2005 chevrolet trailblazer instrument (speedometer) cluster is not working. Apparently this is a common defect with the trailblazer. It simply stopped working, and now I am trying to save the money to replace the $500 cluster & in the meantime use other traffic to gauge my speed. The fuel gauge stopped working as well.

2005 chevrolet trailblazer..the speedometer has went out on my truck..it is reading 80 MPH sometimes and when I take off it goes way over 120 MPH.. This is a safety issue and I have ready several complaints on this year and model truck. I have had this truck for 5 years and I bought it when it was new and I've put several thousands of dollars into this truck this past 10 months and now its going to cost me another $500 dollars to get this fix. There should be a recall on this issue from gm. I'm going to complain to the bbb. My late husband was a gm employee and he worked for them for 15 years and was killed in an auto accident last march and gm has jacked me around since then and now I have this issue. I'm not going to buy another gm vehicle the next time. Please fix this vehicle at no charge. I'm a single parent on ssi now and cant afford this and its a safety issue on this truck. It needs to have a recall issue.

As you can see from below the complaint, seems I got a call from nikki at gm or chevy and they stated I need to bring vehicle in, pay for the diagnostic and then maybe they can decide on what to do, I believe this issue has gone on for 5 years now and they should be checking to see what the issue is...could be faulty wiring, which can lead to a fire, safety issue, could be a false warning or worse a real warning, as you can see in the link I enclosed to them, many people paying big dollars to not have this issue resolved, how long does this go on, I am hoping you guys can step in for us and hopefully light a fire and get gm and chevy to finally look into this matter..they are good about crying no sales and need the infraction from the gov to stay afloat, seems the big wigs just needed their wallets fattened, because they is no concern or worries about a safety issue, even the gauges are not working, can you please help us out, [xxx] name:[xxx] email address: [xxx] address: [xxx] day phone: ()-- ex evening phone: [xxx]ex comments: I have my check engine light on, can't seem to figure what is the problem on my 2005 trailblazer, went to this site http://www.carcomplaints.com/chevrolet/trailblazer/2005/electrical/check engine light is on.shtml and low and behold, I am not alone ...are you guys going to help us with this problem, at least tell us why this light goes on, please, it can cost thousands to fix but never have it fixed, even my battery gauge has seemed to die, and the gas gauge seems to flex on it's on also, as you can see some people are just leaving chevy behind, how about some help, you guys used to be good, what happened, I believe this needs a recall to fix this issue...[xxx] vehicle concern info: nature of concern: vehicle model: year: 2005 VIN number:[xxx] mileage: 800051 allow phone contact: yes best time for phone contact: pm.

2005 chevrolet trailblazer ext ls. The speedometer gets stuck and does not work properly. This is a safety hazard.

My 2005 chevy trailblazer is completely going crazy it seems everything electrical is going wrong with it. I am afraid to let my wife or my kids drive in it because I never know what's going to go wrong while driving. My whole gas system is gone from fuel level indicator to the gauge. My entire dashboard is not working. Lights are going out. What is crazy about this is that I am one of thousands that this is happening to. Chevy needs to fix this problem before someone does get killed. Waiting for fatalities before making chevy fixes there awfully made vehicles is unacceptable. I understand the situation our economy is in but these thousands of trailblazer owners that are having these problems shouldn't be paying thousands of dollars to be getting there entire electrical problem fixed. I do not know one owner of a 2006 trailblazer that does not have this same problem. It is unethical and chevy instead of stepping up and fixing there problem are making there loyal customers spend thousands of dollars fixing there mistake. It is truly sad that I do not trust taking my vehicle with my family in it because of being afraid my vehicle will fail to drive or malfunction. Please hold chevy accountable and make them fix our poorly mad and unsafe vehicles so we can feel safe driving our family around again.

Gas gauge and speedometer does not work on a 2005 trailblazer. I have seen many complaints on this.

I have an 05 chevrolet trailblazer ext 4.2l with 90000 miles and last march the fuel gauge quit working but not before we ran out of fuel 2 times not knowing that the gauge was giving a false reading.the occurrence happened on the freeway and once on a busy street. Very scary when you have three innocent little girls under the age of 3 that ride in the vehicle. From doing my research I see this a very common problem and a dangerous one at that because when the truck stops running you lose power steering and power breaking.

Speedometer and other instrument panel items are not functioning. Main issue is the speedometer as I have no idea how fast I am going.

Filed Oct 31, 2010 · Electrical · 79,150 miles · GA

Speedometer quit working on my 2005 chevy trailblazer as I was on the highway (I-75). At first it was reading 20 to 55 miles per hour faster than I was actually going and an hour later it quit all together. At this time it does not shoe a reading at all. Very hard to determine speed without a speedometer in heavy traffic and creates a hazard to other drivers and myself.

My speedometer stopped working around six months ago and now the oil level gauge has stopped working. From what I've been reading it is only a matter of time before the fuel gauge goes out. This is absurd that this hasn't been recalled since there are countless complaints concerning the instrument panel.

Filed Sep 28, 2010 · Airbags, Electrical · 70,000 miles · TN

Started with the service air bag message (known issue). Then the fuel gauge acted up and finally went to e and stayed. Now have and occasional surge in the fuel when I have the brake pressed (known issues). Speedometer starting acting up and no longer works (known issue). Oh and the check engine light is now always on. Started intermittently (again, known issue). Was told $500 from dealer when I called to report the service air bag message. Recall should apply to this vehicle, I don't know what the vehicle went through before I purchased it. Cloth seats/leather seats, the service air bag "sensor" is still broke! Don't have the money to fix all the "known" problems.

The speedometer stopped working one random hot day. There were no resulting injuries, incidences or crashes as a result. My trailblazer has yet to have a reliable day where my speedometer works continuously.

I have a 2005 chevrolet trailblazer ls ext and the speedometer, fuel, and battery gauges do not work properly. There is a dimming of the lights while driving and people sometimes think I am flashing my lights at them. According to http://forums.trailvoy.com/showthread.php?t=18419&highlight=gas+guage&page=2 this has been a known problem for several years and no one has done anything about it. There are several other forums out there that say the same thing,this is a major safety hazard and could cause major problems including accidents, speeding tickets, running out of gas...the problems are endless I guess. Something needs to be done. Why has there not been a recall on this with so many complaints? Are you waiting for something serious to happen?

2005 chevrolet trailblazer ext speedometer not working. At a stop it reads 50 MPH.

Filed Aug 15, 2010 · Electrical · 40,000 miles · NV

My 2005 trailblazer speedometer stops working. While driving the speedometer will read 120 MPH or more while I am only driving 70 MPH. I verify my speed through my garmin GPS. This happens for no rhyme or reason sometimes it works fine and the next minute it is broken again. This is extremely dangerous as I was traveling 250 miles on the highway and thought I was traveling at 70 MPH but I was really doing 50. The problem was that everyone including semi trucks where whizzing by my and I couldn't figure out why. This caused me to be almost run off the road as a semi almost rear ended me as he slammed his brakes on. I have not been able to fix the problem yet as gm wants 450 dollars to fix a problem that should be recalled. I have read hundreds of posts online about this exact problem on 2005 trailblazers. Apparently there is a recall on other gm vehicles with this speedometer just not on the trailblazer.

Fuel gauge failed. I ran out of gas on a very busy interstate with my granddaughter in the car. This could have been a major issue had I not been able to get off to the side of the road. It seems this is a common problem in the chevy trailblazer. I took the vehicle to the dealer and they determined it was a fuel sensor in the fuel tank. The repairs cost me almost $300.

Speedometer fails to register properly so you don't know how fast or slow you are driving; this could cause serious injury when driving on the freeway and/or up/down hills. When idling, speedometer would show from 60 to 120 MPH; reset of speedometer only lasted until next engine start.

Speedometer on my 2005 chevy trailblazer ext does not register accurate speed. It will work intermittentlyy although has been proven to not be accurate. It will stick at zero or at 120 MPH and generally goes "haywire" while in motion although it does not seem to matter if it is hot, cold, wet or dry outside and does not matter if I have my heater or air conditioner on. Sometimes it will reset itself after I shut off the vehicle but not always. I have not replaced any parts at this time due to the cost involved. ($500.00) I have received a speeding ticket due to the inaccuracy of the speedometer. (only ticket in 16 years!!!) I was unable to speak with the officer about the issue because I received the ticket in the mail and would have had to take time off work and travel 2 hours to contest the ticket. I need that extra money to pay for the repair on the vehicle to avoid any further tickets! I have owned this vehicle for 1.5 years and have minimal problems until this. I love my blazer but really need an accurate speedometer. Vehicle has 69,000 miles on it. I have put 20k+ miles on it since I have owned it.

2005 chevy trailblazer ext - speedometer has ceased to work. I either says I am going zero or 120 MPH. Have now gotten 2 speeding tickets and can not get inspected until this issue is resolved. I have been on the internet for hours now and there are hundreds and hundreds of complaints for the same thing with the same year chevy trailblazers. Next step according to most is the gas gauge ceasing to work. This really needs to be on the recall list like the other chevy vehicles with the same issue.

I own a 2005 chevy trailblazer and the speedometer and gas gauge have both stopped working. I started having problems august 2009 when I filled up the gas tank I left the gas station and it said I was on empty. I turned back around and went back to the same gas station and the manager tried to fill it up and it showed I had a full tank at the pump. It started to work again but then it would fluctuate back and forth. Now it's just not working at all for me. The other problem I have is that the speedometer went haywire. I would show I would be going 10 MPH and actually was going 50 MPH. Then when I would stop it showed while in park 70 MPH. I would have to then turn off and on my car to zero it out. The speedometer is stuck past the 140 MPH mark and has moved. This is very dangerous because I have 5 kids and this is the vehicle I use to transport us. What if I get a ticket for going to fast or to slow and what if I run out of gas on the highway. This is very scary and unsafe. I was told by a friend to see about any recalls and found none. I then contacted gm and they told me I have to take it a gm dealer for a diagnostic but there is no guarantee they would cover the cost. They said because of the mileage and year that it's from normal wear and tear I have never had a problem with any vehicle like this before. How convenient after the warranty goes out I have this problem. After looking online for recalls I found several other similar cases of the same year, make and model with less mileage having the same issues. I did ask the gm representative for somewhere else to file a complaint and they stated that they were it. I'm very unsatisfied with gm and the policies and I don't feel as if they are really concerned with these issues.

I have a 2005 chevy trailblazer and it has many problems. But the most dangerous, at this point, is the speedometer stops working. Sometimes, it won't get off of zero. Other times, it shows that I am going over 120 MPH, when in fact, I am going with flow of traffic. At other times, it shows either 15 to 20 miles above or below the speed I am actually driving. There is no common denominator as to when or if the problem starts or stops. It is very, very random. The cost to fix will be over $450.00. There are many other trailblazer owners that are having this same problem. The speedometer problem could be very, very dangerous as the driver does not know how fast, or slow, they are actually driving.

I have a 2005 trailblazer ext. The gas gauge and speedometer are both broken. I did not realize this until I ran out of gas in the middle of a busy three lane highway. My speedometer did not become clear until I found myself at a complete stop with the speedometer registering 30 MPH.

I own a 2005 chevy trailblazer in dec. 2009 I filled the car with gas and the fuel gauge immediately registered empty the fuel sensor has failed it will cost $558.00 to repair. In february the speedometer registered 120 MPH while sitting still for a stop sign now the speedometer does not work. I contacted gen motors in detroit, michigan and was asked to have diagnostic done at ed bozart chevorlet. By a representative in consumer complaints they contacted district representative for chevy and they both said that there is nothing they can do to help us. The total cost to fix our car is $1,258.00. We were told to fix the car for safety reasons and if they decided to recall the trailblazer we might be reimbursed. There are several complaints in the computer concerning the same problems with this car.
