Two problems related to dashboard failed have been reported for the 2007 Chevrolet Trailblazer. The most recently reported issues are listed below.
Fuel gauge failure, inaccurate reading. Fuel guage stays on empty. Driver has to rely on tripometer to guess range to determine when to fill gas tank.
Filled my tank and drove away the morning of the incident. While driving later that day my fuel gauge started going down while driving. It went to empty the low gas indicator light came on and it stayed that way for a few minutes before returning to full. This only happened 1x so far recently. I've also had problem with all the gauges going out while driving. Speedometer/fuel/ electrical/tach etc. Had to turn off the vehicle and restart to reset these functions in the past. 2-3x an had onstar run diagnostics. The electric stability control has also been coming on/off intermittently quite frequently at startup and at other times while driving. I've seen similar complaints on chat boards but few have take the steps to document them beyond the postings. There are many similar complaints on the web. Thank you.
