Are you guys (gals) reading the complaints centered around 2004 Trailblazer and the problems with electrical systems "instrument cluster" malfunctions? I have!! there are one after another complaining about either mis-readings or no reading of instrument gauges! my 2004 Trailblazer has 70M miles and the RPM reading is mis-reading as well. Get GM to recall this vehicle just as they have been forced to with other passenger & truck models. Speedometer and gauge mis-readings are a very serious hazards to driving and safety to the public. What else do you need to take GM on!

The contact owns a 2004 Chevrolet Trailblazer. The contact smelled a strong odor of gasoline coming from the vehicle. In addition, the engine warning indicator illuminated sporadically on the instrument control panel. She took her vehicle to the dealer and they stated that fuel vapors were leaking and collecting on top of the module. The failure caused fuel to spill onto the ground. The contact would have to pay $1,300 to have the vehicle repaired because it was not registered in a salt belt state. Secondly, she noticed that the gauges on the instrument panel were inoperative and displayed inaccurate information. The dealer stated that the VIN was not included in the manufacturer's recall for the instrument control panel; therefore, she would have to pay $550 to repair the component. Currently, no repairs have been made. The failure mileage was 66,000 and current mileage is 73,000. Updated 3/11/09 updated 03/13/09.

I have an 04 Trailblazer with only 43000 miles that has developed an obvious recurring problem with the gauge cluster failing and reading inaccurately. I realize that investigations have showed no deaths or injuries due to this failure however does it not produce and increased safety risk and should be recalled" what is being done to correct this besides owners having to shell out over $500 for the repair"

The engine temperature and battery charge meter are inoperative, the needles point down (off the gauge). The speedometer and tach gauges also work intermittently. The dealer offered to replace the entire instrument cluster for approx $700, but this part is not under any kind of original or extended warranty. This same part was recalled on several other GM models, but not including the Trailblazer. Not having a temperature gauge and speedometer has potentially seriously dangerous consequences, GM needs to recall and replace this part immediately.

I have a 2004 Chevy Trailblazer. The speedometer is not reading correctly. I can be at a stop light and it will read I am doing 90mph. I do believe this should be a recall by reading all the complaints on this problem. I don't have the extra money to have this problem fixed. I do believe it should be the manf. Responsibility to fix it.

The speedometer on my 2004 Chevrolet Trailblazer displays a reading of 120 mph and over when traveling at normal speeds on highway (middle lane, many other cars passing on left). This was reported to a car dealer who informed me that the instrument panel needs to be replaced (at my cost).

I own a 2004 Chevy Trailblazer with 56K mileage. In December 2008, the speedometer stopped working. I would be at stop, and the needle showed 80 mph. I brought the car to the dealership right away and they told me that the cluster needs to be replaced - but they needed to order the replacement part. I finally got it fixed a week later and it cost me approximately $525. Now, for the past two weeks, the engine had suddenly shut off in the middle of driving. The "reduced power" & "check engine" lights came on. Both times, it started back up after I parked it, turned off the ignition, and re-started. But after the second time, I brought it in to the dealership. I had to have the accelerator pedal replaced. Cost me approx $360. These two issues are very concerning with me because if I were driving at higher speed (65mph) in the middle of the highway (instead of 30mph around town), I could have died from contacts with other vehicles because my vehicles stopped functioning!

All within the last few months I have had to replace the complete drivers side low beam headlight and electrical pigtail because it caused an electrical short that burnt the wires. A few weeks later driver's side rear stop light quit working, I had to replace the bulb, next, the blower motor won't work on 5...and it won't transfer from defrost to, I am currently replacing the blower motor resistor and the red wire is fried because it appears not to have been "pushed" all the way in from the factory, (I have taken a picture of it)and now I have to "replace" the entire wiring harness...I'm really starting to hate Chevy...especially when I browsed through all the complaints... is there ever any resolve? I think most of the issues I /we have are all safety issues...would you handle things differently on your end if someone you know and love was in this type situation where they were concerned for their safety as well as the public's safety!!!!

The accurate speed could not be determined due to the failure. The dealer stated that the repair would cost over $500. No repairs have been made to date. The failure mileage was 60,000 and current mileage was 80,000.

The speedometer is malfunctioning. It will sometimes read 110 when I am only going 20. I have talked to a mechanic and they said it is the instrument cluster and it will cost about $500 to fix it. He said he has had several complaints for this same issue on his model. I have seen several complaints on it on the internet and I think a recall should be issued. Sometimes the speedometer stops working at all and this is very big problem. I don't think I should have to pay to get this fixed when it is a manufacturer issue and I think a recall should be issued. Please help....

Speedometer provides false and incorrect speeds. Happens at normal road speed or while in park. Sometimes reads high or low.

RPM gauge failed, then the oil gauge and now the battery gauge. Why won't they have a formal recall and Chevrolet pay for it" they did have a bulletin but the Trailblazer was not included. I would like them to pay for it"

2004 Chevy Trailblazer dashboard gauges and speedometer work intermittently. Electrical problem requires a new instrumentation cluster, which runs $600. While searching online, I've noticed that there are many others who experiencing the very same problems with their Trailblazers. Faulty gauges are a nuisance, but a speedometer malfunction is an entirely different matter. I'm am checking with Chevy tomorrow concerning an existing recall, but was not offered a recall repair when the dealer originally troubleshoot the problem. If no recall exists, it should. A trend exists that needs to be examined and corrected by GM.

The contact owns a 2004 Chevrolet Trailblazer. While driving 40 mph, the contact made a stop and noticed that the speedometer read 100 mph. In addition, the fuel gauge dial failed. She does not know if the gas tank is full or empty. She will take the vehicle to the dealer to be diagnosed. The failure mileage was 60,000 and current mileage was 61,100.

About 10,000 before the factory warranty ran out, the speedometer got stuck at about 60mp so it read that much higher than actual speed. After a few times of starting the vehicle the speedometer reset itself, so when we took it in to the Chevrolet dealership they couldn't duplicate the problem and they wouldn't cover the problem. It eventually kept getting higher and higher until it was stuck and didn't read the speed at all. Now the dealer says it is a faulty instrument cluster and want to charge me $500+ to fix. I believe this is a serious safety issue and Chevy should issue a recall on the 2004 Trailblazers.

The dashboard gauges began displaying incorrect information followed a day later by complete failure. I know others with the same problems. There is no recall for this error. There is no way to determine the speed of the car. This is a very expense and common error for the Trailblazer.

Tachometer and speedometer not working correctly. Tach works for a short time then drops to zero. Speedometer shows 30mph =/- while stopped. While moving it shows 30mph+/- over actual speed according to my computer scanner. Contacted GM and they said there was not record of this type of complaint and it is not covered under warranty.

I have a 2004 Chevy Trailblazer, the RPM gauge stopped working and it has slowly progressed to the oil gauge and now the speedometer reads way off the charts. I see through some internet searching that this is a recurring problem with these vehicles. I have not had this problem repaired as of yet, as I feel with this being such a safety issue and such a repeated problem with the Chevy. Trailblazer that Chevrolet should issue a recall.

I own a 2004 Chevy Trailblazer, both the tach and speedo operate erratically. The speedo is of particular concern, the erratic reading indicates the wrong vehicle speed, mant times is reads 20 - 40mph to low which can lead driving hazard. This is significant safety issue. Research on the internet shows this a very significant problem on these vehicles, with the incident rate a magnitude higher than normal / acceptable failure rates.

2004 Chevy Trailblazer - intermittent flickering of exterior lights. Headlights sporadically flicker during normal night time driving. Flickering may occur multiple times during trip and then not occur again for several weeks. Problem began at approximately 50,000 miles. It is very frightening and is probably very distracting to other drivers.
