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.

2008 Hummer H3 Owner Comments

problem #1

I was cut off by another driver in rush hour traffic and the horn failed to operate when pressed. After this incident, I discovered that the horn does not work after the vehicle is driven every few miles! the vehicle was in the shop for hours of diagnosis, and finally it was discovered by the technician that the vehicle has a bad "sir coil". the "sir coil" is on special order.
