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.

The gas gauge in my 2005 Ascender stopped working. It is always showing that the car is empty. I have noticed on the web that several other consumers have had this happen. There should be a recall.

  • 90,000 miles
The contact owns a 2005 Isuzu Ascender. The contact stated that the fuel gauge, speedometer and oil gauge were all providing erratic readings. After refueling the fuel tank, the fuel gauge would provide an erroneous reading of zero. The oil gauge pressure would move back and forth when the accelerator pedal was depressed. The vehicle was taken to a local mechanic for diagnosis and they stated that the fuel pump, sensor and the lever needed to be replaced. The manufacturer was notified and advised the contact to call General Motors because the parts were manufactured by General Motors. The contact notified General Motors but was referred back to the manufacturer of the vehicle. The vehicle was not repaired. The failure mileage was 90,000.
