Problems with 2004 Chevrolet TrailBlazer EXT ELECTRICAL SYSTEM

Tl*the contact owns a 2004 chevrolet trailblazer ext. while stopped at a traffic light, the contact noticed that the speedometer displayed 50 mph. the speedometer became inoperable and would often become stuck at zero. in addition, the speedometer would often display 100 mph when the contact was driving less than 50 mph. the manufacturer and dealer could not provide any assistance. the failure mileage was 66,000 and current mileage was less than 73,000.

Speedometer has completely stopped working. started out intermittent. *tr

The speedometer sticks. this problem started last summer (2008). i had noticed it happening after using the cruise control. i thought it was related to the cruise control and stopped using the cruise and it would still stick. fond out it is the instrument panel. the speedometer used to reset itself after a short period of time. now when i turn my car on it will read around 100 mph and move up past the 120 mph. it has been this way for approx 2 months. my mechanic said it needs a new instrument panel. i just researched on internet and i am not the only one with this problem. this is could result in an accident if someone does not realize their speed when the speedometer starts sticking. i have not had it replaced as i cannot afford it. i just gauge my speed by other cars or by the time it takes to go 5 or 10 miles when on the highway. not good. *tr

On our 2004 chevrolet trailblazer the only gauge that works all the time is the speedometer. most of the other gauges ' including the fuel gauge, tachometer, etc, ' don't work at all! the coolant temperature gauge works only sporadically. in addition, the dashboard warning lights also do not function properly: the airbag light, abs brakes light, and 'check engine' light unpredictably remain lit ' not always at the same time - sometimes for days at a time when the car is on. there is no pattern as to when the lights will stay on and when they will remain off. i am reporting these problems to you since i read that you are investigating this same problem in 2005 through 2007 trailblazers. i feel you should expand your research to include 2004 trailblazers. *tr

We have a 2004 chevy trailblazer, that originally began with the speedometer appearing to be stuck for a few days, would gradually decrease. followed by the rpm having the same problem. today, 11/28/08, all gauges lit up, warning bells rang, and then the entire instrument panel shut down. there was a recall for the silverado for the same year, but trailblazer owners are required to pay the repair bill for a faulty instrument panel. being unable to know your speed, how much gas you have, or if your running low on vital fluids seems to be pretty dangerous to me. the fact that gm will repair the silverado, but not the trailblazer despite the fact that they are both in the "truck" category is ridiculous. it seems to me that any one of these problems can lead to death or injury of the occupants of my vehicle, either by fire, stalling in traffic and being hit by another vehicle at a high rate of speed, or because of the inability to ensure that my vehicle is operating with the proper vital fluids, as well as maintaining a safe rate of speed. my teenage children also drive this car on occasion, and though they've been driving for 3 & 4 years, they do not have enough experience to operate this vehicle safely. there was a recall for the brake lights, how can they justify that when people are driving around without properly working instrument panels? the solution being offered is for the consumer to pay at least 500.00 to repair something vital to the safe operation of the vehicle, but gm will replace the taillight/brake light that costs pennies on the dollar. *tr

The odometer and rpm gauge stop functioning. while you are driving the odometer stops below the zero and stays stuck, it will stop at 50 and stay there, it will stop on 120 and stay there. the odometer gauge sometimes will stop below the 120 right above the digital mileage gauge. *tr

Speedometer doesn't work. *tr

2004 ext trailblazer cluster instument panel. non working rpm, speedometer, votlage meter, oil gauge, and tempature gauge. at least i know how much gas i have...i think!! *tr

I have a 2004 trailblazer with the same problems with the recall that is going on with gm. the instrument cluster is doing the same exact thing as the tahoe, avalanche, and i forgot what the other the car was. the fuel, water, and battery gauges, the airbag light, a long with the battery light stays on. went to the dealership to find out why there wasn't a recall and they couldn't give me a answer. i feel that if gm is having the same problems with the other cars and haven't look to see if there is complaints on these, why haven't they added them to the recalls. paying for the repairs and haven't to wait for gm to send out a recall on a vin type specific car is ridiculous. if they are having the same exact problem they need to check the other cars. i called the corporate office and they are telling me that i have to wait to see if there is a lot of complaints before they can do anything. if they stand by there quote of customer satisfaction then they are not satisfying the consumers and make them go through a whole ordeal, on finding a solution. now i have to wait 3 days for a part and fill my gas tank up every other day to make sure i don't run out of gas. plus, since i can't look at my instruments to tell if my car is going to overheat and make it into a bigger problem. so, since i called the corporate office we will if the people who spend money on there product will make good on customer satisfaction. *tr

Speedometer freezes and you can't tell how fast you are going. happens quite often. brought it in, but they were unable to diagnose the problem as it wasn't happening at the time. *tr

Rpm's and speedometer to not read correctly. *tr

Tachometer failed and the speedometer acted sporadic shortly thereafter. i never have an accurate speedometer reading on my 2004 trailblazer that only has 50,000 miles. i am in the process of finding a repair shop or getting my dealer to fix the problem at a discounted rate or free. *tr

2004 trailblazer - all gauges don't work or max. out; speed gauge and gas gauge quit working. started at about 55,000 miles. *tr

The speedometer on my 2004 chevy trailblazer is not working correctly. while the vehicle is stopped it still registers 15 - 20 mph. i have read reports of this problem all over the internet but gm is not issuing a recall or service bulletin that anyone will admit to. overall this truck has served my family well, but this is my wife's truck (our main vehicle) and i need everything to work properly. we purchased this vehicle because she travels with our children and we need a very dependable vehicle. if this was an isolated problem i could understand the repair at my expense, but report of this problem are all over the internet. gm should stand behind their product.*cn

Speedometer is incorrect. it will start off fine but after driving for about 10 min the speedometer needle will start falling to 0 at a slow pace. *tr

All gauges fluctuate constantly or stop working at times. you never know how fast you are going or if the car has appropriate fluids. this is a very dangerous situation and i have found via the internet there have been numerous complaints about this issue. there is definitely some type of electrical problem with this vehicle. *tr

The speedometer on both my 2004 chevy trailblazer ext and my 2005 chevy cavalier sedan have been functioning erratically, i.e. registering 100 mph in park and then not registering a speed at all. *tr

Gauges in gauge cluster give false readings speedo in particular reads 120mph when not moving , when vehicle switch off and then back on the reading changes , sometimes goes back to normal happens periodically through out the week; gauges affected tach, speedo, voltage. *tr

I own a 2004 chevrolet trailblazer ext. in nov 2007, the speedometer and tachometer started acting erratically. the tachometer would seem to stick and the speedometer would register either grossly over or under my current speed. it sticks when trying to accelerate after a deceleration. i have been able to get it to reset only after turning the engine on or off several times consecutively. i have been going down the interstate at speeds of 70+ (within legal speed) and the speedometer will show -5 mph. also, i have been going approx. 60mph and the speedometer shows 90+mph. i took it to the dealership where i purchased it in nov 2007 and at the time, their instruments couldn't detect a problem mileage at time of failure approx. 104,000 (had a 100,000 warranty). they charged a $100 diagnostic fee to tell me they didn't see a problem. current mileage is approx. 134,000. i have not had the problem fixed. *tr

2004 chevrolet trailblazer ext speedometer does indicate correct speed. operation is intermittent. with cruise control on, indication is from 0 mph to pegged out, with needle fluctuating. no accidents, injuries, or speeding tickets, yet!!! *tr

Tl*the contact owns a 2004 chevrolet trailblazer ext. during the winter, the speedometer malfunctions. the dial will show 100 mph when the vehicle is traveling 50 mph. the dealer stated that a new speedometer was needed at the cost of $500. the dealer information was unavailable. the current mileage was 83,216 and failure mileage was 47,000.

Speedodmeter sometimes work sometimes not working or not working at all. *tr

Speedometer stuck and is pointing straight down. at first it was stuck at 80mph and then just fell all the way to the bottom. now it does not work at all. my 2004 trailblazer only has 50k miles. *tr

Make: chevrolet model: trailblazer 04' ext the speedometer on the vehicle has stopped working. this seems to be a huge problem with "trailblazers" between 03-04. many complaints, but no action taken by chevy to fix this. i would like for this to be looked into, as this is a huge safety issue. people driving around and not knowing their speed could cause an accident?? *tr

The speedometer on my 2004 trailblazer works intermittently. this began in the fall of 2007. sometimes it works seemingly fine. it will then freeze on a speed. sometimes it will register a speed that is obviously incorrect. for example it will register a variable speed that is 20 or more mph faster than we are traveling. it sometimes points straight down. then last week "out of the blue" it worked again for a few days. unfortunately, this only lasted a few days. i never know how fast i am going and try to stay in the flow of traffic. i asked the dealer about this and they did not mention any other problems with this and told me it would cost $500 to repair. this is a real safety issue. *tr

Speedometer started to act erratic at about 40k miles. now at 72k miles, does not work at all. i just spent $200 trying to repair, only to find out after that failed, that this is a common problem with gm. how can they justify recalling the tahoes, avalanches, etc, for the same problem, but leaving the trailblazers out of this safety recall? *tr

I purchased my 04 trailblazer in may of 07. up until july there where no problems. since then my speedometer and gas gauges have been acting up. on many occasions they give the wrong readings. i have been stopped twice for speeding when i did not think i was because of the wrong reading. last week on 5 sep 07 the speedometer completely froze giving me no reading at all. since then the needle has started moving but is no where near the correct reading. *tr

The speedometer on my 2004 chevy trailblazer is not working properly. i never know what speed i am going. it reads 120 mph when i am at a red light! i'm constantly in fear of being pulled over by police whether i'm in the city or out in the country because i don't know if i'm following the speed limit. i took it to the dealership and they told me the whole dashboard needs to be replaced. the price of the part is @ $280 plus labor. some of the interior lights have burnt out and labeling of knobs have faded. the hub caps on the 17" wheels aren't secure enough. they come off easy when driving through water. i lost them during a storm and had to replace them when i saw they were missing. of these, what worries me the most is the speedometer as it is important for safe driving. *tr

I have a 2004 trailblazer ext and a 2004 crew cab silverado. both of my speedometer are sticking on both vehicles. i have not taking to the dealership but from my research on the web it looks like it is going to cost me a lot of money. *jb

The speedometer went to 120 and stayed for a couple of days and then slowly came back down but when traveling 5 mph it will say 40 to 90 depends how it feels. gm will not back up under warrant. vehicle is out of warranty but seems to be a common problem with chevrolet trucks...vehicle is a 2004 trailblazer ,with 40,000 mi.. *jb

At 40,000 miles my chevy trailblazer's speedometer stopped working- at 120 mph and has been stuck there for a week. *jb

Instrument cluster my 2004 chevy trailblazer has been acting erratic or not at all on some of the gauges. i've read that it is a very common problem and some have been recalled but not all. *tr

At approximately 36,000 miles the speedometer on my chevy trailblazer started acting funny. at approximately 40,000 miles it started to get stuck. at 45,000 miles it stopped working altogether. it is now stuck in the down position pointing toward the instrument panel. i have spoken to numerous chevy trailblazer owners and have visited a number of online discussion groups and have found out that a number of people have had this same problem. this is a very serious safety issue, which can lead to injury or death. *nm

This is the second complaint i am submitting about the speedometer on my chevy trailblazer. i just wanted to include some links to customer discussion forums, in which you can see that this speedometer is a big problem. gm tries to ignore the problem and most customers have no outlet to vent their problems, outside of the dealership who is trying to hide the problem. please take a look at some of these discussions and you will see how gm is ignoring this very serious problem. http://www.topix.net/forum/autos/chevrolet-avalanche/tji11lgm9554merna http://townhall-talk.edmunds.com/direct/view/.f0fb75b. *nm

One day i was driving down the road at about 40 mph, but when i looked at the speedometer it was reading 90. for about a month the speedometer never reached zero and performed normally. one day it finally did reach zero and acted properly for about a week, then began acting up again. since then, it has gotten stuck pointed down and does not move at all. also, my rpm began acting up as well. now it starts below zero and only moves occasionally. this is a major concern for me because i can handle not knowing the exact speed of my vehicle, but not knowing the rpm also makes it difficult because i have no real way to determine my speed. this is a dangerous issue that must be addressed. i have a friend with a trailblazer like mine and he has a similar problem. speedometer doesn't work. online i've also found hundreds of people who have this same problem. gm must correct this electrical glitch! *tr

2004 chevy trailblazer. intermittent engine stalling since new. many service visits to chevy dealers to fix, however mechanics stumped. local gas station mechanic found the problem having to do with components in the emission control / vapor recovery system. now chevy needs to figure out the cure. in the meantime i get to drive around with the "check engine" light on. i guess this is better than being crashed because my car stalled in an intersection or on the highway. chevy mechanics and engineers need to get the "duh" award. very bad customer service and diagnostics performed by chevy. i would still like to have the check engine light to go off, and have the engine not stall if that is possible. please send info to have this done if possible. *jb

Engine stalls at various times for no reason. have had it into dealership many times. dealership has been unable to isolate problem. service engine soon light came on after first stall. dealership reset computer. since then, the engine has stalled at least 5 times. ses light has not come back on. engine usually restarts after approx 5 minutes. *nm

When had the crash which was very hard loud and scary the air bags didn't deploy nor did the air bags on the side of seat. the crash was very serious and the electrical system and powertrain to windows. *tr

In march 2006 at approx, 38k miles our speedometer and tachometer started going crazy and they still do not work. now the water and oil gauges are going out. *tr

Speedometer, tachometer and oil pressure gauge all stopped working on 2004 chevy trailblazer. *tr

Full destruction because of fire i was on the way back from a long trip in southern chile (up to ushuaia) over the "carretera austral" and, after about 9'000 km drive without any problem, i saw a white smoke back my vehicle. oil pressure: normal, motor temperature: normal. this meant immediate stop along the "ruta 40 norte" in argentina (about 100 km north of bariloche, on the way to neuqu). while stopping, i felt the brake pedal just going without immediate reaction but the pression came back. while bringing the gear shift to position parking, i did not feel any sensation, as if it would have no connection; the automatic door blocker connected to the gear shift did not work too, so that we had to unlock the doors manually. after having disconnected the engine, i saw white smoke coming out from the upper left corner of the motor. i opened the capot and the smoke came from the left corner (close to the driver's place). suddenly, some material in flames fell to the bottom, about middle light left of the car. i tried to put out the flames with the extinguisher, but other burning material fell. other people had stopped and helped me. we pushed the car a little ahead - though the hand brake was tied and the gear shift on "p", but burning material fell again. in the meantime, my wife and children throw out the luggage, so that we could save almost all of it. but the car burned entirely. what could be the reason of this incident ? thanks god, i stopped immediately so that nobody was injured nor burned and no third party suffered any damage. *nm

There has not been an accident yet, just one looking for a place to happen. my vehicle i believe has an electrical problem. which in turn affect all functions of the vehicle, safety being one. i have had (2) fan switches go bad (2) crankshaft sensors go bad. (1) cruise control malfunction. (1) turn signal relay (1) radio console replaced for overheating (1) headlights when below 32 degrees flucuate in brightness till vehicle warms up. dealer stated this is normal operation. ha,ha, and transmission shifting problems (1)they reprogramed computer to solve, next some solinoid replaced and now the problem is back. i have a family of 6 that i have in the vehicle 90 % of time. i now have concerns that the wiring must have a short somewhere. which potentially could cause a fire, or an accident due to what happens when the headlights go out or antilock brake system fails or taillights, etc. gm refuses to replace wiring in vehicle. gm rep told me to contact whoever i wanted to. they are not going to stand behind fixing the problem. just keep replacing the electrical items as they go bad. *nm

We are the owner of a 2004 chevy trailblazer. i would like to file 4 major concerns regarding our vehicle. the first i have brought to the attention of the chevy company. our trailblazer was shutting off due to a bad seal somehow connected when the heat/air is running. the vehicle just shuts off and you lose complete control. we had an outside mechanic fix the problem. the second is the loss of our windshield front windshield wipers. they no longer work. the 3rd is the rear molding broke loose from water collecting and then freezing with no way of preventing this from happening. we lost this piece of molding while driving on the highway and it hit a semi truck. the 4th is a major electrical problem that has not be able to be diagnosed. each morning when starting the vehicle, the suv will act like the battery is dead and then start. i have had this vehicle in while under warranty and problem was not found. i am quite concerned with this vehicle. i am not sure if others have had these problems, but i would like to have them notated. we are currently on our 3rd battery since 2004. *tr

Transmission shifts hard from 1st to 2nd, sometimes when at a stop it stalls before taking off, sometimes rpm bottoms out. 4 wheel drive only used about 3 or 4 times, each time it stalled before going into 4 wheel then would not come out of 4 wheel for about 2 or 3 minutes. *jb

I am complaining about a 2004 chevy trailblazer problem the speedometer is measuring incorrect speed or not working at all. i can be parked and it reads 60 mph i am driving it reads 120 mph. in speaking with several gm owners this is a problem with quite a few gm vehicles and is very dangerous. i think this should be looked into before someone gets hurt. it is very scary not to know what speed you are driving at. in speaking to several owners and looking at web sites of complaints this is a problem and has been one for a long time. i do not blame my dealer i blame chevrolet or gm whoever made the car there are so many complaints about this speedometer with other makes from gm, its not the dealers fault for this problem. *nm
