NHTSA Complaint #11253427 — 2011 BMW X5

I HAVE AN 2011 X5 DIESEL. I GOT ENGINE LIGHT ON BECAUSE OF PASSIVE TANK PROBLEM. I LOVE THE CAR BUT THIS CAR HAS SO MANY SES LIGHTS AFTER I GOT IT. I FIXED ACTIVE TANK OUT OF MY OWN POCKET BEFORE THEY HAD EXTEND WARRANTY FOR ACTIVE TANK. ITS LIGHTS ON AGAIN AND THIS TIME UNDER COVERED. BUT AFTER COUPLE OF MONTH THE PASSIVE TANK GOT PROBLEM. I CALLED BMW BUT THEY SAID IT'S NOT COVERED. IT'S $3000 AGAIN. I TALKED TO DEALER, DEALER SAID IT WILL NOT EFFECT MY DRIVE BECAUSE IT'S A BACK UP TANK (ONLY BE USED IF ACTIVE TANK BROKE) BUT IT WON'T PASS EMISSION TEST. I AM REALLY FRUSTRATED WITH THIS SES LIGHT ON AND I DID LOTS OF RESEARCH ABOUT PASSIVE TANK. LOTS OF PEOPLE HAD SAME PROBLEM AND SOME GOT COVERED BY BMW. I TRIED TO COMMUNICATE WITH BMW ABOUT THE SCR TANK. PASSIVE TANK IS THE SAME COMPONENT AS ACTIVE TANK AND IT'S BACK UP TANK. YOU ALREADY KNOW THESE TANKS HAVE PROBLEM WHY COVER ONLY ONE AND LET COSTUMER PAY THE OTHER ONE. AND WHY SOME COVERED SOME DON'T? THIS IS REALLY NOT FAIR AND I CAN'T PASS EMISSION TEST WITHOUT FIXING THIS ENGINE LIGHT ON. IT'S ALSO REALLY BOTHER'S ME (ENGINE LIGHT ON) WHEN I DRIVE MY CAR EVERY DAY WITH MY KIDS AND DON'T KNOW IT THERE IS ANY OTHER PROBLEM EXCEPT PASSIVE TANK. PLEASE HELP ME ON ANYWAY YOU CAN. THANK YOU SO MUCH FOR YOUR TIME!
