“TL* THE CONTACT OWNS A 2002 CHEVROLET TRAILBLAZER. WHILE DRIVING AT VARIOUS SPEEDS, FLUID WAS LEAKING FROM THE VEHICLE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO STATED THAT THERE WAS RUST IN THE TRANSMISSION LINE AND FLUID LEAKED ON THE CATALYTIC CONVERTER. THE LOCAL DEALER WAS NOT CONTACTED. THE MANUFACTURER WAS CONTACTED BUT NO FURTHER ASSISTANCE WAS PROVIDED. THE FAILURE MILEAGE WAS 120,000.”

“ELECTRICAL UNDER DASH SHORTING OUT. CAUSING ACCESSORY PLUG TO SHOOT SPARKS AS WELL AS CAUSING DASH LIGHTS TO GO OUT, AND FRONT PANEL TO STOP WORKING. AC ELECTRICAL QUIT WORKING AFTER. 4WHEEL DRIVE SHIFTS RANDOMLY IN AND OUT OF 2 AND 4 WHEEL DRIVE, CAUSING THE TRANSMISSION TO GET STUCK IN NEUTRAL. MOTOR SOLENOIDS AND SENSORS KEEP FAILING AND SHORTING OUT DUE TO ELECTRICAL ISSUES. VEHICLE UNSAFE TO DRIVE.”

“TL* THE CONTACT OWNS A 2002 CHEVROLET TRAILBLAZER. WHILE DRIVING APPROXIMATELY 35 MPH, THE TRANSMISSION SHIFTED OUT OF GEAR AND THE ANTI-THEFT LOCK AND BATTERY WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DETERMINED THAT THE TRANSMISSION NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE CONTACT ALSO MENTIONED THAT THE FUEL GAUGE DISPLAYED AN INACCURATE READING WHEN THE FUEL TANK WAS FULL. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 143,000.”

“TL* THE CONTACT OWNS A 2002 CHEVROLET TRAILBLAZER. WHILE OPERATING THE VEHICLE, ALL THE EXTERIOR LIGHTS RANDOMLY SHUT ON AND OFF. WHILE DRIVING AT VARIOUS SPEEDS, THE TRANSMISSION WOULD SUDDENLY SWITCH TO FIRST GEAR AND CAUSED THE SPEED TO SUDDENLY REDUCE. THE VEHICLE WOULD NOT OPERATE IN REVERSE. AFTER SHUTTING THE VEHICLE OFF AND RESTARTING THE ENGINE, THE VEHICLE WOULD OPERATE NORMALLY. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO WAS UNABLE TO DIAGNOSE THE CAUSE OF THE FAILURES. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 171,000.”

“THE COOLING LINES FROM THE TRANSMISSION OF THE 2002 CHEVROLET TRAILBLAZER EXIT THE TRANSMISSION NEXT TO THE CATALYTIC CONVERTER. A PORTION OF THE LINES ARE COVERED WITH A PROTECTIVE AND LOOSE FITTING COVER WHICH APPEARS TO BE ALUMINUM ALMOST LIKE A TIN FOIL. THIS COVERING CREATES AN AREA WHERE MOISTURE COLLECTS CAUSING THE LINES TO RUST. EVENTUALLY THE LINES START TO LEAK TRANSMISSION FLUID. WHEN THE VEHICLE IS IN MOTION THE FLUID IS BLOWN ONTO THE CATALYTIC CONVERTER AND COULD START A FIRE UNDER THE VEHICLE EXPOSING THE VEHICLE OCCUPANTS TO EXTREME DANGER. AT FIRST I THOUGHT THE LEAK WAS OIL FROM THE ENGINE, BUT UPON CHECKING CLOSER, I FOUND THE TRANSMISSION LINES LEAKING. THE PLACEMENT OF THE TRANSMISSION COOLING LINES ARE VERY CLOSE TO THE CONVERTER AND IF EXCESSIVE FLUID IS SPLATTERED ON THE CONVERTER, A FIRE COULD RESULT. THE VEHICLE WAS STATIONARY WHEN THE LEAK WAS NOTICED. HOWEVER, THE FLUID WAS FOUND AFTER BEING ON THE HIGHWAY AT 70MPH SPLATTERED ON THE UNDERCARRIAGE AND SURROUNDING AREA OF THE VEHICLE. SPEAKING WITH AAMCO MECHANICS WHO REPLACED THE LINES, THEY FELT IT IS A REAL FIRE HAZARD. THIS SEEMS TO BE A DESIGN DEFECT. WHAT BROUGHT MY ATTENTION TO…”
