Recently reported FUEL SYSTEM, GASOLINE problems on 2003 Chevrolet TrailBlazer

Within seconds of filling the fuel tank, fuel splashed back out of the fuel tank filler neck. *ak *scc *jb

When filling gas tank, when nozzle shuts off ,gas belches out of tank filler tube. spalashes gas on shoes and clothing. also gets gas on inside of car fender.you can then smell gas fumes when car is parked in garage.*ak

2003 chevrolet trailblazers 3-4 weeks ago my service engine soon light came on and i took it to the dealership who showed me a leak at the junction of the gas tank and the hose from where you fill up the tank. the service man tightened the clamp. the light came on again and i took the tb back and was told the connection was cracked and that the tank had to be replaced. i haven't been in an accident, haven't run over anything etc to cause this. i am having the tank replaced-- *nm

I struck what appeared to be a small piece of debris on the interstate. i found out an hour later that it punctured my fuel tank. unfortunately i did not find out about the leak until the parking garage i parked in for that 1 hour was closed by the fire department due to my leak. how can a sport utility vehicle have a plastic gas tank and no skid plate for protection? the gas tank is on "back order" from gm. is there a problem with this set up?*ak

While fueling verhicle, fuel always spills over just before or after auto-shutoff of gas pump. this happens even though i'm careful that it's coming close to a full tank and prepare for the spillage. today it happened at a pump where the fuel pump nozzle was of a non-accordian type boot. i've spoken with others who have the same problem and dealers are telling them to be more careful when re-fueling. what will it take gm to admit there's a design flaw in the fuel delivery system? this is only one of many issues with the trailblazer. you'd think for what they cost that they'd be built better.*ak

Gas spilled over from spout and underside. with the amount of gas spilled, overflow got all over vehicle and person at the gas pump. had to wash off shoes, clothing and lower leg area due to excessive gas spillage! extremely dangerous! *nlm

Gas filler tube overflows on to the ground almost every time the vehicle is filled up with gas. has done this since purchase. tested different gas stations pumps thinking that was the cause but it does this at all of them about a second or so after the pump clicks off. also the filler tube boot has a built in hole for the gas to drain on to the ground....which ( on the better side i guess) does keep it from getting on the side of the vehicle on occasion.

When filling the fuel tank on 2003 trailblazers with fuel pump equipped with "accordion" neck sleeves, fuel has the possibility of back flushing out the top of the tank neck. i experience this on multiple gas stations here in california with multiple 2003 trailblazers. about 1 cup of gasoline flows over the intake and on to the car and ground causing a serious hazard. the back flow spill does not seem to occur on every type of fuel pump, but only on those equipped with certain sleeves over the nozzle. other trailblazer owners i have talked to in my area also experience this problem. the dealer has not only not been able to duplicate the problem at their local station but has no remedy for the multiple times we have brought the vehicle in for service. *nlm

New vehicle delivered with dangerous factory defect: gas filler tube has crack- allows fuel to spill out during fueling of vehicle. dealership does not have part on hand for repair. *nlm

When 2003 chevrolet trailblazer is filled with gas, gas comes back out of trailbzer to form up to a 2ft. puddle of gas on the ground! gas up to 2ft. wide down the paint! my 2 1/2 year old son strapped in car seat and others have been inside when this has happened,mainly at renton wa. safeway gas pumps, but other pumps as well! i told good chevrolet in renton wa. as far back as april 2003 of this problem and at first they claimed their was no problems whatsoever with trailblazers, but some chevy tahoe suv's had the problem! maybe i didn't know how to fill a tank, try a different gas station, don't remove nozzle for a few seconds...i tried everything they said and kept calling and telling them of the problem!!! i asked for one of them to come with me and witness it and they declined! by may and june im still telling good chevrolet of the continuing problem! they ask to look at the trailblazers tank and fill tube.. maybe its kinked, fill tube or ball check problem...they said it looks great nothing found,and they filled it with gas at their pump and no gas came out at all! i had told them to fill it at the renton safeway!!!!!,but they didn't!!!! i wonder why?...bob manning the service manager at good chevrolet had been advised of all this in many phone calls to him! now in july they want to replace the filler neck and tank. when they fill it again they still do not go to renton safeway like i told them again..i fill it and gas comes out!!! i call again and ask again for a witness from good chevrolet, finally they send a tech. with me. we drive to renton safeway i put the nozzle in tank, put on the "clicker" stand back, the tank fills and as they clicker shuts off when the tanks is full, gas comes out and forms a puddle on the ground!!!! i've called the bbb, attorney general and now you...the trailblazer also has large pops of static discharge constantly! i was stone walled with my concerns! *jb
