The tahoe used as our volunteer fire department medical truck was spewing fuel from above the gas tank. We dropped the tank and found the lines on the top of the fuel tank rusted severely to the point of failure. It was first noticed on a medical run with the engine idling.

1. While driving on the interstate at approx. 55-65 mps, my 2004 chevy tahoe shut down almost causing an accident. This has happen to me several time until I found out the mileage, fuel and the hole system wasn't tell the correct reading. 2. Also the air stops blowing on the passing side when the as is on. When the AC is off it still blows heat only on the passenger side. 3. When your driving the vehicle and stops at a red light then get back on the gas to pull off it acts like it don't want to pull until I get off the gas then get back on it like the transmission is slipping. So I had the strainer, filter and gasket change on the transmission and it still does it. 4. When I get ready to park the truck does put-put sound like it wants to shut off then it picks back up.

Smelled gas coming from the rear passenger side of the car (on exterior) and was informed that the metal ring molded into the plastic tank where the sending unit mounts to the tank had rusted out and gas was accumulating in the "bowl" that the connection is in. Rusting is a result of water accumulating in the "bowl" where the unit mounts and not being able to drain out. Did some online research and found that a number of tahoe owners have had the same issue. Was also informed that chevrolet determined this was an issue and changed the design of the tank in future models to remove the metal ring that the sending unit mounted to. Cost to repair at chevrolet and independent garage $2,000 or more.

Vehicle registered "reduced engine power" while I was on the highway, I was able to get to the shoulder, online research showed numerous incidents involving the throttle body sensor and the wires crimping, there was something about the wiring harness being covered by gm but it does not appear on a recall list.

Top of the fuel pump and those related fuel lines failed leading to a significant fuel leak, and really expensive repair. This truck is ten years old, fuel system parts shouldn't be rusting out like this. No other vehicle I've ever owned, no matter how old, has had an issue like this. Life safety and fire risk!

Approx. 6 months ago I was driving when a vehicle entered the intersection in front of me. I stepped on the brakes and the pedal went to the floor. Luckily there was no crash but my vehicle just barely came to a stop. Towed the vehicle to a dealership and found all the brake lines were rusted out and needed to be replaced. On 3/28/14 I began noticing strong gas fumes coming from my vehicle. I again took it it in and found the fuel pump assembly, all the fuel hoses, and the straps and bolts that hold the fuel tank were rusted out. I read that the federal safety agency was doing a study of this issue. I understand my vehicle is 10 years old and I live in the northeast but I observed a lot of rust under my vehicle. I am a police officer and a crash reconstructionist and these rust issues could cause serious issues with vehicles resulting in crashes. I feel this issue needs to be investigated because it effects crucial systems like the brakes and fuel systems. Please feel free to contact me for further information.

I was driving on e-470 westbound near quebec when the car shutdown completely. No power. The car then would not start and had to be towed to the dealer to have a computer check. They told me it was the fuel pump, after a week, when I was having it towed to my mechanic for the repair, I decided to try to start it and it started right up. I drove it to my mechanic who checked the fuel pump and said it was fine. They could not find a reason why this happened. Same with another mechanic. Since then (I had owned the car for 5 months at that point) this has happened four more times, the latest on may 9th. Again it's been towed and again I am trying to find a permanent solution. I am now finding out the passlock anti-theft system malfunctions and cuts off fuel to the pump because the car thinks it is being stolen. I have also learned it has been a common problem in many gmc models over many years. Sometimes the passlock system can be reset (though that has never worked for me). The only way to permanently fix the problem is to disable the passlock anti-theft system. These systems should be removed from these cars. I would rather my car be stolen then shut down at 65 MPH or when my wife is driving home from downtown denver at 10:30 at night through not so great parts of town.

My wife and I bought the vehicle new. It was always kept in a garage and driven very little. As of today it only has 30,000 miles on it. To begin with, on or near march 2007 after exiting the vehicle I noticed a strong smell of gasoline. I looked under the car and I saw a fairly heavy dripping of gas from the top of the gas tank. I drove it to a mechanic that I have been using for many years. He told me that he had a hard time finding where the gas was coming from but with a mirror , he was able to see that it was coming from the fuel pump or what he called the fuel sending unit. He said it appearred to be coming from the pump in thr top of the tank and that it was badly rusted and needed to be replaced. I called the dealer from who we had bought the tahoe and asked if there were any recalls to this. They said no. I should also tell you that the mechanic told me that he had replaced many of this same tanks. He said it was built in such a way as to be shaped like a bowl and that the water just laid in it. It cost me 750.00 to get a new fuel sending unit put in. About 4 years later, the exact same thing happened. The entire top of the pump was rusted out and again gas leaked out . Enough gas leaked out to almost cover my entire garage floor. This really kind of scared me. Even just any kink of a small spark and not only me but my hole house with five other people not might of got hurt, with this much gas we would have been dead.. Again I checked for recalls of which there were none and ended having again a new fuel pump installed. The only difference being that he.
