All Engine And Engine Coolingcooling System Complaints
THERMOSTAT HAS FAILED TWICE DURING LONG TRIPS. THIS CAUSES THE ENGINE TO RUN HOT OR COLD. I AM ON MY THIRD ONE AND HAVE CONCLUDED IT MUST BE A DESIGN DEFECT. FAILURE OF THIS COMPONENT MAY CAUSE THE ENGINE TO FAIL AND THUS STRAND THE DRIVER. *TR
ANTIFREEZE IS LEAKING FROM REAR HEATER CORE. CAUSED MY ENGINE TO OVERHEAT. FLUID LEAKS AT A FAIRLY RAPID RATE. IN DOING RESEARCH I FOUND THAT THEY CHANGED THE HEATER CORE SO THIS REPAIR COSTS AN EXTRA $500 FOR PARTS TO RETROFIT A NEW HEATER CORE. IF THERE IS A FLAW IN THE DESIGN WHY ISN'T THIS A RECALL? IT COULD CAUSE ENGINE DAMAGE. I CALLED GM WITH NO LUCK. *TR
2003 TRAILBLAZER TRANSMISSION LINES. COOLANT LINES RUSTED AT THE FACTORY CONNECTION. MAJOR FLUID LOSS, HAD TO REPAIR IMMEDIATELY. *TR
TRAILBLAZER OVER HEATED ABOUT A YEAR AGO, RAN DIAGNOSTICS-CHANGED THE FAN CLUTCH ASSY, WORKED FOR TWO MONTHS. OVER HEATED AGAIN- MORE DIAGNOSTICS-WARRANTY FAN CLUTCH, WORKED FOR A WEEK- WARRANTY FAN CLUTCH AGAIN AND CHANGED THE COOLANT TEMP SENSOR- STILL OVER HEATING. DEALERSHIP WANTED TO CHANGE THE FAN CLUTCH AGAIN- I REFUSED BECAUSE THIS IS ABOUT TO RUN ME INTO THE POOR HOUSE. *TR
I OWN A 2003 CHEVY TRAILBLAZER LT @ 35,825 MILES I REPORTED MY VEHICLE BINDS UP ON TURNS & OF COURSE THE GARAGE FOUND NOTHING (DROVE IT 20 MILES FOR COMPARISON @ THE TIME). SO NOW THAT I AM UP TO 82,090 MILES NOW I MENTION SUSPENSION ISSUES STILL & OF COURSE THEY FIND BOTH LOWER BALL JOINTS NEED REPLACED @ $320.06 & LEFT OUTER TIE ROD END BROKEN @ $170.80. ALSO THEY INFORM ME I NEED TO REPLACE 3 OF MY 4 STABILIZER BAR LINKS ARE LOOSE & RATTLING @ AN ESTIMATE OF $320.00 (HAVEN'T DONE YET) ALSO, I HAVE LOOKED ON A WEBSITE CALLED MYCARSTATS.COM & FOUND MANY OTHERS WITH THESE SAME ISSUES WITH THIS VEHICLE @ MUCH LOWER MILEAGE & WHERE TIE ROD ISSUE CAUSED AN ACCIDENT -- THEY WEREN'T AS LUCKY AS ME. ALSO PEOPLE I WORK WITH WHO HAVE THIS SAME YR & MODEL VEHICLE...
