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.

Print this page 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.

I have a 2005 Chevy Trailblazer, on 1-20-08 the speedometer failed, it stuck on 80 + mph ( when it should be at zero ) and would only go higher in motion. On 1-23-08 my wife took vehicle to phillips Chevy in frankfort, ill. We are told that in instrument cluster is the problem and needs to be replaced, we are not covered under new car warranty because we have exceeded the mileage. I checked with Chevy to see if there was a recall in force and there is not. It seems that there are numerous other GM and Chevy owners for various years that have same problem and there is a law suit in Washington and Oregon that are seeking class-action status. I feel that this has been an ongoing problem with GM and Chevy and that they should issue a recall to repair or replace as needed.

Speedometer gives an inaccurate reading or sometimes stops working altogether. This problem began 2-3 weeks ago and from other Trailblazer owners that I have discussed this with online it is a very common problem. I didn't realize that the speedometer was functioning improperly until it became very obvious - it was registering 30 mph when I was traveling with the flow of traffic on an interstate freeway. When the vehicle has been turned off and sits for a while, the speedometer seems to reset itself and works properly again for a while, then the problem begins again. From what my research indicates, it is a bad stepper motor that causes the problem, which requires specialized tools and expertise to replace. The cost is in the hundreds of dollars. Given that this is such a common problem and compromises the safety of the vehicle, I strongly feel that this issue should be addressed by NHTSA. Thank you.
