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.

The problem is on my 2004 Chevrolet Trailblazer. The entire dash gauges malfunction occasionally, from speedometer to battery gauge to oil pressure gauge to water temp gauge to RPM gauge. I am one of thousands of Trailblazer owners who have this problem not only in the usa, but around the world, just read the forum on edmunds.com and you will see. I usually temporarily fix this problem but turning the vehicle on and off until the gauges fully reset, but that puts a lot of strain on the starter. Please open an investigation to trigger a recall because Chevy dealers want us owners to shell out $100 to figure out the problem we already know and then want to gouge us for another $700-$1000 to fix. That is totally uncalled for, for a part on the vehicle which is vital to drivers, the instrument gauges.

Speedometer stuck/instrument panel on christmas day we were traveling to families house to celebrate the holidays. 1.5 hours into the trip, the speedometer went crazy and was at 90 when we were going 65. Pulled over and when we stopped it increased to 120 mph. Since we had another 3.5 hrs of our trip and it was unsure exactly what was wrong (since there were no dealership/service stations open), we turned around and went home. Nice christmas that we had, not. On Monday (the next day the dealership was open) I called to get an appt. And couldn't' get in until Tuesday. Went in Tuesday and of course charged me a diagnostic fee, when I could tell from searching the internet what was wrong (by now the speedometer was straight down between 0 and 120). 1.5 hrs later the dealership tells me it is the instrument panel (surprise, surprise) and that they would have to order since they have none in stock. It would take 4-5 business days. The earliest we're looking at getting is next week, now 10 days past the day it happened. I asked the dealership for a loaner and they offered me enterprise rental for $40/day (my expense). They could offer me nothing else, sending me on my way. Ok, Chevy...since this is a huge problem, the least you could do is stock dealerships with the panels, especially since this is a large dealership. It is not safe to be driving around with no working speedometer. Did I mention this is also my vacation week....nice, being stuck at home cause you have an inoperable vehicle. Chevy needs to step up to the plate and make this right with their costumers. I have been a faithful owner since 1994. A $415 part/plus labor is ridiculous when there have been so many complaints, you need to recall this.

2004 Chevy Trailblazer has instrument cluster failure...tachometer stuck at "maximum", and dealer reports all the gauges will be unreliable, shortly. Have read dozens of these complaints, but GM (who* saved) won't make it right?

I own a 2004 Chevy Trailblazer; the tachometer, speedomoter and other gauges started to fluctuate and now the speedometer never works properly, the tachometer comes and goes and now the oil gauge is not showing the proper reading (I had it checked out to make sure I had oil and no other issues). I am told a new cluster board is needed at the cost of $600-$700. Chevy is more than aware of this being a "typical/known" issue and I cannot understand why there has not been a recall on this forcing them to replace these cluster boards. I have purchased a gps which has the speedometer option so I know at what speed I am traveling; but if the oil and gas gauges go; I have no choice to fork over $6-700.00. Why is Chevrolet not being held accountable for faulty equipment they installed in their $37,000 vehicles" who else can I go to in attempts to get someone's attention to get Chevrolet to take responsibility"

I bought a 2004 Trailblazer with a factory installed tow package, including electric hookup. When I hooked it to a travel trailer, the tblazer sent to charge to the trailer for battery charge, interior lights, etc. The dealer, gold motors in newport, Oregon, said there was no problem. However, it still refused to work. I took the car to a local mechanic. He discovered several wires in the box housing the wiring manifold at the front driver side of the engine were cross-wired. He straightened it out at the cost of two hours labor. If this is the standard quality of GM quality, they should be allowed to go bankrupt.

The voltage gauge and RPM gauge had since stopped functioning and the speedometer would fail intermittently. The vehicle was not repaired. The failure mileage was 60,000 and the current mileage was 100,000.

Fuel, engine temperature, tachometer not displaying correct data. Fuel and temp gauge displays show needle pinned (below lower half of gauge) and tach sometimes does not work or shows zero at idle. This seems to be a common problem and occurance with this make and model. Obviously, the most important is the gas gauge... not knowing exactly how much fuel is in the tank is hazardous and annoying. I have to "guess" when to fuel up, especially on longer trips.

Trailblazer

  • 84,000 miles
I own a 2004 Chevy Trailblazer and the speedometer has progressively gotten to the point of being completely inoperable. The first time I noticed the speedometer read 120 mph when I was driving on the highway were the speed limit was 55 mph and I was driving with the flow of the traffic. I turned the car off and the speedometer still read 50mph. As of a month ago my fuel, oil, battery, and temp gauge are all inop; the needles never move. With this my battery, seatbelt, ABS, and parking park stay illuminated. This is a safety concern because I never know how fast I'm going, how much fuel I have, if my car is running hot, I have no warning indication of anything going on with my vehicle.

Oil pressure gauge became unreliable and had different reading each time the car was driven. Most recently the gauge needle moves past the upper limits of the gauge and points straight down at the fuel gauge. Two days ago, the speedometer began acting in the same erratic manner and will give various readings including exceeding 120 mph and will point straight down at the steering column. It may read anywhere from 30 mph to 75 mph at various time when the vehicle is parked and the ignition is off. Bottom line is that I am no longer to check my speed in comparison to speed limits or speed warning signs when in mountainous terrain.
