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.

2003 Hummer H2 speedometer is not accurate or consistent. Currently the gauge is stuck above the max speed on the gauge. Earlier today the speedo went down to 35 mph while the vehicle was at a stop then clicked or surgered its way past 120mph while driving approx. 70mph. This is maddening and unsafe.
