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 2002-2007 Chevrolet Trailblazer is known for many things, but perhaps it is most famous for its faulty fuel gauge.

This gauge flip-flops more than a politician during election season. Some report that the gauge says "empty" after a fill-up, while others report the gauge says "full" when they're running on fumes. Either way, there's one thing everyone seems to agree on: the darn thing is just wrong.

Following hundreds of complaints and a few accidents allegedly caused by the malfunction, the National Highway Traffic Safety Administration (NHTSA) opened an investigation into the issue in May 2011. Unfortunately for frustrated owners, no recall has been announced.

Trailblazer 4WD 6-cyl

  • 32,000 miles
Have a 2006 Chevy Trailblazer that only has 36,000 miles and the fuel gauge is not working properly. If I fill it up, it will show empty and the empty alert will start sounding while the light comes on. Eventually it will start working after about 80 or so miles. Then when the tank gets to about 1/4 it starts acting up again. I have seen many complaints, in fact hundreds if not thousands, of people having the same issue online.

Trailblazer 4WD 6-cyl

1.fuel gauge on our 2006 Chevrolet Trailblazer ls sport with 6 cyl. Engine became erratic going up and down without relation of how much gas was in the gas tank. This started when vehicle mileage was below 40,000 miles. 2. now the fuel gauge always reads empty, and we have to go by trip mileage to determine when to fuel up. Once June 18, 2011) when we hadn't filled the tank fully, the distance on it was misjudged and ran out of fuel on a main thoroughfare during heavy traffic. Thankfully an accident didn't happen. 3. we had checked the internet about this problem and found it wasn't rare, but quite prevalent on our vehicle and similar ones, due to defective fuel sending units having contacts corrode. We put in a bottle of GM fuel treatment, with no change. The expense to replace the combined sensor/fuel pump unit that is located in the gas tank isn't worth spending as the replacement part is identical to the original and the problem will happen again. If the fuel runs out in an intersection or rush hour traffic a crash could result that could cause injury or death..
