Filed May 1, 2017 · Electrical, Transmission · 80,000 miles · CA

My key will not come out of the ignition I had to unscrew and remove the bottom of my steering to push the button also all of my instrument gauge do not work including the speedometer and all gauges so I never know my temperature or fuel level, oil pressure they all are not working properly my speedometer only works sometimes. Also my engine is runny rough and I hear a vibration and ticking. My check engine light is and I'm getting code saying theres a leak in the fuel evap system. I have searched the internet and everyone has the same problems with their 2003 trailblazers. Why isn't chevrolet recalling these problems its fustrating they want several hundreds of dollars I cannot afford

The gas gauge started messing up/not reading right especially in the rain and then shortly after that the speedometer started doing the same thing. Now neither one will work at all. This started about two years ago and quit working all together about 1 year ago. I heard that this is happening to alot of trailblazers. This started while the vehicle was in motion.

There is a strong odor of gasoline vapors coming from the rear of the vehicle, a crack can be seen in the neck of the fuel tank. When filling the vehicle, fuel spills out of the tank from the crack. The fuel gauge cluster in the dash doesn't work. The blower on the A/C unit doesn't work on the highest (5) level. Also, the fan clutch went out causing the car to overheat severely. The fan does not engage, causing the water pump shaft to become damaged. Also, the rear driver side window quit functioning, despite buying an expensive new regulator and replacing it. Having researched the issues, I find that I am among hundreds, possibly thousands of unsatisfied people with the same problems.

Like many other, my problem is with the instrument panel/cluster. My fuel gauge doesn't work and my speedometer is all over the place...sometimes it seems to work fine, other times not at all, and sometimes it works but isn't accurate.

After driving the vehicle like normal, stopped at a gas station and when it was restarted, the fuel gauge, oil pressure gauge, battery gauge, tachometer, pretty much the entire instrument panel stopped working then came back on. Also, instead of reading driver like it normally does, the panel was reading unknown driver. Then as we were driving down the interstate home, the speedometer went to 0 and would not come back up. After we got home, the next day the panel worked fine. This has occurred numerous time since the first incident in 2011. I have read multiple forums and posts online from others stating it is the instrument panel cluster that may be the problem and there was a recall on other chevy makes but not the trailblazer. This is a very scary problem and should be covered by chevy due to the numerous other trailblazer owners with the same issue.

I, along with many others are experiencing major problems with the instrument panels on our chevrolet trailblazer. My mother traded hers in because her speedometer was going out. But my problem is much worse, my whole entire dashboard is out. My gas gauge doesn't work, my speedometer doesn't work, my oil pressure doesn't work, my thermostat doesn't work, nothing works. My cruise control acts up too.

I am a senior citizen I brought this car new. After one year I had to replace linc plate. Over the years everything has gone wrong with this car. Speedometer has not worked since aug. '08, gas gauge stopped oct. '11. Instrument cluster since 2010 and gm knows this is a defected part. Yet gm paid for this same defected part at their cost for the tahoe, but has not paid for the trailblazer. Why? Windows and doors do not unlock on command. Window wiper(rear) stopped working-I replaced that part. A/c comes on my itself. Thermostat failure. I think gm should stand behind their product. The only reason they would not is that they already know that they are producing substandard products that are not fit to be driven on the road.

I have a 2003 chevy trailblazer ext the fuel pump module has started to corrode, I knew something was wrong because of the strong odor of gasoline inside the vehicle and further investigation showed a leak of gas also.this is in addition to our gas gauge not working for the last 3 years. Upon talking to multiple rep's, gm claims they sent out letters in 2007 alerting the consumer to a potential problem. I am the second owner of this vehicle. I purchased this vehicle in september 2005. Gm stated that letters do get lost in the mail, when I stated we were not made aware of this situation. I was never informed of this potential hazard waiting to happen. Gm claims the service bulletin had parameters of 10 years or a 120, 000 miles which ever comes first. I have been in contact with the rep several times, and have not been successful. I do have 149,000 plus miles on this vehicle. I took the truck to the local dealership, they were claiming nothing has ever been documented on this type of vehicle. This is when I did my own research and found the service bulletin as mentioned above and the complaints of this same problem all through the internet blogs. It seems we are not getting anywhere and would appreciate some condsideration from gm and taking part of the responsibility for this problem. We had our children in this car when the gas was leaking out, what if it would have caught on fire? I would like to contact our regional representative for gm.

2003 chevrolet trailblazer - instrument cluster malfunction. Speedometer readings are erratic, fuel gauge is stuck above full level, water temperature gauge also has erratic readings. Gm recalled the suburban and tahoe for this issue but not the trailblazer.
