I was dropping the family off at a birthday party before going into work. The family kept complaining about the strong gas fumes. The smell was extremely overpowering. When I arrived at work, I noticed that it looked like gas was leaking around the middle of the gas tank, on top. Then, the gauge started not registering when gas was being put in. It is also very hard to start up. The vehicle takes 2 cranks before it will actually start up. When I asked a mechanic what it could possibly be, he stated that the Trailblazers are known for having an exposed area on top of tank that gets corroded and that the fuel pump and fuel sending unit would have to be replaced. The estimate was for $700-800 dollars. I cannot continue driving until it is repaired, otherwise, someone will flick a cigarette out window and the Trailblazer will blow up.

I am the original owner of a 2003 Trailblazer. During the last couple of months, my husband and I have been smelling gas off and on. We were parked in a parking lot and as I got into the car, I told my husband I smelled a strong odor of gas. Our engine light went on. We took our vehicle to the repair shop and they found a crack between the gas tank and the filler pipe and cap. We took our vehicle to a Chevrolet dealer and they said there was not a recall notice on our VIN # and they were not responsible for the replacement of the tank. We had a new fuel tank replaced at our local repair shop. The cost of the fuel tank replacement was $1,215.50. One spark in the road and we would have lost our lives. We understand that there was a recall notice on 2002 Trailblazer, but not 2003. What is the difference" safety is safety no matter what year. Does GM want to save a few dollars compared to lost lives" we were shocked on our internet research through tsbs which showed a great number of individuals owning a Trailblazer with this very same problem. GM should stand by their "safety and quality first" which we found online and reimburse all Chevrolet owners with this dangerous problem. There should definitely be a safety recall notice on this problem. The consumer stated GM agreed to reimburse the full amount for the previous repair. Updated 02/06/13

I am the original owner of a 2003 Chevy Trailblazer. When I first purchased the vehicle in the month of October/2002, I didn't experience any problems until maybe the fourth year, going on its 5th; right before the warranty was about to expire. The first problem I encountered with the vehicle was the transmission. It didn't want to change gears properly. Because of the 5 year warranty, the dealership was able to fix that problem, at that time. Today, I continue to experience transmission problems: With a loud noise, a struggle in horse power and a vibration when I am at a complete stop. I have spent so much money on other electrical parts as well. I have purchased over ten light bulbs for rear brake lights that continue to malfunction. I recently replaced a relay because the head lights would constantly go out after the vehicle was turned on. I replaced the fan clutch and water pump because they both went out. I also replaced a battery and two starters. For the past few months, my vehicle smells like fuel everytime I turn it on. I am asking that your department look into all of these claims. It appears that almost everyone that owes a 2003 Trailblazer has been experiencing the same issues, but yet; no one is doing enough to protect all those consumers who have been grateful to this country in purchasing american made vehicles. A sincere thanks.

My 2003 Trailblazer developed a fuel leak at the inlet check valve. Specifically I was informed by the dealership that the inlet valve has developed a crack in the weld and is leaking gas when the tank is full or while I am filling up the tank. I believe this is a dangerous situation and in doing some research appears to be a common problem with both the ext and regular models of Trailblazer. However only the ext models are under special coverage for replacement at this time.

Speedometer stopped working. After vehicle was turned off it started working again. Researched internet and I found the this is a known problem with this vehicle. After talking to someone about it and they have a 2003 Tahoe they have the same problem. If chevorlet is aware of this problem something should be done about it. We spend alot of money on vehicles and this should not happen. I don't feel this is a wear and tear issue.

Ses light came on - took to dealer and was advised of gas tank filler neck crack. Did smoke test to determine leak. Tried repair by sealing. That lasted 2 weeks and ses light came on again. Gave me estimate repairing with new tank approx $1500 or used tank $800. Did some research on the internet and found they was recall on extended Trailblazers (mine is not). Delved further and found service bulletin indicating GMC and Chevrolet has a special coverage adjustment #07099A. They ordered a new tank and installed at no expense to me.

I noticed a strong fuel odor coming from the vehicle. I researched the manufacturers tsb's and discovered there were two voluntary recall campaigns that had fuel odor symptoms. I inspected the components and found I had both issues, rusted feed and return lines on the fuel pump and a fractured filler neck on the tank. GM extended the warranty to 10 years and 150000 miles on one issue and 10 years and 120000 miles on the other. I currently have 158000 miles on my vehicle. My issue is with the voluntary recall notice I received. They clearly state that if there is no fuel odor present then do nothing at this time. If I had gone in for inspection at the time the notices were sent out, I would have been under the mileage cap and it would have been fixed under warranty. This is a major safety hazard and should have been a full blown safety recall. A voluntary recall is just a way to skirt the issue and save a buck. How many people are there like me who will not find a problem until it is too late. And it is too late by the time you can smell a fuel odor, that means there is raw fuel escaping from your tank. Now I have had to fix this problem at my substantial expense.

I am filing a complaint.and will continue to file complaints until all of the consumers issues have been addressed. I understand that GM is not willing to hold theirselfs liable for these issues, but people spend pretty pennies out of pocket to purchase vehicles from these manufacturers to spend more money to pay for repairs after just a short while of owning these. I have researched issues I am having with my vehicle, and I am having all the above listed issues, and do not wish to spend large amounts of money to pay for these cost considering I am still paying for this vehicle. I just spoke with a representive about these complaints, and have set up an appoinment to pay a dealership for diagnostics, but am hoping that I can get closure on these issues without paying big expenses. I hope everyone else will follow suit and keep inputting your complaints until they are resolved. My vehicle issues are the fan clutch needs replaced, my gas tank has been replaced already, just replaced my serpintine belt this morning, my exterior lights (brake/turn signal) have been replaced 3 times over two months, and engine light keeps coming on, something doesnt seem right underneath this vehicle either. I just feel like I am paying for a peice of junk on top of paying to keep the vehicle running. Oh yea this vehicle has had to have thousands of dollars of body work done as well thanks to mother nature. I just hope they will be responsible enough to take on this responsibilty of theirs, not ours.

After noticing strong gasoline odors in car and in the garage, the check engine light came on. According to diagnostic test run by dealership, this is the result of a leak in evac system. While researching, noticed other owners having same problem. Called GM, advised no recalls issued for this problem. GM offered no relief. Expressed my disappointment with rep since this problem could lead to very serious consequences thing the problem was caught since could have led to fire had there been an accident or an incinerator nearby. My cost to repair the manufacturers defect is $1600.

Service engine light illuminated due to leak in evac system according to diagnostic test. Smoke test showed leak to be at weld where fill spout tube is attached to fuel tank. Gasoline fumes were present were present from the vehicle. Was infonmed that tank would have to be replaced ala cost of $1200. Did some intemet research and found that GM had a tsb addressing this problem (campaign #05012), but it only applied to 2002 ext models. Since this is, in reality, a fire safety issue, I feel GM should also include other models with the same problem regardless of age or milage. Updated 01/20/11
