Driving home from vacation on the highway in a snowstorm, we realized the tachometer was no longer showing the correct rpms. It was stuck around 4000 while we were going less than that. A little while later we noticed that while we were slowing down for a red light and traveling probably 10 mph the speedometer was showing 60 mph. We quickly stopped for gas, thinking maybe those gauges were malfunctioning as well, but they weren't. when we accelerated again, the speedometer raised from 60 to eventually over 120 mph. Each time we slowed down the needle stuck, then when we accelerated it went higher. While we were driving in the snowstorm on the highway, we think we were traveling about 20 to 30 mph, but the speedometer was still over 120 mph. This was scary because under normal driving conditions we would have been able to judge our speed, but in the snow it was hard to do so. On Monday we called the dealership and were told that vehicles with under 70,000 miles they would fix but since ours had 78,000 we would have to pay for repairs. We decided we can't afford the repairs, then a few days later both gauges started working properly on their own. We are still leery of trusting them, and we are assuming they will malfunction again. I can see this problem leading to being ticketed for speeding and possibly even having an accident due to not knowing your speed.

When I bought my truck everything was fine now the gas gauge, oil gauge and RPM gauge are not working right and I see that I am not the only person with this problem, it will cost about $600 to $700 dollars to fix this and with economy the way it is I think Chevy should do something about this. My car is a 2004 Chevy trailblazer.

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.

2004 Chevy trailblazer V8 ext speedometer acting funny complete stopped shoes going 30. It reads faster than I drive so I have to figure out the stopped speed to figure out how much fast I am driving. Internet has many complaints about the same issue and similar ones like Tahoe has been recalled.

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!

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.

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.

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.

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.

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??
