Instrument cluster panel failure causing speedometer to not work creating a safety hazard- GM will do nothing about it.

The contact owns a 2004 Chevrolet Trailblazer. The contact stated that the speedometer stopped working and registers 65 mph while the vehicle is parked. The failure prevents him from knowing how fast he is traveling. The dealer has not been notified. When the contact bought the vehicle, the spare tire wrench under the rear bumper was stripped so that it could not be lowered. He had a mechanic examine the spare tire wrench and was advised to take the vehicle to the dealer. The current mileage was 66,000 and failure mileage was 62,000.

The contact owns a 2004 Chevrolet Trailblazer. The contact stated that the speedometer, water temperature, and fuel gauges have all malfunctioned. The mechanic could not repair the vehicle due to the lack of proper machinery. The contact feels that this is a safety issue because the gauges do not register. As a result, he does not know how much fuel is in the vehicle, the engine temperature, or how fast he is driving. The current mileage was 96,000 and failure mileage was 70,000.

The speedometer and tachometer in my 2004 Chevy Trailblazer stopped working a few months ago. I have made several attempts to work out a solution to this problem with Chevy, to no avail. I took it to the dealer to run a diagnostic test as requested by Chevy, the test showed the cluster is bad. Over the course of several conversations with Chevy, I was told they are aware of an existing problem with the clusters, but are not going to do anything about it. I did a lot of research about this on the internet and have found that I am not the only one with a faulty cluster. This seems to be a common problem with the 2003 & 2004 Chevy models. Chevy admitted this to me, and are fixing "some" models, but the Trailblazer is not one of them. I really don't understand! there are two class action suits, that I found on the internet, Chevy is fixing the vehicles in those two states, but what about the ones of us who don't live in those states? I have not made the repairs to my vehicle, I bought a gps to keep me within the speed limit. Any help you can offer is appreciated!!! thank you for your time.

We are having the same safety issue as so many others are having with our 2004 Trailblazer. The gauges do not work properly...particularly the tachometer and speedometer, but also include our headlights and radio which both occasionally flashing out for a second or so. This started happening around 47,000 miles. And since we are filing this complaint we may as well mention how our rotors and brake pads completely broke down at around 48,000 miles.

While driving my 2004 Chevy Trailblazer, with mileage of 52,198, I noticed that the speedometer was not registering accurately and then, within 30 minutes, the needle of the defective speedometer, permanently settled to zero; even though I was on the highway and traveling with the traffic flow of 60 M.P.H.

I have a 2004 Chevy Trailblazer that has gauge problems, most notably, the speedometer. I have a 2004 Chevy 2500 truck with the same problem. The truck is covered on a recall but the Trailblazer is not. I feel that the Trailblazer should be covered.

The speedometer on my instrument cluster started to fail, overstating speeds by 10 to 20 mph and sticking at times. At this point (Feb 2009), speedometer is almost permanently stuck at 90 miles per hour or more.

I have a 2004 Trailblazer. At 30,0000 miles the speedometer stopped working while I was driving on the freeway. I worked occasionally but now is totally nonfunctioning. The car only has 35,000 miles on it. I have been told this is not an item covered by any warranty. This is a major safety issue and there needs to be a recall.

My speedometer stopped working around 50 thousand miles, my tachometer died just after, Chevy dealerships recalled the trucks, but not the trail Blazer, for a 2004 XL model this is not right and to replace the moguler is about 400. Plus installation, my has many people complaining of this same problem, this is a major safety issue!

  • 62,000 miles
For the past several months we have been experiencing difficulty with the gauges on our 2004 Chevy Trailblazer. Initially the speedometer was malfunctioning but we found that if we stopped the engine and restarted it, it would reset itself. Over time, it has been unable to reset and currently reads 120mph while idle. Additionally, the other gauges have begun to malfunction as well. The gas gauge does not work at all and the battery and oil temp gauges work on occasion. It is our understanding this is a problem on Chevy Trailblazers from 2002-2004, however a recall on the parts have only been called on the 02 and 03 models, not the 04. Although we have not had any accidents or received any tickets from this product failure, we have ran out of gas and had to use another device to keep track of our speed.

I purchased a 2004 Chevrolet Trailblazer in 2007. After a few months the speedometer started to stick. Soon after the rest of the gauges have gone completely inoperable. I have no idea how fast I am going or how much gas I have left or how hard the engine is working. No none of my rear lights function. I have gotten pulled over 4 times and I fear its a matter of time before a the rest of the electrical system completely shuts down and an accident occurs. I have seen a multitude of complaints but no recall. I purchased the vehicle with 41245 miles on the odometer and now reads 76411. Impossible since I was deployed to iraq for 8 months and have owned the vehicle for less than 2 years without major commutes.

  • 55,000 miles
At approximately 55,000 miles I noticed my speedometer clicking at 5mph intervals. The problem persisted when I was pulled over going 10mph over the speed limit when it appeared I was going the posted speed. The problem got worse when my speedometer started sticking, and finally rotating all the way passed top speed back to zero. This malfunction spread to my tachometer where it shows I am traveling at more than more than 11,000 rpms at cruising speeds on the highway. Then my gas gauge began to malfunction. The reading put me at nearly 200% capacity, making it impossible to know how much fuel I had. So I began using my odometer to gauge my fuel until I noticed my odometer reading 2-4 tenths of a mile every 1/10. I have already received 2 speeding tickets due to this problem. It is only a matter of time before I am stranded out of gas. I see there are plenty of complaints from consumers with the same problem. I have no idea of any related deaths or injuries due to this problem, but this is obviously a GM defect not related to regular scheduled maintenance that should be taken care of by the manufacturer. Not only can this issue only be repaired by a dealership at outrageous fees (estimated $550), but their defective part is now giving a faulty odometer reading which against Missouri state law.

First when I bought my certified pre owned trail Blazer the tachometer went out and pointed straight down then a couple months later my whole instrument cluster went completely hay wire. The speedometer, tach, oil pressure, gas gauge, everything needed to effectively drive has gone wrong. I cannot tell if I am speeding, if I am out of fuel, if my engine will over heat and this is all very dangerous on the highway, I worry constantly. I have taken it in to be fixed but cannot afford it because I am paying for my college. This is a very common problem with these vehicles and GMC/Chevy should do something to fix this safety hazard.

It started out with the tac not always working. Now the speedometer does not work. When I am on the interstate it usually reads less than actual and when I am in town driving it often indicates a higher speed. I believe there are now problems with the gas gauge.

Trailblazer 6-cyl

  • miles
I have a 2004 Chevy Trailblazer ls V6 2wd. My speedometer went out on me while I was driving. At one point it was stuck at 120 mph. I was told by GM that they have the same problem with other model and made a recall on them. When I asked if there was a recall for the 2004 model they told me that there was not because not enough people complaining. To me it sounds like they know it's a problem but will not do anything about it.

Speedometer of 2004 Chevy Trailblazer is broken. It works sometimes, but recently I am clueless on what speed I'm going. I might go 55 mph and it reads 120 mph or I'll go 40mph and it'll read 10mph. "?"
