Fuel pump module leaks gasoline
During the course of this ea investigation, odi observed that the majority of the complaints (88%) and warranty claims (94%) were reported for vehicles that are registered for use in the salt belt region of the us.this area includes 20 states in the northeast, mid atlantic and the midwest regions and the district of columbia.consumers in the salt belt region reported to odi that they could smell fuel vapors in their vehicles while driving.upon further examination of their vehicles, they discovered that fuel vapors were coming out of the top of the fuel tank. This condition is caused by corrosion of the return and sender lines of the fuel pump module.water and road salt collect on top of the fuel pump leading to small pinholes appearing on the fuel lines.fuel may leak and collect on top of the module and/or spill onto the ground.the data evaluated under this investigation reflect a relatively low frequency of occurrence that largely arises in salt belt states.gm has extended the warranty on the subject component to ten years or 120,000 miles.further use of agency resources does not appear to be warranted at this time; accordingly, this investigation is closed.the closing of this investigation does not constitute a finding by the federal safety agency that no safety-related defect exists.the agency reserves the right to take further action if warranted by the circumstances.for additional information select document search.
EA07009
Fuel tank leak
In june 2007, gm will expand its special policy to address fuel tank inlet check valve (icv) fractures on certain model year (my) trailblazer ext and gmc envoy xl vehicles.the expanded policy covers my 2002-2004 trailblazer ext, gmc envoy xl, and gmc envoy xuv vehicles and will extend for a period of 10 years or 150,000 miles (whichever comes first).gm will provide free repair of the fuel tank. It is sending letters to owners beginning in june of 2007.this action supersedes gm's previous 7 year/70,000 mile special policy for my 2002 trailblazer ext and envoy xl vehicles.the condition is most often reported as illumination of the service engine soon (ses) light.the vehicle's diagnostic system detects the presence of a fuel system pressure leak and illuminates the ses light.other owners report smelling gasoline fumes. The action taken by the manufacturer is sufficient to resolve the issues raised by this investigation.the closing of this investigation does not constitute a finding by the federal safety agency that no safety-related defect exists.the agency reserves the right to take further action if warranted by the circumstances.
PE07014
Fuel pump module leaks gasoline
Odi has received reports that the fuel pump module leaks fuel and or vapor underneath the vehicle.gm states, the failure mechanism is corrosion of the fuel pump module flange which may lead to a fuel leak.corrosion of the fuel pump module flange is the result of the vehicle operating in a corrosive environment.odi has upgraded this pe to engineering analysis (ea07-009) to further assess this issue.
PE07013
Fuel spillage during refueling
This investigation was opened on the model year (my) 2003 chevrolet trailblazer.based on gm's information request (ir) response, odi added to its analysis the my 2003 gmc envoy and oldsmobile bravada vehicles.these vehicles share the same vehicle platform (gm 360/370) and fuel fill components.incident summary numbers reported above include these vehicles.epa regulates the fuel dispensing rates at filling stations and gm states that the reports of spitback for the subject vehicles are principally caused by fuel dispensing pumps exceeding the rate specified by epa.odi finds that the rate of complaints, field reports and warranty is low compared to other vehicles that have been recalled for a spitback issue.a safety-related defect trend has not been identified at this time and further use of the agency resources does not appear to be warranted.the closing of this investigation does not constitute a finding by the federal safety agency that no safety-related defect exists.the agency reserves the right to take further action if warranted by the circumstances.see attached report for additional information.

Has a bad gas smell leaking gas somewhere
The check engine light went on and there was a strong gas odor. Gas had also previously spilled out when fuelung.
The federal safety agency action number : pe07014 occurred on my vehicle around november 2014. The problem presented as p0442 cel and odor of gas after parking in garage. Gm has indicated because the special consideration allowance has expired, despite the low mileage they will do nothing. This vehicle was purchased new in august 2003. I do not understand why gm was not compelled to issue a safety recall due to the risk of gas leaking. I would appreciate assistance to get gm to minimally provide defective parts replacement, due to the know manufacturing defect in the gas tank.
Plastic weld connecting fuel fill pipe to fuel tank has cracked.contacted gm about this issue & was informed that this vehicle had just missed the campaign to fix this problem by one month. Why is this campaign (07099) a limited tsb & not a safety recall? Vehicle would not pass state emissions inspection. Technician repaired leak with epoxy that sealed long enough to prevent vapor leakage to pass emission test.now that has failed and once again vehicle will not pass emissions. More importantly the fuel vapors emitting from vehicle make it unsafe and impossible to park in an enclosed area.this is not due to a worn part or corrosion,this is due to a faulty design that eventually will cause an explosion.worse yet gm offers no discount on this very expensive tank assembly to correct this problem.I can not think of a more dangerous condition that has been so ignored.perhaps when the fires start there will be another congressional hearing about gm's ability to respond to such a serious and possibly loss of life hazard that they refuse to assist owners in correcting.
Ses light came on. Dealership had no apps brought to mechanic. Code was for fuel emission leak. Replace gas cap. Week later code ses came on again. Brought back to the mechanic, said fuel tank is cracked. Called chevy and was told there was a recall but not my VIN.....
There is a strong odor of gasoline vapors coming from the rear of the vehicle, a crack can be seen in the neck of the fuel tank. When filling the vehicle, fuel spills out of the tank from the crack. The fuel gauge cluster in the dash doesn't work. The blower on the A/C unit doesn't work on the highest (5) level. Also, the fan clutch went out causing the car to overheat severely. The fan does not engage, causing the water pump shaft to become damaged. Also, the rear driver side window quit functioning, despite buying an expensive new regulator and replacing it. Having researched the issues, I find that I am among hundreds, possibly thousands of unsatisfied people with the same problems.
Where the gas filler neck connects to the gad tank this area develops a crack allowing gas to leak from the vehicle and during filling up to a couple quarts of gas can run onto cement by the pump, also strong gas smell in the garage.. This also triggers the check motor light. According to internet postings other trail blazer owners are experiencing the same problem.
This is my second complaint due to a second problem with the fuel system. Vehicle was taken to dealership for gas leak, which turned out to be caused by 2 different, well-known fuel system problems. Gm offered no solution to either problem because I'm 3 months outside of the extended warranty. My total bill for both leaks was $1,500. Both leaks are known safety problems, as referenced in bulletins 07099 and 07076. I was told the vehicle should not be driven because of the leaks. Gas tank replacement is not what I consider normal a maintenance item. It is a known problem and these tanks need to be recalled.
Fuel leak on top of fuel tank. This is a known safety issue, and an extended service/warranty was added to fix this problem. The dealership said the vehicle should not be driven as-is. I did not receive notice of this warranty. Gm refuses to offer any more than a 10% discount, even though 3 months prior this same defect would have been fixed at no cost under the special warranty coverage. I was willing to split the cost 50/50, but no other options were deemed acceptable by gm. My vehicle is under the 120,000 mile cutoff as specified in the extended service, but 3 months out of date. Being this is a known problem and severe fire hazard, I feel gm should offer a better solution and at the minimum a reduced cost repair.
