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 Sierra 3500 Owner Comments

problem #1

Sierra 3500 8-cyl Diesel

  • 73,883 miles


I drove my wife to the pharmacy and after pulling out of the parking lot onto palmdale road in victorville the truck went into to limp mode. The transmission locked up into park at 25mph almost causing a rear collision behind us. The GMC Sierra 3500hd 2009 came to a screeching stop causing a bit of whiplash to my wife and daughter on board. The tcm transmission control module along with the allison transmission failed causing this close accident. The vehicle is inoperable at this time. This is a dangerous defect.
