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.

2007 Chevrolet Tahoe Owner Comments

problem #10

  • 52,000 miles


The top of the poly fuel tank has a recess for the electric fuel pump assembly which is gasket mounted within the tank. The two inch fuel line connectors atop the pump are metal. Due to the design of the poly fuel tank, water can collect within the recess and cause the metal lines to rust-out at the connection bends for the poly fuel lines to engine. The smell of gas starts out as being subtle, however become stronger as the rust pin holes get larger. The gasoline leakage occurs while the vehicle is in operation. This is can be a major safety hazzard if someone throws a smoking butt on the highway. There should be a recall to repair this design

This vehicle is only 8 years old and fuel lines, fuel pump are rusted to the point of failing to support the pressures within the system. Obviously, the type of steel, thickness of fuel line steel material is not made in such manner as to give a reasonable service life before failing. This is a clear failure of an important system within this vehicle that everyone relies on performing to a level of reasonable trust. This failure is only noticeable when you get a gas leak underneath the vehicle, too late and already putting owners at risk of fires or vehicle dying on highway traffic. This leak usually happens very close to the gas tank which is made of plastic, so you only need a source of ignition to cause great damage and / or loss of life. I noticed this fuel leak on the road, when I smelled gas inside the car so I stopped at a gas station to get gas and checked underneath the vehicle and noticed a gas leak coming from what it looked like on top of the gas tank. On further examination, found that the gas leak was coming from the fuel pump supply line connections which were rusted to the point of leaking like a fountain. Installed a new pump and connections only to find other steel lines also rusted and also leaking. Please, this needs to be looked into before some people unaware of these defects pay dearly for some big car maker like GM using inferior materials so they could raise their profit line, regardless of people safety.

While driving or idling, vehicle displays error messages stating "reduced engine power", "stabilitrak system disabled" and "service traction control." The engine power reduces and the vehicle hesitates upon acceleration. It is difficult to get the vehicle to accelerate, especially in lower gears. Sometimes the vehicle completely loses power in the middle of driving and all control of the vehicle is lost. This has occurred both on city streets and major highways. Purchased the vehicle used about 5 months ago and it began doing this at after about two weeks of ownership. Took it to a Chevrolet dealership and they said the throttle body was sticking and needed to be replaced. The problem seems to be getting worse over the last few weeks. The vehicle is now stalling on a regular basis (about 1-3 times every time it is driven). The problem is worse when it rains a lot outside. I am afraid to drive the vehicle with my children inside because I have lost power on in the middle of a major interstate twice.

Heavy gasoline fumes after vehicle driven a short distance. Fumes apparent at stops, sometimes while driving and parked. No trace of fumes or incipient leakage underhood, however there is weepage on the upper-inboard area of the tank itself. A very definite safety hazard!!!!!!!!!!!!!!!!!!!!!!

The complete fuel system rotted out from under the vehicle almost causing a fire. The fuel tank, fuel pump module, lock ring, fuel lines all had to be replaced and had to do a fuel spill clean up. Luckily, I caught the fuel spill before the Cadillac converter warmed up. My mechanic advised me to file a complaint with you because this should have never happened and feels GM should issue a recall due to a safety reasons.

This is the second incident. Was driving at 45 mph and made a turn. The Tahoe loss power and stalled. The computer read reduced engine power and stability trak off. This is bothersome being that this can happen anywhere at anytime. Afraid of possible accident or worse.
