NHTSA Complaint #11533976 — 2016 BMW 750I

There are two grill shutter actuators. One for the upper and one for the lower. Different part numbers. NHTSA issued a TSB for N63R in 2019: MC-10160279-9999 (G12 (N63R)/G30 (B58M) RADIATOR GRILL UPPER AND LOWER ACTIVE AIR FLAPS: LIMITED WARRANTY EXTENSION TO 10 YEARS/120,000 MILES). My vehicle is a N62R and there are hundreds perhaps thousands of reports of the IDENTICAL part numbers from BROSE Manufacturing (USA / Germany) failing. For example, my upper failed in APR 2023 after a repair I paid for in SEP 2022 with a P/N manufactured in 2021. Then, the lower actuator failed which has a manufacture date of 2017 (so it is the OEM part). Though the upper actuator is coded to remain open on fault, the lower is for some reason coded to remain closed on fault. If the fault codes are incorrectly interpreted by the [XXX] when the vehicle is in operation, then the engine could quickly overheat and lead to major issues for the occupants, but likely result in thousands of dollars of engine repairs. I urge you to reconsider the TSB and issue a recall/warranty extension for all BMW G11/12/30 and similar (in fact, this part is used on all series with upper and lower shutters: 5, 7 and X from 2015.) The main problem I am having is that there ARE NO PARTS IN STOCK at BMW worldwide. [XXX] has not responded. Thank you. “INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).”
