NHTSA Complaint #11255354 — 2015 BMW 320I

MY 2015 BMW 320I GAVE ME A WARNING OF CHARGING MALFUNCTION WARNING SO I TOOK MY CAR TO BMW SERVICE FOR AN INSPECTION. THIS WAS IN APRIL 2019. THE SERVICE ADVISOR LET ME KNOW I COULD NEED A NEW BATTERY SO I APPROVED NEW BATTERY IF THAT'S WHAT IT NEEDED. ONCE INSPECTED FURTHER I WAS TOLD THERE WAS AN OIL LEAK AND THAT CAUSED MY DRIVEBELT TO DETERIORATE AND SLIDE OFF BELT TENSIONER. THE OIL LEAK WAS DUE TO NEEDING A NEW OIL FILTER HOUSING GASKET, SO I REPLACED THAT AS WELL. I WASN'T WHAT CREATED THE OIL LEAK ISSUE ONLY THAT I NEEDED TO REPLACE THE BELT TENSIONER, HOUSING GASKET AND DRIVE BELT. I WAS TOLD THIS WAS WHY MY CHARGING MALFUNCTION WARNING CAME ON. MY BATTERY WAS FINE, NO NEED TO REPLACE. 3 MONTHS LATER SEPTEMBER 12TH 2019 THE CHARGING MALFUNCTION WARNING COMES ON AGAIN. THIS TIME I'M TOLD THEY'RE 80% SURE I NEED A NEW BATTERY. SO I APPROVE THE BATTERY AND I RECEIVE A CALL THAT MY CAR NEEDS A NEW ALTERNATOR. THE ALTERNATOR IS NOT CREATING CHARGING VOLTAGE WHICH MAKE MY BATTERY VOLTAGE LOW CAUSING THE CHARGING MALFUNCTION. MY CAR A 2015 BMW, IT IS 4 YEARS OLD. IN THIS LAST YEAR I HAVE HAD ISSUES WITH THE CHARGING MALFUNCTION AND STILL CAN'T FIGURE OUT THE PROBLEM.
