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.

Hello, I am second owner of GMC Envoy sle 2003 car. Couple months ago the light check engine soon started appears and disappear after filling gas and several trips. June this year I went to dealer service from where I buy the car three years ago.they fixed some thing (housing and / or gasket, thermostat replace and for campaign 07076: Fuel sender module update T5714 fuel sender assy replacement and etc). After 600 miles the light appears again and stays steady. I called to my dealer, but now the dealer is out of business. I went to other service. The service advisor sad me that the reason for the light on is the car has gas tank leaking near fuel filler tube area may be from corrosion or crack and that's mean near $1500 for brand new tank and service and couple days for delivery the tank. Because I don¿T understood very well the explanations and didn't know how dangerous this leaking is I left very upset without repaired. I called to GMC to ask: Is it normal for 7-th year old car to change the gas tank. I think this is ridiculous. (after own the car, three year ago, I didn't hit it.) follow discussion with two departments and after all I understood: This is my problem and responsibility is mine. That is it. Thank you.

2003 GMC Envoy filler neck leaking. This is a known issue and there is a recall. When I took my truck to the dealership it had this issue but the recall is for the XL model. This is a major safety issue. How can they mess around with leaking gas? it is a 1200+ repair that should be covered.

We have a 2003 GMC Envoy slt. Everytime we put gas in the vehicle it doesn't shut off like it should. The gas will overflow and go all on the vehicle and all on the ground. We have owned the truck for approx. 1.5 months. This happens everytime we get gas. I have never had a vehicle do this everytime. It has been from different gas stations.

Gas fumes coming from 2003 GMC Envoy. Took to service department at authorized dealer. GM refuses to fix problem which is covered under service bulletin 07076/NHTSA item #10026522. GM customer service refuses to replace tank that is cracked due to corrosion caused by fuel tank modular reservoir. Service bulletin state all repairs will be made with no charge to the customer. Envoy has been in the repair shop for 5 days.

2003 Envoy slt -135,000 miles --ses light on, local mechanic said small evap code indicated inlet checkvalve fracture- they said go to GM dealer for help with this, info printout from local mechanic given to me- "all data motor" said recall spec. Coverage for ext. Size models of Envoy etc. Offered by GM for period of 10 yrs or 150,000 miles.(also 11/04 they did work warranty work on code 440 and replaced seals, tank unit, I think they caused this because I was having the ses light on&off years and just told loose gas cap- so I bought a new one but now this! dealer looked and said "no" after I was there for 5 hrs. Said I could buy a new gas tank @ $1200. I said I didn't have the money. Told I could call GM so I did. Thought I would get "goodwill" help for same problem as they paid for the extended models. I talked to two reps.rep said my VIN was listed in the coverage range of #'s but not my model. But she proceeded to take my info in order to get me some called me back 4 days later in a hurry to look at it again with another mechanic that apparently their district GM person said to do. The home office for the GM service person called them with my complaint. They still looked at it and saw the gas leak at the icv and then still just told me "no" that my model didn't qualify for help like the extended Envoy did. I told them it appeared to be the same engineering problem so why wouldn't my model be covered" my service rep just said I would have to buy a tank. I said "no". he said just keep the gas tank below half full. So that is what I have done for the past week. I don't want to trigger that ses light by filling up the tank near that hose inlet. This does not make sense that they will not cover this problem for my model- is there some big difference on extended length? maybe enough short Envoy and trailblazers haven't sought help for the same problem. Is the engineering design of gastank and icv different on the short and long model Envoy?"

Had gas pouring from 2003 GMC Envoy. The sending return part is bad, the GMC dealer said part is over $400 and has to be ordered from California, my warranty does not cover it and from what I have read on here, it has been quite a few Envoy with the same problem. My Envoy was originally a lease and came from pa which we were not told. We were told the warranty we purchased covered bumper to bumper but does not, the part will be 5 days coming and meantime, I have no car to drive until ?I get it back. I think since the gas leaks so much, and could have caused a fire or and an explosion something needs to be done. Thank you for any information you may be able to offer.

When driving my 2003 Envoy it smelled strongly of gas and upon parking, it was leaking gas all over the ground, I had it towed and the sending unit was bad, if it had sparked or there had been an aec, it could have caught fire and the cost is $ $1000 and I have to pay out of pocket. The first extended service corporation will not cover it, the warranty was falsely offered to me by the sales rep at waestcott Buick burlington nc and was costly and worthless. The Envoy was a lease out of pa, which also was not disclosed to us. This has been a huge cost and disappointment.

I could smell a gasoline odor around my 2003 Envoy (45,860 miles). Took vehicle to coulter of tempe (an authorized GM dealer) and was advised of a leak at fuel inlet to tank pipe area. Was told gas tank would need to be replaced. GM has had a similar problem with the 2003 Envoy XLS and issued a letter dated June 2007 covering the entire amount of replacing these fuel tanks for 10 years or 150,000 miles. This coverage should be extended to all 2003 Envoy and a possible recall issued as this leak at the fuel filler neck seam at the tank is not easily identified unless vehicle is hoisted on a lift. They did offer us a deal where we were charged a warranty deductible of $500, but I feel this repair should have been covered in its entirety.

Also every time I fill my gas tank, gas comes back up and spills out, it does not matter if I leave the nozzle in, take it out immediately, and I am never topping the tank off. When I had it back to the dealer they said they were unaware of any problems.
