2007 Chevrolet Trailblazer fuel system, other problems

“MY FUEL GAUGE METER DOESN'T WORK. WHEN EVER I START THE CAR, THE FUEL METER DROPS TO EMPTY. ALSO, ONE DAY IN SUMMER OF 2011, MY DRIVER-SIDE POWER MODULE JUST STOPPED WORKING. THE POWER WINDOWS AND LOCKS NO LONGER WORK FROM MY DRIVER-SIDE DOOR. I AM CONCERNED I WILL RUN OUT OF GAS ON THE INTERSTATE OR HIGHWAY AND CAUSE A WRECK. I ALSO CAN NOT SEE IN THE MORNINGS FROM MY WINDOW BECAUSE IT GETS FOGGY AND THERE IS NO WAY TO ROLL MY WINDOW DOWN. THIS IS A SERIOUS SAFETY HAZARD. *JS”

“AT FIRST, FUEL GAUGE WOULD READ FULL AFTER FILL UP. THEN AT 1/2 FULL MARK, THE GAUGE WOULD SLOWLY GO DOWN AND READ EMPTY. LOW FUEL WARNING LIGHT WOULD COME ON AND ALERT CHIMES. AFTER 2 WKS IT WOULD READ FULL AFTER FILL UP BUT NOW IT GOES DOWN TO EMPTY AFTER 2-3 BLOCKS W/LOW FUEL LIGHT ON AND ALERT CHIME. NOW IT JUST REGISTERS AT A LOW LEVEL FUCTUATING AND TRIPING THE LOW FUEL WARNING LIGHT AND ALERT CHIMES (ON AND OFF) OVER AND OVER AGAIN AS I DRIVE. THERE IS NO ACTUAL ACCURATE READING FROM THE GAUGE AT ALL. I'M DRIVING AROUND BY USING THE TRIP-OMETER TO DETERMINE WHEN TO FILL UP AGAIN. TOO EXPENSIVE TO FIX. *JS”

“THE FAILURE IS THE FUEL GAUGE, I HAVE RAN OUT OF GAS THREE TIMES BECAUSE OF THIS ISSUE. NOTHING HAS BEEN DONE WITH THIS AS OF YET, WILL COST $600 TO REPAIR, EVERYONE WITH THIS TYPE OF TRUCK HAS THIS ISSUE. *TR”

“2007 CHEVY TRAILBLAZER. GAS GAUGE PERIODICALLY GOES FROM FULL TO EMPTY EVEN THOUGH TANK IS FULL. NO REAL RHYTHM TO THE MALFUNCTION WHICH KEEPS US FROM KNOWING HOW MUCH GAS IS ACTUALLY THERE. *TR”

“TL* THE CONTACT OWNS A 2007 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 10 MPH, THE FUEL GAUGE LIGHT ILLUMINATED ON THE INSTRUMENT PANEL AND A WARNING ALARM BEGAN TO SOUND, NOTIFYING THE CONTACT THAT THE FUEL TANK WAS EMPTY. THE CONTACT ALSO STATED FUEL HAD BEEN RECENTLY ADDED TO THE VEHICLE AND THE FUEL TANK WAS NOT EMPTY. THE FUEL GAUGE READING WOULD FLUCTUATE FROM EMPTY TO FULL WHILE DRIVING AT ANY SPEED. THE VEHICLE WAS NOT TAKEN TO THE DEALER FOR DIAGNOSTICS. THE VEHICLE WAS NOT REPAIRED. THERE WAS AN INVESTIGATION UNDER NHTSA ACTION NUMBER: DP10001 (FUEL SYSTEM, OTHER:STORAGE:FUEL GAUGE SYSTEM), THAT MAY BE RELATED TO THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 37,000. UPDATED 8/29/11 *CN UPDATED 09/20/11”

“2007 TRAILBLAZER FUEL GAUGE READS EMPTY EVEN AFTER FUELING. RESEARCH SHOWS IT IS A PREVALENT FAILURE IN THIS MODEL. MONITORING THE ODOMETER IS THE ONLY WAY TO ESTIMATE REMAINING FUEL. IT CAN BE DANGEROUS NOT KNOWING CORRECT AMOUNT OF FUEL REMAINING. *KB”
