This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Instrument cluster failure starting with tachometer then speedometer. At 90,000 +/- miles always have intermittent / obviously wrong info from tachometer (usually past 7000) and speedometer (always reads <20 mph).
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.
The speedometer in my 2004 Chevy Trailblazer ext completely stopped working about 6 months about. We have been dealing with this issue and just praying we do not get a speeding ticket. Now the check engine light continues to stay on even when reset. I am not being told I need to check the fuse which was unsuccessful. I can only imagine if the next thing to go will be all the electronics in the dashboard. This seriously needs to be a recall item!
The speedometer on my 2004 Chevy Trailblazer ext operates incorrectly. The speed indicator sticks, goes over 120 miles an hour and stays there, and sometimes does not move at all. This is an everyday problem.
Instrument cluster panel issue with tachometer actually exceeding 7000rpm while vehicle is idling. I did a quick search online and found that there have been many complaints about the cluster panel malfunctioning. It was recommended that I file via NHTSA to see what may be able to be done or if there was already a formal recall on this particular defect. I have tried removing the cluster panel fuse from the fuse box then starting vehicle then turning vehicle off and replacing the fuse to recalibrate it. My understanding from the research is that the stepper motors used in the panel are faulty.
My speedometer has stopped working on my 2004 Chevy trailblazer. Half the time it sits on 0 the other half it goes 120mph. I never have a clue how fast I am going.
2004 Chevy trailblazer speedometer and gauges started working erratically around summer 2009. Speedo and gauges stick or peg out daily. GM does not recognize this as their problem yet there are hundreds, maybe thousands, of blogs on the internet of this same problem.
My 2004 Chevrolet Trailblazer ext has the same problems all the other trailblazers have. Poor design and subpar manufacturing of parts in foreign countries have resulted in electrical problems that cannot be fixed.gauges and lights randomly going crazy, heat and A/C may or may not operate, vehicle may or may not start, key may or may not release from ignition. Ignition switch has been replaced multiple times in last two years and often brand new ignitions straight out of the box from the dealer parts department are no good. As other GM vehicles with the same exact problems have been recalled one would think trailblazer owners should deserve the same courtesy.clearly GM disagrees. I guess when you know uncle sam will always be there to bail you out you can do what you want and still sleep good at night. I wouldnt know. As the parent of four children this is a serious safety issue with me. I can no longer drive it as I know it is not dependable.
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.
We currently own three Chevrolet trailblazers - 2004, 2005, 2006. On each on the three trailblazers, the dashboard instruments have failed, including the speedometer, oil pressure gage, fuel gage, and engine RPM instrument. The driver no longer has the ability to verify how fast the vehicle is traveling, or potential problems with the engine, or the remaining fuel in the gas tank. In taking the vehicles to the dealer, they insist that it will be a significant repair requiring diagnosis and removal of the entire dashboard cluster and estimate the costs to be well over $1500 for the repair. Since the same problem has occurred on all three of our currently owned trailblazers, this suggests a manufacturers defect with the entire dashboard cluster.
My check engine light started coming on and staying on; then my oil gauge started going wacky, from one end to the other; next, my gas gauge wasn't reading correctly and I had to keep putting gas in the car just to make sure I didn't run out because you couldn't trust the gauge. The gauges often correct themselves out of the blue and then they start messing up again with no warning. Today, my speedometer read 0 while I was driving about 40 mph. It stayed at 0 until I stopped at a traffic light. When I took off, it went up to about 45 when I was only going about 25-30. I have no idea how fast I am really going, which is scary and dangerous. I am also very frazzled by all the gauges reading different every day when I am driving 40 miles back and forth to work wondering if and when my car is going to break down on the highway or in heavy traffic.
My 2004 Chevy trailblazer has multiple lights on -brakes, airbag, battery, service engine soon. All the gauges on the right-oil, gas, battery are below the red line as if the car is off. The car locked itself with the keys in it while it was turned off-had to call emergency road service to unlock. The mechanic states all the lights that are on are actually functioning and that the dashboard cluster module is causing the problem. This is a major safety issue and it appears multiple people have had the same type problem with trailblazers-why hasn't there been a recall re: This issue?
Check engine light - for over one year now, and 4 various mechanics, no once can figure out why my check engine light comes on. I have replaced two air sensors (actually 3 - one was bad)... I have spent close to $1,000 to get this fixed - but the dam light continues to go on (intermittently) sometimes it's on for a month - off a day - on two weeks - there is no pattern. The last time the light came on, my car began stalling in traffic and stop signs. Last mechanic spent 5 hours tracing all the codes back - nothing. Next day had another mechanic check codes and the engine running cool as well as a few others showed up. If no one can figure this out - where is the recourse. I feel like I am being scammed over and over. I stalled on rt. 24 slowing down in traffic - and was almost hit by a box truck because I just sat there. Who can help direct me to a repair which will ultimately end this issue? now, the lights off this week (watch, now that I say this it will come back on). The only thing I notice is that many times the light turned off after I filled the tank. So, is there anyone out there who knows what's wrong (referring to mechanics who take us for a ride $$$)? I challenge anyone out there to figure this out.
My Chevy trailblazer displayed a service engine light and 4 wheel drive service light a few days ago. Got it to the dealer. They stated the thermostat and 4 wheel drive switch needed replaced. ($550). The day this was replaced, I drove it home and tested the 4 wheel drive switch. As soon as I pressed on the gas in 4 wheel drive, the tach shot to 5000. It displayed 5000 for the rest of the day (even while idling). The next day, the tach stopped working all together. Dealer won't take responsibility for any error or reasoning to why it quit working. Just a coincidence"???"
There have not been any accidents or injuries yet, that I know of. There have, however, been many complaints that I have seen for the same problem I am having and Chevy does not care. The speedometer and other gauges on my 2004 trailblazer do not work correctly, the speedometer can read 0-120 when at a complete stop. Therefore we never know how fast we are going and with children in the vehicle this is very disturbing. Besides the gauges the wires for the headlights keep burning. I was told when I had the first one fixed that it is very common in these vehicles. The fact that both of these problems are so common with many Chevy vehicles and they are recalling some and not all, I guess I just want to know why not all?
The speedometer and battery guage will not work. The speedometer shows over 100 mph when you are not moving. Called the dealership and they said they get calls everyday on this problem, but GM does not have a recall on the trailblazer only on the pickup trucks.
