We were doing our normal fill-up (truck was off) and after we filled it up & turned it over, the fuel gauge shot way over the 'full' mark. Every time we turned the vehicle on, the fuel gauge was reading differently, I have no idea how many times it was right. The oil pressure and battery charge gauge have also been giving false/sporadic readings as well. After much searching, I found the root cause of this to be a very common problem not only in the trailblazers but the tahoes and several other of their vehicles (the instrument clusters are faulty). Given the expansive nature of this issue, and the potential dangers of not knowing your speed, fuel level, oil pressure or rpms, I'm having problems seeing why this isn't a recall already. It seems to happen more in the 2003-2006 models more than others from what I've found as well.

The speedometer started to malfunction while driving 40 MPH north bound on davis blvd. The speedometer was reading 80 MPH then when stopped it was still reading 80 MPH. It then moved past the gauge not allowing to know my actual speed. This to me is a car safety issue because we never know how fast we are going. The gas gauge has been malfunctioning for more that 24 months. The caution light (yellow) turns on when you need to fill the tank so we have been using this light to fill the car with gas. The gauge needs to be repaired. Since the car is not abused we fill this is something which should have lasted the regular 100,000 miles before there was a problem. The warranty period is over. From talking to other users and repeated searches online it seem to be a regular failure item. I believe it should be repaired by general motors corporation. Many drivers have had to spend lots of money to have this item fixed in less than average mean times between failure of (100,000 miles).

The electrical system on my 2004 trailblazer ext is not operating properly. The tachometer doesn't register, nor does the battery gauge and uncertain if the reading on the oil gauge is accurate. The fuel gauge is not operable, the needle is either pass e(empty) or pass f (full), I'm constantly re-fueling for fear of running out of gas. When first starting the engine, the speed indicator might register correctly, but then it falls below 0 MPH while traveling speeds of 35 to 55 MPH and other times it may indicate speeds in excess of 100 MPH. Problems with the speedometer first started in june 2012 , I used a GPS to keep track of traveling speed. Afterwards, the other gauges started to malfunction. No parts have been repaired or replaced.very concerned about safety issues, as I occasionally transport my grandchildren to appointments. Has chevrolet made any amendments to correct these problems? Assistance needed please.

Fuel gauge stays on empty and oil temperature gauge stays at 260 degrees. The speedometer sticks and resets incorrectly at random intervals.

The RPM gauge, battery gauge and the fuel gauge stopped working. First the RPM gauge stopped and then about a year later the battery gauge stopped and last was the fuel gauge that stopped. The fuel gauge stopped working just a couple of weeks after the battery gauge. I am also having problems with the daytime running lights not staying on periodically. The daytime running lights will go out about twice a year and mainly at night.

The instrument cluster stopped working, only the temp gauge and the fuel gauge works. The speedometer, tachometer, oil pressure gauges do not work. I believe general motors needs to issue a recall on this as this is a common problem with these vehicles.

I own a 2004 chevy trailblazer. I am having constant problems with the gas gauge indicating that either there is less gas then actual, or more gas then actual. I know there is an investigation going on with these vehicles but only for the years 2005-2007, mine is a 2004. This investigation should also include this year since the same problems are happening.

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.

On several occasion over the past year my fuel gauge in my 2004 chevrolet trailblazer lt has read inaccurately leading to breaking down due to the vehicle running out of gas while the gauge was still reading at least 1/4 tank moments before the engine stalls. On all occasions I was driving on the freeway the gauge showed 1/4 tank and then all od a suddenly dropped to e with the fuel warning light coming one. Within a few miles of this sudden drop and the warning light coming on the engine would stall due the vehicle being out of gas. I have complained to my local dealer on several occasions and all they have offered to me is to replace the sending unit, which in this model is integrated with the fuel pump at the cost of almost $800. This seem wrong to me. Now that I have read that this seems to be a problem on these types of vehicles I am even more upset that the local dealership told me my issue is an isolated issue and they have never heard of any problems with the fuel gauges in these vehicles.
