general problems of the 2007 GMC Acadia - part 2

I was coming home with my five children when getting close to home my truck just would not go over 10 mph I would pull over for cars behind me to pass after I tried turning it off and restarting but it would do the same glad I was close to home that I was able to get their. I got home shut the truck off and tried to turn back on and it wouldn't I have been told that it was a sensor and replaced it and it still didn't work know I have been told that it is the motor that is bad it is embarrassing to have a truck in your driveway that you have not been able to use and still owe have the amount of what it was sold to us. They also told me that this was common on 2007 because of the faulty motor that was put into them as I read some of the reviews it should be considered as a recall because of the price these trucks go for new or used suppose ably it is a high quality vehicle and its sad that their is so many bad reviews and nothing has been done to help all the people who are having this issue as gm knows this isn't something you can say I will get it fixed right away you are talking thousands of dollars for repairs.

On my way home from work, in the middle of tunnel truck turn on check engine light, in panel " reduced engine power" and reduced the velocity by itself to 10mph. I turn it off and on again , started running but in less than 1 minute running, did the same problem.

I was on my way to work. Stopped at light. Light changed. I attempted to move and could not accelerate over 10 mph. Turned the corner. Had to pull into a business parking lot which is where I was stuck until a tow truck came because I could not move forward. I was told by the mechanic who repaired the transmission that I was not the only one he had seen who had problems with this particular transmission. Also, if you google 2007 Acadia transmission, you will see several, several individuals with the same problem.

Pushing the gas pedal the vehicle revved up and the gears slammed into gear, engine light came on and seems to have no first gear as of now. Seems it may be the wave plate within the transmission.

When beginning to drive our vehicle from church the check engine light came on and vehicle would not downshift, and speed would not get above 30 mph. When brought to the dealership the following day, we were told we would need a new transmission. The vehicle only has 50k and should not have had this issue, and it is a transmission safety issue. Had we been on a busy highway and this incident occurred, a major accident could have taken place. Other sites have listed numerous complaints about the same transmission problem occurring in various Acadia's as well. A recall should have been issued and gm should pay for the full repair as it is over $4,000.

Transmission has full failure, dealers said that wave plate went out destroying entire transmission. $4300 repair at GMC dealership.

My wife and I were on hwy 78 in loganville GA when the vehicle wouldn't shift causing us to veer off the road. Luckily no one was in the other lane. When I got to my dealership I asked the service writer if this was a common problem in the Acadia and he said very candidly yes. He further said as the mileage gets higher on these models he expects numerous breakdowns. My wife is disabled and this is her car. What if I hadn't been driving. It's going to take someone getting killed before gm admits these transmissions have defective parts. It's not a matter of if they will break but when.

Driving along at approx. 25mph and transmission suddenly lost power. The car was turned off and on randomly to apply power to the transmission for a couple of minutes to drive it back home. Thank god I had just left home! never, ever received a notice from GMC nor the dealer regarding power train problems. The car has been sitting since then (now going on approx 8 mos. Because I have not been able to afford approx. $3,500 for a new transmission. The saddest part . . . I don't even have a notification as to where to take it to get repaired.

I was traveling on the interstate when I had loss of forward momentum and a check engine light. The wave plate in the transmission broke leaving me at freeway speeds with no way to accelerate. This sounds like a fairly common problem with this vehicle.

We were driving down the interstate and my car completely shut down. . . I had no driving power. I pulled over to the side of the interstate, put my car in park, started it again, went about 30ft and it shut down again. It was towed to a GMC dealer and received a phone call that I would need a new transmission. It is very frustrating because I have read that many GMC Acadia's transmissions have gone out and they are not doing anything about it. There should be a recall on these. The should stand behind their 100,000 mile power train warranty! I have read that the 2007 and 2008 models have the defects and they fixed the defects in 2009.

We were heading home from ft. Davis and while trying to accelerate the engine would just rev and it didn't seem like the gears were shifting. We were going at least 60 mph and trying to accelerate to the speed limit. I had contacted onstar while we were driving and the diagnostics confirmed that is was the transmission/power train. We eventually ended up in pecos, TX at a GMC dealership, who told me, and onstar, that there was nothing they could do because they were already closing for the day. We got there before noon and they still didn't want to run tests or anything, but they did say I could leave my vehicle and they could work on it come Monday. We had put transmission fluid in to see if that would help, but once we started the car we noticed that the car would not reverse. Needless to say my transmission needs to be rebuilt. . . We were able to get my car back home and two repair shops both confirmed that. The second guy even said that he's had to rebuild/replace at least 4 transmissions and I had missed the recall by one year. Funny thing is I don't even remember being notified of any transmission recall, but I have received others. I haven¿t even found any online. Obviously this is an ongoing and dangerous problem that needs to be addressed ASAP!.

While on a vacation trip with the family, my 2007 GMC Acadia started to hesitate and buck when accelerating from a stop. When I arrived at my destination and pulled into the parking lot, when the transmission completely stopped working with no forward or reverse gears. I had to have the car towed to a GMC dealer and have a broken 3/5/reverse (35r) waveplate replaced in the transmission. This sudden unannounced loss of power to the wheels, could be a potential catastrophic event for the car passengers and other vehicles, trucks and buses, if this were to happen on a highway traveling at 65 mph, as there may be no way avoid getting in an chain reaction accident with the following traffic moving at highway speeds. This could be especially hazardous in high volume rush hour traffic, at night or under weather impaired conditions (I. E, fog, rain or snow). After a little research, I was made aware that this is not an isolated incident and gm is quite knowledgeable of this waveplate transmission problem, in all models with the same drivetrain platform, but have done little to step up and remedy the problem. If you are out of warranty (5 years or 100,000 miles) you are going to be out several thousands of dollars for the repairs, suffer a great deal of inconvenience and are putting yourself and others on the road at great risk. I hope this will help bring this issue to head, as gm needs to recall and repair this waveplate transmission problem, as it present a serious exposure and liability to injure and harm the traveling public.

We purchased this Acadia used in April 2010 with about 40,000 miles. In early July 2012 the transmission went out. This has been repaired under our extended warranty as of July 15, 2012. On August 1, 2013, our transmission went out again. During the first year of owning this vehicle, we have had the windshield wipers operating erratically and the radio will not always shut off when the engine has been stopped and driver's door opened & closed (possible electrical problems). We've asked our GMC dealership to address the electric, but each time they say nothing shows any errors on their computer tests. With the recent issue in a little over a year on the transmission (again!) we have found numerous sites from other 2007 Acadia owners stating the same problems and that it is repetitive. If this has been a widespread and known problem, this was not shared by our dealership. Given our vehicle has less than 100k miles and will likely have a 3rd transmission in its 6 year age, this is not a vehicle I feel safe having my wife and 3 young children continue to ride in. Unfortunately, our options are very limited financially to find a vehicle allowing for the amount of space needed for 2 car seats in addition to our 9 year old booster seat (normally cannot seat them in one row side by side by side). At this point, we are researching all options to get out of this Acadia as we cannot sink money into this vehicle to keep it running safely and not know if the transmission will continue to go out.

The contact owns a 2007 GMC Acadia. The contact stated that while driving 30 mph, the vehicle stopped shifting gears and began to jerk and lunge. The vehicle was taken to and independent mechanic for diagnosis where the contact was informed that the transmission would need to be replaced. The manufacturer was notified of the failure. The vehicle was not repaired. The VIN was available. The failure and current mileage was 90,000.

Started the vehicle this morning with remote start, got in and pushed the key forward. As I left the apartment complex on my way to the post office, I noticed my Acadia started having problems shifting past 20mph. I took it to a local transmission shop and when they drained the fluid, the fluid was burnt requiring the transmission to be opened up. I have still not had the transmission manipulated past the fluid drainage. I even took video of the speedometer and rpm gauge while it was having trouble shifting.

Driving home from the beach with my friend, no service lights were on. While driving on the garden state parkway my car was becoming sluggish on the pickup while changing lanes. A couple exits down the road the check engine light came on along with a message - "transmission hot, idle engine". I safely pulled the car over 2 exits away into the reststop and shut the car off. I waited approximately 20-25 minutes and restarted the car, all service lights were now gone. Me and my friend decided to now cautiously drive the car home since all the service warnings had gone away. As we began to pull out of the reststop the vehicle could not accerelate I then was stuck on the side of the express lane on the parkway. Since this incident I had the vehicle checked and it turns out my entire transmission is broken, not one salvagable part to rebuild my own transmission. I find this extremely ridiculous that a car with 63,000 miles that is supposed to be of good quality is having this problem. I have also found a transmission problems website/blog ranting about their transmissions problems in 2007-2008 GMC Acadia vehicles all with 60,000-72,000 miles. Clearly this is a problem that needs to be addressed, this is extremely unsafe and unacceptable. A recall should be established for this transmission problem, this needs to be looked into immediately.

Car shut down while I was driving. After awhile it started back up but it would only go on first gear so I could go more than 20mph. Then when I went home, the check engine light came on and the reverse did not work. I have read alot of complaints about the same problem with 2007 Acadias. I hope these cars get recalled because some people might not be as lucky as I was were there weren't any cars around or in the interstate.

I'm having chronic transmission problems I've spent &2000. So far on the transmission. The GMC dealer has been constantly telling me I'm having multiple issues regarding the total wave plate of the transmission, which is effecting other areas of the care. Now I'm being told that my transmission was a lemon-make. That it was built faulty & GMC knows it. They have had thousands of complaints and refuse to recall this transmission. This is totally unfair. I still owe 18,000 on this truck. I'm paying two mortgages and I'm worried about how I will make it to work the next day. The maker of this truck should be held responsible for the faults not the consumer. Do to this issue gm issued an exchange program but the dealer ships won't engage in this. Please assist me with this issue.

Vehicle is hard shifting from 1st to 2nd gear. Had serviced with new transmission fluid on 7/2/13. On 7/5/13 vehicle would no longer shift at all while traveling on the freeway on our way to family vacation to hilton head SC. It was towed to parks Chevrolet in charlotte, nc where transmission was disassembled with parts replaced and rebuilt. Upon departure of pickup vehicle is still shifting hard from 1st to 2nd gear (around 20-25mph) and we hope to make back home to ohio safely. I've researched this issue is common in GMC Acadias. Issues needs addressed and resolved for safety! I will be returning the vehicle to chevy dealer when we return home for further service. We have already paid the warranty deductible and hope to not incur more expenses!.

As I was taking a family trip, I was traveling through some steeper grades when the vehicle rpm¿s were registering very high and would not shift to lower gears even when my travel speed slowed down. On my display a warning came on saying to ¿idle the vehicle transmission hot� I then pulled over in a very busy road and let the vehicle idle for 10 min it then shut off but had very weird driving characteristic the rest of the way. This included when shifting from second gear to third it felt like the clutch would pop and jerk the vehicle when it did shift. Thankfully as we got closer to a town the vehicle engine light came on and we immediately contact onstar and they gave us the codes all relating to the vehicle wave plate failure. I then had to take it to a dealer out in the town we were visiting at the time which was a major headache. This was very disappointing considering the vehicle barley had over 50,000 miles and GMC is supposed to be a upgrade for gm. Shame on them for not recalling all 2007-2009 models to repair this issue. Needless to say gm did offer to help with repair cost only cause they know it¿s a know issue which I appreciate but the fact is with that low of miles on the vehicle that should have never happened in the first place.

The contact owns a 2007 GMC Acadia. The contact stated that while driving 50 mph, the check engine lamp illuminated as the vehicle failed to accelerate. The vehicle was not repaired or diagnosed. The manufacturer was made aware of the failure. The approximate failure mileage was 75,000 and the current mileage was 75,749.

The vehicle first started fine, however, could not shift into reverse. Once starting and turning the vehicle off three times, it finally shifted into reverse. Then on the highway going to drop off my kids at school, the vehicle then would not shift higher then second gear. Each time I stepped onto the gas pedal, the rpm's would go up, but the vehicle would not go any faster then about 30 mph. Of course, this situation is hightly unsafe, especially with small children in the vehicle. At one point when I was able to drive my vehicle, and everyone said it was fixed, I drove 3. 5 hours to pick up my step-daughter and was left stranded there, due to the same issue it went in for the first three times. It has been in and out 9mostly in) the shop for over three and a half months, with each replacement part for the transmission, it goes on a test drive and the same thing keeps happening.

The contact owns a 2007 GMC Acadia. The contact stated that while driving 45 mph, the contact heard rattling from the front end and noticed a burning oil smell. The vehicle was inspected by a mechanic, who stated that four of the drive-shaft bolts were missing and two were bent. The vehicle was then taken to a dealer but they were unable to determine the cause for the failure. The failure was reported to the manufacturer. The failure and current mileage was 95,000.

Powertrain (transmission) gave - out at 72100 miles on my 2007 GMC Acadia and GMC dealer stating "move plate" and "controlled module" and estimates are at $4000. 00. I have read many complaints online about this issue and it should be mention on NHTSA and have GMC make a recall.

We bought this car used. Had it for less than a year and only put 8,000 miles on it. On a return business trip the transmission went out while going down the interstate. Had to call for a tow and have had the worst experiences with the dealerships working on it. I'm absolutely over this GMC and the junky car they created in the Acadia.

On this particular day I was merging on to the freeway (which speeds of other traffic was upwards of 65 mph). I attempted to accelerate and in doing so was unable to switch gears. The vehicle "bogged down" and nearly caused an accident as I wasn't gaining speed. This issue repeatedly happened on my way home, traveling a distance of 60 miles. This malfunction according to some discussions on edmunds is well known by gm! it needs to be more than fixed, the transmissions need replacement. A bandaid isn't going to work in this case.

Car will not accelerate, engine just revs and rpms increase to 5000+ when attampting to change from third to fourth gear. Thankfully, I was on a road less traveled and did not get smashed in the back with my son in the back seat on the highway. What a safety hazard!.

Would not go into reverse, would not exceed 20 mph in drive, rpm's spiked to 4000, check engine light comes on, irratic driving because of the condition, web search reveals numerous incidents of same type involving breaking wave plate failure.

The contact owns a 2007 GMC Acadia. The contact stated that the vehicle would not accelerate over 40 mph. In addition, the gear shifter could not be moved into reverse. The check engine warning light was also illuminated. The vehicle was taken to dealer for inspection and the contact was advised that the transmission needed to be replaced. The transmission was replaced. The manufacturer was not made aware of failure. The failure and current mileage was 87,400.

Bought with 58k miles on it, 9/2012. Problems began the following April. Sitting at red lights, the truck would stall out at acceleration, occasionally not restarting immediately. Dealers couldn't replicate problem. Problem briefly stopped, and now it has returned and is far worse. While driving, it shakes and jerks like a new driver learning to use a manual transmission. Several times the truck has shut off completely on highways while cruising at or around 70mph or accelerating to pass someone, nearly causing accidents. This truck has been towed home 3 times this month from this issue, I refused to take it to a GMC dealer because I can't keep paying $109 for diagnosis and they say they don't find anything (twice already). I recently had the vehicle scanned independently and it's given me codes 7ea and 7e8. The second code doesn't give a diagnosis. In the last week it has failed to start 4 times and I've been keeping video blogs to record what it is or isn't doing. It is currently sitting in my drive way, not operable. Gm customer service says there isn't enough evidence to support a recall, but everyone is having the same problems. Twice it stranded my wife and children on interstates. On 10/30/13 (on our anniversary, out of town none the less) it shut off and we had to get pushed to the shoulder. . . Very embarrassing! something must be done! everybody can't be telling the same lie! also, the "service airbags" notice just started showing.

There is a problem with the transmission on these vehicles. I was told so by the technician that replaced mine. Our transmission gave out and left my wife and child stranded on the side of the road. The tech who worked on my vehicle said that the wave plate in this transmission blows apart. The ones that are being issued to rebuild are better. If there is an issue with these transmissions leaving people on the side of the road why hasn't there been a recall?.

After spending $370. 51 at my local GMC dealer for stabilitrak errors resulting in low fuel input into the engine, with a maximum speed allowable at 35 mph, my 2007 GMC Acadia is once again experiencing stabilitrak errors. They generally occur when I roll to a stop at a stopsign or stoplight, but I am very concerned that the transmission will reduce speed when I travel the interstate. My local GMC dealer claimed this problem was caused by a "cam exhaust position sensor fault" and replaced the "cam exhaust position sensor" on 3-20-13 for $370. 51. For one week this repair worked and there were no stabilitrak errors. Ten days later, my 2007 GMC Acadia fwd is worse than ever, endangering me at night by shifting suddenly into "stabilitrak error, low fuel input" mode. I am terrified that my GMC dealer will charge me more money to pretend-fix this problem, as they have me coming in for $400-$1,100 repairs every other month now since they want to sell me a new car.

No previous symptoms. Could not get the vehicle to go in reverse. Got towed to the dealer. Diagnosis - wave plate fracture. Found many many 2007 GMC Acadia's had this problem, there should have been a recall. This happened 1 year after the warranty expired, but only 74419 miles, and never driven in extreme conditions and never towed.

I was driving to the store, going down hill on the right side of the road. Mid-way down a message appeared on the computer saying "engine failure, power off" and the car just shut down with out warning. No matter how hard I pressed on the gas the car was shut off. The steering went out as well and I had to stand in the seat to use all my power to turn the wheel. Previous to this, the check engine light had not been on, no advance warning of this. I had both of my children in the car at the time. Luckily there was a bp gas station with garage at the bottom of the hill, I was able to coast the car into the gas station where they ran diagnostic testing and repaired my car and reset the sensors. Nine months later I was driving with both of my children again, in north east washington DC when out of no where the same message appeared. I was able to pull the car over to the side of the road and restart the engine one time. I turned around to go home and on the drive home the same thing happened on a less of an incline of a hill. The car shut down completely towards the top of the hill going down. Same as before, no gas and no steering ability. I was too scared to leave the car on the side as cars coming over the hill would not have time to stop before hitting us. I put the car in neutral and tried to glide down the hill to the shell station. The car cut out completely and lost all momentum so I had to push the car into the gas station and wait 3 hours for the tow truck to arrive. It went back to the bp station from February and had a new battery and several other items replaced. I bought this car new in 2007 and have had countless breakdowns and replacements- two transmissions within the first 3 years and repairs. I keep up with car maintenance regularly and do no neglect anything.

Trans went out shortly after purchase, alternator went out shortly after purchase, needed new wave plate, needed new alternator, sun roofs leak water through the interior lighting and down both a-posts. Continues to run after shut off and key removed. Slips gears, will not upshift.
