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.

Rain water leaks in over the driver'seat saturating the roof liner running down the windshield column on to the floor. Water shorted out the power window control. Drain lines on both sides of vehicle are constantly being checked for blockage but no blocked. Inside of windows get ice during winter and humidity buildup when temps are above freezing. I believe it happens more often when the car is stationary. It started about Oct 2013

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??

Acadia 6-cyl

  • miles
There is a potential fire hazard with the daylight running lights overheating before they burn out on both driver and passenger side. The bulb gets so hot that they melt the bulb socket causing an electrical fire hazard. The heat also has made the headlight housing brittle and cracked to where the socket wont stay in place inside the headlight housing thus causing the bulb to lay on the plastic causing a fire hazard. General Motors knows about this fire hazard because I have called it to there attention and because they have a customer satisfaction program #13135. They have also recalled some 2007 and 2009 to 2011 vehicles but not 2008 with the same problem.

Acadia 6-cyl

  • 63,550 miles
I purchased this vehicle from the GM dealer in anchorage Alaska on Jan. 27, 2014. At approximately 63550 miles, during a hared rain storm, water entered the vehicle from some point. It poured out of the interior heating fan cover, under the glove box on the passenger side of the vehicle. It covered and soaked the floor mats and insulation around the area. In order to determine the extent of the leak, I removed the glove box and the heating system fan cover. The fan cover was completely full of water. I removed about 3 cups once and only hours later it was full again.
