NHTSA Complaint #11296897 — 2016 BMW M4

BMW IS AWARE OF A CRACK DEVELOPING IN A FRONT SUSPENSION CARRIER (ONE EACH LOCATED ON BOTH THE DRIVER'S SIDE AND PASSENGER'S SIDE - TWO TOTAL). BMW HAD TO REPLACE MY PASSENGER SIDE CARRIER UNDER WARRANTY. WHEN I TOOK MY CAR IN FOR AN OIL CHANGE, THE SERVICE TECHNICIAN DETECTED A HAIRLINE CRACK AND ORDERED THE REPLACEMENT PART FROM GERMANY. I DID NOT ASK FOR THE PART TO BE INSPECTED; IT SEEMS THAT BMW HAS INSTRUCTED ITS SERVICE CENTERS TO INSPECT VEHICLES FOR THIS PARTICULAR FAILURE. I ASKED THE SERVICE CENTER TO PROACTIVELY REPLACE THE DRIVER'S SIDE CARRIER, TOO. THEY REFUSED TO DO SO. THE ISSUE WITH CRACKS DEVELOPING IN THE FRONT TWO CARRIERS IS WELL DOCUMENTED (SEE, FOR EXAMPLE: HTTPS://F80.BIMMERPOST.COM/FORUMS/SHOWTHREAD.PHP?T=1550724). I HAVE ATTACHED A COPY OF THE SERVICE RECORD SHOWING REPLACEMENT OF MY PASSENGER SIDE CARRIER. I HAVE ALSO ATTACHED TWO IMAGES SHOWING CRACKS ON THE PART FROM THE LINK PROVIDED ABOVE. I BELIEVE THAT BMW SHOULD BE REQUIRED TO REPLACE THE CARRIERS ON ALL CARS GIVEN THE POSSIBILITY OF FAILURE AND THE KNOWN FAILURE FREQUENCY.
