Five problems related to other fuel system tank filling/charging have been reported for the 2007 Chevrolet Trailblazer. The most recently reported issues are listed below.
Fuel gauge read full tank when in fact the tank was empty. I ran out of gas in my driveway. When this occurred my on dash computer went crazy lighting up then turning off, when I put gas in the car and restarted several times the computer seemed to correct itself. Filling the tank the gauge read empty and remained that way for several days. The gauge operates intermittently. I recently had the fuel pump replaced after failure. The pump was replaced prior to this incident. I have scheduled the gauge repair with my dealer.
Vehicle stalled in traffic. Found no fuel in system even though fuel indicator noted a half tank. A week after this the low fuel light came on 15 miles after filling the tank. It has been on ever since and will not go off. We now have to keep track of fuel by using the trip computer.
After filling the gas tank at a local wawa gas station that I've used since owning the vehicle, I began to head home after work. As I left the parking lot and proceeded to merge onto the main highway my fuel gauge and fuel pump completely stopped working, truck had shut off as if it had run completely out of gas, which was not the case as I had just filled the 22 gallon tank with approx. 20 gallons of fuel. Thankfully I was able to keep the fuel pump operating after letting the truck sit for about 15 minutes, but the fuel gauge is no longer operational, but who knows how long the fuel pump will operate properly. Unfortunately my fiance and child now have to drive this vehicle due to the fact of our second vehicle being sold. It has now become a safety issue as there is no bearing on fuel level in vehicle. I've done research and found this issue to be a recurring theme for the model years 2005 - 2007 as well as seeing special policy letters sent out by gm to acquaintances with the same model year SUV for a rebated repair from a licensed gm dealer and yet I've not received one. Its now affecting the registration process for my vehicle to comply with state regulations. I do not feel as though any responsibility should fall on the consumer for a part that was poorly fabricated by the manufacturer.
Fuel gauge will drop to empty once it hits my half tank reading. I fill tank up and once the fuel gauge reaches half a tank, it will drop to empty as I am driving. It will move erratic while driving. Cannot tell how much gas I have once it reaches 1/2 tank. Afraid to stall while driving and running out of gas. Cannot afford to be filling up gas tank!!.
After filling my tank, the gage would drift between full and empty and then settle on the empty side. Now it does not even move from that location!.
