Service airbag light illuminated in the dash; technical service bulletin available to dealer for similar issue only covers the airbag connector not the airbag module, which has gone out in this vehicle, on the passenger side. I have discussed with dealer and GM and they are unwilling to repair this safety issue. This appears to be a common defect in the 2007, 2008 GMC Acadia as well as the Buick enclave and early Chevy traverse. A simple internet review will show multiple complaints. GM is unwilling to recall these vehicles for this part which would be the proper customer care but instead will complain here for review. A review of the number of vehicles affected by this safety issue is needed.

I bought this vehical from our local GMC dealorship and two weeks after driving away from the lot, the front air light indicated that the passenger side air was not active even with a person sitting in the seat. I contacted the dealorship and they said they I would have to pay $800 to fix this item. Keep in mind, I just bought this vehical from them and did a quick google search and this appears to be a common problem with this model vehical yet not recalls have been issued. My wife was 8 months pregnant at the time and refused to ride in the vehical until I got it fixed. We are also having transmission issues which appears to happening to 100's of thousands of other Acadia owners. Why has this vehical not been recalled yet? I dont understand how they can get away with selling these items knowing that there are so many safety issues with them.

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.

We purchased a used 07 GMC Acadia from a local dealership and the airbag light kept going on and off by itself. I asked the dealer to check the recall list for our vehicle, however they stated all the recalls had been done. We had to pay $500 to fix the problem.

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.

The contact owns a 2007 GMC Acadia. The vehicle was being driven 50 mph when the driver crashed head-on with another vehicle. The air bags did not deploy and the driver sustained injuries to the left leg and head. The police reported to the scene and a report was filed. The vehicle was towed to a body shop where the body damage was repaired. The manufacturer was contacted and the contact was informed that an investigator would inspect the vehicle. The inspector stated that the control module was unplugged during the impact, which caused the failure. The approximate failure mileage was 47,000. Updated 2/8/12

Vehicle is a 2007 GMC Acadia. The passenger side airbag turns off when there is a person sitting in the seat whenever they move. Sometimes the airbag remains off for 10 to 15 minutes. The vehicle was taken to the dealer and was diagnosed as a bad occupancy module and loop connector. There is already a recall for these issues, however my VIN number is not included in the recall. After talking to GMC, they said that there was nothing they could do and I should pay the $1700 to correct the problem and hope that I get reimbursed at a later date.

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.

While completing a right turn from a complete stop I rode up on a curb and all curtain air bags deployed. There is no physical damage to car exterior, tires, rims and undercarriage. Damage assessment has been confirmed by two GMC dealerships and my insurance company. I have asked GMC to provide information referencing whether or not the sensors and computer performed per design. The only answer I have received is that the yaw sensor is what triggered the deployment, that all bags where deployed and this is not a manufacturer defect but an insurance claim. To my knowledge no analysis has been done to determine speed, angle etc... my wife and two children where in the vehicle when this occurred. We are so confident that the vehicle malfunctioned that unless we are reassured that GM has resolved the issue we will not drive the vehicle any longer.
