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.

radio stopped functioning on August 26th. There was no volume, I could not change the stations by steering wheel or touch. The bluetooth would not work. The dash lights would not turn off and remained on the entire evening. I called GMC support and they said to unplug the battery, but I did not do so as I didn't want to mess anything up. I took the car in to the dealership the following day. I was told they see this issue often and by unplugging and resetting the battery, it will fix the issue. Problem resolved. radio stopped functioning again on September 2nd. Same issues as above. Took the car in and was told this time that it has something to do with onstar and they are working on a fix. Until they have a permanent solution, I was told if the issue happens again to press the white button on my rearview mirror. Problem resolved. radio stopped functioning again on September 3rd. Pressed the white button on the rearview mirror for over 20 minutes before the radio starting functioning properly again. Problem resolved. I called GMC to file a complaint on September 12 because the dealership general manager had not responded to me. GMC called the dealership and confirmed the issue was indeed related to the onstar component and that there is no fix. GMC said that it was probably not safe to drive the vehicle if the dash lights staying on are draining the battery. They went as far as saying they could get me a loaner car until my issue is fixed, but there is no eta. With GMC saying it's not safe to drive with that issue, I'm now not sure what to do with it.
