Trailblazer 4WD 6-cyl

  • 180,000 miles


I have a 2003 Chevy Trailblazer and it started to have the smell of gas and a dip from the fuel tank. I was wondering if this was a fix that would be covered by General Motors. I have only owned this vehicle a year and live on a very limited income. I love this vehicle and do not want to have to part with it but I need a vehicle to go to doctors and hospitals for medical issues. Please help in getting this fixed.

The contact owns a 2003 Chevrolet Trailblazer. While driving at 40 mph, the transmission shifted between drive and overdrive. The contact also stated there was a fuel odor when driving. The vehicle was taken to an independent mechanic who diagnosed that the transmission shift kit and the fuel pump needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 110,000.

Gas has been spilling off the gas tank metal flange where the intake hose attaches too. Chevrolet dealer does not recognize this as a recall. Apparently a fatality needs to be directly link to this problem before this issue is address.

Service engine light illuminated due to leak in evac system according to diagnostic test. Dealership confirmed leak to be at weld where fill spout tube is attached to fuel tank. Strong gasoline fumes were present coming from the vehicle. I was informed that the fuel tank would have to be replaced at cost of $1300. Internet research revealed that GM had a tsb addressing this problem (campaign #05012), but it only applied to ext models. Since this is, in reality, a fire safety issue, I believe GM should also include all models with the same problem regardless of age or mileage.

Put vehicle in park and stayed in drive. Shut vehicle off and put on park however still in drive and now will not start. Since I work on vehicles I looked at transmission linkage and found cable came off transmission linkage. Plastic clip broken. Looked on line and found transmission shifter cable repair clip for $14.99. Since it was special order I went to dealer and was told there is no repair kit and that they have plenty of shifter cables in stock $75 went ahead and ordered aftermarket part special order 2 days and today 3 days later was told out of stock and none available til December. Coincidence or is this a common problem? I'm afraid someone will not know or realize vehicle still in drive when shifter moves to park and not moving shifter linkage at transmission.

About a week ago, there was a strong odor of gas inside the car. It appears also that I have been losing fuel as my tank went down much quicker than normal. I did look at the gas tank today and I see what appears to be a wet spot where fuel has leaked but do not see a hole. I have 2 young children and feel this is a hazard and defect of the vehicle. I do see that there was a bulletin on the ext model of the Trailblazer and feel this is the same issue.

Trailblazer 6-cyl

  • 95,000 miles
Like so many others, my 2003 Trailblazer began to reek of gasoline, permeating our garage & house with the smell. The dealership offered to replace the fuel pipes between the tank & the fill cap; however, they said I have to pay for the fuel filter myself. Note that prior to warranty work, there was no leaking, puddling of fuel, or any indication that it was leaking. There were just fumes. It has only 95K miles on it, so it's within the 120K/10 yr warranty for this problem. Unfortunately, when warranty work began, they "discovered" a leak when they removed the belt that holds the tank to the body of the vehicle. They are claiming that I "must have" gotten a rock or some debris underneath the belt to have caused the leak. Funny, it didn't leak until they touched it. Now the area rep is demanding "customer participation" in replacement of the fuel tank (which they admit is a safety hazard). Oh, & when they showed me the leak, I specifically asked if it was covered under the warranty and the service rep said "of course, you don't need to worry". but as soon as the GM area rep bailed on paying the escalated warranty work, the dealership recanted their promise to me. When I protested, the service manager suggested GM might not pay anything if I proceed with a warranty claim, costing me $1100+ for the fuel tank and $100+ for the fuel filter. I know the area rep has a fund to pay for it, but chooses not to. All service work including oil changes have been performed at the dealership on time, from day 1. the warranty service offered to me is less than others with the same problem have received (GM paid full repairs for others, incl. Fuel filter & fuel tank). I can prove that the vehicle was not leaking gasoline prior to the time warranty work began. History shows leaking gas tanks have a nasty tendency to blow up. Is that what it will take to make this right?

I noticed that there was a gas odor coming from the bottom of my SUV, and when I checked I found that there was a gas leak in the gas line that goes from the gas filter to the engine, and I also found out that two of those lines were stuck to each other. The one that had the leak was touching the chassis, so that when it vibrated it collided constantly with it. That's what caused the leak.

I have been smelling gasoline in and around my vehicle for about a year. One mechanic told us to replace the gas cap, which we did in November 2012. It didn't help. Now we are being told that the gas tank needs to be replaced which will cost hundreds of dollars. I am very concerned for the safety of my grandchildren that I pick up from school..

The vehicle had a very strong smell of gasoline inside the SUV and also outside and when I stopped on road fuel was pouring out of it and I got so frightened that it would catch fire. My fuel tank guage went from a full tank to less than a half tank of gas in a matter of minutes and the SUV was sluggish and felt weird. I took the SUV immediately to my car repair place and they dismantled the gas tank and found the fuel module to have a hole in it and is corroded. I looked online and there is a NHTSA action number of PE07013 on it and I found hundreds of complaints about this online and I am very upset as this repair is going to cost me close to a thousand dollars and I am a disabled american veteran and this amount of money is very hard for me to come up with. Also the SUV was very unsafe and if I continued to drive it I am sure it would have went up in flames. My SUV is at levines auto repair garage in new windsor NY 12553 and their number is 845-219-5508. I want to know what my rights are as to this matter. Thank you.
