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.

The contact owns a 2008 GMC Acadia. The vehicle of the contact's sister was rear ended by a drunk driver at a traffic light. The contact discovered that the driver seat was fractured and the seat detached from its springs and hinges. The air bags failed to deploy. The contact sustained lower back and face injuries that required medical attention. A police report was filed. The vehicle was towed to a towing company and the insurance company had possession of the vehicle. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 83,000.

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.

1. accelerator pedal stuck to floor at 60mph and continued to pick up speed until driver threw car to neutral as brakes would not engage 2. air bag system has not been functional 3. 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!

Transmission wave plate issues....the car shifts into different gears and about caused an accident. Took it to a mechanic and it is a transmission wave plate that needs replaced. Going to cost us around $4000. Just spent 1000 dollars to fix the power seats that quit working also.

I purchased a new 2008 GMC Acadia in Sept. Of 2007 and I have had several problems with is sense buying. The biggest problem is my second row of seating it has a 60/40 split and the 60 portion pops up all the time even when an adult is sitting on it. I have taken to two different GMC dealerships 7 times and no one can find anything wrong. I even contacted GM's main office and they said they can not do anything until the service dept. Finds a problem. Their only suggestion was to take it to a third dealer and see if they can find what's wrong. I feel that is a very unfair to me because that just means I have to drive further to find a dealer and waste more time on something that should have been fixed a year and a half ago. I have 3 kids and they can not even sit on that seat because you never know when its going to catapult them up and into the back of the drivers seat. We can't even put our youngest carseat in the seat. This has just been very upsetting and I am tired of dealing with GM and the salesperson I bought the car from is the one who suggested I contact you. Again we bought this car brand new. The other things that are wrong is I still have water leaking in the top of the drivers window when it's sitting during a hard rain, , my fan motor for the A/C and heat goes up and down all by it's self and paint is peeling off the hood. These are things I guess I can deal with but the seat has got to get corrected. I hope you can help, thank you and look forward to hearing from someone.

2008 GMC Acadia has several problems with safety recalls and dealership response. Water entered through the passenger side roof. The tire pressure monitoring light illuminated. The driver seat made a noise while being adjusted and there was a noise coming from the steering column when it was cold. The radio and navigation screen went out and the drivers seat did not move.
