NHTSA Complaint #11202870 — 2014 GMC ACADIA

ON ONE, APPROXIMATELY 200-MILE TRIP LAST YEAR, THE ELECTRICAL SYSTEM IN OUR ACADIA COMPLETELY WENT OUT (INCLUDING ALL GUAGES, TURN SIGNALS, ETC.) THREE SEPARATE TIMES. WE WERE DRIVING ON INTERSTATE ROADWAYS, AND THE VEHICLE COULD STILL BE DRIVEN. THE SYSTEM REBOOTED EACH TIME AFTER A FEW MINUTES. ULTIMATELY, MY WIFE ENDED UP STRANDED AS THE VEHICLE WOULD NOT START DUE TO ELECTRICAL SYSTEM FAILURE AFTER SHE HAD PARKED IT DURING A SEPARATE TRIP. OUR GM DEALERSHIP INFORMED US THAT THE REAR OBJECT DETECTION MODULES HAD CORRODED, AND THAT "EVERYONE HAS THIS PROBLEM." THE CORROSION CAUSED A CASCADE FAILURE OR THE ENTIRE SYSTEM, WHICH IS DEFINITELY A SAFETY HAZARD. GM REPLACES THESE MODULES WITH NON-CORRODING ONES NOW, AFTER WE PAID $992.52 TO HAVE THEM REPLACED. I CONTACTED AUTUMN AT GM CUSTOMER SERVICE, AND SHE SAID THAT THERE IS NOW SPECIAL COVERAGE FOR THIS PROBLEM THAT BEGAN ON 4/2/19. HOWEVER, OUR VEHICLE IS OVER THE 80,000-MILE WARRANTY FOR THIS PROBLEM.
