Problems with 2004 Chevrolet TrailBlazer ELECTRICAL SYSTEM

I have a 2004 chevrolet trailblazer. the instrument panel only works intermittently. i have checked the internet and this seems to be one of the most numerous complaints. i feel as if this present a safety hazard. since this is your job to protect the public from defective automobiles i feel you should investigate this matter. thank you. randall saltink

Tachometer and speedometer on my 2004 chevy trailblazer do not work. problem started intermittently at approximately 60,000 miles. initially the problem only occurred after using cruise control. however, the vehicle now has over 70,000 miles and both gauges do not work at all. vehicle hasn ever been in any accident to cause this issue. speedometer dial now reads past 120 mph even when car is stopped. fuel gauge also has recently started to fail. *tr

The instrument cluster for the dashboard began to fail. first, the rpm gauge no longer worked. after a little time had passed, the temperature gauge failed, then the battery gauge, then oil and gas. when various mechanics were asked about the problem, i was informed that it was a very common problem for trailblazers and similar vehicles manufactured by gm. when gm was informed of this, they told me it was not under warranty and thus i would be responsible in fixing it. *tr

With driving home my speedometer starting screwing up. now it doesn't work. come to find out the cluster is bad. my dad has a 05 silverado and that cluster was recalled. why not the trailblazers with the same problem. *tr

The tachometer needle points straight down and does not respond to engine speed. according to information online, the problem will progress to the other gauges inside the instrument panel of my vehicle. it will be a safety issue when the speedometer stops working. gm has made repairs for some models but not the trailblazer. *tr

2004 chevy trail blazer, speedometer, tachometer and gas gauge all failed while on the road. a speedometer is a must. i saw on the net where this is not an uncommon problem and the site said that gm has already won a law suit but has not issued a recall. *tr

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. *tr

Headlights continually burn out. replace every month! just replaced on 2 days ago and already out again! speedometer does not work. *tr

Tl*the contact owns a 2004 chevrolet trailblazer. whenever the contact drove the vehicle at various speeds around 45 mph, she noticed that the instrument panel illuminated intermittently. the dealer informed the contact that the failure could not be reproduced. the current and failure mileages were 70,365. updated 05/13/10,*jb

While driving along my tachometer and speedometer on my 2004 chevy trailblazer dip below zero. i took it to my mechanic who said the electrical is shot in the dashboard area. my vehicle has to be running for 30 min or more for it to act up. if i leave cruise control on the needle stays ,once cruise is turned off i'm doing (hopefully) 70 while my speedometer says i'm doing 20. searching on the internet i'm not the first to complain about this. has chevy recalled the dashboard unit in the 2004 trailblazer yet? *tr

The problems that are happening to my 2004 chevy trailblazer : i am having a whining noise in the front end of the vehicle and when i try to engage into 4wd the sound worsens and there is a vibration in the front as well the whining almost resembles a low siren sound. i am also having a major malfunction with my speedometer since the weather has gotten colder??? i could only be moving 10mph and it will register to 120 or even surpass it and then get stuck, the only way to unstick it is to shut the car off and keep restarting it until it resets itself but now it is stuck and wont reset, i went online to see if there were any recalls and i all i found out was there were tons of people having the same issues with their trailblazers as i am having. these problems are occurring at all different times during the life of the car some people have them happen around 30,000 miles or some 50 thousand and myself the speedometer is happening around 72,000 miles. the speedometer seemed to start to act up once the weather was colder. its a shame they will fix the larger suv's due to a lawsuit but since this is a smaller suv it's not covered. we have tried to replace the wheel bearings in the truck for the front end noise to only find the noise did not disappear after reading many of other complaints from others it seems this could be the transfer case on the truck. i am not going to keep replacing part after part to only find out its the drive train and something should be done about this. *tr

2004 chevy trailblazer speedometer went out. *tr

Speedometer on my 2004 chevrolet trailblazer no longer functions properly. shows the vehicle is moving at 15 - 20 mph sitting in the garage. have no idea how fast the vehicle is traveling when driving on the road. gm has recalled the full size vehicles (i.e. tahoe/escalade) that have exhibited the same failure mode in the instrument cluster. the trailblazer/envoy chassis use the same cluster as the full size vehicles, no idea why they are not included in the recall. *tr

Tl*the contact owns a 2004 chevrolet trailblazer. the contact stated that the instrument cluster malfunctioned while driving 70 mph. the contact was unable to read the battery meter, odometer, and speedometer. the contact had not taken the vehicle to a dealer regarding the instrument cluster. the contact was concerned about the related complaints regarding the malfunctioning of the instrument panel. the contact called the manufacturer regarding the instrument cluster and they advised him to contact the dealer since the vehicle was under a warranty. the vin was not available. the failure mileage was 90,000.

Instrument cluster just quit working, speedometer, fuel gauge, tach, ampmeter, temp gauge, oil pressure are all not working. all warning lights don't appear to be functioning. the odometer is not displaying the mileage. *tr

Speedometer malfunctions at various times. on carcomplaints.com there are 46 complaints of speedometer problems with this model vehicle and nothing is being done about them and nobody knows what the fix is. one garage told me the battery was bad so replacing it would fix the problem, it didn't. i had a speed control sensor put in, and that didn't fix the problem either. no warning lights are coming on, so nobody knows what else to do. i don't have any more money to put in this vehicle. the battery and the speed control sensor together have cost me over $200. *tr

I own a 2004 chevy trailblazer and the speedometer has progressively gotten to the point of being completely inoperable. the first time i noticed the speedometer read 120 mph when i was driving on the highway were the speed limit was 55 mph and i was driving with the flow of the traffic. i turned the car off and the speedometer still read 50mph. as of a month ago my fuel, oil, battery, and temp gauge are all inop; the needles never move. with this my battery, seatbelt, abs, and parking park stay illuminated. this is a safety concern because i never know how fast i'm going, how much fuel i have, if my car is running hot, i have no warning indication of anything going on with my vehicle. *tr

Speedometer malfunctions on daily basis. *tr

The speedometer in my 2004 chevrolet trailblazer ls is not working properly. the needle is pointing at 120mph while the vehicle is stopped and the needle continues clockwise past 120mph as i accelerate, therefore i am not able to accurately determine the speed at which i am traveling causing a safety hazard to myself and other persons on the roadways. this did occur as i was traveling on interstate 30 in central arkansas. i was going 70mph and the speedometer gradually dropped to 0mph then later the needle moved to 120mph. *tr

-dashboard lights, speed-gas-rpm gauges stopped working. -i can't track my speed or see my gauges at night. *tr

Speedometer will not display accurate reading, additionally headlights flicker as if i am flipping from bright to dim - causing other drivers to become angry with me - when checked with gm they said it was a problem with the electrical system of my model but there was no recall. i have seen numerous other complaints from other owners with the same problem. *tr

Instrument panel/cluster stopped working in my 2004 chevy trailblazer. at first the gas gauge and tac stopped and then would work occasionally. now they do not work at all and neither does the speedometer. over the past week my entire panel, electronics, radio readout, digital readout, temp readout all go blank and then it will come on sometimes. *tr

speedometer said i was doing 100 miles a hour tack does not work gas hand goes way pass full and when i stop and put $25 of gas in you know it is not full so not for sure if oil pressure & temp gauge is right but it is not over heating guess i will know when steam comes out from under the hood gm recall some of the cluster why not the trailblazer. *tr

The front air vents in my 2004 trailblazer quit working after i installed a new battery. my front air vents will no longer work. after researching this on the internet it appears that this is a common problem with the chevy trailblazer. it will require the purchase and installation of a new control module to regulate the air flow so the vents will work. this is a component/design problem that gm needs to fix not the consumer. *tr

Speedometer not indicating correctly on 2004 chevy trailblazer. gm will not cover replacement cost of instrument cluster even though they have recalled full size pickups and suvs for same problem. many complaints for same problem registered on various internet sites. cannot tell correct speed vehicle is traveling, and not confident in other system indicators on instrument panel. *tr

Speedometer and tachometer stopped working at 50,000 miles. *tr

Instrument panel gauges on my 2004 chevrolet trailblazer has stopped working. i have no way to gauge speed, rpm's, fuel, temperature, oil pressure. i have contacted my dealership and have been advised that my vehicle is not being recalled, nor are there any nhtsa bulletins. i have learned, however, that larger gm vehicles have been recalled for the same problem. i would like to respectfully request that trailblazers be repaired likewise. i have absolutely no funds to cover this repair. with two jobs, it is all i can do to keep above water financially. thank you very much for any advice and help you can offer. *tr

Instrument panel has rpm and speedometer displaying incorrect metrics. rpm displays zero; speedometer displays incorrect speed. chevy dealership service department says known issue for tahoe model. service representative said 2004 chevrolet trailblazer "instrument cluster" is the issue but your make and model is not on the recall list so it will cost about $500. *tr

Speedometer on my 2004 chevrolet trailblazer lt is displaying erratic readings. when the vehicle is parked the speedometer is showing the vehicle is moving at 40 mph. when driving at speeds approximately 40 mph the speedometers shows the vehicle is moving at 90 mph. multiple posts regarding this issue online. faulty instrument clusters on these vehicles. also, before the speedometer began showing erratic readings today, the speedometer didn't move smoothly. when accelerating the speedometer moved one tick at a time, similar to how the second hand on a clock moves. the next time i got in the car after this happened is when the speedometer started showing inaccurate speed ratings. this is a safety issue since you can not tell how fast the vehicle is traveling. my vehicle currently has 65,000 miles. i purchased it 2.5 years ago when it had 29,000 miles at carmax. i haven't had the vehicle repaired yet, but all posts i have read online indicate that the entire instrument panel will need to be replaced. *tr

The speedometer quit working and over the next year all the gauges have stopped working and i have been told the instrument panel needs to be replaced. i feel this is a safety issue that needs to be recalled as do alot of other people. i contacted gm and have received no help. *tr

My instrument panel abs, airbag, battery, and brake lights all came on with the temperature, fuel, batter voltage, and oil pressure gauges not working. after a few days my battery went dead. replaced the battery thinking this was causing the problem then none of gauges worked and all the panel lights were off. nothing was happening on the instrument panel. started the car the next day and had original problem. dealer checked it out and recommended a new instrument panel cluster module at about $475 installed. very big safety issue if you can't tell what's going on with your car like gas level and engine temperature. *tr

Entire instrument panel not working in my 2004 chevrolet trailblazer. first incident 10/16/2009, corrected itself within 10 mins. stopped working again 10/25/2009, no self correction this time, not working at all. calling chevy dealership tomorrow. *tr

Instrument panel (speedometers, gas gauge and water temp gauge) on my 2004 chevy trailblazer lt-a is defective but chevy will not recall and fix this problem even though they have recalled and repaired others models with this problem. *tr

2004 chevrolet trailblazer instrument cluster intermittently works. sometimes one thing works, sometimes none, sometimes all. abs light flashes on and off causing warning bell to ring intermittently. i fell that this is unsafe since the speedometer will not work. i have talked with others that have had similar problems. *tr

Oct 10,2009 58500 mile on trailblazer. driving from work pass a police running 110 mph. i was only going about 50 mph. then the tach started messing up too. still ongoing problem. can gm have a recall to fix all these complaints. they have fix other model doing the same thing. *tr

My daughter drives a 2004 chevy trailblazer. she was driving home from college the other day when the engine suddenly cut off on the highway. she still had use of the gas pedal and steering but all other functions stopped. fortunately, she was in heavy traffic, going slowly and was able to roll to a stop on the shoulder. after about 5 minutes, she was able to restart the vehicle and drove the rest of the way home without incident. since my husband and i decided that it was too dangerous for her to drive back to school, we took the car in for service. i might add that there was a recall of this vehicle in 2007 (?) that involved "corrosion in the fuel tank modular reservoir assembly." this recall item was replaced by chevrolet when we took it in for service but the technician said it probably had nothing to do with the incident on 10-9. so, after "extensive additional diagnostics" and a few test drives, chevy technicians said they could find nothing further wrong with the vehicle and were unable to duplicate the incident. additional information: we bought the car from carmax approximately 1.5 years ago. i should also mention that the same thing has happened at least two times prior to the october 9, 2009 incident, but at the time, it just seemed like a glitch. in the past few days, i have been on the internet reading about many similar incidents (among other troubling flaws with this car) with the 2004 chevy trailblazer. in some cases, the vehicles were going at high speed when they shut down. here are the links: http://www.aboutautomobile.com/complaint/2004/chevrolet/trailblazer http://www.carcomplaints.com/chevrolet/trailblazer/2004/electrical/gauges_fluctuate.shtml i am terrified that this will happen again and that the outcome will not be good. could you please tell me why has there not been a recall on this vehicle for what appears to be an extremely dangerous condition. *tr

The instrument panel doesn't work. the speedometer works when it wants to. it will read that i'm going 120 mph when i'm not, currently it's stuck all the way up! *tr

10/04/09, instrument panel of 2004 chevy trailblazer began to malfunction. speedometer and all gauges are inaccurate, cycle on and off, warning lights cycle randomly on and off continuously. unable to identify accurate vehicle speed. contacted gm dealership and gm safety/defect reporting on 10/05/09 - filed a complaint. researched that similar gm trucks/suvs have had similar defects and special coverages or recalls but not the trailblazer. other complaints to nhtsa have also been filed. i have not had the problem repaired. *tr

The speedometer stops working or will accelerates with you putting your foot on the gas pedal you have turn off the car and keep starting and turning off the car to get back to 0mph. *tr
