AT FIRST IT WAS READING 20 TO 55 MILES PER HOUR FASTER THAN I WAS ACTUALLY GOING AND AN HOUR LATER IT QUIT ALL TOGETHER. AT THIS TIME IT DOES NOT SHOE A READING AT ALL. VERY HARD TO DETERMINE SPEED WITHOUT A SPEEDOMETER IN HEAVY TRAFFIC AND CREATES A HAZARD TO OTHER DRIVERS AND MYSELF. *TR

REPORT DATE : OCTOBER 18, 2010 AT 09:14 AM SEARCH TYPE : VEHICLE YEAR : 2005 MAKE : CHEVROLET MODEL : TRAILBLAZER RESULTS : 1 | ALL RECORDS DISPLAYED NHTSA ACTION NUMBER: N/A NHTSA RECALL CAMPAIGN NUMBER: DP10001 N/A MAKE: CHEVROLET MODEL: TRAILBLAZER MANUFACTURER : GENERAL MOTORS CORP. YEAR : 2005 COMPONENT : FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP I BOUGHT MY 2005 TRAILBLAZER A LITTLE OVER A YEAR AGO. THE GAS GAUGE DOES NOT WORK. IT WOULD GO ALL THE WAY TO FULL AND THEN AFTER A COUPLE OF MILES IT WOULD GO TO "EMPTY." THE FUEL LIGHT COMES ON AND THE CAR WILL MAKE A LOUD BEEP TO LET YOU KNOW YOU ARE OUT OF FUEL. THE BEEP REALLY THROWS OFF YOUR CONCENTRATION TO THE ROAD AND IS VERY DISTRACTING. IT MAKES YOU TAP THE BRAKES WHICH COULD DEFINITELY LEAD TO AN ACCIDENT OR EVEN RUNNING OUT OF GAS. THIS IS A SERIOUS ISSUE AND NEEDS TO BE FIXED. *TR

MY SPEEDOMETER STOPPED WORKING AROUND SIX MONTHS AGO AND NOW THE OIL LEVEL GAUGE HAS STOPPED WORKING. FROM WHAT I'VE BEEN READING IT IS ONLY A MATTER OF TIME BEFORE THE FUEL GAUGE GOES OUT. THIS IS ABSURD THAT THIS HASN'T BEEN RECALLED SINCE THERE ARE COUNTLESS COMPLAINTS CONCERNING THE INSTRUMENT PANEL. *TR

FUEL GAUGE DOES NOT WORK ACCURATELY. I HAVE RAN OUT OF GAS TWICE BOTH TIMES THE GAUGE SHOWED THAT THERE WAS APPROX. 1/4 OF TANK REMAINING. OTHER TIMES AFTER FILLING THE GAUGE WILL DROP TO EMPTY AND THE LOW FUEL LIGHT AND CHIMES WILL COME ON WHILE DRIVING. VERY ANNOYING AND DISTRACTING. NO ACCIDENTS. *TR

STARTED WITH THE SERVICE AIR BAG MESSAGE (KNOWN ISSUE). THEN THE FUEL GAUGE ACTED UP AND FINALLY WENT TO E AND STAYED. NOW HAVE AND OCCASIONAL SURGE IN THE FUEL WHEN I HAVE THE BRAKE PRESSED (KNOWN ISSUES). SPEEDOMETER STARTING ACTING UP AND NO LONGER WORKS (KNOWN ISSUE). OH AND THE CHECK ENGINE LIGHT IS NOW ALWAYS ON. STARTED INTERMITTENTLY (AGAIN, KNOWN ISSUE). WAS TOLD $500 FROM DEALER WHEN I CALLED TO REPORT THE SERVICE AIR BAG MESSAGE. RECALL SHOULD APPLY TO THIS VEHICLE, I DON'T KNOW WHAT THE VEHICLE WENT THROUGH BEFORE I PURCHASED IT. CLOTH SEATS/LEATHER SEATS, THE SERVICE AIR BAG "SENSOR" IS STILL BROKE! DON'T HAVE THE MONEY TO FIX ALL THE "KNOWN" PROBLEMS. *TR

OUR 2005 CHEVY TRAILBLAZER'S LOW BEAM HEADLIGHTS HAVE BEEN REPLACED, THE WIRES WERE REPLACED AND WORKED LONG ENOUGH FOR ME TO GO OUT AT NIGHT. THE FIRST NIGHT I DID GO OUT, THEY STOPPED WORKING. I WAS STUCK OUT OF TOWN WITH MY LITTLE GIRL. THANK GOODNESS I WASN'T DRIVING OR IN A PLACE WHERE I DIDN'T HAVE CELL PHONE SERVICE(WHICH I DON'T HAVE CLOSE TO MY HOME). ALSO, OUR FUEL GAUGE DOESN'T WORK. WE'VE HAD IT REPAIRED AND IT WORKED FOR A SHORT PERIOD AS WELL, BUT DOESN'T WORK ANY LONGER. APPARENTLY, THESE TWO ISSUES ARE COMMON PROBLEMS THAT CHEVROLET NEEDS TO ADDRESS. A RECALL WOULD BE NICE. I HAVE TWO MORE PAYMENTS AND I DO NOT WANT TO BUY A NEW VEHICLE. NOR WOULD I FEEL COMFORTABLE SELLING THIS ONE AS IT IS. *TR
