The passenger sensing system is not working properly. Sometimes it will indicate that it is on and other times it will indicate that it is off even when someone who weighs over 140 pounds sits on the passenger seat. It won't indicate that the person doesn't have their seatbelt on. Even if driving and person has been sitting, it won't turn on. If an accident occurs the airbags will not go off because it doesn't sense correctly.

When first starting engine a loud pop would occur. Signals, clock, stereo, dome light, battery gauge stopped working. Chevrolet dealer replaced the stereo and amplifier ($1500 ). then if I left Acadia in the rain I would find a small puddle of water on the floor under the emergency brake and a drop of water on the air bag on the driver side in front of the vehicle. Was told it could be the sun roof tubes were blocked so I took it to the auto glass place and had the tubes cleaned out. Very concerned about the water because I do not want to loose power in vehicle again. Just went on a trip and had to park outside in parking area and had a real puddle on my mat and underneath the mat. Today I called an auto windshield repair shop to see if the windshield could be leaking and was told that if the car was not in an accident or if it has not had the windshield replaced, they didn't think it would be the windshield leaking, that GM was good about installing and sealing the windshield. My car is kept in the garage and I am the only driver. It has never been in an accident and I am afraid that the wiring will short out, cause a soft spot in the floor, or start a fire. This automobile has only 69,285 miles and has been very well taken care of by only General Motors dealerships. Serious problem involving wet elements and electrical problems here. Please let me know what to do!

In 2011, our Acadia electrical system started to malfunction. First the driver's side headlight wiring burnt. We had that replaced. After the headlight, we started noticing the engine light was coming on and the air bag sensor was notifying us that the air bags will not deploy. None of the sounds where coming on in the car. For example, if you were not wearing your seatbelt the "dinging" did not happen. I took the Acadia in for service and they told me it was my cell phone that triggered the defect. I thank god I was not in an accident however if GMC knew of the defects why not be up front with us. My family and I travel plenty. Safety is the number one concern, we bought the Acadia faithfully and hopes GMC provides the best service possible.

Airbag seat connectors and airbag replaced after service airbag light came on. This should have been included in the 2008 GMC Acadia recall #102606/GM #14030 and for some reason this particular vehicle was not. This recall needs to be expanded to all 2008 GMC Acadias!!

In light of the all the safety recalls by GM for ignition switch failures, I believe that my wife's crash in our 2008 GMC Acadia was the direct cause of the ignition switch failing. Driving North bound on AZ route 89 in the area of prescott, AZ called the granite dells, the car proceeded straight where the road turns slightly to the right. The cat proceeded into and partially up a granite stone out cropping on the opposite side of the road. The car then went air borne landing up side down on its roof in the middle of route 89. I believe that this accident happened due to ignition switch failure which in turn shut off the engine, power steering, and the entire air bag system which in this accident fail to deploy. My wife was air lifted to northern Arizona medical center in flagstaff, AZ for sever head injure from which she has recovered. It is my belief that the ignition failures that have shown up on other GM cars is also a problem for the 2008 GMC Acadia and possibly other like models of GM vehicles. In my opinion it has to be ignition switch failure that shut down the engine, power steering and air bag system causing this accident.

For several months, the front passenger air bag warning light would illuminate, and the message center would display 'check air bag'. two weeks ago, it became not intermittent, but constant. I took the car to my GMC dealer and was told $735 repair - air bag passenger pressure module needs replacing. There are hundreds (if not thousands) of the same problem reported on various internet site, blogs etc. GM has a supplier problem with this part, and it needs to be investigated. I purchased this vehicle new and have countless problems with this vehicle.

TPMS is inoperable light always on 4. seats are composed of polyurethane molded foam causing an array of health issues for myself and 2 children as car gets extremely hot 5. brakes engage during high speeds randomly causing car to slide 6. heavy metals/air plane parts found in many places of car 7. fumes inside constantly improperly routed fuel/emission system? 8. transmitters, ignition will not turn over unless fm transmitter in key is attached, should not be a hybrid or grid operated vehicle. Spray foam and welded metal composed much of vehicle. Medical white packing in much of gaps with a contaminated smell 9. lots of money trying to repair damage, owner filed bankruptcy lots of medical bills. Dealers and manufacturer do nothing, I have wrote letters and many phone calls. 10. microwave effect on anyone in car along with magnetic pulls. I myself have had this car since Feb 2011. I have lost some nerve function on left side of my body leaving me with multiple scars for life down left side of body and center forehead resembling radiation burns but I never underwent radiation. I lost my hair in 2012 along with joint damages. Please do something, I am not an experiment and never agreed to be one!

While sitting in the passenger seat, the passenger airbag light will come on, noting that the airbag is no longer activated. A message will also come up on the driver's messaging screen stating to service airbag. When the vehicle was brought in, I was told that I needed a new software module for my vehicle. I was told that there is a chance that if we were in an accident the passenger airbags would not deploy. I find it hard to believe that a 5-6 year old vehicle should already need its airbag module replaced.

Approximately the first of November 2013, I had picked up my mom to go shopping with me and I very seldom have a passenger with me and happen to look up and notice the light on the airbag light that says on or off was off !!! she weighs about 135# and so I noticed we went into the store and came out and it then registered on!!! so I watched this for the next few weeks and it continued!! sometimes on and sometimes off! so when I went in for an oil change at bergstroms I had them check it out and they said it could be corrosion on the plugs under the seat but that wasn't the problem! so they said with a big man in it registered like an infant sitting there! said it would cost $800 to replace it!!! this car is in like new condition and I do not have a daily passenger! I'm thinking that may have been defective since day one!!! thank god I didn't get in a collision and lose a loved one ! this would be a huge lawsuit!!!! I am gonna see if GMC will pay for this fix! any other questions call me at[xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Acadia 6-cyl

While driving the car, I felt water drip from overhead and heard sloshing noises. Shortly thereafter, water began leaking from airbag indicia. Though the vehicle was turned off and key removed, the engine continued to run. Imagine how unsafe to turn off a vehicle, remove the key and the engine to remain running. Before I could get to service, the temperature plummeted to below zero, and I could not get the defroster to work. I scraped the interior of the windows, but without heat, fogged again. Zero visibility. The dealer said there were multiple points where water was seeping into the car, wreaking havoc with the electrical system, including HVAC, defroster. Service tech said there was "blower mower" failure. After some research, I discovered my vehicle had same problems as GMC Acadia campaign 08207, with failure of sunroof part 25930220, which affected limited VIN numbers. We also discovered the airbags are not working from the water damage to the electrical system. The current status of this getting repaired is unknown -- obvious safety concerns! in addition, I had noticed floor mats being damp, but assumed a consequence of the snow and rain. I am convinced that the leak/damp floor mats is reason for the mildew/mold smell. Each of these problems are well documented in their tsbs. I was also shocked to find so many similar complaints! please, please review the correlation between tsbs electrical system failures and repairs to the leaking hose. Of course, GMC denies this is their problem, and says repairs will all be at my expense. Finally, I am not the first person to have this problem! surely, the fact that I (and many, many others) are having the exact leak problems as referenced in GMC campaign 08207 indicates that problem went beyond those VIN#S. they are hiding a big problem. Help!!

I have had problems with this car for the last 5 years. First the airbag light came on when we were going on vacation I took it to the dealer and was told it was fixed but it kept coming on and off took it again and same thing happened it kept doing that so I took it to the dealer and they said they had to reroute the airbag harness to fix the problem. Again it only lasted for a few weeks and it came back on. By that time the car was over 60,000 miles and it was past the extended warranty so I'm stuck with that problem. The transmission had to be repaired a few months ago and it needs to be repaired again but don't have money to fix it and GMC won't recall the 2007 and 2008 Acadias knowing that the Acadias of those 2 years were made with a faulty transmission and a lot of people are having problems with them. They fixed the problem for the 2009 and later models but won't do anything about the 2007 and 2008 models and a lot of people don't have money to pay for a very expensive repair that is GM's fault. My Acadia is sitting on my driveway because I don't have money to fix itand I'm stuck using a 16 year old car that is more reliable that our new car. I have had the following problems since a few months after I purchased what I thought it was a good and reliable family vehicle. Air bags light on and never got fixed suspension repaired about 3 years ago lighting problems a couple of times and now there is a recall for that transmission problems for the last 6 months the car has only 70,000 miles and it should not be having all this issues please look in to this I know there is a lot of people having the same problem and GM won't do anything to fix the problem. They knew they had a problem with the transmission's the 2007 and 2008 models that's why they fixed the problem for the 2009 and later models. Please do something about it. Thanks.
