NHTSA Complaint #11308268 — 2015 BMW X5

I RANDOMLY BEGAN SMELLING FUMES IN VEHICLE WHEN STOPPED AT TRAFFIC LIGHTS. QUESTIONED MY DA AT CLASSIC BMW OF PLANO. HE SAID NOT AIR OR FUEL FILTER, ALL IS OKAY. A COUPLE MONTHS LATER THE CAR ENGINE STOPPED AT RED LIGHT IN THE CITY OF ROWLETT. I WAS ABLE TO GET IT STARTED & INTO A LOT, WOULD NOT CRANK, HAD IT TOWED, DIAGNOSED AS FUEL INJECTORS. MY HUSBAND ADVISED THERE WAS A RECALL, I QUESTIONED BMW USA, SAID ONLY 2011-2014. I REQUESTED ESCALATION TO CONFIRM NO ISSUES WITH 2015, WAS TOLD NOTHING THEY COULD DUE UNLESS REPORTED BY 'MASTER' TECHNICIAN. I WENT FORWARD WITH $1529 REPAIR OF 1 INJECTOR ALTHOUGH RESEARCH INDICATED ALL 6 SHOULD BE REPLACED IF 1 IS BAD. SA INSISTED NOT NECESSARY. BEGAN SMELLING FUMES AGAIN JAN 2020, EXPECTED ANOTHER FI BAD, DIAGNOSED AS CATALYTIC CONVERTER, RESEARCH INDICATES POSSIBLY CAUSED BY BAD FUEL INJECTORS. WANT TO DOCUMENT BECAUSE EXPECTING OTHERS TO HAVE SAME ISSUES AT 85K+. MY MFG WARRANTY ENDED DEC 2020, CAR IS REGULARLY MAINTAINED BY DEALERSHIP YET THEY SAY NO WAY TO PREVENT. I BELIEVE ISSUES ARE RELATED TO THE START/STOP
