Acadia 6-cyl

  • 71,500 miles


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!

The transmission on our '07 Acadia went out after only 67,000 miles. We had to pay over $3,000 out of our own pockets to get it repaired because it was over the five year warranty period even though it was still well under the mileage limit. When you pay over $30,000 for a vehicle you expect it to last longer than ours did without having to pay thousands more to keep it operational. A few months after getting the drive train repaired we are experiencing camshaft/crankshaft issues. The vehicle is functioning at about 60% of its original power. We can only assume that this will entail another costly repair.

Engine light on vehicle, the vehicle will not shift into gear - happened three times had to pull off side of road to not get hit from other vehicles and 5 year old was also in car with me. Had to shut off the car multiple times to get started again and for it to finally shift into gears. Took car to dealer and they replaced transmission control module valve. On 4/1/13 car would not go into reverse on incline. Had to drive forward and reverse on flat area, dealer now says they found broken wave plate and burned 3-5 reverse clutch. Also found internal defect park of valve body. Car is only 5 years old and has only 55 thousand miles on it. Saw other issues on this database all with broken wave plates on 07 Acadias. Paid thousands of dollars to get this fixed.

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.

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.

No recall for defective transmissions? bought 2007 acadiar used, 2600 miles /felt transmission problems early on. Very noticeable jerk at 40mph. In and out of dealership since. Last few months car has been in to dealer frequently re car bucking at stop lights really rough thought engine going to die. Every time nothing showed in codes, emergency trip to doctor/heavy traffic main artery/can't get over 20mph/engine screaming/ make it to dr. (omg) towed to dealership. Transmission gone. I could have had a serious accident. Finally heard something about a wave plate. For 5 yrs I've said something wrong. No one said these were constant problems with Acadias. They issued recalls for a leak in the sun roof. No recall for defective transmissions" known defective wave plates" I have extended warranty, but many don't. warranty or not, this safety hazard should be fixed by GMC at their expense. A recall is mandated. Just ask the owners...

I was driving my car when all of a sudden it wouldn't accelerate above (20mph?). I was forced to park it at an apartment complex and get it towed to the dealer. Now less than 6 months after paying out of pocket for that repair, I am having the same problem.

Started shifting weird, then RPM's would spike as car was shifting. Car then would not go into any gear and left stranded on side of road. Had to have vehicle towed to dealership where it was found to have a broken wave plate, damaging numerous gears and torque converter. Pressure control module which is part of the valve body was bad. Had to replace entire transmission, all seals, gaskets. Also found out when replacing that the thermostat housing was leaking coolant, so had to have that replaced at same time. This at a cost to us of over $3500. Have read online that this is a very common issue with this vehicle. We were 7 months out of our 5 year/100,000 mile warranty and GM would not help in the least.

I have owned this car for about a year and since I have owned it have had nothing but problems. First the struts were blown, the dash lights would go from bright to dim, the steering wheel made a clicking noise, the windows leak...this car only has 41,000 miles I mean come on! now the transmission has completely failed and after reading other websites it sounds like I will be paying $4,000 dollars. I am a new mom and have 3 step kids. I can't feel safe in my car because I'm worried about it breaking down constantly. Now I have to dump all this money that I don't have into it. I really just want to cut my losses, but is that really the best thing to do? I'm stuck with this junker car and I couldn't feel more sorry for all these other people having the same issues. I'm absolutely miserable. Thanks GMC you suck.

Vehicle has about 50,000 miles but a few months out of warranty and started giving me problem shifting gear. Researched the problem and found a lot of similar complaints out there but GM is refusing to take responsibility and making owners pay to fix the problem. Transmission is defective.

Prior to having the transmission break down the vehicle had been shifting hard from 2nd gear to 3rd gear. Starting up a small grade from a stand still the transmission suddenly began slipping at about 20mph. The vehicle would not shift and the engine light came on. I was only about 1 mile from home so I drove it home at about 25mph. At home I put it in reverse and it would not go into reverse. Took it to a transmission shop the next day, they called me back later that day and told me it needed a new transmission. They are doing the job for $3200.

3 months past the 5 year 100K warranty with only 55000 miles on the car and both the water pump and transmission went out. GM paid for half of the costs still $1253.05 out of pocket when it should all have been covered. This is a consistent problem with the Acadia and GM knows it but refuses to step up. The day the transmission went out we almost got thrown through the windshield definitely a safety issue.

I bought this vehicle June 2012. I started having transmission problems last week. The transmission would stick when stepping on the gas or when going in reverse into my garage. I found over 200 complaints about the transmission. This should be a recall item. I was driving on the highway trying to get up a hill when the car started to do this. I luckily was not far from my exit and made it to a gas station when the car just stopped.

  • 64,000 miles
The vehicle would not shift out of 2nd gear going down the highway. The check engine light came on, and there are now four codes all for internal transmission issues. The car is 4 months past the 5 year warranty, but only 64000 miles. This is a huge safety issue. If this transmission fails while on an interstate highway, and it will not go over 20 mph, the results could be deadly. By researching this issue I have found a considerable amount of complaints about 2007 GMC Acadias between 50000 and 80000 miles having transmission failures, but yet no recalls. This is an issue that GMC is well aware of, through their own admissions. Why is there such a delay waiting for a recall" are all of the complaints going to have to wait for a fatality before GMC admits there needs to be corrective actions"

The car has had electrical and engine problems since we purchased it due to water leaks from a flawed sunroof design. Even after a recall to fix the sunroof to prevent water leaks; it continues to leak and damage electrical and engine systems. This is an ongoing problem and is a widespread concern for the 2007-2008 GMC Acadias. I would like someone to investigate this problem. I believe it is a safety concern because the leaks occur in the area where there are airbags. I think there is a structural defect that may not be able to be repaired and it presents a safety hazard for all who drive these vehicles. Please investigate this problem. Do not let GMC sweep this under the rug!

While traveling at 45 mph, and with no warning (weird shifting, etc) the transmission completely failed. After being lied to by the dealership and GM, I did my own research and found that this is a common problem with this model year, so much so that GM has created a special program to fund part of the repair if the vehicle is out of warranty. (wave plate failure in the transmission). This vehicle should be recalled with a mandatory replacement of the wave plate.
