GMC Envoy Xuv fuel leak problems

Filed Oct 27, 2016 · Fuel system · OH

Vehicle has had strong odor or raw fuel coming from driving side wheel well. Had mechanic check this out and I was told this has a fuel leak near the fuel filter / filler neck and possible gas tank issue which is close to the exhaust pipe. This is a known issue from gm owners but recall has not been advised. Informed gm of issue on 10/26 but they will not fix. This will cost upwards of $1100-$1600 to fix.

After refueling the vehicle, a strong odor of gasoline was present and the "service vehicle soon" light was lit. Using the on-star vehicle diagnostic service, the diagnostic code indicated a fuel system leak or loose gas cap. However, upon inspecting the vehicle it was found that the fuel tank inlet check valve, which is part of the fuel tank, was fractured and leaking fuel. In checking with gmc, there was an existing the federal safety agency action number: pe07014 concerning this defect for my make/model/year vehicle. A gmc special coverage policy extension (07099a) was also in effect since 2007 for 10 years or 150,000 miles to effectively repair this known fuel tank defect. This repair involves a complete replacement of the fuel tank. However, gmc refused to replace the fuel tank and cover the cost of repair because my VIN number was not in the listed range. In trying to repair the vehicle it was found that these fuel tanks are on backorder from gm as I suspect many gmc envoy owners are now becoming aware of this serious defect and were not informed at the initial recall because like my vehicle, they were not on the VIN number coverage list. Obviously the gm VIN number range for this defect is incorrect and should be expanded to cover all known 2002-2004 envoy, envoy xl and envoy xuv model vehicles. The cost of repair was over $1400. Gmc is the only source for this fuel tank as there are no other oem vendors. This is a dangerous defect of which I believe many gmc envoy owners are not aware of and can lead to explosion and serious injury if left undetected. Gmc needs to re-evaluate the VIN number ranges and notify all make/model/year owners immediately to check for fuel tank leakage and if necessary, cover the cost of replacement and repair. I have saved the fuel tank and repair receipts and can supply pictures of the defect if required/requested.

A year after the purchase of my new 2004 gmc envoy xuv my service engine light came on and an authorized service tech said I needed a new gas cap because of a small vapor leak. I bought the new cap and a few months later the engine light came on and again I bought another cap. From then I had been told by different mechanics that the vapor leak is coming from the nozzle the cap attaches to but today for the first time I was told I would fail my smog check because the vapor leak according to their diagnostics was not coming from the nozzle, but somewhere else near the tank. After research on recalls and complaints, I found out that my problem was similar to other complaints, that being the gm service bulletin 05-06-04-014a: info - diagnostic aids for trouble codes p0440, p0455 & / or p0442 fuel was leaking from the crack, and that the 2002 - 2004 envoy may have issues with a crack in the gas tank filler neck as well. I checked out the assembly system and yep my filler tank connection from hose to tank is loose and showing evidence of gas leaking down the tank. It wasn't a small vapor leak, it is a mushroom cloud event just waiting to happen to my backside! The interesting part of this disaster is that they did this as far back as I could search, so far as early as 2001. Gm had advised their mechanics that the problem was resolved and redesign of the system was in place with welded units attaching the components, rather than rubber booting to plastic tanks. I have the internal memo of their declarations for three years so far. Today, I'm in possession of a loaded bomb and see that tsb's are issued for years through 2009. Plus theres a discrepancy with service warranties of 10 years or 120,000 miles vs 150,000, I have those internal documents from gm to the dealers as well. I cant afford this. Other envoy owners I've talked to are saying the same things exactly.

Smell of gas inside of vehicle, check engine light on and notice of gas on garage floor. Took vehicle to a mechanic and found out that the gas tank was leaking around the neck of the tank where the refill hose connects. Found out that chevrolet and gmc had a special coverage adjustment # 07099a on this problem. I took my vehicle to the dealer and I was told that my vehicle is not covered on this sca because of the VIN number. I called gmc customer service on recalls and I was told the same thing. The dealer agreed to pay 2/3's of the bill and I will have to pay 1/3 of it. On the sca sheet it list the following for my vehicle. The last 8 digits of the VIN starting with 46100001 to 46116824. My vehicle is leaking so badly that I can smell gas inside of the vehicle all the time. It is very dangerous to drive. Also I park my vehicle in my garage all the time and this is dangerous. I think that all of the 2002 to 2004 chevrolet trail blazers and gmc envoys will have this problem with the leaking gas tanks. The problem is with the design of the tank. I was told by the service tech at the dealer that they use to have a lot of problems with the gas tanks. He said that since they have changed the tanks out on the covered vehicles that they have had none of the vehicles back in with leaking gas tanks. This is a big safety issue that needs to be corrected. Some people would not notice this problem and if they have an accident this could cause more injuries and possible deaths. This could also cause an explosion around sparks or static in someone's garage.
