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.

There seems to be an overwhelming amount of error code PO442 in the 2003 GMC Envoy and Chevy trailblazers. This code is a faulty gas tank that over time develops a small leak. The only way to fix it is to replace the tank. This cost anywhere between $1000 - $1500 to replace. If there is a gas leak there can be a fire!!!

I own a 2003 GMC Envoy. I am the original owner. The service engine light came on so we visited the local dealership to find out what was wrong. Upon testing the vehicle there was a crack found at the stem of the fuel tank. It had been leaking fuel and loosing pressure causing the light to illuminate. The repair bill is around $1400 for a safety hazard that was no fault of mine. The service manager said that it was a bad design due to epa regulations on venting the cap and that he had seen many of these. I contacted GM and they were not willing to help. They offered a discount on a new or used car. There is no current recall but the more I look into this, there have been many issues of this happening. This problem could kill many people.

When I fill my Envoy with gas, it will not stop when it is full. The gas then spills over onto the side of the SUV and causes me to clean it immediately and smell like gas. I know that it is the SUV and not the pump because it doesn't happen with my other vehicle at the same pump.

: the contact stated while driving 10 mph the vehicle stalled and was maneuvered off the road. When the vehicle was being prepared to be towed the towman noticed gas leaking. The dealer confirmed the leak and determined the tank shifted causing the gas line to crack. The dealer replaced the entire gas tank which corrected the problem.
