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.

  • 18,500 miles


The contact owns a 2012 GMC Sierra 2500. When using the snow plow, the headlights dimmed and the heat decreased as if it were turned off. The contact mentioned that the volts decreased when using the plow, which may have caused the failure. The vehicle was taken to the dealer, but the cause of the failure could not be diagnosed. The manufacturer was made aware of the failure and sent an investigator to diagnose the vehicle. The vehicle was not repaired. The VIN was not available. The failure mileage was 18,500.
