Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

CarComplaints.com Notes: The Trailblazer emerged from an "upscale trim line" of the Blazer, but there's nothing upscale about its transmission problems or its wonky, unpredictable headlights.

  • 39,993 miles
On 9/25/09, my 2002 Chevrolet Trailblazer stalled and lost power steering when I attempted to make a right turn. When I tried to restart the vehicle, gasoline was caused to spill on the roadway. The vehicle was towed to my local repair shop, and it was determined the fuel filter fitting failed. My vehicle had 39, 993 miles on it at that time. After my vehicle was repaired, further research revealed a recall had been issued under number 02V121000 for the same problem described above. I contacted GM/Chevrolet, and was advised that recall did not pertain to my VIN, nor were there any other recalls issued for my vehicle addressing similar failures. It is obvious that my vehicle should have also been included in the recall mentioned above.

The contact owns a 2002 Chevrolet Trailblazer. If the contact does not unhook the battery post each night, the vehicle will not start in the mornings. She purchased a new battery, but the failure persists. The front passenger side of the vehicle near the tire makes a roaring sound intermittently. Neither weather nor speed were factors. The contact believes that the gas tank is leaking fuel because it is burning more fuel. The vehicle was not taken to a Chevrolet dealer, but was taken to the dealer from where the vehicle was purchased. The mechanic stated that the vehicle was experiencing electrical failure and should be taken to the dealer. The contact was informed that the following NHTSA campaign id numbers did not apply to her VIN: 01V126000 (suspension:front:control arm:lower arm), 03V096000 (electrical system:wiring:interior/under dash), and 02V121000 (fuel system, gasoline:delivery:hoses, lines/piping, and fittings). The current mileage was 165,000 and failure mileage was 150,000.

: the contact stated a fuel odor came from the vehicle. The vehicle was taken to the dealership which was unable to identify the reason for the odor. Afterwards, a NHTSA recall number 02V121000 was issued for the fuel filter. The fuel filter was replaced by the dealership under the recall. The fuel odor persisted after the recall was performed in October of 2002. While pulling out of the driveway, the contact noticed a puddle of fuel where the vehicle had been parked since the previous day. After inspecting the vehicle a different dealership replaced the fuel tank in April of 2005. The fuel odor continued to come from the vehicle.

Fuel line disconnects at the fuel filter while driving. This has happened twice in the past nine months. Strong fuel odor in the cabin. Both times, other motorists brought the fuel leak to my attention.

Gasoline leak in 2002 chev. Trailblazer 87500 miles. Leak arose from rusted steel tubing at top of tank from the sending unit. It seems this is a design or manufactoring fault considering car is only three years old.

The contact smelled gas and it got really strong on 8-11-05. He took the car to dealer to have it checked on 8-25-05. He was treated very badly by dealership. The dealership removed the gas tank and noticed that the two lines on top of the tank were leaking. They told the consumer that he should wash the road salt off of the tank. They stated that was the reason for the leaking. The consumer felt this problem was similar to recall 02V121000. The dealership wanted him to sign a statement, saying the rust and corrosion was his fault, however he refused to do so. Then they said they would not get the part until late Friday, he felt like the dealership was punishing him because he refused to sign their papers. They would not offer him a rental car. He called GM and they advised him to file a complaint with them against the dealership after he got car back. The dealership has had the car one week now and the repairs have not been completed.

The vehicle was leaking gas two months ago, resulting in the replacement of the fuel tank the first time, in last two months, the fuel tank was replaced by the dealer. The vehicle did have a recall dealing with the fuel lines. The fuel line repair was done twice as well. There is still a smell of gas in the vehicle at this time. The dealer states that currently there is no problem with gas tank. The dealer did state previously that there was no problem with the gas tank. And then replaced it. Consumer had to wait for the dealer to get parts to make the repair. The vehicle has been into the dealership at least three times for the same problem. Consumer feels this problem is a result of the recall repair work. The problem first occurred after recall of fuel line was first done. Recall id number 2016.

My 2002 Trailblazer began leaking gas around the fuel filter connection. My guess is a rate of around 5 gallons in 20 minutes. Vehicle kept running. Vehicle has a recall on this with NHTSA campaign number 02V121000. I belieive I had this recall 02016 - fuel filter connect performed by hendrick Pontiac Buick on 6/4/02. The recall has the following decription on the NHTSA database: On certain sport utility vehicles, a fuel filter fitting can become disconnected. If this were to occur while attempting to start the engine, a no-start condition would result and fuel would be pumped out the fuel filter onto the ground. If the fitting becomes disconnected while the vehicle is in motion, the engine would stop due to inadequate fuel supply and cause a loss of power steering assist. If an ignition source were present, fuel leakage from a disconnected fuel filter fitting could result in a fire.dealers will replace the fuel filter quick connect retainers. I examined the filter connect and found the snap-on part of the filter was not snapped into the holes in the hose connection. The snap was actually rotated about 90 degrees. This was not holding the hose in all the way but just enough to cause a major gas leak and to send gas to the engine. I believe the fuel filter connects are a bad design. 1 of 3 things went wrong. 1) the recall was never performed even though the service paperwork said it was. GM needs to replace the connectors because they are poorly designed and can cause a fire/explosion. 2) a certified GM technician installed the connection to the filter improperly. The connection should be designed so that it automatically aligns itself to the snap or does not slide on. This is not a technician problem, it is a problem with the design of the snap connections. 3) the connection worked itself worked loose over time with the regular bumps of everyday driving. In this case, it is also a problem with the design of the snap connection.
