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.

2009 GMC Yukon Owner Comments

problem #1

Oct 232011

I placed the vehicle in park on a level surface, I left the Yukon running and I got out and walked my great niece to a building about 30 feet from the vehicle.. I then turned to see the Yukon backing up on this flat surface, I ran to try and catch it but it hit a building and then came forward at me. I had to jump out of it's way and then chase it down. When I jumped in and hit the brake I then noticed it was in M1. I took it to a local GMC dealer who checked the transmission but reported finding nothing. I am now afraid of this car. How do you know when it will vibrate or jump from park to reverse again. This needs checking into. This Yukon went both backward & forward.
