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. 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.

The contact owns a 2005 Chevrolet Trailblazer. While driving approximately 25 mph, the brakes failed. The failure occurred intermittently for three years.

The window regulator, battery cable, tank level sensor, clutch fan, serpentine belt, tight outer tie rod, hood latch, water pump, were all replaced. Also, the rotors were warped, due to rust by climate, the rear brakes pads were worn and had to be replaced. The front rotors were machined. There was an intermittent surge after accelerating from a stop. There was a squealing noise coming from the brakes. The passenger side brake lights were blowing out. The tail light circuit board was replaced. The check engine light illuminated, due to a faulty emission vent valve and hose assembly. The ABS was engaging, when coming to a stop. Updated 10/01/14

Trailblazer 4WD 6-cyl

  • Automatic transmission
  • 70 miles
The contact owns a 2005 Chevrolet Trailblazer. Since purchasing the vehicle, the headlamps flicker or dim while driving, similar to a power surge. The dealer was initially unable to duplicate the failure. When the failure was able to be duplicated, the dealer was unable to make a repair. At the end of September of 2007, the steering column made a sparking sound and the dealer could not duplicate the failure once more. On September 20, 2007, the radio and all the components on the instrument panel failed intermittently. The vehicle had to be turned off and restarted for them to eventually operate again. In addition, the dome lights would remain illuminated. The driver's side door latches were replaced twice. The rear hatchback latch was replaced twice. When the key was removed from the ignition, the key buzzer would continue to sound. On January 25, 2008, the rear wiper motor was replaced and failed again on March 4, 2008. The current mileage was 36,182 and failure mileage was 70. Updated 4/2/08 the consumer stated the emblem on the rear tailgate loosing color, brake pads and rotors are worn. Updated 04/02/08

Trailblazer 4WD 6-cyl

  • Automatic transmission
  • 61,000 miles
On 04/06 my wife was driving our 05 Trailblazer that we have had about a year and the dealer already had to replace the engine, and now the brakes just went completely out without warning. It caused her to rear end another vehicle luckily no one was hurt. The dealer we bought it from refuses to work with us they told us they already put the new engine in it and they didn't have to do it. If they didn't have to do it then why did they keep it 2 months right after we bought it? I took it to a mechanic near where we live and he replaced the master cylinder for the brakes and they work fine now. The dealer said that it was out of warranty and we would have to pay 75 dollars for them to tell us what was wrong with it. This is the worst vehicle I have ever owned. As soon as you fix something, something else major goes wrong with it. You name it and I have probably had it worked on in this vehicle. I called the dealer and tried to work with them and just replace the vehicle with one I could put my wife and kids in without worry if something else is going to go wrong with it and someone gets really hurt or killed. I just need help trading this vehicle in so I can get a reliable form of transportation for my family. Just want the dealer to work with me and cancel this loan out and I will gladly buy another vehicle.

Trailblazer 4WD 4-cyl

  • Automatic transmission
  • 1,000 miles
The contact owns a 2005 Chevrolet Trailblazer. When driving down a hill or on level ground vehicle will just die. It is very hard to use the anti lock brakes or steer the vehicle. The vehicle has been taken to the dealership twice. The vehicle is still under warranty. Last week stopped at cross traffic applied the brakes and they did no stop the vehicle.
