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: It would be ill-advised to blaze any trails with the 2004 Trailblazer. Its faulty fuel gauge could leave you stranded.

Trailblazer 6-cyl

  • 75,476 miles
After driving my ls Trailblazer to the store, I got back in to notice the speedometer was no longer resting at "0". this was before I even started the vehicle. It was sitting at the "55" point! upon starting the vehicle, the gauge did not move back to zero. So as I drove away, going no more than 10mph, the gauge suggested I was going 65! I was scared driving home because I did not know my exact speed. Upon getting home and shutting off the vehicle, I noticed the gauge rested at the "50" point. So I turned on the vehicle, then quickly turned it off. The speedometer was now resting at "45". I continued to quickly start and then shut off the vehicle, eventually working the gauge back down to zero. But this does not seem like the right thing to do. There is obviously something wrong. In the past, I have had smaller scale incidents with the tachometer gauge. It would zero itself at 1 or 2 rpms, thus indicating my engine was revving higher than it actually was. Moreover, a couple times my fuel gauge was pointing outside of the E to F range! there is something seriously wrong with the electrical system. GM, you need to recall this and fix it please.

While taking my girls to school my speedometer reading was 50mph faster than I was actually going and my tact was not registering at all. When I stopped the car I turned engine off and restarted the car and neither gauge works at all and hasn't in over a year. I took the vehicle to my local dealership and they want $800 to fix it and said it was a malfunction in the cluster and I have checked and it is a severe problem with this make and model. I have been driving without these gauges working and judge my speed with the traffic, but I am a single mom with limited resources and purchased a GM vehicle because of the safety reports. I feel that with all of the other same complaints does it take a loss of life to get this issue resolved.

I have the same problem that an earlier blogger as, all my gauges are stuck, the speedometer is stuck, the oil gauge stuck, gas gauge stuck, I think GM needs to take control of their problem and correct it, not just say it's not a problem they will not fix. There needs to be a recall for this problem pin the Trailblazer trucks.

I have a 2004 Chevy Trailblazer and the cluster is going bad. Finding out that I'm not the only one that has this problem. I had the same problem with my Chevy Avalanche and it was recalled. I think that this a problem while driving. I think someone should do something before someone gets hurt. Because the gauges go out the on and while driving. It could hurt a young driver that doesn't what to do. GM knows the problem but will not do anything about it. It the same problem that they did a recall on with the trucks. So I think they should fix this problem. So could you please help before someone gets hurt bad over this problem. Thank you please help!

Fuel gauge has been fluctuating wildly for a couple of months, generally reading empty (even after fill up) but occasionally full (when a fill up is needed). Dealer said fuel gauge sensor was bad & that it would be approx $900 to fix. Looking into the problem online I see there are thousands of people with the same problem.

The stepper motors in the instrument cluster have failed. This is an extremely common problem and people are now making a living off of charging for the repairs because GM is refusing to issue a recall.

The driver's side window relay switch is bad. I have had several quotes from dealerships and looks like the cost is around $400. (for them to replace and reprogram). There is a huge safety issue if you cannot roll down your window on the driver's side and roll down and lock or unlock any of the doors or windows from the driver's side as well. I have read many complaints on various websites from consumers with the same problem. With the majority of these switches going bad, they need to recall this, as it is very costly andnot at all safe. Especially if an officer needs to approach you and you have to open your door first. That could lead to an unsafe incident toward yourself as well as any law enforcement agent. If you can please address this issue, it would be greatly appreciated. I have researched any recall on this and have not had any luck. Thank you for your time in addressing this issue.

Instrument panel gauges malfunction and show improper readings. For instance tachometer shows 5000 RPM at idle. Alternator gauge is off the scale. Temperature gauge is also showing false reading. Oil pressure gauge is also false. Incident date is approximate. Individual gauges failed over time.

Trailblazer 4WD 6-cyl

  • 53,000 miles
My 2004 Chevrolet Trailblazer 4X4 V6 is experiencing some instrument panel cluster problems. This is the second time as I had the instrument panel cluster entirely replaced once already. The fist time, the tachometer stopped working and the speedometer malfunctioned showing incorrect speeds at different times, including showing 80mph when sitting still in the driveway. Now the instrument panel has malfunctioned again. Now my battery gauge, fuel gauge, oil pressure gauge, and temp gauge stopped working and and are at zero as if the car is off. Most of my warning lights are on also. The ABS, seatbelt, battery, and parking brake lights stay on. Also, the gear indicator light telling me if I am in P, R, N, D, etc no longer highlights the gear I am in and the cruise control light doesn't come on when I engage the cruise control. However, I would say once out of every 15-20 times I drive the car the instrument panel and gauges work flawlessly. Obviously this time it is not the motors of the gauges that are the problem, but something power and/or electrical. I'm worried about knowing how much gas I have left and, more importantly, what my speed is, whether the engine temp is ok, and whether the oil pressure is normal.

Trailblazer 6-cyl

  • 84,000 miles
The speedometer on my 2004 Trailblazer operates very erratically. At times it does not work at all at times it registers way slow or way fast. This to me is a major safety issue. If driving on snowy roads you can not tell how fast your wheels are spinning and this could cause loss of control of the vehicle. Or another scenario, traveling on the interstate and the miles per hour is registering between 5 and 10 mph less that you are actually traveling. This could pose a rear end collision problem as those traveling behind you may not notice that your speed is slower. A properly functioning speedometer is a vital part of being able to drive the vehicle in a safe manner, not only for your safety but for those around you. In searching the internet this seems to be more of a "common" problem than what one might realize. General Motors should be held accountable for this problem, as a properly functioning speedometer is an important safety feature. The same as brakes failure, throttle sticking, fire hazard or any other myriad of items on a vehicle are related to the proper and safe operation beyond the operators control. Please look into this. Thank you
