NHTSA Complaint #11081572 — 2012 BMW X5

THE DIESEL EXHAUST FLUID PASSIVE TANK IN MY BMW X5 HAS FAILED, WHICH FROM WHAT I'VE READ IN MANY FORUMS IS AN UNACCEPTABLY COMMON OCCURRENCE. WHILE TAKING THE CAR INTO THE DEALERSHIP TO HAVE THREE OTHER RECALLS ADDRESSED I ASKED ABOUT THE TANK BEING COVERED IN THE EXTENDED EMMISSIONS WARRANTY ON THE CAR. THEY INFORMED ME THAT THE MAIN DIESEL EXHAUST FLUID TANK IS COVERED (WHICH THEY REPLACED BECAUSE IT HAD FAILED TOO), BUT THE RESERVE OR PASSIVE TANK WAS NOT COVERED UNDER THE WARRANTY. NOW THERE IS A COUNTDOWN ON THE DASH THAT IF I DRIVE OVER 900 MILES WITHOUT FIXING IT THE CAR WILL KNOW LONGER START. I HAVE HAD MY DIESEL EXHAUST FLUID FILLED MULTIPLE TIMES BUT THE MESSAGE RETURNS IMMEDIATELY. TO REPLACE THE DEFECTIVE TANK IS $2,500. I'M MAKING A COMPLAINT BECAUSE AS I SAID THIS IS A WIDESPREAD ISSUE WITH THIS PART AND IF BMW REALIZES THERE IS A DEFECT ON THE MAIN TANK, WHY WOULDN'T THEY ALSO REPLACE THE PASSIVE TANK UNDER EXTENDED WARRANTY?
