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.

The contact owns a 2008 GMC Acadia. While the vehicle was parked, the airbag light illuminated stating the air bags needed to be serviced and would not detect anyone sitting in the passenger seat. The vehicle was taken to the dealer for diagnosis but was not diagnosed or repaired. The approximate failure mileage was 29,000.

The contact owns a 2008 GMC Acadia. While driving approximately 55 mph with a passenger in the front passenger seat she noticed that the air bag light was not illuminating, which indicated that the front passenger side air bag would not deploy in the event of a crash. The vehicle was taken to an authorized dealer where she was informed the passenger must be at least 70 pounds for the front passenger side air bag to function; therefore, it was not repaired. The failure continued to recur whenever smaller passengers would sit in the front passenger seat. The failure would also intermittently recur when average sized adults would sit in the front passenger seat. The vehicle was taken back to an authorized dealer where she was informed the vehicle was functioning properly and it was not repaired. The failure mileage was unknown and the current mileage was 60,000.

Adult passenger seated in the passenger front seat with an approximate weight of 120lbs and a height of 5'3" does not enable the airbag sensor to turn on. The system does not enable the airbags even though an adult is seated in this position. We have taken the vehicle to the dealer twice and they have not been able to repair the issue.

This is the second time, within two weeks, I have taken my GMC Acadia slt2 AWD 2008 to be serviced for a leaky sunroof. I am getting major water damage in the wiring system, and airbag holder. I have more miles on my rental van, then my brand new Acadia.
