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.

The contact owns a 2003 GMC Envoy. The contact smelled gasoline, but did not pay it any attention initially. His son entered the vehicle later and also smelled the strong odor. The following day the contact filled up the tank with gasoline and the smell intensified. When he arrived home, he noticed a fuel leak by the rear driver side wheel. A mechanic stated that the leak originated from the top of the fuel tank where the fuel pump connects. The contact dropped the vehicle off at the dealer the next day and they stated that the leak originated from the gas tank, and it needed to be completely replaced. The vehicle is still at the dealer. The current and failure mileages were 59,000. Updated 04/16/08. The transmission was slipping and would not engage in 1st gear. The air condtion was blowing hot air. The ignition swithc shorted out.

There is a fueling problem with the vehicle. The problem is intermittent but happens regularly enough (30% to 40% of the time) to have the potential to be a safety hazard or cause serious physical hazard to the operator. The vehicle on occasion will not accept gas into the fuel tank and then will immediately cut off the fuel supply and then back up and splash fuel out onto the operator while attempting to fuel the vehicle. It may take numerous attempts before the tank will accept the fuel, all the while splashing fuel out of the filler on each attempt. On other occasions, the tank, as it approaches full, will just splash gas out of the fuel filler without warning or any indication without cutting off the gas pump fill hose as it normally would. This condition can be a serious physical and health hazard to the operator since gas gets on the skin and the cloths of the operator, causing a burning sensation and subjecting the operator to other safety concerns. The fuel spill can also be considered an environmental and fire hazard. A number of different gas pumps and gas stations have been tried with the same results during fueling. This would rule out a problem with one pump or filling station causing the problem. The problem has even occurred in different cities.

When filling up the gas tank, often times the pump will not stop and the pump will run about 3-5 seconds longer than it should, causing gas to spill. Dealer checked and found no problems (but saw on the website another user experienced the same thing).

My 2003 GMC Envoy has a defective fuel tank. According to the dealer the tank has a small crack in the vapor recovery line. Dealer and GMC claims that it is not a hazzard but there is a very strong gasoline oder when the vehicle is started or stoped and it continues for some time until the engine is warm. Dealer claims the tank is being redesigned GMC will not confirm or deny. What I know is the part has an expected but not definet 4 to 6 week delivery time.
