Vehicle has 160,000 miles on it and they will not pay for repairs that should actually be a recall since it is a safety issue that is affecting millions of vehicles

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 $1300.00. 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.

My 2003 chevy trailblazer check engine light comes on accompanied by the low engine power light. The vehicle goes into limp mode. This is a safety feature that allows the computer to protect the engine from any damage should something go wrong. The only problem is that there is nothing wrong. This happens multiple times a day (6-8). Changing sensors doesn't fix it. I believe it to be a problem with the 2003 chevy trailblazer computer. I have read many forums with hundreds of people that have this same problem. Please look into it before it causes an accident or makes an emergency situation a fatal one.

Was driving on the highway to lansing when my check engine light came on and I lost all power and guage function.I began to hear a loud howling noise, pulled off at the exit went to the repair shop in portland, mi where my wheel hub exploded in their hand on the passenger side. The fan clutch has completely stopped working witch caused the vehicle to overheat, and loose all power and my 4 wheel drive locked right up and stopped working. This was extremely dangerous at a rate of 70 MPH because the vehicle slowed all the way down to 25 and had no power. I have had so many issues with this vehicle that I am now checking for recalls to have the vehicle serviced completely.

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. *tr the consumer stated gm agreed to reimburse the full amount for the previous repair. Updated 02/06/13

I bought my 2003 trailblazer ltz used about 6 weeks ago at 146,000 miles. Today, it will not go over 45 MPH. Due to internal transmission hardware defects. No check engine light, or any warnings were displayed. The problem has been noted thousands of different times between different trailblazer owners and gm refuses to issue a recall on the faulty sunshell gears! So I'm left with a huge safety hazard caused by gm as well as having to pay for their mistake?? I work hard on a tight budget and I'm in the beginning of an 18 month payment structure for this vehicle and cannot afford the $2600 a gm dealership wants to fix an issue they created. So do I drive an unsafe and unreliable vehicle, or work 90 hours a week for the next 3 months to fix my new car?!?
