problem #3

Trailblazer EXT 4WD 6-cyl

  • Automatic transmission

Gas gauge has not been reliable. Low gas light will come on and go off while driving and does not register addition of gas accurately.

I purchased my 04 trailblazer in may of 07. Up until July there where no problems. Since then my speedometer and gas gauges have been acting up. On many occasions they give the wrong readings. I have been stopped twice for speeding when I did not think I was because of the wrong reading. Last week on 5 Sep 07 the speedometer completely froze giving me no reading at all. Since then the needle has started moving but is no where near the correct reading.

The gas gauge does not work properly. I have talked to several owners of trailblazers and they have the same problem.
