The instrument cluster on my Trailblazer has begun to fail. The tachometer, speedometer and temperature gauge are not always accurate. My vehicle is no longer under warranty and the dealer will charge to repair. After looking online a lot of people have had the same issue. Chevrolet has issued a recall for trucks with the same instrument cluster, but my vehicle is not covered for some reason even though it uses the same hardware.

My voltmeter on the gauge cluster doesn't work. It appears to work when the car is started and jumps to 12-14 volts but slowly moves down to zero and stays there no matter what I do to try and make it move. If I do not know the voltage I am running I wont be able to quickly resolve any problems should there be any serious problem that would show through my voltmeter.

2004 Chevy Trailblazer lt speedometer flicker.

- Parsippany, NJ, USA

2004 Chevy Trailblazer. Instrument cluster (speedometer, fuel gauge, oil pressure gauge, RPM gauge) inop. Gauges consistently don't work. Speedometer can be off 10,20 or 70 mph. Tremendously unsafe. From research, GM knows about this widespread problem. Almost runover by a truck on the interstate. Thought I was going 65 mph on a dark, deserted stretch of highway. Was actually going 35 mph.

- Ogben, IL, USA

I was driving down the highway and looked at my speedometer and it said I was going 80 miles an hour and I noticed all the other cars were passing me! I then noticed my speedometer continuing to rise until it went to 120 mph! I knew I wasn't going that fast. Sometimes it works if I shut the truck off and on until it gets to 0 mph but then it only works for a short period of time and goes crazy again.

The contact owns a 2004 Chevrolet Trailblazer. The contact stated that the instrumental panel gauges, including the speedometer and the odometer, failed. The vehicle was not taken to the dealer for a diagnosis of the failure. The manufacturer was not contacted. The VIN was not available. The failure mileage was 110,000 and the current was unknown.

- Montrose, MI, USA

My odometer one day stopped working and then it would start working again. A few days later my speedometer started messing up. Every time it would do that I would have to stop the car, turn it off and start it up again. I would have to keep doing this until the speedometer went back to working. This worked for about 6 months and now my speedometer doesn't work along with my odometer and the rest of my gauges. The only gauge that does work is my gas gauge. This is a problem Chevy has recalled on other vehicles but not 2004 Trailblazers. They recalled 2004 Chevy vehicles with the same problem but not Trailblazers. This needs to be recalled.

Yesterday my speedometer needle started jumping between numbers rather than moving smoothly. Today it stopped working completely, it stayed below the 0 and wouldn't register the speed at all. I stopped at a Chevy dealership on the way into work and was told the instrument cluster had to be replaced at my cost of about $400. Driving away from the dealership the speedometer started moving slowly (I was going around 55 mph but the speedometer showed 15 - 20 mph.) when I got to work I ran an internet search and found that this is a recall for Chevy trucks but not for Trailblazers. Also found numerous complaint sites with consumers reporting the exact same issue (model year and mileage varied.) obviously this is a widespread issue and should be addressed by a recall from GM. This presents a safety hazard as most consumers don't have the money for the repair cost so they aren't fixing the faulty speedometers which could lead to accidents and fatalities.

The speedometer goes off most of the time you can turn of vehicle then just keep clicking and it will go back to 0 sometimes you star driving and it will go start acting up again and sometimes it stays the way it should be. I think this is a safety hazard you don't know if it is working properly or not and you really don't know the speed which you are traveling. I have request at many places to fix the problem but have been told over and over again that I may spend the money to replace the cluster which is what is causing this problem but it would probably do the same thing. From there knowledge of this problem there are many of these with this problem and I am told if I replace it the other that I replace it with would probably do the same thing. So I am just wondering how can this company get away with letting this problem exist. This is a very unsafe issue and if I cant resolve this I am going to have to trade in for another form of transportation. Please help me with this issue I have kids and a grandchild that depend on this car for transportation and I want them to be safe all the time not just sometimes when the cluster wants to work.
