2004 Chevy Trailblazer instrument cluster problems. Vehicle only has 70K miles. Gauges frequently read incorrect readings. The coolant temperature gauge has taken a deep dive and has pegged out as far as it can go and does not move now. Most instrument backlights have burned out preventing the speedometer and other gauges from being seen at night. Very dangerous. Quick search on internet results in a severe epidemic of this problem with all GM SUV's. a class action lawsuit resulted in a nationwide recall for this problem for all similar vehicles but not the Chevy Trailblazer or GMC Envoy. This seems to be a criminal act by GM. Something needs to be done to protect owners of these vehicles.

While using cruise control at highway speed the speedometer erratically increases. Braking to a stop does not take the speedometer to zero. Turning the vehicle off and restarting sometimes puts the speedometer needle to zero in five mile increments with each cycle. Problem is recurring. Vehicle is taken to the dealer and a "cluster" problem is diagnosed with estimated cost to be around $500. Internet research reveals this to be more than a sporadic problem resulting in the manufacturer recalling a number of vehicle models but not the Trailblazer. A call to GM's customer service department culminates only with a formal complaint being registered... this too being the common end for owners of Trailblazers (according to internet research) the problem is a potential safety hazard as when this occurs without warning one has to gauge driving speed by surrounding traffic.

Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6) as long as your beating up on Toyota, beat up on a company that real makes an inferior product. Gmac. I have been researching this on the web and their are thousands of complaints for this very issue. I have a 2004 trail Blazer. My odometer and speedometer start to slow down and then all of a sudden you look up and I am going negative rpms and negative mph while cruising down the highway. Or the next time it will go fast than I am traveling. Each morning though it starts out working correctly, then after about an hour it goes off again. Once it goes off it stays off till the car has been shut down over night. Loosing your speed while driving is dangerous. GM has been churning out cheap junk for years. Light them up. [xxx]

My speedometer and RPM dial have stopped working on my 2004 Chevy Trailblazer. I called the 800 number and the lady told me that I am not covered for their special provisioning for this known problem. That their special provisioning only covers vehicles 7yrs/70K mileage. I have over 90K miles and they are not willing to cover me. I can"T afford to pay for this to be fixed. I will never buy another Chevy car I can"T believe there is no recall for this issue. There are 1000's of complaints online this should be a recall.

Two years ago my wife and I were driving our 2004 Chevy Trailblazer on the interstate when our speedometer, oil gauge, tachometer, and voltmeter went out. We could not seem to figure out why everyone was passing by us so quickly when we were going the speed limit according to the speedometer. Thankfully we had gps and were able to figure out quickly what was happening. This is a very dangerous problem. If we didn't have gps we would have absolutely no way of knowing how fast we were going. Soon after this happened, the check engine light came on and we were having all kinds of electrical problems with sensors going bad. I have researched these problems and it seems as though we are not the only ones with this problem. GM has not issued a recall on this model for this problem, yet they did for the Suburban line for the same problem. Please, if you can, do something about this problem. We have yet to fix these problems hoping for a recall but have had no luck. We are now in the process of fixing these problems so we can pass inspection. Thankyou very much.

2004 Chevy Trailblazers instrument panel isn't working properly. The RPM gauge fluctuates and often doesn't work which seems to cause the speedometer to respond slowly. I have heard from others with the same issue that eventually the speedometer will quit as will the gas gauge, oil gauge, etc. This is a potential hazard that has not been recalled by Chevy. Other models of the same year have been recalled, but not the Trailblazer.

I've had issues with the odometer, gas and battery gauges for about a year. However, now the odometer drops and the car stalls and shuts off when I go to slow down. The check gauges light came on and off for a second. No other lights are on so I have no idea what this is. Car has about 75,000 miles.

I have a 2004 Chevy Trailblazer. My sister in law has a 2005 Chevy Trailblazer. My RPM dial ent crazy a year ago and now my speedometer is out. I have 82000 miles on it. Chevy refuses to pay for the repair of $500. There are several others with this same problem. I have found many websites. This is and has been an ongoing problem. We need a recall. This is for Trailblazers with the years of 2003-2005. I am not getting my problem fixed and I am sure there are many other instrument clusters that do not work on the highway. GM lost a lawsuit for the exact same year vehicles from 2003-2005 for the Suburban, trucks, Tahoe etc. My vehicle is also considered a truck and I am sure that same cheap part was used in my vehicle. This is definitely a problem part that needs to be recalled. Please help!

2004 Chevrolet Trailblazer that has intermittent lights going out while driving at night, speedometer has stopped working and gauges on panel only work occasionally. Nearly had a wreck when the headlights went out going down the interstate at 75 miles per hour. I did not see a recall. I have seen on line this is a common problem. Has there been a service recall I am unaware of? this is a safety issue. My wife and children ride in this vehicle.

I have a 2004 Chevrolet Trailblazer. The speedometer, the fuel gauge and the tachometer no longer works on this vehicle. When I called the Chevrolet customer service center, to check for a recall, I was told that there was no recall for the Trailblazer. There was however a recall for the exact same problem on the Chevrolet Avalanche, Tahoe and Suburban. I just cant understand why Chevrolet will not recall the Trailblazer for the exact same problem. My speedometer sometimes registers to the point of seeing no numbers on the needle. The gas gauge rarely registers that I even have any gas. I have to keep up with my gas manually and with my trip odometer. I find this very disturbing that Chevrolet will not recall the Trailblazer. What can I do as a consumer to help Chevrolet make this obvious problem right?

All gauges including speedometer on 2004 Chevy Trailblazer stopped working!! thousands of people are having the same problem and it is very expensive to fix and very unsafe to not. GM recalled all kinds of GM's with same problem except for Trailblazer. Please help us with this ongoing problem since GM doesn't want to step up.

Head lights flickering and dimming while driving. Cars think your are trying to get them to stop allowing them to pull out in front of you. The volts drop severely on the battery gauge. This is no way safe and the GM says its normal. No way!!!

The gauges on my daughter's 2004 Chevy Trailblazer will not register correctly. One day they all work, the next day only a few work correctly. One day she is able to tell the correct speed she is driving, and the next day she is stuck on 120 mph. This has been an on-going problem for the last several months. It is the same with the oil pressure, tachometer and gas gauge.
