  • 60,000 miles


The car has leaked since we bought it. We have had it in the shop several time at the place we bought it and it continues to leak. Recently, the leak has started to affect the electrical workings of the car. The florr has been saturated with water and when approaching a stop, water will pour from the ceiling, soaking the driver and rear poassengers. The water will run down the inisde of the windshiled which impacts visibility.

Acadia 4-cyl

  • 64,000 miles


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.

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.

Due to installation of a factory defect part in the air conditioning system the water collection drainage system for the evaporator becomes plugged from the inside. This in turn dumps water onto electrical components of the vehicle including the blower motor and wiring harness that is located under the passenger floor. It is a non serviceable issue that required complete tear down and factory replacement parts to correct. It is a fairly common issue with the 2008 model and the newer models all come equipped with an air cleaner in the ac ducting to prevent the problem.

The vehicle has two problems. The radio works, but there is no sound for the back up warning, turn signals or radio. This problem occurs in the GMC Acadia, Chevrolet traverse and the Buick enclave. The problem is likely the premature failure of the BCM or the amp. When driven in the rain, the power steering fails momentarily and it is very difficult to control the vehicle.

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.

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.

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!

We were driving and smelled a burning smell coming from the drivers door. The drivers side windows switch, door lock switch would not work. We took it to our mechanic and he determined that the drivers side switch had burned up and melted to the door wiring harness. The switch and harness both had to be replaced.

Vehicle has been serviced 4 times for water leak that dealer can not find. Water that has leaked inside has caused a malfunction in the fuse block. This caused all lights, including headlights to flicker and gauges to read wrong information. Very dangerous and distracting when driving. Could lead to more serious electrical problems if water continues to leak in.

For quite some time, the front right air bag sensor does not sense that there is a passenger sitting in the front right seat. We have had the sensor checked repeatedly at the dealer, and they have not been able to replicate the problem (saying everything is fine). The passengers typically are our children, both of whom are 5'9" tall and weigh 120 to 125 pounds. We usually have to stop the car, turn the car off and then on, and then it works. This past week, the sensor was flashing, and we got a related "service air bag" light on the dashboard. We took it in to the dealer, and have been told it is a $1,000 repair to replace the front right passenger sensor module. This after we have had this item checked multiple times (and have been told that there has been nothing wrong with it), and, after a full extended warranty on the car (which included air bags) has expired. There has been a recall for 2007 GMC Acadias for improper sensors, but our car was not included in the recall. In 'googling' this issue on the internet, we see several complaints on official car sites like edmunds, stating a similar problem for other Acadias. We believe that GMC has known that it has had faulty sensors on their 2007 GMC Acadia models, but did not make their 2007 recall comprehensive enough. We would like for the nhtsb to investigate with GMC how many other 2007 GMC Acadias have been serviced for similar problems. Our car has never been involved in any vehicle crash or accident.

I experienced water leaking and running down the inside of both of the front doors. In addition, the dash lights faded in and out intermittently, the clock loses time, the nav and radio screen blacks out, and the stability trak service light comes on. They "fixed" the water leak by extending the drain hoses on the sunroof. All of the electrical problems were found to be related to the leaks in the sunroof. On Sept. 18the of the same year, I returned the vehicle to have a recall on the sunroof drains performed. I advised that I was still having the same electrical issues. A dimmer switch was ordered. On Feb. 20, 2012 I started my vehicle and heard a faint pinging noise like a dying smoke alarm emitting from the passenger dash area. I took it to a GMC center and was told that water had leaked behind the dash, causing corrosion and a short in the ip fuse box. I had to pay almost $1,000 to have the leak sealed (design flaw) and had to have a new electrical block installed. I called and complained to GM that I should not have to pay for damage that resulted from 1) a poor design and 2) damage that should not have happened since I had taken the vehicle in twice on prior leaks which were supposed to have been fixed. It has been three weeks and I am still getting the run around from GM. Now they claim it wasn't the sunroof leaking, but the door. A leak is a leak and it should have been checked on the prior service visits. Apparently the leaking has been going on for quite sometime. I see that others have had this same bad experience. Here we bailed out a company that won't back up its product.

I am on active duty an active duty military member. While attending a military school, I purchased a new 2007 GMC Acadia from a GMC dealership nearby. After the course, I served a year at a military station in another state, while there, my vehicle was serviced twice for recalls by a GMC service center nearby. One of the recalls was to fix a defect in the sun roof that was causing water leaks. I had the vehicle serviced in 09 while the vehicle was still under warranty just before shipping for a 2 year overseas assignment. At that time, I identified some electrical issues. Soon after my arrival to my overseas assignment, more electrical issues developed along with mystery water leaks that were saturating the carpet and causing mold to grow inside the vehicle. There was no GM service center in that country so I had to live with the leaks and electrical problems. Finally after about a year, I had a minor accident where my tire hit a guard rail doing about 10 mph. All the air bags deployed but there was no other damage to the vehicle. At this point I quit using the vehicle. The seat belts didn't work, the ac and heater didn't work, the left blinker didn't work, the engine would not shut off with the key, the battery box behind the passenger seat kept flooding with water and I had to disconnect a battery cable every time I parked the car to keep the battery from dying. The vehicle was unsafe. I am now stationed in the us and have shipped the vehicle back to the usa. I am now trying to resolve all these issues with a local GM service center but I am being told by that service center that the vehicle is basically totaled with only 60K miles but since it is now out of warranty, I am responsible for the repairs.
