Water has been seen several times dripping from underneath the truck in the center area. It appears to be from the emissions system. No wet weather at the time. It appears to be some sort of condensation. Also fan clutch failure, sway bar linkages failure, tie-rod failure, rack and pinion failure/leak, control arm failures 2 times, windshield wiper would not turn off failure, windshield wiper reservoir tank leak replaced, ac cold air failure. All needed to be replaced on a vehicle less than 5 years old with only 38,000 miles on it.

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!
