THIS IS THE 2ND TIME THAT THE REAR WINDOW HAS LITERALLY "BLOWN UP" ON THIS PARTICULAR VEHICLE.

THIS IS THE 2ND TIME THAT THE REAR WINDOW HAS LITERALLY "BLOWN UP" ON THIS PARTICULAR VEHICLE. THE FIRST TIME MY WIFE WAS AT A BUSY GROCERY STORE WHEN SHE STARTED TO LOWER THE BACK HATCH AND THE ENTIRE BACK WINDOW EXPLODED. IT WAS SO LOUD AND DEVASTATING THAT SHE THOUGHT SOMEONE HAD FIRED A SHOTGUN INTO THE BACK WINDOW! THE DEALERSHIP REPLACED THE WINDOW IN 2008 AS A COURTESY. LESS THAN TWO WEEKS AGO IT HAPPENED AGAIN AS I DROPPED MY TWO YOUNG CHILDREN OFF AT SCHOOL. I OPENED THE GATE, REMOVED THEIR SCHOOL BAGS, SHUT THE HATCH AND TOOK APPROXIMATELY 3 STEPS AND KAPOWW! THE ENTIRE WINDOW EXPLODED RIGHT IN THE SCHOOL'S BUS CIRCLE. THE EXPLOSION WAS SO GREAT THAT IT EVEN BLEW ONE OF THE WINDOW LIFT CYLINDERS RIGHT OUT INTO THE ROAD!! THE WIFE WASN'T KIDDING...THE SOUND IS DEAFENING. CONTACTED GM AND WAS TOLD THAT A TECHNICAL BULLETIN WAS ISSUED 03-08-48-006G REV. FEB 25TH 2010) REGARDING THE REPLACEMENT OF THE WINDOW CLIPS. I WAS ISSUED A CASE NO. IN ESSENCE I WAS TOLD THAT IF THE CLIPS WEREN'T REPLACED IT WOULD HAPPEN AGAIN. WELL UNFORTUNATELY THIS BULLETIN WASN'T AVAILABLE IN 2008 SO IT HAPPENED AGAIN. CONTACTED CUSTOMER SERVICE AGAIN, WAS TOLD VEHICLE HAS TOO MANY MILES, IS NO LONGER UNDER WARRANTY, THE ORIGINAL REPAIR WAS ONLY GOOD FOR 1 YEAR, AND THAT THIS IS "MY BABY' TO DEAL WITH. BUT THE SERVICE REP OFFERED ME $1000,00 GM LOYALTY BUCKS (SOMETHING LIKE THIS) THAT I COULD USE ON A NEW GM VEHICLE. I AM FURIOUS TO SAY THE LEAST AND WHEN I ASKED FOR THE NAME AND NUMBER OF THE CUSTOMER SERVICE REP HE TOLD ME THAT I COULD HAVE THE NAME, BUT NOT THE NUMBER, AS HIS SUPERVISOR DOESN'T SPEAK TO CUSTOMERS!!!! *TR

I HAVE A 2005 CHEVY TRAILBLAZER WHAT A HUNK OF JUNK ABOUT 6 MONTHS AGO THE FUEL GAUGE STOPPED WORKING , WHICH I READ IS A KNOWN PROBLEM WITH MANY OF THE 2005 MODELS ITS A PROBLEM BUT I AM DEALING WITH IT UNTIL I RUN OUT OF GAS LATE ON NIGHT WITH MY KIDS AND SOME TERRIBLE HAPPENS TO US! BUT THAT IS NOT THE MAJOR COMPLAINT NOW. ON 2 SEPERATE OCCASIONS MY SPEEDOMETER JUST STOPS WORKING, EITHER I AM GOING ZERO OR I AM GOING 120 MILES A HOUR, WHAT A MAJOR PROBLEM FOR A PERSON WHO DOES A GREAT DEAL OF HIGHWAY TRAVELING. SO WHAT ARE MY OPTIONS IT SEEM THAT THERE ARE NUMEROUS COMPLAINTS REGARDING BOTH OF THESE ISSUES I KNOW GM DOESNT PROBABLY SEE THEM AS A SAFTEY ISSUE BUT I DO. I TERRIFIED OF RUNNING OUT OF GAS I USUALLY TRAVELING ALONE OR WITH MY TEENAGE DAUGHTER. BUT O WONT BE ABLE TO AFFORD THE GAS BECAUSE I HAVE TO PAY ALL OF THOSE SPEEDING TICKETS. *CN
I HAVE A 2005 CHEVY TRAILBLAZER AND IT HAS MANY PROBLEMS. BUT THE MOST DANGEROUS, AT THIS POINT, IS THE SPEEDOMETER STOPS WORKING. SOMETIMES, IT WON'T GET OFF OF ZERO. OTHER TIMES, IT SHOWS THAT I AM GOING OVER 120 MPH, WHEN IN FACT, I AM GOING WITH FLOW OF TRAFFIC. AT OTHER TIMES, IT SHOWS EITHER 15 TO 20 MILES ABOVE OR BEL…

I HAVE A 2005 CHEVY TRAILBLAZER AND IT HAS MANY PROBLEMS. BUT THE MOST DANGEROUS, AT THIS POINT, IS THE SPEEDOMETER STOPS WORKING. SOMETIMES, IT WON'T GET OFF OF ZERO. OTHER TIMES, IT SHOWS THAT I AM GOING OVER 120 MPH, WHEN IN FACT, I AM GOING WITH FLOW OF TRAFFIC. AT OTHER TIMES, IT SHOWS EITHER 15 TO 20 MILES ABOVE OR BELOW THE SPEED I AM ACTUALLY DRIVING. THERE IS NO COMMON DENOMINATOR AS TO WHEN OR IF THE PROBLEM STARTS OR STOPS. IT IS VERY, VERY RANDOM. THE COST TO FIX WILL BE OVER $450.00. THERE ARE MANY OTHER TRAILBLAZER OWNERS THAT ARE HAVING THIS SAME PROBLEM. THE SPEEDOMETER PROBLEM COULD BE VERY, VERY DANGEROUS AS THE DRIVER DOES NOT KNOW HOW FAST, OR SLOW, THEY ARE ACTUALLY DRIVING. *TR
TRANSMISSION LINE LEAK. PASSENGER SIDE FENDER WELL. CORROSION ON 1 LINE. *TR
I HAVE A 2005 TRAILBLAZER EXT. THE GAS GAUGE AND SPEEDOMETER ARE BOTH BROKEN. I DID NOT REALIZE THIS UNTIL I RAN OUT OF GAS IN THE MIDDLE OF A BUSY THREE LANE HIGHWAY. MY SPEEDOMETER DID NOT BECOME CLEAR UNTIL I FOUND MYSELF AT A COMPLETE STOP WITH THE SPEEDOMETER REGISTERING 30 MPH. *TR

I AM SCARED THAT THE VEHICLE WILL RUN OUT OF GAS AND SHE COULD GET INTO AN ACCIDENT WITH MY KIDS IN THE CAR. I READ MANY COMPLAINTS ABOUT THE LEVEL SENSOR GOING OUT AND I THINK THAT THIS IS A DEFECT IN THE PART. *TR
MY FUEL GAUGE IS NOT WORKING PROPERLY. WHEN I FILL UP WITH GAS, IT STATES I AM ON EMPTY IMMEDIATELY AFTER FUELING. TAKES SEVERAL DAYS TO REGISTER. I DON'T TRUST IT AND AM CURRENTLY JUDGING HOW FULL THE TANK IS BY MILES DRIVEN. *TR
