I was traveling at approx 40 MPH in town, the vehicle felt like it bogged down, odometer still showed 40mph but I was not going anywhere, car behind me slammed on their brakes, car behind him slammed on their brakes, I was honked at all the while I am pushing on the accelerator, after 10 or 12 seconds it went forward with the RPM's going very high and MPH went to 50 and back to 40 immediately and I went forward. It scares me to drive this car and from what I have read just today, I am not the only one having the problem. Please do something about this before someone is really hurt.
2007 GMC Acadia acceleration complaints
Page 2 of 2: complaints 11 to 19 of 19, newest first, as owners wrote them.
My car would not go over 40 MPH on a highway and the rpms were shooting up to 9,000. I safely made it to a parking lot and when I went to leave the car would not move in reverse! I had to push the car, with my 5 children in it, out of the spot!! (I'm a tough chick but this was crazy!). I got the car out of the lot and was able to slowly make it home. My car is only 10 months past warranty and we will be stuck with a big bill. I think it should be covered or gmc should reimburse the repair fee.
On monday, with my children in the car, I started noticing that the car was not shifting correctly. I did not think much about it. Then on the wed of that week as I was driving in a major city downtown area for the morning commute, the engine light came on... I was at a stop tried to accelerate and the RPM's revved. Stepped on the gas and the car would only go 1 to 2 miles an hour then speed up ... Dealer said that there were "many parts in the pan" and that I needed to have transmission replaced. $3600 plus tax or have it rebuilt $3300 plus tax. Called gm after reading the various post on edmunds about the acadia problems. They were very nice and opened a claim but as of yet, no one ever called me back. When they opened the claim they said someone would be in touch within 2 business days (and they would see what they could do on saving me some money on the bill) as I was due back at the dealership to pick up my car.
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.
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.
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.
Going down highway and transmission started acting up. Couldn't go over 25 MPH and had no reverse. Had new transmission put in and that did not fix the problem.
Tl* the contact owns a 2007 gmc acadia. The contact was attempting to park the vehicle 1 MPH with steady pressure to the brake pedal when the vehicle abnormally accelerated and crashed into a building. The contact engaged the brakes harder but the vehicle would not stop. The air bags did not deploy. A police report was available. The contact stated that there were damages to the front end of her vehicle and to the building. The failure and current mileage was 35,000.
When we were looking at the gmc acadia and going out for a test drive, we mentioned to the sales rep that the acceleration was very sluggish. He responded that it takes mileage to warm the vehicle up. We have 15,000 miles on the vehicle and it still is sluggish. We have brought the vehicle back to the dealership 4 times to resolve this issue. Driving in the rain and/or snow is very hazardous, and going up hills, since it lacks acceleration, it causes the tires to spin out. We have gotten stuck going up a hill in rainy and/or snowy conditions. This is very dangerous and needs to be fixed once and for all.
