NHTSA Complaint #11339673 — 2015 GMC ACADIA

AIR CONDITIONING ISSUE: WITHIN THE FIRST 5,000 MILES, THE REAR AIR CONDITIONING BLOWER BEGAN TO MAKE UNUSUAL SQUEAKING / VIBRATING NOISES. THIS CONTINUED INTERMITTENTLY FOR THE UNTIL ULTIMATELY THE ENTIRE CAR AIR CONDITIONING SYSTEM FAILED AT 45,000 MILES. THE ISSUE WAS BROUGHT TO THE ATTENTION OF THE CERTIFIED GMC CERTIFIED SERVICE CENTER AT 11 MONTHS OF OWNERSHIP/10,000 MILES AND 27 MONTHS OF OWNERSHIP/29,000 MILES; THEY WERE UNABLE TO REPLICATE THE ISSUE. AT THE 27 MONTH VISIT THE GMC CERTIFIED SERVICE CENTER (CENTRAL BUICK GMC OF NORWOOD) ASSERTED THIS WOULD BE COVERED IF THE PART SUBSEQUENTLY FAILED. UPON FAILURE, THAT SERVICE CENTER REFUSED TO HONOR THAT COMMITMENT. PER GM SERVICE BULLETIN 16-NA-046, THE BLOWER MOTOR MAY EMIT BRUSH DUST THAT CONTAINS SOME COPPER PARTICLES. THESE PARTICLES COULD LEAD TO ACCELERATED CORROSION TO THE AUXILIARY EVAPORATOR AND A SMALL REFRIGERANT LEAK, WHICH ULTIMATELY LEADS TO FAILURE OF THE AIR CONDITIONING SYSTEM. HOWEVER, THE GMC CERTIFIED SERVICE CENTER ASSERTED THAT THE FAILURE OF THE SYSTEM RELATED SOLELY TO THE FAILURE OF THE REAR AUXILIARY UNIT AND ENTIRELY UNRELATED TO ANY ISSUES FROM THAT MAY HAVE EXISTED WITHIN THE BLOWER IN CONTRADICTION TO THE SERVICE BULLETIN.
