Chevrolet TrailBlazer Speedometer



  • I have been having the same problem not only in our TB, but also in a Silverado we own for our small business. We spent $400, 6months ago to have the sending unit in our gas tank replaced, and $800 to have the dash cluster replaced because the speedometer and oil gage were no longer working. I am at the point were I refuse to spend the same money on the truck that we just spent on the Trailblazer.

    I contacted CHEVY, and asked why they were not assisting their customers with these repairs, clearly there are a lot of us:

    Who do they think they are? I consider this a huge safety issue.
    As a tax payer I have spent more than enough money on GM, when it comes time to buy our next 2 company trucks, I think we will go with FORD. And my next personal vehical will be a company who stands behind what they make, and belive in customer service.
  • I too have problems with my speedometer on my Trailblazer. I have actually seen when mine goes bad. It kinda "sticks" while driving and then gets all messed up. Mine usually reads that I am going faster than what I actually am. Only once has it read slower than my speed. I CANNOT believe that GM is not going to recall this problem. I guess they just want to be sued instead. This is a major safety issue. I have two small children and cannot rely on my speedometer to know how fast I am going. Does GM expect us to just guess? I also do not have the kind of money at this time to fix this problem, as I have seen on many website that this is quite expensive. I feel I shouldn't have to pay for this anyway since it should be recalled due to the high number of the same type of problem. What is the explanation behind them recalling Tahoe but not Trailblazer on the same issue??
  • My husband and I have a 2005 Trailblazer EXT. The fuel gauge has not worked for months now and all of a sudden over the past few weeks the speedometer started sticking as well. We have 4 children. 2 of them live with their Mom part of the time in KY (we live in SC). So we have to meet in the middle to pick them up severl times a month. We have to drive through the NC/TN mountains, winding mountain roads, with 4 small children in the back not knowing what our speed is. You go too fast you can flip, you go to slow and the big rig trucks are barreling down on you because it is hard for them to slow down too much when going down the mountain sides. This is a very serious very dangerous issue.

    In order for me to look up recall information I will need a VIN. Some recalls are VIN specific. Service bulletins are for the service staff only. I am a customer service representative and I am not able to access those. I would recommend speaking with the service department, but I doubt that they will provide you with the bulletin. They would be able to fix the vehicle for you. If you would like please feel free to email me directly.

  • Ours just went out yesterday on our 2005 Trailblazer with a bit over 53,000 miles. I wonder if anyone has filed a class action suit against them about it?

    Because unfortunately when you're dealing with companies who put $$ before their product quality and customer service, a suit is the only option to get them to listen.

    It's obvious that it's a problem, and one that shouldn't occur at any mileage let alone the mileages it's showing up on. This is the first car I have ever had a speedometer stop working in, I think it's pathetic.
  • I have a 2004 EXT purchased used w/15000 miles on it, it's now at 78,000 miles. I have truly enjoyed my Trailblazer but I share this same issue with (as in all previous post) many others. I intend to make my call to lodge my complaint today.

    I never expected to purchase a vehicle "problem free", but I'am very concerned about the number of these specific issues as a whole, to imagine the MASS number of these "daily drivers" out on our roads everyday is just case for concern. Even more so that the vehicles with the "RECALL" are out numbered by a wide margin by those of us driving the Trailblazers. Seems to me someone at GM thought these actions out fairly carefully for their outward apperances of doing "the right thing", but only if you have spent "so much money" with our company, right?

    So as I said I will call and make my complaint and hope ALL of you will do the same. Maybe if we ever reach that "unknown" number of complaint makers we can all get our problems fixed.

    I am having the same problem, my speedometer will get stuck at 75mph, then once i slow down, i just bottoms out and stays, and when it feels like it, it will works its way back to zero, counter clockwise. Its frustrating to not know how fast or slow your going, and yes i have heard it can be very expensive. It would be nice if GM will fix this problem.
  • i think i found a suggestion to all of this, i read on about a guy who takes big companies to small claims court to sue them for anything that had affected him negatively, from banks, to computer companies, to travel sites. he has a 80% success rate. if all of us sue gm in small claims court, maybe they'll finally do something about these crappy instrument clusters

    I read some of these posts and followed the advice to call Chevrolet and I got nowhere. They told me that they could not assist me with the cost b/c my mileage is too high. Its 138k and a 2003. If anyone knows of any other help, that would be great. The dealership is quoting aroung $600 to fix this problem. :cry:

    2004 Trailblazer LT 48,000 miles, same problem. At start up all gauges not working, seat belt light, battery light, ABS light all lit. They will all start working after driving a distance that is variable. Still diagnosing! I did replace the stepper motor on the speedometer last year!
  • We just bought our 2004 Trailblazer LS w/ 110,xxx miles on it and noticed the speedometer doing the same thing. We just bought it last night and it started sticking this evening. We also have 2 children, one only 2 children, one born just two weeks ago. This makes me very nervous to drive it. There has to be an easy, inexpensive fix. We certainly cannot afford to pay $600 to have the darn speedometer fixed at a dealership. Please help!

    I've got a 04 trailblazer and I'm experiencing the same problem everyone else has. Speedometer and tachometer were sticking for a while. Then it failed at about 112,000 mi. This is in addition to the cheap plastic bolts they have to attach the upper third brake light panel. I live in Wisconsin and my Trailblazer doesn't sit in a garage during the winter. So snow got stuck underneath the piece from opening and shutting the trunk. It snapped off while I was driving and luckily nobody was behind me. As for the speedometer, I'm expecting a child in July and this is ridiculous that I even have to consider buying a different vehicle because my wife doesn't trust this one. It's just dissappointing GM sits there and does nothing.

    I have a 2004 TrailBlazer LT - 1 year, 3 months ago - I replaced the instrument cluster at the local dealership. This past weekend, I went to start the car and it was dead. I could not even get the key out - I had to get a ride to buy a battery charger - I got the battery charged and the key came out. I bought a battery 1 year, 5 months ago. So I backed the car up to take it to get the battery and that checked and the spedometer was pointing south. The needle does not move but you year it. So I called the dealer where I bought the car and had them install the new instrument cluster and they said the speodemter was only covered for 1,200 miles or 1 year. So all they will do is look at it. My question is why did the car go dead and what could that have done to the speodmeter. I'm so ticked right now.

    Yeah, my wife's 05 Trail Blazer speedo is out of wack. What gets me that we need to take it to the Chevy dealer to look at it to tell us that it is broke and pay for that then schedule to get it fixed and pay more on top of that. Really? A whole lot of people are having problems and GM does not consider this a "safety" issue? I guess a bunch of people may have to die before GM considers this a big issue.
  • mrose15mrose15 Posts: 2
    So I guess my question is, is there not some kind of class act law suit that can be filed? B/c surely this can't be right I refuse to have an accident or something more severe due to the fact that GM doesn't care. I truly had no idea so many others were experiencing the samething.

    I apologize for the problems you are experiencing with your vehicle. Have you taken the vehicle to the dealership to be diagnosed? Could you please email me your VIN? I would like to look further into your situation.

    You used the magic word to get a response. Lawsuit. Unfortunately that seems to the only attitude that gathers a response.

    GM is not concerned about this safety issue. UNTIL SOMEONE IS CRITICALLY INJURRED, or worse, nothing will get done. Eventually the TB will become old and people will move on to other vehicles. That is what GM is hoping for.

    I finally had to send mine off to get fixed. Look on eBay and you will find a guy that does nothing but fix this problem. A look at the number of these he has fixed should be an indicator that this is a wide spread problem.

    If sales decline, the corporate wallets will cry to DC that they are not making as much as they used to and we will continue to fill their coffers with our taxes.

    I am having the same issues with my 2005 Trailblazer xt my vin number is 1GNET16S456148949, speedometer and gas guage going crazy, i move 120 mph sitting still.

    Can you please tell me what we need to do, apparently my car is falling apart we are also having the blower motor control issues that when I searched was a problem too on these vehicles. we are in the process of trying to fix it now.. we don't even have 100,000 miles on it yet, I think barely over 90,000 if that...

    I would like to set up a case with GM Customer Assistance. In order to start the process I will need your complete contact information (including full name, mailing address and phone number) and involved dealership sent to me in an email. Also, could you please provide a brief description of the problems you are experiencing?

    Thank you,

    My wife just had the same experience yesterday on her 2004 TB EXT as well. Is GM recalling?
  • ljksmomljksmom Posts: 3
    I just sent you all my information via email.
  • This is my first post. My 2005 Trailblazer has had a speedometer and gas gauge problem since just after I purchased it last year private party with only 70k mi.. . I wish I would have read up on the trailblazers before I bought mine... it's left me stranded (thankful it was on my way to pick up the kids) and we are total CHEVY family (this is our 5th). I'm not sure if I would buy another Chevy after owning this clunker.. honestly. What are folks doing about the non working speedometer and gas gauge issue? Thanks for any info you can offer.
  • Caron,

    I am new to this site and unsure how to send you an email.

    A waste of our time, yes they contacted me, but wanted to set up a diagnoses at my expense and repair at my expense, ashamed that they don't step up to the plate and take responsibilty for faulty equipment.. So don't get your hopes up when they start sending you emails that it is being reported and checked into, just a way to get more money out of us at the dealerships.. I have a friend who is a GM mechanic and when I first had problems and asked him what he could be he knew immediatley and the cost of around 500.00 to have it replaced at the dealership.. Good Luck I hope you have better luck than I did... I will just keep calculating my fuel supply on paper and an estimate of how many miles I have driven, and hope I don't get a ticket for speeding one day until I can afford to get it fixed......
