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.

Needles on fuel gauge goes all the way around and points vertical. Needle crashes into the thermometer needle that also points vertical. Does not correctly register fuel or temperature. I am depending on my odometer to guess at my fuel levels. This seems to have started after my "loose gas cap" alarm came on. I had cap replaced 2 times, light will not go off. This, of course makes the service vehicle soon light stay on.

The first incident was around 40,000 miles. The gas gauge would not work, after filling it up the gauge would "stick" or the hand would drop down to the thermostat needle. Very erratic. Carried it to the dealer and naturally, everything appeared to be working. 52,000 miles and the gauge is dead - of course the warranty was out also. It was explained that I would have to replace the entire cluster of gauges and I could not afford that at the time. Car now has 79,000 miles, I have been using the odometer so I will know when I need gas. A few weeks ago, looked at the speedometer and it read my speed as 120 mph. I immediately pulled over and at a dead stop, the speedometer was setting on 60 mph. Now I am concerned about the entire cluster readings. The thermostat will jump up to the red, hot reading which is wrong. Now I am going to be out huge dollars that appears to be something GM should repair.

The contact owns a 2005 Buick Lesabre. The contact stated the fuel gauge would inaccurately show that the fuel tank was full at all times. After he would refuel, the fuel gauge would not move.
