MY SPEEDOMETER HAS QUIT WORKING. IT WILL REGISTER 30MPH AND I'M PROBABLY GOING 70 WHEN I'M KEEPING UP WITH THE TRAFFIC ON THE HIGHWAY. MOST OF THE TIME IT DOESN'T WORK AT ALL. THIS JUST STARTED ON THE 25TH OF DECEMBER. WE HAVE NOTICED ON THE INTERNET THAT THIS IS HAPPENING TO SEVERAL GM VEHICLES. THERE IS OTHER RECALLS ON THESE OTHER VEHICLES AND WE THINK THE 2005 TRAILBLAZER SHOULD ALSO BE INCLUDED. *TR
SPEEDOMETER NO LONGER WORKING ON MY MOTHER'S 2005 CHEVROLET TRAILBLAZER. VERY HAZARDOUS. AIR/HEAT WILL NOT BLOW IN THE FRONT VENTS AND DO NOT WORK ON SETTING NUMBER 5. *TR

I STARTED MY CAR UP THIS MORNING WHEN I NOTICED THAT I HAD ONLY 1/4 TANK OF GAS LEFT, SO I DROVE DOWN TO THE GAS STATION AND FILLED UP UNTIL IT CLICKED. I GOT BACK IN AND STARTED THE CAR AND THE NEEDLE WAS MOVING VERY SLOW THEN IT STOPPED AT 1/4 OF A TANK AND I WAS LIKE THAT IS IMPOSSIBLE. AT FIRST I WAS PISSED BECAUSE I JUST SPENT $77 FILLING UP. THEN I WAS SCARED I THOUGHT MAYBE I HAD A HOLE IN MY FUEL TANK SO I PULLED OVER AND SAW THAT THERE WAS NOTHING LEAKING. IMMEDIATELY DRIVING TO THE AUTO SHOP I AM INFORMED THAT THE FUEL GAUGE ISN'T WORKING AND WOULD NEED TO BE REPLACED. SINCE WE ARE STATIONED OVERSEAS I WOULD BE PAYING ABOUT 400 TO 500 EUROS WHICH ISN'T HAPPENING ANYTIME SOON. I WAS TOLD TO KEEP TRACK OF MY MILEAGE BY SETTING THE ODOMETER EVERYTIME I FILLED UP. RUNNING OUT OF GAS IS NOT AN OPTION IN GERMANY THERE ARE FINES AND EVEN JAIL TIME BECAUSE ITS CALLED NOT BEING RESPONSIBLE. IT CAN ALSO CAUSE ACCIDENTS AND TRAFFIC JAMS IF MY CAR WAS TO JUST RUN OUT OF GAS ON THE AUTOBAHN. THIS IS A VERY COMMON PROBLEM AND NEEDS TO BE FIXED BY GM. I GUESS THAT ISN'T AN OPTION UNTIL SOMEONE GETS HURT OR WORSE ACTUALLY DIES. *TR
2005 CHEVY TRAILBLAZER HAS A PROBLEM WITH THE SPEEDOMETER READING INACCURATELY. THE READINGS ARE ERRATIC. *TR
THE SIDE CONTROL PANEL FOR THE DRIVER'S SEAT HAS COME LOOSE AND HAS BE COME A CONCERN THAT IT MAY FALL OFF COMPLETELY AND ONTO MY LEGS AS I'M DRIVING. I WEIGHT ABOUT 145 AND DON'T BELIEVE THIS SHOULD BE HAPPENING TO A VEHICLE THAT IS ONLY 3 YEARS OLD. *TR
ON TODAY I WENT TO FILL UP MY TANK DUE TO HURRICANE IKE. BEFORE I WENT TO THE GAS STATION ALL GAUGES WERE FINE BUT WHEN I RETURNED TO WORK I NOTICED THAT THE GAS GAUGE WAS ONE WITH THE LIGHT LIT. I TURNED OFF THE ENGINE AND TURNED IT BACK ON AND IT STAYED THE SAME. THIS SHOULD BE FIXED AND COVERED SOME TYPE OF RECALL. *TR

THE REAR LIFTGATE WINDOW OF MY 2005 CHEVROLET TRAILBLAZER EXT SHATTERED FOR NO APPARENT REASON AT ALL. MY WIFE WAS CLOSING THE LIFTGATE (THE GLASS WAS NOT OPEN), PULLED THE LIFTGATE DOWN A FEW INCHES, AND THE ENTIRE REAR LIFTGATE WINDOW EXPLODED SENDING GLASS ALL OVER MY WIFE AND OUR 4 YEAR OLD SON, NOT TO MENTION MY DRIVEWAY, SIDEWALK, ETC. ACCORDING TO DIFFERENT SITES THAT I HAVE VISITED ON THE INTERNET, THIS IS QUITE A COMMON OCCURRENCE. MIGHT I ADD THAT THIS VEHICLE HAD NOT BEEN DRIVEN OR MOVED FROM ITS' PARKING SPOT SINCE SUNDAY 8/24/2008 AND WAS NOT DRIVEN TODAY. WE OPENED THE REAR LIFTGATE TO PUT AN ITEM INTO THE BACK OF THE VEHICLE, WENT TO SHUT THE LIFTGATE, AND THE ABOVE OCCURRED. *TR
