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.

I have a fuel leak at the point where the fuel filler hose enters the fuel tank. I have researched this on the internet to find this is a very common problem with this vehicle. I feel that this is problem has the potential to cause fires and explosions.

I took my vehicle in for service because it failed emission testing and the repair shop told me that they have seen several vehicles like mine with a similar problem. I found that your NHTSA action number PE07014 is the problem that the repair shop found. I understand that the investigation into this is still open. The repair shop told me to contact the GMC dealer because they felt that the dealer should stand behind the problem and it is a safety issue. Will this become a recall issue and will the dealer need to replace the fuel tank at their expense?

I have a 2003 GMC Envoy XL. My check engine light came on. I had a mechanic hook his computer up to the vehicle. The code it gave was a bad gas cap. He replaced the gas cap and reset the computer. Two weeks later the check engine light came back on. I also smelled gas after filling the gas tank and noticed gas on my garage floor. I am having the gas tank dropped and checked this weekend. I wonder how many others are having the same problem?

When filling my gas tank, I have had a few issues with the pump shutting off too quickly as if the tank is full. However, I have also had the opposite at one particular gas station. Each time I got to this particular station, the gas pump clicks off, but gas continues to flow and spills into the tank and all over the vehicle. This only happens with my GMC Envoy and not any other family or friends' vehicles at the same gas station. It happens each and every time with the Envoy so we have had to stop using that station for the Envoy fill-ups. After seeing the many complaints about the cracked gas hose and issues with leaks, I wanted to make sure that someone knows there are a lot of problems with the gas tanks on the Envoy. I am very concerned that the design of the gas tank and assembly is a faulty design and will result in injuries.

The contact stated the gas tank on 2003 GMC Envoy had a leak in it where the spout went into the tank. He noticed this when the service engine light came on. He took vehicle to the dealer, and the dealer replaced the gas tank. The contact felt GMC should pay the expenses.

I have a 2003 GMC Envoy XL. My check engine light came on about 2-weeks ago. I took it into the dealer only to find out that my fuel tank had a leak. The dealer stated it was cracked at the filler neck at the tank. The tank had been leaking fuel and had to be replaced. In researching this on NHTSA, it appears that this has been happening to other consumers.
