MY 2005 CHEVY TRAILBLAZER IS COMPLETELY GOING CRAZY IT SEEMS EVERYTHING ELECTRICAL IS GOING WRONG WITH IT. I AM AFRAID TO LET MY WIFE OR MY KIDS DRIVE IN IT BECAUSE I NEVER KNOW WHAT'S GOING TO GO WRONG WHILE DRIVING. MY WHOLE GAS SYSTEM IS GONE FROM FUEL LEVEL INDICATOR TO THE GAUGE. MY ENTIRE DASHBOARD IS NOT WORKING. LIGHTS ARE GOING OUT. WHAT IS CRAZY ABOUT THIS IS THAT I AM ONE OF THOUSANDS THAT THIS IS HAPPENING TO. CHEVY NEEDS TO FIX THIS PROBLEM BEFORE SOMEONE DOES GET KILLED. WAITING FOR FATALITIES BEFORE MAKING CHEVY FIXES THERE AWFULLY MADE VEHICLES IS UNACCEPTABLE. I UNDERSTAND THE SITUATION OUR ECONOMY IS IN BUT THESE THOUSANDS OF TRAILBLAZER OWNERS THAT ARE HAVING THESE PROBLEMS SHOULDN'T BE PAYING THOUSANDS OF DOLLARS TO BE GETTING THERE ENTIRE ELECTRICAL PROBLEM FIXED. I DO NOT KNOW ONE OWNER OF A 2006 TRAILBLAZER THAT DOES NOT HAVE THIS SAME PROBLEM. IT IS UNETHICAL AND CHEVY INSTEAD OF STEPPING UP AND FIXING THERE PROBLEM ARE MAKING THERE LOYAL CUSTOMERS SPEND THOUSANDS OF DOLLARS FIXING THERE MISTAKE. IT IS TRULY SAD THAT I DO NOT TRUST TAKING MY VEHICLE WITH MY FAMILY IN IT BECAUSE OF BEING AFRAID MY VEHICLE WILL FAIL TO DRIVE OR MALFUNCTION. PLEASE HOLD CHEVY ACCOUNTABLE AND MAKE THEM FIX OUR POORLY MAD AND UNSAFE VEHICLES SO WE CAN FEEL SAFE DRIVING OUR FAMILY AROUND AGAIN. *TR

I HAVE AN 05 CHEVROLET TRAILBLAZER EXT 4.2L WITH 90000 MILES AND LAST MARCH THE FUEL GAUGE QUIT WORKING BUT NOT BEFORE WE RAN OUT OF FUEL 2 TIMES NOT KNOWING THAT THE GAUGE WAS GIVING A FALSE READING.THE OCCURRENCE HAPPENED ON THE FREEWAY AND ONCE ON A BUSY STREET. VERY SCARY WHEN YOU HAVE THREE INNOCENT LITTLE GIRLS UNDER THE AGE OF 3 THAT RIDE IN THE VEHICLE. FROM DOING MY RESEARCH I SEE THIS A VERY COMMON PROBLEM AND A DANGEROUS ONE AT THAT BECAUSE WHEN THE TRUCK STOPS RUNNING YOU LOSE POWER STEERING AND POWER BREAKING. *TR
SPEEDOMETER AND OTHER INSTRUMENT PANEL ITEMS ARE NOT FUNCTIONING. MAIN ISSUE IS THE SPEEDOMETER AS I HAVE NO IDEA HOW FAST I AM GOING. *TR
