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.

2007 GMC Acadia Owner Comments

problem #1

Acadia 6-cyl

  • Automatic transmission
  • 0 miles


I have had my transmission worked on already on my 2007 GMC Acadia the speed control in the transmission has been replaced but I still have a problem with the performance of the car. It is an all wheel drive with an automatic. It will not hold on a hill and searches for a gear or chances several times when it comes to any kind of incline even at 70 mph.I was getting 15 miles to the gallon before the new speed control now I get 13. I have spoken to my dealer several times and he says to wait and soon there should be a update in the software to address this problem I am willing to wait but want it on record that the transmission has problems. This is a new design and is very rough riding. My car has only 5000 miles on it and I have been there 4 times.
