive 2 vehicles with my family since the Acadia was the larger of our vehicles.

About a week ago my family and I were driving home from vacation and had been on the road for about 3. 5 hours. As we pulled out of a driveway about 5 minutes from our home the car engine light came one, the car would not gain speed like normal and it began to over heat rapidly. We took side roads and slowly crawled home. I took it into the shop the next day and it came back with a crack in the radiator and codes p0700 and p07016, which they confirmed to be a transmission issue and suggested to have a specialist look at it. I did some research and found that this are common codes that come back for the 2007 and 2008 Acadia's that require a rebuild/replaced transmission with an average cost of $4000. This is a known issue with GMC for many years and they have yet to acknowledge it. I am very lucky to not have had a worse incident in discovering this issue, but I am very concerned that at any moment the transmission will go out, and we do not have $4000 to drop into a new one, especially when I just spent $650 on a new radiator. These are not problems that a reliable car, the 2008 Acadia, under 100,000 miles should be having. GMC needs to own up to these issues and take action to correct it before something more serious happens.

While in trafic, my engine revved up and my vehicle jolted forward when my transmition stopped working. If anyone would have been behind me, there would have been a major accident.

While driving on a highway, the car went into neutral and lost power. After a few seconds, it went into low gear and would not shift into a higher gear. The transmission required a re-build two years earlier at 62,000 miles and is now failing again. We were told the transmission must be re-built yet again. We cannot drive the car as the loss of power and slipping transmission is very dangerous. The transmission design, and the subsequent repair by the dealer, was faulty. As our warranty expired 4 months ago, we were a new transmission was required at $4,000.

While driving down interstate state at 70mph I came up on slower traffic and had to slow down to 60-65mph before I could change lanes. Once changing lanes and as I went to accelerate the vehicle seemed to downshift and rpm went from 1800-2000 to 5000 and the vehicle basically stalled for about 5 seconds causing a 18 wheeler to basically all but wreck to keep from killing me and my other 5 family members in the vehicle. I pulled over at the next exit and made sure there was no kind of transmission codes or anything to show up on the dash but I still checked my fluids and everything checked to ok. I had 325 more miles to get home so I basically had to baby it to the house. It happened several more times during the trip but that was the worst. I have also experience on several occasions that the airbag in the passenger side front seat turns itself on and off for no apparent reason with the same individual sitting in it who weighs 130lbs. At first I just thought it may have been the way they were sitting but I weigh 200lbs and it did the same with me. I'm hoping to get these problems resolved by dealer tomorrow but with so many transmissions doing the same thing the gov & GMC need to take charge of this issue and get the damn problem fixed before more people have issue and get killed or injured.

Warning indicators turn on for the system braking components such as abs brake failure, traction control and loss of engine power while accelerating between 35 to 50 miles per hour. Engine power decrease and the car speed and power is decreased with the loss of engine power warning. The car would just stop at this point. I contacted onstar each time this issue occurred to a diagnostic scan and each report indicated that same warning reported on the console. After 10 minutes the vehicle would re-start and I was able to drive it. This issue has re-occurred within 2 years and the GMC service department was unable to diagnose the problem but during the latest incident the mechanic had ruled the issue as low brake fluid. I've investigated this issue online on various blog forums for the GMC Acadia with the same description of braking system failure and others report the failure as an internal braking malfunction in which the master cylinder leaks into the brake booster. I'm concerned that this problem could potential become fatal is it recurs. The GMC service department refuse to look into my concern and investigate the problem. There are no visible signs of a leak because the leak is internal.

On the first occurrence I was starting to accelerate to about 20 mph after being stopped at a red light and my power steering went out and I could not accelerate. I was barely able to steer my car off the highway and just missed hitting a tree and going in a ditch and my 2 children were in the back seat. I had the vehicle towed to the local dealership but there were no error codes showing on their computer. I have since had this happen 4 more times and the last time almost ended in a head-on collision with my children in the car. I had the car towed again for the 5th time to the dealership and the power steering finally went out on them while they were test driving my car. However, the computer still did not show any error codes after this happened. As of today, which is 3 weeks later, I still do not have my car and the dealership doesn't know what to do because there are no error codes eventhough the power steering keeps failing on them. I am frustrated and aggravated and after reading online at how many other drivers have experienced this exact same issue I am disgusted that gm has done absolutely nothing to fix this serious issue.

My friends and I left a store and was pulling out onto a busy route. Speed limit is posted as 45 mph. I was idling at the stop sign waiting for a vehicle to pass. When it did I pulled out into traffic. I gently pressed on the accelerator and that is when I felt the truck jerk and then the pedal was floored!!! I was not doing this!!!! I was in amongst the traffic, trying to Dodge others, and then I tried to turn my truck off. I couldn't do it. It was not allowing me to and the speed had increased dramatically!!! I reached down and was messing with the accelerator hoping to pull it up from the floor. The accelerator was completely pressed into the floor as if someone glued it there. I crossed over 3 lanes of traffic trying to Dodge vehicles and trying to prevent a crash. I finally managed to free the accelerator. It freaks me out when I drive now,.

We purchased a new GMC Acadia on 6/16/08. Since our purchase, we have experienced a dangerous transmission issue. After coasting downhill, the vehicle fails to downshift which causes a rapid deceleration when traveling uphill. This rapid loss of speed puts the driver in the hazardous situation of a rear end/chain reaction collision on the road GMC claims to have a fix, but this fix causes the documented gas mileage to be reduced by at least 2-3 miles per gallon. They have attempted to fix this issue twice in the last 4 weeks to no avail.
