The instrument cluster on the 2003 Trailblazer malfunctions, causes the speedometer to stop working and you can't tell how fast your going. The malfunctions also occur with the temperature, oil, and gas gauge. Very dangerous not knowing how fast your going. The vehicle needs to be recalled.

This is an intermittent problem with this vehicle.I am 3rd owner. 2nd owner had same problem. The speedometer fails to register correct speed. I am currently using a automotive scan tool to verify actual speed. The most interesting thing about this is it does not occur all of the time. Just when I am getting 19.5 mph or better with a lot of traffic. 1 week ago I had 20 vehicles in back of me. Turns out my speedometer was 20 miles an hour off. I was going 35 in a 55 mph zone.good thing I had my scan tool with me. This is a problem GM has recalled other vehicles for. My question is why the NHTSA is allowing this. These are the same clusters that were recalled for the Silverado. Why even have an Agency as important as this one if it does not do anything about all of these complaints. There are many speedometer complaints.GM says replace the cluster.it still works some of the time so what is the real issue. It should have completely failed by now if it were electrical or mechanical. The owner should not have to pay for this. Why discriminate against Trailblazer owners. Not even an investigation.

Our speedometer quit working last month and started working again a week later. It stopped again 2weeks ago and hasn't worked since. Now I am worried all gauges will quit. I have read many other owners that have same issues with this vehicle.

As I was driving the speedometer just stopped working properly. Now it just dont move at all. This is a problem that has happened to my mothers 2003 Trailblazer too.

- Nauvoo, AL, USA

Summary: Multiple gauges on the instrument panel are malfunctioning. The tachometer is reading 5,000 RPM when the vehicle was in park, and 7,000 RPM when going 15 mph. When I turn the car off the gauge sits at 2,000. The speedometer is clicking up (not a smooth transition to the correct speed). And it showing a lesser speed then I am going. When I turn the car off the speedometer shows it is going 10 miles per hour but will slowly drop down to zero. Both of these malfunctions could are a huge safety concern. I had to pull over on the highway while the instrument panel was showing 7,000 RPM, afraid I was going to break down and ruin my car.

Speedometer, generator gauge, and oil pressure gauge stopped working over three years ago. I checked for a recall but was told there was not one on this model. I was told there were recalls for other Chevrolet vehicles, and kept waiting for a notice regarding the Trailblazer. I am worried now the fuel gauge will stop working. The mileage is now at almost 81,000 miles. The speedometer and other gauge issues create a very hazardous problem, and is detrimental to the safety of me and my children / other passengers. I would like to be notified of a recall notice.

Temperature gauge reads higher than it should and gas gauge fluctuates.

- Mansfield, LA, USA

Speedometer quit working, reads very incorrectly. I am being told by the dealership that its a cluster piece and the price is $600. I contacted GM they will offer no assistance. After researching this on the internet this seems to be a common problem that should be covered under a recall.

While driving, the speedometer will rise and fall erratically. I have been told by my mechanic that the instrument cluster is bad and needs to be replaced. Upon internet research, I have found this is a common problem with GM truck and SUV models in the years 2003-2006. Trailblazer is the only model that GM has not covered in a recall for this part malfunction. How can it be safe to drive and not know what speed I am traveling at? I have an appointment with Chevrolet tomorrow. They will not fix the problem until their technician can diagnosis it...and charge me an extra $99, even though the problem has all ready been diagnosed by certified, experienced mechanic. At the time this first occurred, the speedometer registered 115 mph; my husband estimates he was driving 25-30mph.

We have a 2003 Chevy Trailblazer ltz. The instrument cluster is going all crazy. The speedometer is not working. I see this has been an issue on a lot of the vehicles. We ahve two children and hate driving a vehicle that we don't know how fast we are going. It would only happen once a month at first and now it is every time we drive it. We took it to the dealship and were told that we would have to purchase a new one.

The instrument panel goes crazy. I never know what speed I am going. One day it will work and the next it does not.

- Sand Springs, OK, USA

My instrument cluster malfunctions on a regular basis. The speedometer tachometer and gas gauge all go crazy and register information that is no where near accurate. The speedometer says 60 when sitting still, and gas gauge needle is at 5:00 when there is a half tank. If you start the vehicle and quickly turn it off enough times, the gauges will eventually get back to normal for a few miles, . then go back to strange numbers and process has to begin all over again, don't know if the temp gauge is accurate or not.

None of the dashboard instrument gauges are working in my 2003 Chevy Trailblazer. It began with the speedometer not working properly. It wouldn't work at times then it would suddenly start working and then the needle wouldn't go all the way down to zero and it would start at 10 or 15. I got a ticket once because the trooper said I was going about 70mph & the gauge was reading 60mph. The other gauges began to go out one at a time.

The instrument cluster on my 2003 Chevrolet Trailblazer fails to register the actual readings for speed and/or rpms.

- Bristol, CT, USA

My speedometer broke on my 2003 Chevy Trailblazer. Sometimes it is parked & I am going 50 mph -- sometimes 70....I haven't had it fixed yet - but has heard of several people having the same problem. I feel GM should do a recall -- this is a dangerous thing.

- Erie, PA, USA

For the past 6 months my 2003 Chevrolet Trailblazer speedometer has intermittently worked properly. 90% of the time it is reading a false speed. I never know how fast or slow I am traveling. This is a very dangerous problem that GM should at least acknowledge and recall.

- Elizabethton, TN, USA
