NHTSA Complaint #10907013 — 2014 CHEVROLET TRAVERSE

OVER THE PAST 2 YEARS 10 MONTHS I HAVE LOST THE COOLANT IN MY AIR CONDITIONER. THEY HAVE FILLED IT SEVERAL TIMES, ADDING DYE, BUT HAD NOT BEEN ABLE TO FIND THE LEAK EVEN THOUGH THEY ACKNOWLEDGED IT WAS LOST. SINCE THE WARRANTY WAS RUNNING OUT WE TOOK IT IN AGAIN AFTER DYE HAD BEEN ADDED AND THEY FINALLY STARTED TO LOOK AT THE EVAPORATORS. THEY COULD NOT THOROUGHLY INSPECT THE FRONT EVAPORATOR SINCE A FULL INSPECTION REQUIRES REMOVAL OF THE DASHBOARD. THEY LOOKED AT THE REAR EVAPORATOR AND FOUND SOME CORROSION (WITH A MIRROR) AND A PINHOLE LEAK.. WHEN THEY WENT TO ORDER A NEW PART AND GM HAD A FOOTNOTE THAT IF THEY WERE ORDERING A REPLACEMENT EVAPORATOR THEY SHOULD ALSO ORDER AND REPLACE THE BLOWER MOTOR SINCE THE COPPER IN THE MOTOR BRUSHES WAS ATTACKING THE ALUMINUM EVAPORATOR. (THE MORE YOU USED THE AC, THE SOONER IT WOULD SHOW UP AND CAUSE THE CORROSION. THIS IS WHY EACH TIME IT TOOK ABOUT 8 MONTHS FOR THE COOLANT TO LEAKED OUT.) BOTH REAR AC PARTS WERE REPLACED BUT THE BLOWER MOTOR FOR THE FRONT EVAPORATOR WAS NOT REPLACED AND THIS MAY ALSO BE GOING BAD. WE WON'T KNOW FOR A WHILE SINCE WE WON'T BE USING THE AC DURING THE FALL AND WINTER MONTHS. ALSO, IF THESE MOTORS CORRODE THE ALUMINUM EVAPORATOR, IT COULD EASILY ATTACK OTHER ALUMINUM PARTS IN THE CAR AND OF COURSE THE COOLANT HAS BEEN LEAKING INTO THE INTERIOR OF THE CAR, BOTH OF WHICH WHICH MAY BE A MAJOR SAFETY CONCERN.CHEVROLET WAS AWARE OF THE ISSUE BUT DID NOT TO RECALL THESE CARS SINCE GENERALLY THE ISSUE MAY NOT SHOW UP UNTIL THE CAR IS OUT OF WARRANTY. I HAVE E-MAILS FROM JOHN THORNTON CHEVROLET'S SERVICE MAN ALONG WITH A PICTURE OF THE EVAPORATOR BUT HAVE NOT BEEN ABLE TO ATTACH THEM TO THIS COMPLAINT FORM.
