Selected complaints filed with NHTSA by 2007 Chevrolet Tahoe owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2007 Chevrolet Tahoe. The contact was unable to refuel the vehicle, due to the filler pipe not allowing the vehicle to accept the fuel. The contact stated it took her 30 - 45 minutes to refill the vehicle. The contact also stated occasionally while refueling, the fuel would start to leak. The contact stated that the check engine warning light was illuminated. The contact took the vehicle to an independent mechanic and was informed that the evap system needed to be replaced. The vehicle was not diagnosed or repaired. A dealer was not contacted. The manufacturer had not been informed of the failure. The failure mileage was approximately 235,000.
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. …
The dash cracked on passenger side 80 k.this vehicle is very well-maintained it looks like it rolled off the showroom floor. Takata airbag recall what a joke. So you recall the vehicle but you don't have the parts to fix it. The vehicle has a defect in the fuel system, I started noticing it when I would fill up with fuel. It has to build the pressure up before it'll start. Many mechanics told me this is a defect. Kat Friday night I ran an errand. Pulled in the driveway exited the vehicle hit the key fob to lock the vehicle. I go out the next morning and I can smell burnt wires. The window/power locks/mirrors module on drivers side door caught on fire. Luckily it shorted out the module, but it burnt up and melted one of the connectors. This just happened so I have not had time to figure the cause. Burns 2 quarts of oil between oil changes. …
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. …
The top of the fuel pump rusts out. The fuel tank has a design flaw that holds water around the fuel pump. The fuel pump and fuel lines on top of the tank rust out and causes gas and fumes to escape the tank. Fuel will spray onto exhaust and under the vehicle causing a fire hazard. Also excessive fuel vapors escape the tank. I have researched the problem online and there are numerous complaints to GM of the problem but GM has not addressed the problem. I am not looking for any monetary gain I simply want GM to address the problem before someone is killed. Some people reported the problem before 100,000 miles and nearly all problems occur before 150,000.
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
My 2007 Chevrolet Tahoe developed a fuel leak at the discharge of the fuel pump. The leak occurred on the top of the fuel tank directly below the left rear passenger seat. The leak sprayed fuel all over the gas tank and bottom of the truck body. This is a safety concern due to the possibility of the atomized fuel starting on fire. The driver or passengers could have been severely burned. The vehicle was in motion when the leak occurred. I noticed a very strong smell of fuel, I pulled over and gas was dripping off of the fuel tank. The fuel line depressurized after the engine was shut off and continued to spray gas for 10 to 15 seconds.
Tl contact owns a 2007 Chevrolet Tahoe. While parked in the garage, the vehicle suddenly caught fire. The fire department investigated and stated that the fire originated from underneath the hood. They also advised her to not move the vehicle until it has been inspected by the dealer. A police report was filed and two people sustained injuries. She believes the fuel pump caused the failure because the explosion was very large. The VIN, engine size, and number of cylinders were unknown. The current and failure mileages were 11,700.
Fuel leak came every time I fuel up, smell got inside the truck , I took it in for service was told seal between pump housing and tank seals and lines leaving tank made from plastic needed changing leaking ass well there is rust on the top of the housing of pump but no rust any where else on the truck estimated cost of repair 1500.00 tech at dealer said common problem but no recall issued yet since fuel leak issues are dangerous and they happen out of the blue
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.
