My speedometer sometimes goes to 0 & I am moving down the road. Sometimes it says 30 & I am sitting still, and 55 & I am going 75. What are we going to have to do to get a recall on these trailblazers. I have read so many complaints about the same thing that it makes me sick just to know Chevrolet won't do anything. If they are honest people & they want to go to heaven, they better do what is right or face God & yes there is a God. They will find out on judgment day & it won't be long. I hope they read all these complaints.

i to have had this problem occer today. and after seeing the long list of complaints and the fact that other years and models have had this problem and were recalled im boiling mad. also had the fuel sensor problem that i paid to have fixed.

i have been a gm person for 33 years. i do love my trailblazer but after the problems i have had with this thing and the way i got treated at the dealer, after the warrenty ran out, i am boycotting gm all together now. time to go foreign. (and they wonder why we buy foreign). its time gm stand to the plate and fix these issues if not hope to see and cant wait to see them go under. gm was bailed out with our tax dollars then treat loyal customers in this way is utterly acceptable. i to am fileing a complaint with the nts but people i really dont see anything comeing of it for the simple fact that if your speedometer is broke it is our responsibility when the speeding tickets come. and thats revenue for the ailing states. so dont hold your breath on these complaints going any where, do your selfs a favor and start buying foriegn. good bye gm and at this rate the american car makers all together

Never would have thought I would be having a problem like me spedometer not working or that anyone else would be. Very disappointing especially when you are on the freeway. Just happened again yesterday for the second time and after reading all the complaints, looks like it is something that will not go away. And by the sounds of it, will cost a good amount which I will have to think about. Only 65,000 miles on it maybe I could get a good trade in. Won't be at a Chevy dealer.

How many complaints is it going to take before Chevrolet takes ownership and pays for someones death?

This Trailblazer continues to disappoint us. We bought it used in 2009 with very low mileage for a great price. Now I see why the previous owner was so anxious to be rid of it. We’ve had three fairly significant problems in less than two years. First, the remote keyless entry went out. Then the latch on the back door broke. Those two problems cost $600 to fix. Now, at a mere 68,000 miles, the speedometer went out. The dealership quoted $550 to fix it – crazy! I will never buy a Chevy again, and I will never give a crooked GM dealership a penny of my money. We are now officially a Ford family!

Speedo malfunction like many others seem to have. I am not usually one to rant but this is pissing me off. I cant pin it on the hot or cold weather like others seem to be able to. Here in Seattle during this fall/winter we have had some weird swings of quite warm cold outside and it happens on either type of day whenever it feels like it. Last time we were driving a friend back from the airport at midnight and I was about to politely ask my wife to speed up so we could get home cuz the speedo said she was going 45 on the freeway (which might not have been unusual) but she was beginning to fly past cars as she sped up. Then the speedo kept reading slower as we went faster. It comes and goes. Works correctly when it works which seems to be about half the time. I will register my other complaints in the appropriate areas but will say here that I also have about every other one I have read about on this same rig. Gas gauge, whining pulley, check engine, DTC's wont clear etc. LEMON and even when it was under warranty they wouldn't fix any of it. I should have known from the blazer I had before this one which had similar problems but I wanted to believe in Chevy and Buy American (no cap A on purpose, SAD)

Well the speedometer is the fourth big thing to go wrong with this car since I bought it two years ago. First was the fuel tank sensor luckily I had the 12 months warranty from buying it used. Then it was the electrical unit on the driver seat also under warranty. Then I heard a knocking sound and the Chevy dealership said they couldn't find it, but once the warranty ran out it got worse so I took it back and they found the problem and it was the bolts on the exhaust manifold were broken off. They tried to make me pay 1700 dollars to get it fix and had no record of me bringing it in for the knocking sound before!! Thank god my wife is good at confrontations and she managed to yell her way into them paying for it. Now i have a speedometer not working, I think I bought a lemon!!!! They told me 400 bucks to replace it and I told them to stick it up there asses!!! Don't buy Chevy or maybe the dealership that I go to isn't worth a damn!!

I purchased my 2005 Chevrolet Trailblazer in 2008 at 44,000 miles. I thought that I was getting a really good SUV. I had no clue that I was getting into a bad one that would have all the problems that I was experiencing. I thought chevy made good cars. I guess I was wrong.

Well about a few months ago I noticed that the speedometer was reading something different then what I was doing, It even had the nerve to spin all the way around. I did not know what was going on. I then noticed that shortly after that I filled up my truck and the gas hand just went to EMPTY!!!! I thought that I had put some bad gas in the truck HA HA SO I called the dealership and explained to them what was going on and the told me that I was looking at 1200 to get the truck fixed. I did end up running out of gas and replacing the fuel pump which is very expensive. I still have to make car payments and I am just sooooooo unhappy with the TRUCK THAT I ALWAYS WANTED. UGGGGGH!!!! I am looking to trade in or just send it BACK!!!!!!!!!! Tired of spending all the money in repairs in a ROUGH ECONOMY!!!!

I, like many other '05 Trailblazer owners, am having a problem with the speedometer cluster. It is always misreading my speed. I never know when it is going to act up. Last week it happened on the freeway. It read that I was driving 95 mph but I had no idea how fast I was really going. Sometimes the needle drops below the 0 and doesn't work at all.

I have contacted my Chevy dealership and GM directly about the problem and was told that I need to pay to have it fixed because it is a major safety hazard....DUH! I would get it fixed but I don't have $500 laying around to do so right now. Plus, I think it should be the responsibility of GM to insure the safety and integrity of their product. A recall has been issued for the 2003 and 2004 Trailblazers so they obviously are aware of the problem. Now I am worried that my fuel gauge will start misreading since this seems to also be a trend.

I just entered a complaint on the government's traffic safety website. Here is the link if you would like to voice your concerns as well.

Hopefully GM will do something about this if enough of us complain!
