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 6-cyl

  • 67,000 miles
The contact owns a 2005 Chevrolet Trailblazer. The contact stated while driving at approximate speeds of 60 mph, the vehicle stalled. The fuel level gauge indicated there was half a tank of fuel in the vehicle yet the tank was empty. The failure would occur intermittently and because she was unable to determine the exact amount of fuel in the vehicle, she would fill the tank completely within every 200 miles. The vehicle had not been to the dealer for a diagnostic or repairs. The approximate failure mileage was 67,000 and the current mileage was 68,000. Updated 12/02/10 updated 12/07/10

Fuel gage has failed and does not work... failed at 38000 miles... purchased car December 2005 with 13,500 miles from dealer...current ownership two years... low fuel light stays on even when tank filled...gage will sometimes vary between "E" and 3/4 full... most of the time staying on "E",...absolutely cannot tell how much gas is in car from the gage. More than one person drives the car and it is going to leave someone from my family stranded on the road at some point. I went to the dealer and complained and was told that it would cost between $350 and $500 to repair, that the fuel sending unit has failed...that gas tank would have to be dropped to replace... however "just keep driving the car until the fuel pump fails and replace the pump and the sending unit assembly at that time, saving the extra cost..." "keep track of your mileage"...which varies between city and highway driving... not exactky what I want to hear!!!

In recent months my fuel guage indicator light is showing low fuel even after the vehicle has been fueled to capacity. After speaking a with several other Chevy Trailblazer owners, I have discovered that they are, or have experinced the same problem. I was advised by one of the owners that there was a problem with the fuel sensor. The cost to replace this item through the dealership was between $350-$450. After reading the complaints on this website and speaking with other Trailblazer owners. One can conclude that this it a factory, workmanship defect; and the consumer should not be held responsible for repair or replacement. Finally as of this complaint I have not repaired the fuel sensor.

Trailblazer 6-cyl

  • Automatic transmission
  • 42,500 miles
The sending unit for the fuel gauge on my 2005 Chevy Trailblazer failed and had to be replaced at a cost to me of $400. When my repairer called the dealer for the part, he was told he had to wait a day as the part was not in stock, because the had sold out of them and there had been a "run" on this individual part. This would lead me to believe that the part failure is not random but that it was defective and others were experiencing the same problem as I.
