Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: Ahh, the ole' sophomore slump. The 2008 Acadia suffers from widespread transmission failure around 75,000 miles.

I own a 2008 GMC Acadia I have had it used since Jan 2015 I have had it in dealership almost every 3 months since I bought it. I was recently driving and had a fire in the passenger heated seat where my daughter was sitting and it burned a small hole in her jeans so far GMC is checking to see if its a defective equipment failure or not? in the mean time my sunroof has quit working and now my roof is leaking and my car smells like mold. The whole electrical system is going crazy with flashes of interior lights. I also had the vehicle stop on me in the middle of parking and found out the power steering pump needed to be replaced. They need to have a recall on these vehicles because our children ride with us and they are unsafe especially now that her jeans are burned and she has a small pink spot from the heated seat. The dealership told me today likely the seat wont be replaced and if its not I will be contacting me a lawyer. My children S safety come first. Hopefully the will also do a recall on the electrical equipment and the sunroof leaking because our vehicles are not safe after water gets onto all the electrical devices and shorts out and may cause a fire next.

Electrical system is completely dead. Key cannot be removed from ignition. This happened earlier today for a short time. Electrical did come back on allowing the vehicle to be driven home. When shut off, vehicle's electrical system is totally dead. Shifter cannot be taken out of park. Key cannot be removed. This vehicle has had previous issues with water from sun roof leaking into cabin, possibly contributing. Transmission recently repaired. Internal switch module replaced. Audio amp recently replaced, totally inop.

My 2008 GMC Acadia leaks when it rains, the floor boards fill with water & water comes through the interior lights causing them to shorten, blink. The power windows got stuck wouldn't go down almost smashed my kids hand. The worse part driving on interstate at 65-70 traffic slows to 40 and your vehicle doesn't go almost causing the worse accident ever. Seems this wave plate, shift solenoid is a manufacturer defect especially since I was only a few months after initial purchase and the truck was returned to dealer for same issue so that means the transmission they replaced the bad one with was so bad or reached its time out mileage. This should be a recall if it happened shortly after purchase (purchased used) then it happens again with the replacement transmission and all the threads in have read every owner is experiencing this, someone will have bad accident possibly death. Does death have to occur for us to get better resolve and make GMC take care of this. Over $5,000 was tough to christmas time

The airbag on/off lights would both light up at the same time so you didn't know if it was functioning properly. The warning "service airbag" came on. This was while driving any speed, any type road, also while the car was in park. Key would not come out of ignition, the engine would turn off but electrical would still be working. Also the power saver mode kicked in and we had to have the vehicle jumped.

Sunroof continues to leak water. Moisture mildew growth in interior. Car gets saturated every time. Driver side floor boards full of water. Electrical warning lights continue to sound and it's the brake warning. Water is corroding my electrical's not safe! GMC keep ignoring this problem, even though this issue is an epidemic of complaints all over the web! this should have been a recall years ago! this is absolutely unacceptable!

Rain leak into car, water pouring into frame and trapped in frame of car, roof of car. Water leaking out of airbag locations. When we drive, we can hear water moving around in frame, see water leaking out of airbag areas in frame of car. Water trapped inside frame of car, rotting inside of car, mold, mildew potential, fire hazard. GMC says they are not responsible for repairs, car no longer under warranty. How can I safely drive a vehicle in which both the airbags and electrical system is compromised??

Car would not start and had to jump off. When I did this I went to turn off and had the key out and the car kept running for around a minute before finally stalling. Did this several times with the same result. I then took it to dealership. After a day they called and informed me that the windshield was allowing water in at the passenger side and fuse panel under glove box was full of water and corroded. They advised a new windshield as mine had a small star crack in it and needed to be resealed. That along with recommending a new fuse panel. They checked all drain lines for sunroof and said they were fine. Paid the bill for this at $799.58 with assurance that water issue was fixed. Well one week later and the first rain since after sitting in light rain for 2 hours and driving 20 minutes I noticed water dripping into both floorboards from a post. I will be taking back to dealership tomorrow with them still not aknowledging anything about water problems.

I purchased this vehicle, and was told there were no active recalls and nothing wrong with vehicle, the dealership supposedly had took it through a hundred point inspection, immediately, the air bag light came on, it started losing anti-freeze and the check engine light came on, after several trips to the service dept at this Toyota dealership, I am still having issues, they fixed the small things like the water pump, the rear wiper blade, electrical but the engine light still comes on and I had it checked out and it is the transmission, it is going out, and the air bag (service air bag soon) is still on, but was supposedly fixed by a recall in 2011, either it was a bad part, or it was not serviced at all. I have been driving for 40 years and I have always been a loyal GM owner, especially the Buick lasabre which I drove for 15 years, but I am not happy with the quality of this vehicle and the dealership that I purchased it at, and they are rated by the BBB as a. I also do not like the fact that on GM commercials it states non GM owners, like come on in, we will take care of non GM owners but not the loyal ones. I think it very important to stick with american brands and love GM, just very dissatisfied with this one. I think GM should fix this car, the air bag and especially the transmission!!!!updated 11/10/15

Nothing in the car will make sound anymore. The door chimes don't work, the backup sensor does not sound, turn signals don't make sound and the radio is on but does not sound. I had to reset to factory settings and it still makes no sound.

This vehicle leaks through the sunroof and it goes all around the interior of the vehicle. Since it leaks inside I'm afraid it is going to reach the electrical components of the vehicle. It also leaks around where the battery is at an it can cause a shortage. Water also falls in through all the way to the carpet where the driver and passenger side, I don't know if the rear rows are affected. This makes the car have a ugly smell and sometimes I can't even breathe in my own car-- it smells extremely humid and horrible. The water that leaks in also leaves nasty marks around the interior roof of the car that really makes me feel depressed as soon as I open my door and see it. This problem really concerns me and I've also see multiple reviews of people with the same vehicle that have this problem. I can't drive my car in the rain or take it through the car wash without water leaking inside, and I hope one day it doesn't cause a fire in the electrical components.

While driving on the interstate the stabilitrak, traction control and reduced power lights came on. The car was running really rough and I had to cross traffic to pull over. I turned it off and sat for 5-10 minutes. I started it and it acted like nothing had happened. I drove it directly to a Chevy dealer and they said the only thing they could find was that it appeared that the throttle body had moisture in it and the moisture had frozen. They dried it out and its been fine, until last week. I was on my way to Chicago, again on the interstate, and the all the lights started coming on, then the engine light, but I did not lose power this time. I'm really afraid to drive my car and unfortunately I have several more trips to Chicago in the near future. I would take our other vehicle, but it is also a GM product and is having the same issues. I have read many forums where the same situation has been happening for as far back as 6 years and appears to be a major problem for a lot of GM owners. People are having sensors changed out, throttle body replaced and other work done on their vehicles and nothing is solving the problem. GM needs to find out what the problem is and fix it! its very dangerous to be driving along in wall to wall traffic and lights start coming on and there is the possibility of losing power in the middle of all that! unfortunately, since we have two GM vehicles with the same problem, there is no way to avoid driving one of them. Fyi - I also read that there are problems going on with leaks in the rack and pinion and sway bar issues. I had a leak in my rack and pinion and had to replace the sway bars last fall.

My 2008 GMC Acadia would not start and the key could not be removed from the ignition. The vehicle was towed to a GMC dealership. The mechanic diagnosed that the sunroof was leaking into the headliner and going straight to the fuse block. I had to replace the fuse block, battery as well as seal the leak around the sunroof and cowl. GMC refused to pay anything towards this repair and will not issue a recall. I spent $1,200 just to fix this due to GMC's poor craftsmanship. Mileage of car is 104,00.
